Loop By Passing Variable Into Query
Nov 2, 2007
Hi all,
I'm have created a data flow that uses an OLEDB source with a SQL Query. In the WHERE statement of this query is a condition for the storecode. I want to figure out how to create a loop that will cycle through a list of storecodes using a variable which is passed to the dataflow in turn to the OLEDB source's query and runs through the process for each store.
The reason i'm using a loop is because there are about 15 million records that are merge joined with 15 million others which is causing a huge performance problem. I'm hoping that by looping the process with one store at a time it should be faster. Any ideas would be greatly appreciated.

I have a SQL Task that updates running totals on a record inserted using a Data Flow Task. The package runs without error, but the actual row does not calculate the running totals. I suspect that the inserted record is not committed until the package completes and the SQL Task is seeing the previous record as the current. Here is the code in the SQL Task:
DECLARE @DV INT;
SET @DV = (SELECT MAX(DateValue) FROM tblTG);
DECLARE @PV INT;
SET @PV = @DV - 1;
I've not been successful in passing a SSIS global variable to a declared parameter, but is it possible to do this:
DECLARE @DV INT;
SET @DV = ?;
DECLARE @PV INT;
SET @PV = @DV - 1;
I have almost 50 references to these parameters in the query so a substitution would be helpful.

Good morning all,
I have a report which is getting its parameters from an ASP.net page. My ASP developer wants to send in simple values, such as the list 1,2,3,4 for a parameter. However my report needs that list to look like [CD RSRC].[RSRC].&[1], [CD RSRC].[RSRC].&[2], [CD RSRC].[RSRC].&[3], [CD RSRC].[RSRC].&[4].
Is there any way, on the report services side, to capture an incoming report parameter, parse it, loop over the parsed values and format them?
I don't think there is, but I wanted to check before I go back to the developer and tell him he has to send in tuple lists.
Thanks,
Kathryn

Hi everyone I am new to this site I have a major issue I cant figure out seeing how im fairly new to asp, and vb, but i have 5 years php mysql experience.
Im pulling the correct data into a grid. Then i need to make a button or some sort of link that will take the value of one field in the record set and replace it with @transid in the where statement I can enter in the value of transid into form field with that name and it will run the rest of the script correctly, I just cant get past this hurdle. If anyone can help that would be great. I tried to get this to work with java script but then realized thats not possible to transfer varaibles to asp from it.
///javascript
function DisplayReciept(transactionnum)
{
recieptdis = transactionnum;
}
////field in grid
<asp:BoundField htmlEncode=false DataFormatString="<a href=javascript:DisplayReciept{0}>Display</a>" DataField="transid" HeaderText="Show Reciept" SortExpression="transid" />
//////////////query//////////////
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:dbsgcConnectionString %>"
SelectCommand="SELECT [fulldata] FROM [data] WHERE ([transid] = @transid)">
<SelectParameters>
<asp:FormParameter FormField="transid" Name="transid" Type="Int32" />

I am using a sql task to get all tablenames and then passing the output to another sql task inside a for each container.
So that the 2nd sql task will be executed for each table. My query looks like SELECT DISTINCT b.EmailAddress FROMÂ ? ......
Since I am passing the tablename as a variable (output from the 1st sql task), I get the following error:
[Task Execute SQL] Error:
Failed to execute the query 'SELECT DISTINCT b.EmailAddress FROM? AS a INNER... ':' Failed to extract
the result in a variable of type (DBTYPE_I4)'. Possible causes include the following: Problems with the query, not properly fixed ResultSet property, not properly set parameters or not properly established connection.

