Dynamic Tables.

Apr 30, 2004

hello everyone,





Thank you Darrell for your help on my "Firehose" problem.





Well, I have another question for everyone. I have three tables with the same columns: Products, Products_Sold, and Products_StandBy. I have a Stored Procedures that gets the products: Products_Get, Products_Sold_Get, and Products_StandBy_Get. I want to be able to only have one stored procedure that gets from all tables depending on what @Table variable I give it.





I tried the following, but it didn't work:








CREATE Procedure CMRC_Products_Get


@Table


AS


CREATE TABLE #TempTable


(


ProductID int,


Chest nvarchar (50),


ItemSize nvarchar (50)


)





INSERT INTO #TempTable


(


ProductID,


Chest,


ItemSize


)


SELECT


ProductID,


@Table.Chest,


CMRC_WomensSizes.ItemSize


FROM


@Table INNER JOIN


CMRC_WomensSizes ON @Table.Chest = CMRC_WomensSizes.Chest








I get an error message on the line: "@Table.Chest,"





So, my question would now be, how do I go about doing what I'm attempting here? Anybody? Thanks ahead for any help.





Sincerely,








Alec

Dynamic Tables Names And Temporary Tables Options

Oct 5, 2007

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

Populating A DB From 2 Tables (Dynamic)

Apr 27, 2005

Hi

I am quite new to the complexities of MS SQL and have a problem, I would like to resolve. I have 2 tables with a unique identifier in both and want to populate a new table with information from both, but the second table I would like to populate just some fields that have a DOB eg

Table 1:
uniqueId
Name
Address

Table2:
uniqueId
Type
Setting

example of content for Table 2:
uniqueId Type Setting
123 DOB 03/04/74
234 TFN 12345678
567 POA Mr Smith

So the new table needs to be populated with a ll of info in table 1 and has a new field called DOB so only the clients with a DOB should populate this field, if the client in Table 1 has a TFN reference, this record should be added to the new table but no value needs to be entered eg

123 Chris Smith 1 high street 03/04/74
234 Jon brown 2 high terrace <Null>

Cheers

Ad-hoc Dynamic Query With Multiple Tables

Feb 8, 2005

Hi:
I'm trying to create an ad-hoc query on a Asp.net page for user. Besides the usual Boolean operators, Field Names, Comparison operators & Field Values, the ad-hoc query also involves multiple tables, eg [Customers] , [Members] & [Orders].

Now I have difficulties on writing a TSQL sp on how to take the dynamic query with different tables under consideration. User might simply query each individual tables (eg, Customers with age > 25) or combination of tables (eg, Membered Customers with Orders Amt > 1000 between 1/1/2005 - 1/31/2005)

I have look up a lot dynamic query on the net but all are with only 1 single table to hit. Could anyone give me a direction on how to write a dynamic query script with multiple tables under consideration? Much appreciated.

ps: The ad-hoc query only contains these defined tables, no other table will be involved.

SQL 2012 :: How To Do Dynamic Audit For The Tables

Jul 21, 2014

I would like to do a dynamic audit for the tables ( columns which needs to audited will also change dynamically). For example,

I am having 3 tables, table1 table2 table3

User can select Table 1 ( col 1, col3, col4) and Table2 ( col 3 and col 5).

I want to achieve this functionality without any triggers or output clause, so only one option which is left is "ChangeDataCapture" ( to my knowledge). So i did a small POC. The problem here is, system captures all the field data even though value doesn't change, for example,

TableA

CountryId CountryCode CountryName
1 IND INDIA
Update TableA
Set CountryCode = 'INDI', CountryName = 'INDIA'
Where CountryId = 1

On running the above query, CDC stores the value for both the columns, but i don't want this. I only wanted to store the CountryCode value alone.

