Is it possible to relate two tables (in the same db) using the PK (int) from one table to a UK (int, allownulls=No) from another?
I've tried, but had no success. Both tables are empty, so there is no way of having a null in the UK column that would prevent relating it to a PK. Just wanted to know if such relation is even possible before spending additional time on figuring out how to do it...
Hi,
I am trying to relate two tables but both are from different databases. I have a database 'Current' which has a table 'case' and another database 'Org' which has a table 'employee'. I want to establish a one-to-many relationship between employee and case. I created a coulmn 'employee_key' in the case table & entered values matching the pkey of the employee table. Then I wrote a query using joins to access the table records.
select Org..employee.pkey, Current..case.assignedengineer, Current..case.pkey from Current..case join Org..employee on Current..request.employee_key=Org..employee.pkey
Although the above query works fine, there is no relation between the two tables of the two databases, I wanted to know if this is the right way to achieve what i want to or is there a way in which i can actually create a relationship between tables of two different datbases. Can anyone suggest/help???
Also, I wanted to know if i can relate 1 table of SQL Server db with another table of Oracle DB. Please help ...........
Thanks
I'm currently setting up a Tabular Model to do some research between several fact tables. Â In this example i have two fact tables (table 1 and table 2)Â which I've created a 1 to 1 relationship on phone number. Â Typically I create a relationship between these tables to find common data between the two. Â However, in this case I am trying to figure out the best way to model the data so that I can easily surface data from one table that does not exist in the other. Â I would liken this to a LEFT JOIN or a WHERE NOT EXISTS in SQL.
Table 1 has all of the data and Table 2 Only has a subset of the data from Table 1. Â What I'm trying to do here is display what attributes in Table 1 may play a part in records not existing in Table 2. What is the best way to model this?
Hi,
I have couple of DBF files.. and when i get them into my scrub database the datatype for all the fields in char. but after i scrub the data i put them into a money feild.. so that if so that i can do any calculations that i want in the report...
Suppose if i keep as a char or varchar in my production database... is it possible to any calculation on it in my report.. just simple additions... and if yes... do i need to convert them into anything before doing the additions... The reason i am asking this is Some of the fields in the scrub database are empty and i want to keep them the same in my production database instead of showing 0.00 as a default.
Any help will be appreciated.

hello experts
i have two sql select statements that selects data from two different tables. I want to concatenate these two sql queries into one singl query (through programming only not through joins). After concatenation i want to sent the single created query to my transection function so that it can select data from two different tables.
How can i acomplish this in vb .net or c#
thanks

I am attempting to determine if a record for TODAY has been written. If one, I update it. If no records for TODAY have been created yet, I INSERT a new one. I am basing my "if" (C#) on a Select count(*) WHERE as shown below. My problem is that I do not know how to obtain the result. The debugger displays a -1 as the count and the IF falls through to its companion ELSE. Can anyone please set me straight? Oh, I build 'TestDate' from getdate and it ends up as a str like "6/10/2008". The Date column is also a varchar with the same kind of string as its contents.String fpsqlA = ("SELECT count(*) from DailyCounts WHERE Date = '"+testDate+ "'");
SqlCommand fpcmdA = new SqlCommand(fpsqlA, connStringDaily);fpcmdA.CommandType = CommandType.Text;
int iCount = fpcmdA.ExecuteNonQuery();SqlDataAdapter ad1 = new SqlDataAdapter(fpcmdA);
ad1.Fill(dtA);
//Test to see if a record for 'today' has already been written to the DailyCounts table. if (iCount <= 0)

Hi all,
I am still relatively new to the SQL world, and have just started looking at purging data from my databases which is older than 8 years old. I am using a routine from another forum on here to get a before Table size pre purge, and then running it again to get the new size after.
The thing i have found is that even though i have deleted over 1.5 million rows, there is actually no difference in the table size.
I have been looking at the UPDATE STATISTICS on the msdn web pages to see if i need to run this to update the information i am using for size comparisons, but it doesnt really tell me if this is one of the things that it updates, and was wondering if i was being dumb and missing something completely obvious here. The other thing i can think of is that even though the data has been deleted, the space has been retained in the indexes on the tables, and until i do a re-index i will not realise the space savings?
Many thanks in advance, and feel free to point and snigger if i have just missed something staring me in the face

