i am working on a project in which i have to handle redundant servers.
There are 2 Sql Servers which are online.one is the primary and the other is a redundant server. The application reads data from primary in normal conditions.But data will be updated to both servers.
in case when primary server goes down the data retrieval is from the redundant server which now acts as the primary server.
i should monitor in either case when the server is up have to synconize data from the other server.For this case i have used DTS to copy/append tables.
My concern is will this update all the data that is to the database,even while there is an update of data during when the DTS is running.
hi, i have one problem to shyncronizing two sql 2005 server databasesmy scenario is like -i have one server that has database say xyz and in other server that has database say abc and i want to synchronize both two way insert , update and deltecan any one have any idea thanks in advacesandip patel
I have developed an application using visual studio 2005 and I am trying to figure out how to store the data on the pda and sync it with a dadabase on the pc. we have a database server but it is only have sql server 2000. i have only been able to find instruction for sqlserver 2005. can anyone help.
My question is regarding syncronization between two databases in MS SQL Server. If we wanted to do MERGE REPLICATION then we can set up pulishers and subscribers using the PS/SQL script (stored procedures) without having to use Enterprise Manager gui tools. I see that after you set all the publishers, distributors and subscribers and you want to start syncronization explicitly the only way you could do is go to Enterprise Manager and find the Publishing/Subscribing Items and right click on them and choost "Start Syncronization" (Sorry I have omitted the nitty-gritty details about how to find those Publishing/Subscribing items in Enterprise Manager).
I am wondering whether we could trigger the start of syncronization using any system stored procedures or without using Enterprise Manager.
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 am using the following select statement to get the row count from SQL linked server table.
SELECT Count(*) FROM OPENQUERY (CMSPROD, 'Select * From MHDLIB.MHSERV0P')
MHDLIB is the library name in IBM DB2 database. The above query gives me only the row count of table MHSERV0P. However, I need to get the names, rowcounts, and sizes of all tables that exist in MHDLIB librray. Is it possible at all?

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
I 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 ?
Hi all, I have a large Excel file with one large table which contains data, i've built a SQL Server DataBase and i want to fill it with the data from the excel file.
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
I have 3 Checkbox list panels that query the DB for the items. Panel nº 2 and 3 need to know selection on panel nº 1. Panels have multiple item selection. 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
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
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.
Ok say I would like to build a table for of the following questions(say 6 questions for the sake of argument): Do I just stored the index of the radiobuttonlist. What are some resources that I could look at. Should I make a look up table.

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, SYSTEM_SCHEME_NAME.SCHEMENAME, CUSTOMER_POLICY_DETAILS.POLICYNUMBER, --TotalPayable IsNull(SUM(CASE LIST_TRAN_BREAKDOWN_TYPE.IncludeInTotal WHEN 1 THEN ACCOUNTS_TRAN_BREAKDOWN.AMOUNT ELSE 0 END), 0) AS TotalPayable, --NetPremium IsNull(SUM(CASE ACCOUNTS_TRAN_BREAKDOWN.Tran_Breakdown_Type_ID WHEN 'NET' THEN ACCOUNTS_TRAN_BREAKDOWN.AMOUNT ELSE 0 END), 0) AS NetPremium, --IPT IsNull(SUM(CASE WHEN SubString(ACCOUNTS_TRAN_BREAKDOWN.Premium_Section_ID, 1, 3) = 'TAX' THEN ACCOUNTS_TRAN_BREAKDOWN.AMOUNT ELSE 0 END), 0) AS IPT, --Fee IsNull(SUM(CASE ACCOUNTS_TRAN_BREAKDOWN.Tran_Breakdown_Type_ID WHEN 'FEE' THEN ACCOUNTS_TRAN_BREAKDOWN.AMOUNT ELSE 0 END), 0) AS Fee, --TotalCommission IsNull(SUM(CASE WHEN SubString(ACCOUNTS_TRAN_BREAKDOWN.Tran_Breakdown_Type_ID, 4, 4) = 'COMM' THEN ACCOUNTS_TRAN_BREAKDOWN.AMOUNT ELSE 0 END), 0) AS TotalCommission

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?
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.
I need to copy data from warehouse tables to master tables of different SQL instances. Refresh need to done once in an hour. What is the best way to do this? SQL agent jobs or SSIS packages?
Hi! 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.
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 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.
Hi, Are there any significant performance benefit if we avoid temp tables? Are the temp tables bad for good performance of queries? Is it better to create table ,then use it after that drop it ,rather then using temp tables?
I want to compare two tables. if the data is existed to the other table i will insert it to other table if not exist it will load also to diffrent table. Example: if my table was Tbl_StudentID and Tbl_FacultyID i want to insert in tbl_Grade if the data in Tbl_StudentID is exist or present in Tbl_FacultyID . And if the Tbl_StudentId is not exist in Tbl_FacultyID the data will move to Tbl_SupervisorID.