CREATE TABLE [dbo].tCountry(
CountryId bigint IDENTITY(1,1) NOT NULL Primary Key,
CountryName [varchar](50) NULL,
CountryCode [varchar](50) NULL,
CreateBy bigint
)
EXEC sys.sp_cdc_enable_db

[code]....

--See here, i want to display CountryName as NULL, because i didnt do any changes in this column

--Why am i asking this bcoz, Frm my front end application, i will send the complete list of columns and the values to the update query.

Select * from cdc.dbo_tCountry_CT Where __$operation in (3,4)

SSIS DYnamic Temp Tables

Nov 27, 2006

Hi,

I have a database with serveral tables, for example 'customer', I want to update this table with a SSIS package. However, to ensure we don't have issues if the update fails then I've put in an intermediate stage

Using an Execute SQL Task I create temporary tables, for example 'customer_tmp'. Data is then imported into these tables. When all the data is imported successfully the original tables are dropped and the temporary tables are renamed, removing the '_tmp'

This works fine and I'm happy with it. However, if someone adds a column to one of the tables in SQL server it is lost on the next upload.

Similarly I have to hard code creating the indexes into the package as well.

Does anyone know how I could copy the original table definitions and create the temporary tables dynamically. So that any new columns would be picked up?

And indeed is it possible to copy the indexes from one table to another before the drop and rename trick?

Thanks in advance.

Iain

Dynamic List Of Tables In Integration Services

Apr 27, 2006

I need to report on data from several databases on several servers. They are all SQL Server 2005 databases. I am trying to created an Integration Services task to consolidate and transform this data for easy reporting. The problem I am having is one database in particular. It has tables like this:

tblLookupData_Customer1
tblLookupParseData_Customer1
tblLookupData_Customer2
tblLookupParseData_Customer2
tblLookupData_Customer3
tblLookupParseData_Customer3

I want to use only the tables of the form "tblLookupParseData*" for this list. I can do this in Stored Procedures by dynmacally building up the sql query. I cannot find out how to do this in Integration Services. When I make Datasource Views, they seem to expect me to pick from a list of known tables. This list of tables grows as Customers are added to the system.

NOTE: The way the tables are structured was NOT my idea. I hate storing "data" in the structure of the database. Many people also do this when they create "period" tables such as "CustomerData_05_2005". It speeds up writing the data, and querying a specific table, but it is a nightmare for reporting. I cannot change this as it is not in my responsibility.

SQL Server 2012 :: Join Two Dynamic Pivot Tables

Dec 11, 2013

I have two dynamic pivot tables that I need to join. The problem I'm running into is that at execution, one is ~7500 characters and the other is ~7000 characters.

I can't set them both up as CTEs and query, the statement gets truncated.

I can't use a temp table because those get dropped when the query finishes.

I can't use a real table because the insert statement gets truncated.

Do I have any other good options, or am I in Spacklesville?

Including Single Quotes In Dynamic Pivot Tables?

I have this pivot table (I only post the static version as the problem only regards the single quotes)

declare @title1 nvarchar(20)
declare @title2 nvarchar(20)
declare @title3 nvarchar(20)
set @title1 = '1 - too early'

System Tables, Dynamic Management Views: Confused

Feb 4, 2008

As im diving into my new DBA role and reading as much as I can, I am a little confused on DMV's and system tables.
I've been reading through the book "SQL Server 2005 Bible", which has been very helpful. I tend to use it in conjunction with BOL whenever I come across something I want to learn more.

Last Friday, I tinkered around with DMV's, which was really cool, but I ran into something today that confused me.

Basically, it was finding out the recovery model for all the DB's on the server. The code in the book was:


SELECT [name], recovery_model_desc
FROM sys.databases;


Which turned exactly what it says it will.

however, I am confused.
I initially thought I needed to specify something in the "[name]" section, but realized, that is not the case.
My question is, why is that?
How do I know when to use [] around something?

I found this article:

http://www.databasejournal.com/features/mssql/article.php/3587906

I have been reading it.
I guess I am just really young and raw to T-SQL to know when to use the language corectly.

