Mapping Of Variables While Passing A Resultset To Foreach
Oct 3, 2006
I have an Execute SQL Task1 that executes an extraction stored proc (say spe). spe returns a rowset that has 25 columns. For each row in the rowset, a load stored proc (say spl) has to be executed (spl is executed using Execute SQL Task2). spl has 25 input parameters that match the 25 columns returned by spe (the column names returned by spe and input parameter names of spl are exactly same). To achieve this, in Execute SQL Task1, I had to specify a variable in the Result Set (say User::resultset). After declaring 25 variables, in the foreach loop editor, I had to specify the Variable Mappings of these 25 variables to the column indices of the rowset returned by spe. After this, in Execute SQL Task 2 I had to specify in the Parameter Mapping the mapping between the 25 variable names and 25 parameter names of spl. You can understand that it is cumbersome to define all these mappings manually, especially when there are a lot of variables involved.
Is there some way of telling SSIS that it has to automatically map the columns returned by spe and the input parameters of spl (given that the column names and parameter names match exactly)? Or is there a totally different and simple way of achieving the above scenario?
One more problem that I am facing :-
In this package we are having a dataflow control which returns a recordset destination which has a column named ID(in the Input/output tab it is showing its datatype as DT_I8).This recordset is passed to a foreach container control through User::ID variable which is defined as Int64.
While running the package we are getting an error like this:
Error: ForEach Variable Mapping number 4 to variable "User::ID" cannot be applied.
Error: The type of the value being assigned to variable "User::ID" differs from the current variable type. Variables may not change type during execution. Variable types are strict, except for variables of type Object.
Actually both are related to mapping. I tried the second issue with just 1 variable as well to make sure there is no mismatch. Still, i face the same.
Can anyone please provide a solution to this ?

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?

I'm just getting started with SSIS and have a couple basic questions. I have a Foreach Loop that iterates over a collection of database names. The collection must include only database names that match a substring. I haven't found a way to filter the SMO Enumerator collection so, instead, I feed the resultset of an Execute SQL Task into the Foreach Variable Enumerator.
Of course this variable (oDBnames) is object type so in Foreach Variable Mapping a string variable (sDBname) is mapped to the only value in the collection (database name). Now sDBname should be available for an Execute SQL Task inside the container. But I keep getting the following errors:
Error: 0xC001F009 at Package: The type of the value being assigned to variable "User::sDBname" differs from the current variable type. Variables may not change type during execution. Variable types are strict, except for variables of type Object.
Error: 0xC001C012 at Foreach Loop Container: ForEach Variable Mapping number 1 to variable "User::sDBname" cannot be applied.
Can someone explain what is going on and how to correct this? I haven't found an answer in BOL or MSDN yet. Thanks.
Another beginner question: The results/messages from a query run in Management Studio are displayed in the results/messages panes. But how would you save and view query output when using the Execute SQL Task? Seems like I should be able to dump Full result set into an object variable and display that, but everything I try raises an error ...

Hi:
I am trying to loop through 4 files in a folder and read the names of those files through the For each loop container task. I have 4 readme files (readme1.txt thru readme4.txt) in a folder called C:SSIS.
I have added a for each Loop container and a script task to my package. In the Variable Mapping page I have named the Variable and configured the index to be 0. The problem is when I execute the package the file name that is read is always readme1.txt. I want all the file names to be read under the folder ( in other words configure the index to be 0 thru 4). How do I configure the index so that it can read all the files?.
The following is the code I have in my script task:
Public Sub Main()
Dim variables As Variables
If Dts.Variables.Contains("FileName") = True Then
Dts.VariableDispenser.LockOneforRead("FileName", variables)
End if
Msgbox ("Retrieved the File " & CStr(variables("FileName").Value))
Dts.TaskResult=Dts.Results.Success
End Sub
When I execute the package with the above code, I always see a message box popping up and saying Retrived File Readme1.txt.
I want the msgbox to pop up and say
Retrieved Readme1.txt
Retrieved Readme2.txt
Retrieved Readme3.txt and so forth...
Any help on achieving this is appreciated.
Thanks

As mentioned in a previous posting, I have an in-line table valued UDF with three input parameters. I can set this up as an OLEDB Datasource SQL Command Text with parameter markers (i.e. "?") and test it successfully in the Generic Query Builder. The parameter markers are correctly associated with the input parameters of the UDF and the parameters can be entered at execution time into a parameters table.
So near and yet so far. When I attempt to map the parameter markers with Package Variables there is an error message saying the the parameter details cannot be retrieved from the function. If the function was in a foriegn (e.g. Oracle) database I might accept this as just one of those things but this is a SQL 2005 database and compatability should be complete. Add to this that the Generic Query Builder has no problem with the same UDF and nor does Reporting Services and I have to assume that this is a bug plain and simple.
The only solution that I have seen suggested is to embed the SQL Command text in a Package Variable and change it at execution time but I regard this as a second rate solution.

Is there a way to set a variable as a substring of the enumerator in a Foreach File Enumerator type? The Variable Mappings tab in the Foreach Loop Editor does not allow you to enter an expression.

Hello
I would like to loop through a folder and then log the folder's content, as in the names of the files, into a database like all the events get logged. Here is what i have done. I put some files into the folder c: emp made a loop through it, set up a variable 'temp' scope is the foreach loop, set the variable raisechangedevent to true. I have also confgigured the loop to put the result of the looping, in the temp variable in the variable mappings tab.
Strangely nothing is recorded into the "execution results" when i test run the package ? Do i need to make a event handler for the onvariablevaluechanged event for the foreach loop container to be able to get the value of the variable logged or is there something other that i'm missing ?

