Ok, I have a table with several column all labeled, column1, column2, etc. I need to loop through them so I have this statement which will loop through and get the first value, then go to colun2, etc
declare @score int
declare @stm nchar(500)
set @score=0
While @score<=50
Begin
Set @score=@score+1
set @stm='select column' + rtrim(convert(char(2),@score))+' from tablename'
exec sp_executesql @stm
if @score>50
Break
else
COntinue
end
My question is, how can I stuff this value from the dynamic sql into a variable such as:
Hi guys, I have the following store procedure:PROCEDURE dbo.AddSearchColumn (@A1, @A2. @A3, @A4, @A5) ASDeclare @cElements cursor,@DocNum varchar(100)BEGIN Set @cElements = cursor for select FirstNaname rom dbo.DocTable1open @cElements fetch NEXT from @cElements into @DocNumwhile (@@FETCH_STATUS = 0) begin if (@DocNum==@A1 //Here is what I need to do: I want use @A1 at the first loop step, @A2 at the second, and so on....... // @A1, @A2 are the parameters in inputendENDclose @cElementsDEALLOCATE @cElements I hope my explanation is clear.Please, give some hints.Thanks for your time,Christian Malatesti
I have a trigger which retrieves database names from a table. I need to use this retrieved database name in another sql insert statement as a variable e.g. set @mydbname = Select .... from.. (to get the database name) then.. insert into @mydbname.dbo.emplTable
At the moment it reads @mydbname as the string "@mydbname" not the value the variable holds
I need the database name as a variable because i have to write to the correct database (there are 15) Any help appreciated
how to use a Dynamic variable on a function, to explan my self more here is a sample, we use this on SP but the function not allow executing.

I've a roblem with table variables in dynamic sql context.
If i use it with normal sql there is of course no problem. Simplified it looks like this:
-- Standard SQL ---------------------------------------------------------------------------------------------------------------- DECLARE @TestTable as TABLE(MyBigInt bigint NOT NULL, Myint int NOT NULL);
INSERT @TestTable SELECT 4711,10
SELECT* FROM @TestTable -----------------------------------------------------------------------------------------------------------------------------------------
If i do the same thing in dynamic sql, i get errors.
SELECT* FROM @DynamicTestTable; -----------------------------------------------------------------------------------------------------------------------------------------
What is wrong with tis code? Or are table variables not supported inside dynamic SQL?
I have a table with 52 columns named 'Week1', 'Week2' etc. with values 1, 0 etc. I want to check values in each column. I have following lines in my procedure.
Declare @l_str varchar(50), @l_count int
Select @l_count = 1 Select @l_str = 'Week' + Convert(varchar, @l_count) Now how do I compare the value stored in the @l_str which should be wither 0 or 1 and not 'Week1'?
Is there any better method to compare read these 52 table variables?

Hi allIn the SP below im (trying to) do some dynamic sql. As you can see the tableto use is set as a variable and the 'exec' method used to run thesqlstatements.My problem is that the 'if exists' method is not doing what i was hoping itcould do.The @presql command returns somewhere between 0 or 50 rows (give and take) -i just want the 'if exists' part to determine if the select statementreturns something or not since i then will have to update a current row - orinsert a new one.Even if there is no rows returned, the 'if exists' command will return true:-/Any suggestions to a different way of approach...?Thanks in advance :-)######## Stored procedure start ########[various @ variables]....declare @presql varchar(200)select @presql = 'SELECT * FROM '+@CurrentDB+' where btsiteID='+cast(@SiteID as varchar(6))+''IF exists((@presql))BEGINdeclare @UpdateSQL varchar(400)set @UpdateSQL = 'UPDATE '+@CurrentDB+' SET btDate='''+cast(@FileDate asvarchar(12))+''''exec(@UpdateSQL)ENDELSEBEGINdeclare @InsertSQL varchar(2000)select @InsertSQL = 'INSERT INTO ' + @CurrentDB + '(btDate,btTime)VALUES('''+ cast(@FileDate as varchar(12)) + ''','+ cast(@ImportTime as varchar(6)) + ')'EXEC(@InsertSQL)END######## Stored procedure end ########

The last line above is where I am getting the error. Is this possible to do this?
I am trying to use this statement in a variable, including another variable:
"SELECT * FROM my_table WHERE CAST([timestamp] AS INT) > " + @[User::LastTimestamp]
But the variable value insists on giving me this error:
The expression for variable "VariableName" failed evaluation. There was an error in the expression.
I cast the columntype "timestamp" to int, and the variable "LastTimestamp is stored as int32, and has a default value of 0. I simply can't grasp what it is I am missing.
Is it because the expression is part string and part integer? If so, how is that avoided?
Error Output: -------------------------------------------------------------------------- my new db test Server: Msg 911, Level 16, State 1, Line 1 Could not locate entry in sysdatabases for database 'my'.

