Selecting Database Dynamically (as A Variable)

Jun 2, 2006

Hey all.



I need to call another database in the same server dynamically; creating a varible off it or somehow. Example:



-- In database DBaseA

declare @dbname as varchar (30)

set @dbname='[DBaseB].[dbo]'

select * from @dbname.[table2]



I know this block of code doesnt work. And i need a way of making the  database DBaseB dynamic.

DBaseA and DBaseB are in the same server. I am using Sql Server 2000.

How do i solve this? Solutions ?

Dynamically Selecting Tables In OLEDB Source

Mar 17, 2008

hello guys,

I have 10 tables, table1, table2, table3, table4.......table10. all these tables have different structure.
From each of these tables I want extract data and dump into flat file csv.

So i have OLEDB source and FlatFile Destination.

If i write seperate data flow task for each of the tables, then there is no issue.

But i want to use a single data flow task for all these tables. So for this, i use a variable @SQLStr . And i dynamically set the value of this variable to select * from table1, select * from table2.........selct * from table10.

So in the OLEDB source I select Data Access Mode as : SQL Command from variable. And I use @SQLStr for this varible.

For Destination, i dynamically generate the flat file for each of the table.

But this doesnt work, i get validation errors.

So, first can i use a single data flow task to dynamically change the source(different source tables) and destination. If so, what i am missing in the above process?

any help appriciated.

Thanks

SQL Server 2012 :: Dynamically Create A Script Only Selecting Columns Where There Is Data?

Dec 2, 2013

I have created some dynamic sql to check a temporary table that is created on the fly for any columns that do contain data. If they do the column name is added to a dynamic sql, if not they are excluded. This looks like:

If (select sum(Case when [Sat] is null then 0 else 1 end) from #TABLE) >= 1 begin set @OIL_BULK = @OIL_BULK + '[Sat]' +',' END However, I am currently running this on over 230 columns and large tables 1.3 mil rows and it is quite slow. How I can dynamically create a sql script that only selects the columns in the table where there is data in a speedier manner. Unfortunately it has to be on the fly because the temporary table is created on the fly.

Declare Variable Dynamically

Jul 23, 2005

I'm attempting to modify some Crosstab generating code, and I need someadvice/examples.Currently, the code uses a single string variable to store thedynamically generated query (www.johnmacintyre.ca). The problem is thatI am trying to pivot biological taxonomy information, and may end upwith a table containing over 200 columns. This takes the dynamic stringwell over the 8000char limit for variables.[color=blue]>From my understanding, the EXEC() command does not have the 8000char[/color]limit if the execution string is broken into chunks, and concatenatede.g. EXEC(sql1 + sql2 + sql3 + ...). So the solution I think I need isto:1) start a counter at the beginining of the dynamic generation2) append the counter value to the end of a string variable name3) DECLARE the new variable and attach that loop cycle of text to it,or attach each chunk of characters < 80004) build the EXEC() string by concatenating each dynamic varibleCan this be done? Should it be done? Is there a better way to addressthis type of problem?Thanks for any ideas or insightsTim Pascoe

drop table test
create table test
(
id varchar(10) not null,

Altering A Connection Manager Dynamically Via A Variable

Mar 29, 2006

Within an SSIS Package, we are trying to change the connection string of an output file connection manager at runtime (used for package logging).

To do this, we have defined variables with package-level scope and set the connection manager connection string to this variable. The first step of the package is to set these variables. The second step begins the rest of the package operations (moving data). The package executes successfully, but the log file is never created/appended to.

When the package is debugged, I can verify that the variables are being set correctly in the script task and that the variable values are being passed to the connection manager data sources.

Any ideas why this isn€™t working?

More Selecting Into Local Variable With Dynamic Select...

May 25, 2004

Not wishing to derail the other recent thread on loading a local variable, I've posted this query (hee,hee,hee...I kill me) on a separate thread...though I think I am trying to do something similar...that is to build a dynamic select statement, but return a count of the rows it finds/doesn't find to a local variable...using the (amazingly timely) responses above, I tried this:

Note that the local variables @TargetDate and @TLevel are necessary because they are being passed into the procedure as variables....