hi!
i have some what a definition table of the fields of the other table
name as DefinitionTable with data as follows
FieldType FieldName1 FieldDesc TxtColor FontStyle
8 FIELD1 ABC #1111 [fsbold]
8 FIELD2 CDE #2222 [fsitalic]
8 FIELD3 EFG #3333 [fsbold]
OrigTable
OrigKey FieldType FIELD1 FIEDL2 FIELD3 Results
1 8 test1 test2 test3 ok
so the e.g. FIELD1 is a data in DefinitionTable and a field name in OrigTable..
my problem is how to get the TxtColor in merging this table.. my sp in fetching the data but only the fielddescription is
create procedure Definition
@SearchKey int,
@FieldTypeint
as
begin
DECLARE @FieldName varchar(10),
@FieldDesc varchar(30),
@TextColor int,
@mysql varchar(4000)
SET NOCOUNT ON
SELECT @mysql = 'select o.origkey, '
DECLARE MyCursor CURSOR READ_ONLY FOR
SELECT FieldName1, FieldDesc FROM DefinitionTable
WHERE FieldType = @ResultType
Open MyCursor
FETCH NEXT FROM MyCursor INTO @FieldName, @FieldDesc
WHILE @@FETCH_STATUS = 0
BEGIN
select @mysql = @mysql + 'o.' + @FieldName + ' as ' + @FieldDesc + ', '
FETCH NEXT FROM MyCursor INTO @FieldName, @FieldDesc
END
CLOSE MyCursor
DEALLOCATE MyCursor
select @mysql = @mysql + ' o.results from OrigTable o where
FieldType = ' + @ResultType
execute(@mysql)
end
the result is Ok as
OrigKey ABC CDE EFG Result
8 test1 test2 test3 ok
But the problem is how to include the TxtColor or concatenate TxtColor with this output below
OrigKey ABC CDE EFG Result
8 test1+##1111 test2+#222 test3+#3333 ok
thanx,
mygt
EDIT: Please skip over this and go to the 2nd post. After writing this, I realized it may be too complicated to comprehend, so I tried to simplify with another example which is found in the 2nd post. Or if you want you can read this one and try to understand it.
I would like to go over a design we came up with to handle a certain reporting requirement from an OLAP cube to see if this is a good approach. Also, I would like to hear about other designs that we can consider.
Here is the condensed version of the requirement.
We are measuring the performance of a bunch of portfolios. So among other dimensions, we have a portfolio dimension that holds the list of portfolios we are tracking. In a typical portfolio analysis, an analyst almost always looks at a portfolio's measures along side a benchmark portfolio's measures. A benchmark is another portfolio against which a selected portfolio is compared. So, for a given portfolio, there is a determined benchmark portfolio.
For example, an analyst might want to look at a measure called Annual_Yield for a portfolio called Portfolio_A. There will be an attribute on the member Portfolio_A that tells us what its benchark portfolio is. That attribute will basically be another member from the portfolio dimension. So, as a function of what an analyst chooses as the first portfolio (the subject portfolio), the cube should be smart enought to know what to select as the second portfolio (the benchmark portfolio).
To implement this, I am proposing the following structure for the table that will create the portfolio dimension.
PortfolioID, PortfolioName, Attr1, Attr2, ..., AttrN, BenchMarkID
1, Portfolio_A, blah, blah, ...., blah, 3
2, Porfolio_B, blah, blah, ...., blah, 3
3, Portfolio_C, blah, blah, ...., blah, null
4, Portfolio_D, blah, blah, ...., blah, 3
5, Portfolio_E, blah, blah, ...., blah, 6
6, Portfolio_F, blah, blah, ...., blah, null
So, the above data says that Portfolios A, B, and D uses Portfolio C as their benchmarks. And Portfolio E uses Portfolio F as its benchmark. Lastly, if a portfolio is used as a benchmark for other portfolios, then its BenchmarkID is null, meaning it doesn't get compared to anything, thus Portfolios C and F have null BenchmarkIDs. With this data, I would create a hierarchy in the portfolio dimension that has two levels. At the top level, there will be a portfolio and if that portfolio has a benchmark, then it will drill down to it.
With a portfolio dimension designed as such, I envision a fact table that looks like the following.
PortfolioID, SomeOtherDimIDs,....., Annual_Yield
1, , blah, ,....., 10%
2, , blah, ,....., 7%
3, , blah, ,....., 0%
4, , blah, ,....., 15%
5, , blah, ,....., 20%
6, , blah, ,....., 9%
So, going back to the original report which was looking at Annual_Yield by Portfolio_A, I would do an MDX statement such as
With Set [PortfolioAndBenchmark] As
DESCEDANTS(Portfolio_A)
Select
[Annual_Yield], [PortfolioAndBenchmark] On Columns,
Whatever Other Dimension On Rows
From
[Cube]
Does this make sense? The only concern I have is that I don't want the measures to aggregate along the portfolio hierarchy.
Our mobile application using VS2005 with VB.net is ready and we are trying to set up the SQL CE on the server to test the remote connection procedures. Sql 2005 is based on a dedicated server and is accessed via the Web server which does not have Sql installed on it. We have installed the Sql Server Me Server Tools on the Web server and configured the Virtual directory with IIS. What we cannot get our heads around is how we link the database on the separate Sql server via the web server. When the Pda contacts the Web server via IIS we somehow need to redirect to the dedicated Sql server as it cannot be contacted outside of our network. We have been told that Sql Ce can link with an existing Sql 2005 database, how can we do this?