Any idea how to get the entire database name to be used with spaces in the database name. It prints the @DatabaseName just fine, but in the dynamic sql, it truncates after the first space.
I already tried N'my new db test' in the set statement. That didn't work. I tried using NVARCHAR when declaring the variable.
Ok, so I have this stored procedure that Inserts a record and I need to return the ID inserted to pass to another procedure. I ended up having to use sp_executesql because I need to dynamically add the schema to the table. The issue that I am having is that the variable that I try to pass to the other procedure always ends up null, but it shows the correct output. Just to clarify on this, i am an Applications developer and not a DBA so I may be going about this all wrong. Any help on this would be greatly appreciated.

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
HiI'm grateful for any light you can shed on this!!I've to admit, it's an unusual design but I've multiple contact tables namede.g. i2b_ash_contact or i2b_ted_contact.'i2b_' and '_contact' are static but the middle part is dynamic.Storing all contacts in one table with an identifier of e.g. 'ash' or 'ted'for each record is not possible.Returning the value from the dynamic Query is no problem but I don't knowhow to assign it to a variable.When I try doing this it either runs into problems with evaluating thevariables or doesn't retuen anything at all e.g. if I say at the end 'Print@AddressID'. The variable remains empty.How can I do something like:DECLARE@AddressID int,@ProgClient (varchar(10),@Table varchar(10)Note: @Prog is a string e.g. 'ash' or 'ted'SET @Table = 'i2b_ + @ProgClient + '_contactSET @AddressID = (SELECT AddressID FROM @Table WHERE ContactID = @ContactID)
Is there a way to write such a query where we can declare the variable dynamically ? Currently I am using the query as shown below :
declare @pYear_Internal as NVarchar(100) set @pYear_Internal = [D FISCALPERIOD].[FP CODE].[FP CODE] WITH MEMBER MEASURES.[REVENUE] AS [Measures].[TOTAL REVENUE] SET LAST5YEARS AS STRTOMEMBER(@pYear_Internal).Lag(4) : STRTOMEMBER(@pYear_Internal)
[code]....
While executing the above query, getting the error - Query (1, 9) Parser: The syntax for '@pYear_Internal' is incorrect. Â It looks like it doesn't recognize DECLARE keyword as it does with SQL queries. Â I just want a query that runs directly against the server.Â
I am trying to use the idea as mentioned by Jamie at: http://blogs.conchango.com/jamiethomson/archive/2005/12/09/2480.aspx which is to build dynamic SQL using a variable evaluated as an expression.
Set Expression="SELECT * FROM MyTable WHERE MyColumn = " + @[VariableContainingFilterValue]
Everything works fine. The entire package works. My next step is to log the variable so that I know, after package execution, exactly what SQL statement the package is executing. I tried to do it by a couple of ways in a Script task:
which provides the format as myFileName_yyyymmddhhmmss.xls.
This value is then assigned to a variable, user::myFilenameDateTime.
This variable is referred to in various steps which need the full pathname or filename.
I found, though, that in subsequent steps, the value for user::myFilenameDateTime is re-calculated whenever the variable is invoked.
So in one Task i created the physical output XLS file and named it "correctly", eg, myFileName_20070428090204.xls; in the next Task, i call a Stored Procedure in SQL Server 2005 to email the file with a corresponding message (that pulls in more data from the database).
The single Parameter to the Stored Procedure (that does the emailing) is the supposed/expected full Pathname of the outgoing file just produced but the parameter no longer represents the original filename -- and has changed slightly (a few seconds have been added) and the filename is now, myFileName_20070428090210.xls; consequently, my Email Distribution program cannot find the file with that specific name, although File = myFilename_20070428090204.xls does certainly exist.
so it appears that these variables are calculated realtime whenever encountered.
1) Am I misunderstanding something or misusing the variable assignment?
2) How can i keep << myFileName_yyyymmddhhmmss.xls >>, "static" throughout the duration of the overal SSIS Process.
3) I would think that even if I assign the derived myFileName value initially to ANOTHER "static" variable, this won't achieve anything because the new variable will be re-calculated again, as well, when it is invoked.
I have a dynamic query which returns me a result and I want to capture that value to make further use of it in the same code. Is that possible?? exec ('select col_nm from table_name'). i want the result of this query to be captured. DP