Is it due to the fact that the rules or syntax is a little different when using system tables?

Hope that makes sense.

Thanks.

Dynamic Creation Of Temp Tables Using Managed Code

Jan 23, 2008



Hi,
I have a requirement to create #Temp table in database and insert values to it.

I use following code:

DbCommand dbCreateTable;

dbCreateTable = provider.CreateCommand();

dbCreateTable.Connection = conn;

dbCreateTable.CommandText ="Create table #MyTemp (Id varchar(10))";

dbCreateTable.ExecuteNonQuery();

string[] insertValues = {"Insert into #Mytemp values ('TestString1')",

"Insert into #Mytemp values ('TestString2')"};

DbCommand dbInsertData = provider.CreateCommand();

dbInsertData.Connection = conn;

foreach (String insertStr in insertValues)

{

dbInsertData.CommandText = insertStr;

dbInsertData.ExecuteNonQuery();

}

Code creates the Temp table but when it comes to insert statement, it throws error saying "Temp table not found".
Reason can be Create and Insert statement gets executed as 2 different sessions.
How to get the above requirement work fine?
Thank you.

Importing Excel Sheet Which Have Dynamic Column Name And Dynamic Number Of Columns

Aug 25, 2007

Hi Craig/Kamal,

I got your email address from your web cast. I really enjoyed the web cast and found it to be
very informative.

Our company is planning to use SSIS (VS 2005 / SQL Server 2005). I have a quick question
regarding the product. I have looked for the information on the web, but was not able to find
relevant information.

We are getting Source data from two of our client in the form of Excel Sheet. These Excel sheets
Are generated using reporting services. On examining the excel sheet, I found out that the name
Of the columns contain data itself, so the names are not static such as Jan 2007 Sales, Feb 2007 Sales etc etc.
And even the number of columns are not static. It depends upon the range of date selected by the user.

I wanted to know, if there is a way to import Excel sheet using Integration Services by defining the position
Of column, instead of column name and I am not sure if there is a way for me to import excel with dynamic
Number of columns.

Your help in this respect is highly appreciated!

Thanks,


Hi Anthony, I am glad the Web cast was helpful.

Kamal and I have both moved on to other teams in MSFT and I am a little rusty in that area, though in general dynamic numbers of columns in any format is always tricky. I am just assuming its not feasible for you to try and get the source for SSIS a little closer to home, e.g. rather than using Excel output from Reporting Services, use the same/some form of the query/data source that RS is using.

I suggest you post a question on the SSIS forum on MSDN and you should get some good answers.

SSRS 2005 - Email Report On Execution To Dynamic List With Dynamic Parameters = No Schedule

Nov 23, 2007

Hi,
I have a need to display on screen AND email a pdf report to email addresses specified at run time, executing the report with a parameter specified by the user. I have looked into data driven subscriptions, but it seems this is based on scheduling. Unfortunately for the majority of the project I will only have access to SQL 2005 Standard Edition (Production system is Enterprise), so I cannot investigate thoroughly.

So, is this possible using data driven subscriptions? Scenario is:

1. User enters parameter used for query, as well as email addresses.
2. Report is generated and displayed on screen.
3. Report is emailed to addresses specified by user.

Any tips on how to get this working?

Thanks

Merge Replication W/ Dynamic Row Filter - Not 'dynamic' After First Initial Sync?

May 2, 2007

If anyone could confirm...

SQL Server 2000 SP4 to multiple SQL Server 2005 Mobile Edition on PDAs. My DB on SQL2k is published with a single dynamic row filter using host_name() on my 'parent' table and also join filters from parent to child tables. The row filter uses joins to other tables elsewhere that are not published to evaluate what data is allowed through the filter.

E.g. Published parent table that contains suppliers names, etc. while child table is suppliers' products. The filter queries host_name(s) linked to suppliers in unpublished table elsewhere.