I'm new to my company, although not new to SQL 2005 and I found something interesting. I don't have an ERD yet, and so I was asking a co-worker what table some data was in, they told me a table that is NOT in SQL Server 2005's list of tables, views or synonyms.
I thought that was strange, and so I searched over and over again and still I couldn't find it. Then I did a select statement the table that Access thinks exists and SQL Server does not show and to my shock, the select statement pulled in data!
So how did this happen? How can I find the object in SSMS folder listing of tables/views or whatever and what am I overlooking?

We have 20 -30 normalized tables in our dartabase . Also we have 4tables where we store the calculated data fron those normalised tables.The Reason we have these 4 denormalised tables is when we try to dothe calcultion on the fly, our site becomes very slow. So We haveprecalculated and stored it in 4 tables.The Process we use to do the precalcultion, will get do thecalculation and and store it in a temp table. It will compare the thetemp with denormalised tables and insert new rows , delte the old oneans update if any changes.This process take about 20 mins - 60mins. Ittakes long time because in this process we first do the calculationregardless of changes and then do a compare to see what are changed andremove if any rows are deleted, and insert new rowsand update thechanges.Now we like to capture the rows/columns changed in the normalisedtables and do only those chages to the denormalised table , which weare hoping will reduce the processing time by atleast 50%WE have upgraded to SQL SERVER 2005.So We like to use the newtechnology for this process.I have to design the a model to capture the changes and updated onlythose changes.I have the list of normalised tables and te columns which will affectthe end results.I thought of using Triggers or OUTPUT clause to capture the changes.Please help me with the any ideas how to design the new process

I'm working on an ASP.Net project where I want to test code on a localmachine using a local database as a back-end, and then export it tothe production machine where it uses the hosting provider's SQL Serverdatabase on the back-end. Is there a way to export tables from oneSQL Server database to another in such a way that if a table alreadyexists in the destination database, it will be updated to reflect thechanges to the local table, without existing data in the destinationtable being lost? e.g. suppose I change some tables in my localdatabase by adding new fields. Can I "export" these changes to thedestination database so that the new fields will be added to thedestination tables (and filled in with default values), without losingdata in the destination tables?If I run the DTS Import/Export Wizard that comes with SQL Server andchoose "Copy table(s) and view(s) from the source database" and choosethe tables I want to copy, there is apparently no option *not* to copythe data, and since I don't want to copy the data, that choice doesn'twork. If instead of "Copy table(s) and view(s) from the sourcedatabase", I choose "Copy objects and data between SQL Serverdatabases", then on the following options I can uncheck the "CopyData" box to prevent data being copied. But for the "CreateDestination Objects" choices, I have to uncheck "Drop destinationobjects first" since I don't want to lose the existing data. But whenI uncheck that and try to do the copy, I get collisions between theproperties of the local table and the existing destination table,e.g.:"Table 'wbuser' already has a primary key defined on it."Is there no way to do what I want using the DTS Import/Export Wizard?Can it be done some other way?-Bennett
View 3 Replies View RelatedI have a trade data tables (about 10) and I need to retrieve information based on input parameters. Each table has about 3-4 million rows.
The table has columns like Commodity, Unit, Quantity, Value, Month, Country
A typical query I use to select data is "Select top 10 commodity , sum(value), sum(quantity) , column4, column5, column6 from table where month=xx and country=xxxx"
The column4 = (column2)/(total sum of value) and column 5=(column3)/(total sum of quantity). Column6=column5/column4.
It takes about 3-4 minutes for the query to complete and its a lot of time specially since I need to pull this information from a webpage.
I wanted to know if there is an alternate way to pull the data from server ?
I mean can I write a script that creates tables for all the input combinations i.e month x country (12x228) and save them in table (subtable-table) with a naming convention so from the web I can just pull the table with input parameters mapped to name convention and not running any runtime queries on database ??
OR
Can I write a script that creates a html files for each table for all input combinations save them ?
OR
Is there exists any other solution ?