Hello,
I responded to a very old discussion thread & afraid I buried it too deep.
I have studied the article: How to Pass a Variable to a Linked Query (http://support.microsoft.com/default.aspx?scid=kb;en-us;q314520)
but I have not gotten all the ''''' + @variable syntax right.
Here is my raw openrowset with what I am aiming at.
Code Snippet
-- I want to use some kind of variable, like this to use in the file:
DECLARE @FIL VARCHAR(65)
SET @FIL = 'C:company foldersDocumentationINVENTORY.xls;'
--
SELECT FROM OPENROWSET('MSDASQL', 'Driver=Microsoft Excel Driver (*.xls);DBQ=C:company foldersDocumentationINVENTORY.xls;', 'SELECT * FROM [Inventory$]')
AS DT
Anyone game? Many thank-yous, in advance.
Kind Regards,
Claudia.

Is it possible to assign multiple columns from a SQL query to one variable. In the below query I have different variable (email, fname, month_last_taken) from same query being assigned to different columns, can i pass all columns to one variable only and then extract that column out of that variable later? This way I just need to write the query once in the complete block.
DECLARE @email varchar(500)
,@intFlag INT
,@INTFLAGMAX int
,@TABLE_NAME VARCHAR(100)

I've encountered a new problem with an SSIS Pkg where I have a seq. of Execute SQL tasks. My question are:
1) In the First Execute SQL Task, I want to store a single row result of @@identity type into a User Variable User::LoadID of What type. ( I tried using DBNull Type or Object type which works, not with any other type, it but I can't proceed to step 2 )
2) Now I want to use this User::LoadID as input parameter of What type for the next task (I tried using Numeric, Long, DB_Numeric, Decimal, Double none of there work).
Please give me solutions for the above two..

Hi All!
I have a parent package that contains two children... The second child depends on the succes of the first child.
THe first child generates a variable value and stores it in an Environment variable ( Visibility - All ) ...After the first succeeds, the second will start executing and will pick up the variable value from environment variable( through package configuration setting )...
Unfortunately, this doesn't work...As the second child picks the stale value of the environment variables...Essentially it assigns variable value not after the first child is finished, but right at the beginning of parent execution...
I tried to execute coth children as Out Of Proc as well as In Proc...The same
Would anybody have an idea how to resolve this problem?
Thanks in advance for any help!

I am having a challenge to pass the filename variable from SSIS Foreach Loop Container to SQL store procedure. I have an "Execute SQL Task" inside "Foreach Loop Container" which will receive the input filename parameter passed by the Foreach Loop Container. The store procedure command line is defined as "EXEC sp_mySQLStoreProcedure ?" within the "Execute SQL Task". The Foreach loop container will gather the filenames from File System then put it in the filename variable one by one. I would like to pass the filename variable as the input parameter to the sp_mySQLStoreProcedure in the "Execute SQL Task". How can I connect the variable and the store procedure so that it will process all the input files gathered by the Foreach Loop Container?

The For Loop will execute a stored procedure that passes a variable each time it loops. I need to set this variable, @FiscalWeek, equal to the variable @Counter. So the first time it loops, the counter will be 1, and the Fiscal Year would be set to 1. The next time it would be two, and so forth. Can I do this in the Expressions section of the For Loop? If so,
what would the property be?
InitExpression @Counter =0
EvalExpression @Counter == @CurFiscalWeek
AssignExpression @Counter = @Counter + 1

Hi,
This is pretty simple but I am doing somethin really stupid somewhere, I am trying to pass a value to a variable declared in a package using some SQL code, I declared a variable "var1" and assigned the scope to the package , then I dropped a execute SQL task within the package and wrote a simple sql code that would get the maximum id from a table, "select max(id) from table" , now I want to assign the variable this max value.so in the parameter mapping tab I select the variable give it a parameter name of 0 and size of -1 along with direction of "output". everythin looks simple but when I try to use this variable value in my next execute sql task it behaves weirdly, I am trying to update anothet table using this variable value, so I add another task and put this code in there " update table2 set id = ? " , and on the parameter mapping tab I set the direction as input, however when I look at the column it updated th column with a weird number , xomethin like "230072408" which doesnt mean anything. I know that tha max value of ID is 10.
Please help.
Thanks