First initial sync with snapshot is correct and as I expected - PDA receives only the data from parent (and thus child tables) that matches the row filter for the host_name provided.

However - in my scenario host_name <--> suppliers may later be updated E.g. more suppliers assigned to a PDA for use or vice versa. But when I merge the mobile DB, the new data is not downloaded? Tried re-running snapshot, etc., no change.

Question: I thought the filters would remain dynamic and be applied on each sync?

I run a 'harmless' update on parent table using TSQL e.g. "update table set 'X' = 'X'" and re-sync. Now the new parent records are downloaded - but the child records are not!

Question: I wonder why if parent records are supplied, why not child records?

If I delete existing DB and sync new, I get the updated snapshot and all is well - until more data added back at server...

Any help would be greatly appreciated. Is it possible (or not) to have dynamic filters run during second or subsequent merge?

Mixing Dynamic SQL With Non-Dynamic In Stored Proc

Mar 24, 2007

I have a Stored Procedure for processing a Bill of Material.

One column on the Assembly Table is a Function Name that contains some busniess rules.

OK, now I'm doing a Proof of Concept and I'm stumped.

Huuuuh!

I will ultimately have about 100 of these things. My plan was using Dynamic SQL to go execute the function.

Note: The function just returns a bit.

So; here's what I had in mind ...

if isnull(@FnNameYN,'') <> ''
exec spinb_CheckYN @FnNameYN, @InvLineID, @FnBit = @FnBit output




CREATE PROCEDURE dbo.spinb_CheckYN
@FnNameYN varchar(50),
@InvLineID int,
@FnBit bit output
AS

declare @SQL varchar(8000)

set @SQL = '
if dbo.' + @FnNameYN + ' (' + convert(varchar(31),@InvLineID) + ')) = 1
set @FnBit = 1
else
set @FnBit = 0'

exec (@SQL)
GO



Obviously; @FnBit is not defined in @SQL so that execution will not work.
Server: Msg 137, Level 15, State 1, Line 4
Must declare the variable '@FnBit'.
Server: Msg 137, Level 15, State 1, Line 5
Must declare the variable '@FnBit'.


So; is there a way to get a value out of a Dynamic SQL piece of code and get that value INTO my OUTPUT variable?


My many thanks to anyone who can solve this riddle for me.
Thank You!


Sigh: For now, it looks like I'll have a huge string of "IF" statements for each business rule function, as follows:
Hopefully a better solution comes to light.

------ Vertical Build1 - Std Vanes -----------
if @FnNameYN = 'fnb_YN_B1_14'
BEGIN
if dbo.fnb_YN_B1_14 (convert(varchar(31),@InvLineID) ) = 1
set @FnBit = 1
else
set @FnBit = 0
END

------ Vertical Build1 - Scissor Vanes -----------
if @FnNameYN = 'fnb_YN_B1_15'
BEGIN
if dbo.fnb_YN_B1_15 (convert(varchar(31),@InvLineID) ) = 1
set @FnBit = 1
else
set @FnBit = 0
END
.
.

Why Would Tables Pulled In From ODBC In Access Be Different Than Tables In SQL 2005 Tables?

Jan 24, 2008

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?

Thanks,

Dynamic Columns For Dynamic SQL

Mar 9, 2007

I have created a dynamic SQL program that returns a range of columns (1 -12) based on the date range the user may select. Each dynamic column is month based, however, the date range may overlap from one year to another. Thus, the beginning month for one selection may be October 2005, while another may have the beginning month of January 2007.

Basically, the dynamic SQL is a derived Pivot table. The problem that I need to resolve is how do I now use this dynamic result set in a Report. Please keep in mind that the name of the columns change based on the date range select.

I have come to understand that a dynamic anything is a moving target!



Please advise.

Track The Changes To Normalised Tables And Update The Denormalised Tables Depending On The Changes To Normalised Tables

Dec 7, 2006

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