Hi,
Currently, I'm using the following steps to migrate millions of records from Foxpro tables to SQL Server tables:
1. Transfer Foxpro records to .dat files and then bcp to SQL Server tables in a dummy database. All the SQL tables have the same columns as the Foxpro tables.
2. Manipulate the data in the SQL tables of the dummy database and save the manipulated data into the SQL tables of the real database where the tables may have different structure from the corresponding Foxpro tables.
I only know the following ways to import Foxpro data into SQL Server:
#1. Transfer Foxpro records to .dat files and then bcp to SQL Server tables
#2. Transfer Foxpro records to .dat files and then Bulk Insert to SQL Server tables
#3. DTS Foxpro records directly to SQL Server tables
I'm thinking whether the following choices will be better than the current way:
1st choice: Change step 1 to use #2 instead of #1
2nd choice: Change step 1 to use #3 instead of #1
3rd choice: Use #3 plus manipulating in DTS to replace step 1 and step 2
Thank you for any suggestion.

Multiple users may use this at the same time and I wanted to have a full separation between the application and the DB. The ASP.net application always uses Stored Procedures to access the DB. Whats the best course of action? Using a permanent 'temp' table on the SQL server? Accomplish everything on the client side?
[Web application being built on ASP.net 3.5 (IIS7) connected to SQL Server 2005)
Firstly I consider myself quite an experienced SQL Server user, andamnow using SQL Server 2005 Express for the main backend of mysoftware.My problem is thus: The boss needs to run reports; I have designedthese reports as SQL procedures, to be executed through an ASPapplication. Basic, and even medium sized (10,000+ records) reportingrun at an acceptable speed, but for anything larger, IIS timeouts andquery timeouts often cause problems.I subsequently came up with the idea that I could reduce processingtimes by up to two-thirds by writing information from eachcalculationstage to a number of tables as the reporting procedure runs..ie. stage 1, write to table xxx1,stage 2 reads table xxx1 and writes to table xxx2,stage 3 reads table xxx2 and writes to table xxx3,etc, etc, etcprocedure read final table, and outputs information.This works wonderfully, EXCEPT that two people can't run the samereport at the same time, because as one procedure creates and writesto table xxx2, the other procedure tries to drop the table, or read atable that has already been dropped....Does anyone have any suggestions about how to get around thisproblem?I have thought about generating the table names dynamically using'sp_execute', but the statement I need to run is far too long(apparently there is a maximum length you can pass to it), and evenbreaking it down into sub-procedures is soooooooooooooooo timeconsuming and inefficient having to format statements as strings(replacing quotes and so on)How can I use multiple tables, or indeed process HUGE procedures,withdynamic table names, or temporary tables?All answers/suggestions/questions gratefully received.Thanks

View 1 Replies View RelatedHello all,
Being still a relative newcomer to SQL Server (people may say I'm trying to take on too much being somewhat inexperienced once they read about the problem I'm trying to tackle, but alas...) I'm running into the following problem: I need to create tables in my user database on the fly (using Stored Procedures) so that each table can be created many times in the database but only once for every user. The tables should be named something like "username.Table1", "username.Table2" etc. as opposed to "dbo.Table1". I then want to use the stored procedure from .NET/C# in my web application, so that i can create the complete set of usertables for each of my clients.
Now, I tackled the stored procedure part (that is, it creates all the tables I need with all the parameters I want) and am able to use it from my web application (which took some time to learn but proved quite easy to do), but I cannot seem to get it coupled to the current user (instead of the dbo). Every time I trie, the tables are created as dbo.Table1 and when I try to create a new set, it gives a warning ("table with name such and so already exists..."). I made sure to log in as an authenticated user (using forms authentication) before trying to create the tables but this gives the aforementioned result.
What am I doing wrong? I use Visual Web Developer Express, SQL Server 2005 Express and IIS version 5.1
Please help :-D