Is there a way to assign a dynamic query result to a local variable?
declre @sqlString nvarchar(4000), @minEventDate datetime, @databaseName varchar(25) selct @databaseName = 'customer_12345' (actually, a cursor loop will assign the database name dynamically, here just to simplify the situation)
Though the select min(eventDate) from customer_12345.dbo.tblABC returns a date, ex. '02/01/2004 12:35 pm', however, the printed @minEventDate is always with Null value. It mean, the value was never correctly assigned to the local variable.
As an alternate way, I am using temp table to insert it with the query result and then assign to the local variable. Since I have many local variables to try to get the min, max, count for around 10 fields, perfer a way to direct assign to the local variable instead of 10 temp tables.
updating a recordset contained in an System.Object variable during runtime.
I am trying to execute multiple file actions (plus parsing those files into a set of staging tables) at separate locations in parallel. I know I can do this in C# but I have a business requirement to use SSIS for all ETL operations.
Any one site can have 0 to many of 1 to 3 files. I would like to run multiple sites at the same time, so when all files of all types are completed at that site then go on to the next site in the list. I know I can do a single site at a time in a foreach loop but if I can run lets say 3-5 sites concurrently then I should be able to save execution time.
My thought is to have a recordset of the sites, when any 1 of the 3 (or more) "control flows" is open, update the recordset to let it know that site being actioned, when that site is complete, update the recordset that the site is completed, and so on.Or am I running in the wrong direction?
I have a dts package that currently uses a dynamic properties task to set the values of global variables. Each variable is based on the value of a query to the database.
I am in the process of migrating this dts package to SSIS but cannot find an equivalent function. I have looked at property expressions but cannot get this working the same way.
Note that in the sp_executesql statement, the @ret variable from the dynamic SQL gets assigned to the local variable @retVal.
Here's the problem; when the procedure [log].[Log.SetSeverityLevel] that gets dynamically executed does a RAISERROR, the code in [dbo].[ProcedureTest] falls through to the catch block in [dbo].[ProcedureTest] as it should, but the value of @retVal is null in the catch block, when the return code in [log].[Log.SetSeverityLevel] is set to -1.
If you comment out BEGIN TRY / END TRY / BEGIN CATCH / END CATCH in [dbo].[ProcedureTest], the value of @retVal is correctly seen as -1. There's something about the TRY CATCH structure that's blowing away @retVal when an error is raised and it falls through to the CATCH block.
Anybody ever seen this before? Is there a workaround?
I am building an SSIS package that loops through a table in SQL Server and dynamically builds a select statement that i would like to use as an ole db source. I have been having a difficult time with this as the select statement that i am generating is over 200,000 characters long so using an sql variable is out of the question.
I ended up placing the select statement into a table where each row of the table represents a piece of the select. I then use an execute_sql task that selects the entire rowset from this table into a variable object. I then use a for each loop to shred the variable and concatenate it into on big string variable called user:: sql_statement that is my select.
After setting up the loop and testing to see if the user:: sql_statement variable populates correctly i then added a data flow transfer with an ole db source and destination. I then go into the advanced editor for the source and set it to accept an sql statement from a variable and use my user:: sql_statement variable. I was forced to set validate external metadata option to false to avoid an error since there is no way to validate the columns until the for each loop runs during run time.
Now thats all fine and good but what is causing my problem is that during run time, when the package gets to the data flow task, the select statement doesn't seem to be populating the input columns of the data source. I have been searching to no avail on a way to tell the data source to update the input columns but every time it gets there, the package bombs out telling me the ole db source has no available output columns.
Specifically the error i get is : [DTS.Pipeline] Error: "output "OLE DB Source Output" (6616)" contains no output columns. An asynchronous output must contain output columns.