DECLARE @SQLCmd varchar(256)
DECLARE @TargetDate smalldatetime
DECLARE @TLevel int
DECLARE @n int
SET @TargetDate = '2004-05-24'
SET @TLevel = 1


SET @SQLCmd = 'SELECT @n = count(*) FROM EventLog WHERE ((CONVERT(varchar(10), [Date], 101) = ''' +
CONVERT(varchar(10), @TargetDate, 101) + ''') AND (MsgLevel = ' +
CONVERT(varchar(3), @TLevel) + '))'
exec (@SQLCmd)
if @n > 0
print 'yep'
else print 'nope'

and, it's TRYING to work...but apparently the local variable @n is not recognized in the execution of the dynamic statement, as this is the output:
Server: Msg 137, Level 15, State 1, Line 1
Must declare the variable '@n'.
nope

Thoughts?

Selecting Version Of Remote SQL Instance Into Local Variable?

Feb 28, 2007

Hello all,
I'm a bit new to SQL Server and T-SQL (my background is in DB2), so hoping you can help me with this. I'm writing a T-SQL script that's hopefully going to scan a bunch of SQL server instances and record the results. We've got a mix of SQL2K and SQL2K5 instances, and for part of my script I only want to run something if the remote instance is SQL2K.

I'd tested this on my local PC with several instances created and it worked fine. When I try and run it for instances located on other servers it barfs :eek: . From what I've found from looking up the error message it looks like I've got myself a loopback -- but I don't know how to get around it - any ideas please?


DECLARE @tempdata TABLE (scratch sql_variant)
DECLARE @debug tinyint
DECLARE @server sysname
DECLARE @version varchar(20)

SET @debug=1
SET @server='SQLSERVER_INSTANCE'

INSERT INTO @tempdata (scratch) EXEC ('[' + @server + '].master.dbo.sp_executesql N''SELECT SERVERPROPERTY(''''ProductVersion'''')''')
SELECT @version = convert(varchar(100),scratch) from @tempdata
DELETE FROM @tempdata
IF @debug>0 BEGIN PRINT @server + ' is running SQL Server version: ' + @VERSION END
IF charindex('8.00',@version) > 0 BEGIN
PRINT 'SQL2K-only code goes here'
END


The error I get is:
OLE DB provider "SQLNCLI" for linked server "SQLSERVER_INSTANCE" returned message "The transaction manager has disabled its support for remote/network transactions.".
Msg 7391, Level 16, State 2, Line 1
The operation could not be performed because OLE DB provider "SQLNCLI" for linked server "SQLSERVER_INSTANCE" was unable to begin a distributed transaction.


I get this error running from a SQL2K5 instance against both SQL2K or SQL2K5

TIA, moff.

Selecting X Records From Table N Times According To Variable Criteria?

Jul 20, 2005

Hi All,Sorry if the subject line is too obscure -- I couldn't think of a wayof describing this request.I have a table that contains approximately 1 million records.I want to be able to be able to select the top x records out of thistable matching variable criteria.Pseudo table records:custid, category, segment1,1,12,1,13,1,14,1,15,1,26,1,27,1,28,1,29,2,110,2,111,2,112,2,113,2,214,2,215,2,216,2,217,2,318,2,319,2,320,2,3So, what I'm trying to do is return a recordset, for example, thatcontains the top 2 of each variation of category and segment.ie:1,1,12,1,15,1,26,1,29,2,110,2,113,2,214,2,217,2,318,2,3The only way I can think to achieve this is in a while statement,performing individual selects against each combination, feeding thewhere criteria by variables that I automatically increment.I can't help thinking there's a much more graceful way of achievingthis?If anyone can give me any insight into this I'd be incrediblyappreciative!Many thanks in advance!Much warmth,Murray

Selecting The Database Name.

Oct 10, 2000

Can anyone help me in finding out the database name?
For example, @@SERVERNAME gives you the name of the server
on which you SQL Server is running.
In the same way, is there any global variable which gives me the
name of the database in the context in which I am running my queries or stored procs?

Thanks

Selecting The Most Recently Edited Item AND Selecting A Certain Type If Another Doesn't Exist

Sep 20, 2007

I've got a big problem that I'm trying to figure out:
I have an address table out-of-which I am trying to select mailing addresses for companies UNLESS a mailing address doesn't exist; then I want to select the physical addresses for that company. If I get multiple mailing or physical addresses returned I only want the most recently edited out of those.

I don't need this for an individual ID select, I need it applied to every record from the table.

My address table has some columns that look like:
[AddressID] [int]
[LocationID] [int]

[Type] [nvarchar](10)
[Address] [varchar](50)
[City] [varchar](50)
[State] [char](2)
[Zip] [varchar](5)
[AddDate] [datetime]
[EditDate] [datetime]

AddressID is a primary-key non-null column to the address table and the LocationID is a foreign key value from a seperate Companies table.
So there will be multiple addresses to one LocationID, but each address will have it's own AddressID.