Dear All,
I’m trying to collect values from a query into a single variable within a loop, like so:
WHILE condition is true
BEGIN
SET @intLoop = @intLoop + 1
@myString = @myString + ‘, ‘ + (SELECT companyName FROM @tblTheseComp WHERE id = @intLoop
END
For some reason though the @myString does not collect up the values, but will equal NULL at the end of the loop.
If however I simple do
WHILE condition is true
BEGIN
SET @intLoop = @intLoop + 1
@myString = (SELECT companyName FROM @tblTheseComp WHERE id = @intLoop
END
Then I get the last value from the query as expected.
Can anyone explain why this might be?
Thanks in advance!

I am reviewing some code we have inherited (riddled with multiple nested cursors) and in the process of re-writing some of the code. I came across this and it has me puzzled.
As I understand it, if you declare a variable and then try to re-declare a variable of the same name an error is generated. If I do this inside a While loop this does not seem to be the case. What ever is assigned is kept and just added to (in the case of a table variable)
I understand things are in scope for the batch currently running but I would expect an error to return (example 1 and 2)
--Table var declaration in loop
SET NOCOUNT ON
DECLARE @looper INT = 0
WHILE @looper <= 10
BEGIN
DECLARE @ATable TABLE ( somenumber INT )

Hi All,
Seems like a simple task, but been a struggle.
Simply trying to move a group of files from one folder to another folder and renaming the files with the monthyear in the middle of the filename..
I'm using a FOR Loop container and works find. The added complexity is I'm trying to rename the files the same tine and putting the Month Year into the file name.
I guess the struggle is how to get the file name out so I can manipulate it.
I tried creating variable(V_SOURCE) which stores the file path and create another variable(V_FILENAME) to hold the filename. I believe on the expression page of the FOR LOOP editor if I select the the file name and extension radio button, it should put the file name in the V_FILENAME variable.
In my file task trying to join the two variables together in another variable, keep saying my path is wrong with the file task kicks off.
here's the syntaxt
@[User::V_SourcePath] + @[User::V_FILE_NAME]

i need to pass a variable to retrieve data based on user requirements.
i tried this way,

hi guys what is the syntax for using the passing variable part into the name of a table in a store procedure. in particular: (assume already declared the variable periodseq.
select *
into Temp_Usage_@periodseq
from Master_usage
where Master_usage.PERIODSEQ = @periodseq
in particular the Temp_Usage_@periodseq line of code, how do i "add" the periodseq (which is a number) to the end of the name of Temp_Usage, i.e: Temp_Usage_112
is the syntax an & like Temp_Usage_&@periodseq?
Cheers

I've been coding a few years and SSIS makes me feel more stupid than any program I've ever used.
I've read BOL and bought a book. Can't say either one has really helped.
I'm still a complete idiot after one week of working with it. I apologize for asking so many stupid questions.
What I'm trying to do now is parameterize a SQL statement.
I have a variable that's a string. I have a DataFlowComponent as a data source. I find references all over the Internet and this forum to something called an "ExecuteSQLTask" but I sure can't figure out what that is. In my toolbox I have data flow sources for DataReader, Excel, Flat Files, Old DB, Raw file, and XML but no Execute Sql Task.
Anyway SELECT * FROM TABLE WHERE COLUMN='Value' in the SQL Command property is simple enough. Now I want 'Value' to be a variable. You know, like in T/SQL DECLARE @Foo VarChar(25). Creating the variable is easy as pie.
I have found at least 10 different examples of specifying variables on the web, all of which claim to be SSIS examples, Is it User::Variable? @[User::Variable]? @Variable?
I want to read rows from a table, with a a variable value in the WHERE clause, and pass them to the fuzzy lookup task.
Is my approach fundamentally flawed in some way?