hi. I am very new to databases.
At the moment I have one big database that has column titles such as author, book title, rating, isbn, publisher, publish date, copyright date, graphical image review, availability, genre.
I want to break this large table down into say four smaller relational tables. Partly because it is so large and partly to make it easier to bind the data to the web site. I also want to keep the large table.
How can i do this? I use sql server management express. The database is on my hosts database. I also use VWD 2005 express edition.
thanks for your time

How should I create the database table for the above example.
I have created 3 views, which I then want to join to produce an overall result. The first view returns customer details, along with payment information. The next two views return values only when the customer has purchased extras outside our standard product i.e. if there is no purchase of an extra, then nothing is written to the extra's table. When I join the views together they only return values where data has been matched in all 3 views i.e. extra's have been purchased. Any data that did not match in all 3 view (i.e. no extra's purchased) is either ignored or dropped from the results. So I need my script to return all values even if no data exists in the two extra views.
My scripts are as follows:
Main View
SELECT
CUSTOMER_POLICY_DETAILS.POLICY_DETAILS_ID,
CUSTOMER_POLICY_DETAILS.HISTORY_ID,
CUSTOMER_POLICY_DETAILS.AUTHORISATIONUSER,
CUSTOMER_POLICY_DETAILS.AUTHORISATIONDATE,
ACCOUNTS_TRANSACTION.TRANSACTION_CODE_ID,
CUSTOMER_INSURED_PARTY.SURNAME,
SYSTEM_INSURER.INSURER_DEBUG,

I have included all the scripts I have used, as others may find them useful, in addition to anyone that is able to provide me with some assistance. Thanks in advance for for the help.
I have facing a design problem and unable to justify which design to choose for my data model.
Usually, what we have is like data tables and reference tables to store data in those data tables.
My database has tables with 20-30 columns in them. And most of them (though not all of them), stores data from some reference tables. Meaning each column has an associated reference table where it stores possible list of values for that particular column. Sort of data domain for that column. FYI, My database is related to medical field.
For example, A table that has a varchar(40) column called "Differentiation". It can only store values from following list:
- Undifferentiated
- Moderate
- Poor
- Poor - Moderate
- Moderate - well
Now, to implement this, simple solution would be to have a reference table where I can store all these possible values...And then have just a reference of each data item into my "Differentiation" column in the table.
This is simplest and probably the best solution for such thing and i can also have referential integrity implemented for this.
But now if we look at the bigger picture, my database is growing and I have about 80 tables which I need to create where most of the columns will have different reference tables like I mentioned above. Approximate number of reference tables is 300 tables. All the reference table will have same structure, with different values for different columns.
Now, what seems to me is, because the table structure is same for every column, rather than having 300 different tables, I can only have 2 tables, where I can put all these reference values into these 2 tables.
Like,
Table 1 :
This table can have name of the reference table like "differentiationlist" etc.
Table 2:
It has reference to the reference table list in Table 1 discussed above and all the values that are part of that reference table can go in this table with its reference.
But problem with this is, because all the reference tables are in these two tables, I don't know how to implement referential integrity in this design.
Does anyone have any idea or solution for situation like this?
Thanks,

I have a table that I am basically reduplicating a couple of times for each part of this database that I want to create.Each table basically has the same data: The tables will be called motherTable, fatherTable, sonTable, daughterTable and so on.I am pretty much using the following in each column: UserID, MotherID(or FatherID or SonID, etc., etc. and so on for each unique table), FirstName, LastName, MiddleName, BirthPlace, Photo, Age.I don't see an option to copy a table and just modify the second ID part and rename that table accordingly.How can I make this an easier way of creating these similar tables without retyping all these columns over and over again?Thanks in advance.