How can I do this efficiently with perfomance in mind???

Thank you in advance for any and all replies...

Problem Creating Database Dynamically

Jul 29, 2004

Hi everybody,

I have a problem. When I try to create a database with this code:

strConnection = "server=(local);Integrated Security=SSPI"
objConnection = New SqlConnection(strConnection)
objConnection.Open()
Dim strSQL = "CREATE DATABASE xxxxxx ON PRIMARY"
strSQL += "(Name=test_data, filename = 'xxxxx.mdf', size=3,"
strSQL += "maxsize=5, filegrowth=10%)log on"
strSQL += "(name=mydbb_log, filename='xxxxx.ldf',size=3,"
strSQL += "maxsize=20,filegrowth=1)"
objCommand = New SqlCommand(strSQL, objConnection)
objCommand.ExecuteNonQuery()

it usually works, except when the name of the database (xxxxxx) contains a number in the beginning of the name or if it is all made up completely by numbers. I also converted the database name into a string, but it doesn't work either.

What is the problem?
How can I solve it?


Thanks in advance

Create And Then USE A Dynamically-named Database?

Nov 2, 2006

I have a need to create a database, and then populate it. However, thecode below doesn't work as I hoped it might (it creates the table inthe "master" database, which is Not A Good Thing). I know already(thanks Tony!) that if you use Dynamic SQL for the USE command, thenthe subsequent operations need to be Dynamic SQL as well, which is apity since there are over 11,000 lines of it and I don't really fancydebugging it!Does anyone have a cunning plan? In a nutshell, I would like to beable to:1. Create a new database with a derived name - as in the case below aname based on the year, though it might be month as well.2. Create and populate tables in this new database.These operations would ideally be running from a scheduled job.Any thoughts?TIAEdward====================================USE MASTERDECLARE @DBName VARCHAR(123)SET @DBName = 'MyTest_' + CAST((Year(Getdate())) AS Varchar)if not exists(select dbid from master.dbo.sysdatabases where name =@DBName)exec('CREATE DATABASE ' + @DBName)elseraiserror('Database already exists.',3, 1)EXEC ('USE ' + @DBName)if exists (select * from dbo.sysobjects where id =object_id(N'[dbo].[TestTable]') and OBJECTPROPERTY(id, N'IsUserTable')= 1)drop table [dbo].[TestTable]GOCREATE TABLE [dbo].[TestTable] ([TestID] [int] NOT NULL ,[Description] [varchar] (50) COLLATE Latin1_General_CI_AS NULL) ON [PRIMARY]GO

What Is The Best Way To Dynamically Change Server Or Database Name Inside A Sp?

Jun 8, 2006

To be clear:

You have a store procedure and inside you make Updates or Inserts against another Server. But that name can change and I dont want to change it manually in everyplace.

Per example:

SELECT *
FROM Himalaya.DBName.dbo.tblUserGroup
WHERE fldUserID = 7300

I have several Selects, Updates and Inserts pointing to that server.

What I can do if I want to change from Himalaya server to another server?

The same with the Database Name.

Dynamically Specify Server And Database In Stored Procedure

Feb 28, 2007

I am writing Stored Procedures on our SQL 2005 server that will link with data from an external SQL 2000 server. I have the linked server set up properly, and I have the Stored Procedures working properly. My problem is that to get this to work I am hardcoding the server.database names. I need to know how to dynamically specify the server.database so that when I go live I don't have to recompile all of my stored procedures with the production server and database name. Does anyone have any idea how to do this?

EXAMPLE:

SELECT field1, field2 FROM mytable LEFT OUTER JOIN otherserver.otherdatabase.dbo.othertable

OBJECTIVE:

Replace 'otherserver.otherdatabase.dbo.othertable' with some other process (dbo.fnGetTable('dbo.othertable')????)

How To Dynamically Assign Database Name In Query Or Store Procedure?

Sep 22, 2006

Hello,

I am not sure if this possible, but I have store procedures that access to multiple databases, therefore I currently have to hardcode my database name in the queries. The problem start when I move my store procedures into the production, and the database name in production is different. I have to go through all my store procedures and rename the DBname. I am just wonder if there is way that I could define my database name as a global variable and then use that variable as my DB name instead of hardcode them?

something like

Declare @MyDatabaseName varchar(30)

set @MyDatabaseName = "MyDB"

SELECT * from MyDatabaseName.dbo.MyTable

Any suggestion? Please.

Thanks in advance