My code works fine except the value of the variable @ID is only giving me the first record in the set. How do I pass it on to the next record? I get the right number of rows inserted into the email table but the @ID variable is the same for all 3.
Drop Table #SER1
Select id#,

Hello,
I can't figure out how to pass values from report parameters to a variable in custom code.
I have a Report Parameter called Parm1 of type string. It contains the following:
Label: Value:
Labell1 Value1
Label2 Value2
In custom code I have declared a variable thus:
Public Dim ParmValue As string = Parameters!Parm1.Value
What I want is this: When a user select a report, they will have to choose a parameter from a dropdown-list (created automatically when creating a paramete). The chosen parameter will be passed to the variable ParmValue which I use as one of the parametes in a text-box like this:
=code.InstanceName.MethodName(ParmValue)
InstanceName is the instance of a class from a dll I reference.
It works fine if I hard-code the paramter like this:
Public Dim ParmValue As string = "SomeString" instead of:
Public Dim ParmValue As string = Parameters!Parm1.Value
The error I get is this:
[rsCompilerErrorInCode] There is an error on line 0 of custom code: [BC30469] Reference to a non-shared member requires an object reference.
I don't know if I'm at all on the right track here.
Can someone tell me what I'm doing wrong?
Thanks

Hi:
I'm not an expert with using batch files, or using them with SSIS, but I am trying to use two batch files in my SSIS package. I want the first one to map the first available drive on the server and pass that drive letter as an output variable to the package, and then to pass this variable to the last batch file and unmap.
I already have execute program tasks set up with a hardcoded drive letter, but that is not going to work as I don't know what drive letters will be mapped on this machine.
I did find sample code for using variables in a batch file that maps drives:
Code Snippet
@ECHO OFF
rem Map \serverfolder to the next available drive letter and save
the driveletter as DRIVELETTER

Questions:
1. Is this the type of code I want to use with the SSIS package?
2. How do I use the batch file with SSIS? I see the Execute Process Tasks has a "StandardInputVariable" and "StandardOutputVariable". Will these work?
Thanks,
Kayda

In a stored procedure that I'm fixing, there is a problem with assigning variable values inside a loop. The proc is using dynamic SQL and if statements to build all these statements, but I'm having to add a new variable value to it that is throwing it out of whack.
This is the current structure:
SET @MktNbr = 10
WHILE @MktNbr < 90
BEGIN
DECLARE@sqlstmt varchar(1000)
SET @Market = '0' + CONVERT(char(2),@MktNbr)
SET @sqlstmt = 'SELECT (columns)
INTO dbo.table' + @Market + '
FROM #table
WHERE marketcode = ''' + @Market + '''
IF @MktNbr = 50
BEGIN
SET @MktNbr = 51
END
ELSE
IF @MktNbr = 51
BEGIN
SET @MktNbr = 52
END
ELSE
IF @MktNbr = 52
BEGIN
SET @MktNbr = 55
END
ELSE
IF @MktNbr = 55
BEGIN
SET @MktNbr = 60
END
ELSE
BEGIN
SET @MktNbr = @MktNbr + 10
END
EXEC (@sqlstmt)
END
I'm probably having a blonde moment, but I'm trying to replace the if statements with this:
SET @MktNbr =
CASE
WHEN @MktNbr = 10 THEN 20
WHEN @MktNbr = 20 THEN 30
WHEN @MktNbr = 30 THEN 40
WHEN @MktNbr = 40 THEN 50
WHEN @MktNbr = 50 THEN 51
WHEN @MktNbr = 51 THEN 52
WHEN @MktNbr = 52 THEN 55
WHEN @MktNbr = 55 THEN 60
WHEN @MktNbr = 60 THEN 70
WHEN @MktNbr = 70 THEN 80
WHEN @MktNbr = 80 THEN 81
ELSE @MktNbr END
Clearly it's wrong because the proc bombs every time with a duplicate table error.
It has been suggested to me that I should hold these market values in an external table. This sounds reasonable but I'm ashamed to admit that I don't know how I'd implement that. Can someone maybe give me a nudge in the right direction?