View 3 Replies View RelatedHi! I have a general SQL CE v3.5 design question related to table/file layout. I have an system that has multiple tables that fall into categories of data access. The 3 categories of data access are:
1 is for configuration-related data. There is one application that will read/write to the data, and a second application that will read the data on startup.
1 is for high-performance temporal storage of data. The data objects are all the same type, but they are our own custom object and not just simple types.
1 is for logging where the data will be permanent - unless the configured size/recycling settings cause a resize or cleanup. There will be one application writing alot [potentially] of data depending on log settings, and another application searching/reading sections of data.
When working with data and designing the layout, I like to approach things from a data-centric mindset, because this seems to result in a better performing system. That said, I am thinking about using 3 individual SDF files for the above data access scenarios - as opposed to a single SDF with multiple tables. I'm thinking this would provide better performance in SQL CE because the query engine will not have alot of different types of queries going against the same database file. For instance, the temporal storage is basically reading/writing/deleting various amounts of data. And, this is different from the logging, where the log can grow pretty large - definitely bigger than the default 128 MB. So, it seems logical to manage them separately.
I would greatly appreciate any suggestions from the SQL CE experts with regard to my approach. If there are any tips/tricks with respect to different data access scenarios - taking into account performance, type of data access, etc. - I would love to take a look at that.
Thanks in advance for any help/suggestions,
Bob
Has anyone seen this error? It comes up when my app executes a select statement via linked server (from MSSQL 2000 to 2005) the second time it runs. It's basically a timed poll of tables in the remote database. It works once but the second time it executes I get the error from the remote db, it's just a select but I guess the cursor is still open so it can't run again. After the exception the select will run again, once and it just repeats. I have researched it a little and it looks like it mostly has to do with the isolation level of the transaction. Unfortunately based on the componet being used to access the database I don't beleive I have the ability to use transact SQL to call the isolation level (s) listed.
Here's the weird part though, at another site the same scenario is running fine. Same primary and remote db versions of MSSQL as well as the application and it runs fine. I guess my question is what type of setup parameters that may be defined in MSSQL 2005 for the remote database might make it behave in this manner in one instance and not the other? TIA in advance for any thoughts/assistance.

I'm doing DTS and need to write a SQL Query for what data have to move and what data have to deleted
I have many tables need to difference query. this one is one of tables
Table-Account0
column EAIndex �BillerCode�ChainCode�PostDate�PostAmount�BalanceDate�BillBegDate�BillEndDate�BillCount�ChAmount
Table-Biller
CompanyCode�BilerCode�BillerName�UniformNo�BusCode�AcctNo�BillerInfoList
Table-DataBackup
column CompanyCode�Keepmonth
when I'm doing SQL DTS, in Table Account0 , I need to select the data which BalanceDate is < today's Date-6
---------------------------------------------------------------------------------------------------------------------
my sql query is below . but it didn't works , I must did somehing wrong with this query pleae point me to correct it
SELECT ZT_EAccount0.*, ZT_DataBackup.KeepMonthFROM ZT_EAccount0 INNER JOIN ZT_Biller ON ZT_EAccount0.BillerCode = ZT_Biller.BillerCode CROSS JOIN ZT_DataBackup on ZT_EAccount0.BalanceDate < getdate()-6
-----------------------------------------------------------------------------------------------------------------------
thank you very much
I was wondering if there is any performance difference between creating an actual table in a DB and inserting records in a Stored Procedure vs. creating a temp table in the Stored Procedure (i.e. CREATE TABLE #MyTempTable .....) and inserting records.I need to create one of those massive "everything in the database, hundreds of pages ", overview reports, which consists of about 40 elements of caclulated data per product. It will be three levels deep:Generic Example:1. Calculated data elements for Cars.2. Calculated data elements for all of a Car's Parts.3. Calculated data elements for all of a Car's Part's Components.Example Report Format:Product Curr 12 Months Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec YTD PrevYtd %Change--------------------------------------------------------------------------------------------------------------------------------------------------Car1 Element1 Element2 Element3Car Part1 Element1 Element2Car Part2 Element1 Element2Car Part3 Element1 Element2Car PartN Element1 Element2 Car Part Element1 Car Part Element2 Car Part Element3 Car Part ElementN------------------------------------------Car2 Element1 Element2 Element3... etc As of now, I completed part 1 above, and the SP takes about 10 minutes to run. It is using a T-SQL created temp table (#MyTempTable). I was wondering, before I recode anything, if anyone knows if my SP will run faster if I actually create the table in the DB instead? I figure that once I complete parts 2 and 3 above, the SP could take 45 minutes to run.