Learning how to use SSIS...
I have a data flow that uses an OLEDB Source Component to read data from a table. The data access mode is SQL Command. The SQL Command is:
select lpartid, iCallNum, sql_uid_stamp
from call where sql_uid_stamp not in (select sql_uid_stamp from import_callcompare)
I wanted to add additional clauses to the where clause.
The problem is that I want to add to this SQL Command the ability to have it use a package variable that at the time of the package execution uses the variable value.
The package variable is called [User::Date_BeginningYesterday]
select lpartid, iCallNum, sql_uid_stamp
from call where sql_uid_stamp not in (select sql_uid_stamp from import_callcompare) and record_modified < [User::Date_BeginningYesterday]
I have looked at various forum message and been through the BOL but seem to missing something to make this work properly.
http://msdn2.microsoft.com/en-us/library/ms139904.aspx
The article, is the closest I have (what I belive) come to finding a solution. I am sure the solution is so easy that it is staring me in the face and I just don't see it. Thank you for your assistance.

I am pretty new to this and hope someone can help and I hope I can explain my problem.
I have a php form
<form action="cpesearch.php">
State: <select name="stname">
<option value ="ALL">all states</option>
<option value ="vic">VIC</option>
<option value ="sa">SA</option>etc etc etc
I am then connecting to my datatbase, assign the variables and doing the SQL query.
if ($dbc = mysql_connect ('localhost','root',''))
{
if (@mysql_select_db('database'))
{
$sname = $_GET['stname'];
$pname = $_GET['prname'];
$sql = 'SELECT * FROM `cpe` WHERE eventdate >= CURDATE() AND state = ''.$sname.'' AND presenter = ''.$pname.'' ORDER BY eventdate ASC';
$r = mysql_query($sql) or die("Query failed".mysql_error($dbc));
while ($row = mysql_fetch_array($r))
{
print "<div id="mainContent"> <p>".$row['state']."</p>".
"<p>".$row['eventdate']."</p>".
"<p>".$row['eventtitle']."</p>".
etc etc etc
So my problem is... I have an events table with presenters and state (and other info). I want to be able to select each presenter and state or all presenters and/or states. Not sure then how to pass the variable into my sql statement if they want to select ALL.

Hi,
I have created a view. However this view needs a specific variable that a user has inputted in Access. The variable I need to pass into the first view is a DocketID..Similar to a StoreID. I then must run the second view, which also depends on the same DocketID. Finally I must run a final query that takes the result from the second view, which takes the results of the first view.
Basically, I want to pass the variable from my VBA application to the SQL statement. I have been reading, and it seems that like in VB I must declare a local variable in a DECLARE statement. Is that right?
How would I pass the variable that can be held in the VBA application ex. DocketId = 220 and pass that 220 to my SQL statement which is running is SQL 7.0. Most of the statement will be running in SQL, not the VBA application.

I am executing:
--------------------------------
DECLARE @x AS int
SET @lcQuery = 'UPDATE ... WHERE .... ' + ' SET @x = @@ROWCOUNT'
EXEC (@lcQuery)
PRINT @x
--------------------------------
@x does NOT return a value, because it is "local" to the lcQuery execution. As a matter of fact, to execute it, I have to write:
SET @lcQuery = 'DECLARE @x AS int ' +
'UPDATE ... WHERE .... ' +
'SET @x = @@ROWCOUNT'
EXEC (@lcQuery)
How can I pass the variable @x to the progam from within EXEC (@lcQuery)?
How does EXEC (@lcQuery) execute? In a different space?
Thank you.

I have an SSIS package. In my control flow I have an Execute SQL Task and a data flow task. In my Execute SQL Task in the SQL Statement I have (select dbo.to_date(getdate()) as process_date) its a direct input with a result set. It gets Getdate as (processed_date) is declared. I have set no parameters, but I have set a Result Set. Also, I have set a global variable in the scope where I passes the date (processed_date)
In my Data Flow, I have an OLE DB data source with the following SQL statement in my SQL Command.
I am trying to pass down the variable as the ? .
It works when I pass it only to: lr.processed_date = ?
But I get an error when I pass it down to the : and ? between cav.begin_date and cav.end_date
SELECT distinct
acc.account_num,
FROM
cust_version_slow cvs
inner join cust_acco_version cav
on cus.cust_id = cav.cust_id
and ? between cav.begin_date and cav.end_date
inner join bia.dbo.acct acc
on cav.acco_id = acc.acco_id
inner join bia.dbo.account_version_slow avs
on acc.account_id = avs.account_id
and ? between avs.begin_date and avs.end_date
inner join bia_org ('02','2,3,4,5,6,7,9,10') boh
on cvs.branch_code = boh.branch_code
inner join accou_version_profit accM4
on acc.acco_id = accM4.acco_id
and ? between accM4.begin_date and accM4.end_date
where
lr.processed_date = ?
I need to pass down the same variable (processed_date) which is ? in all the ? in red
Thanks,

In our project users log in and are assigned a GUID. The GUID is stored as a session variable that is used for filtering what a user sees on a page/report etc.
We have a report in which there are 2 parameters (Drop Downs).
Drop Down 1 lists the Entities a user can see (this is filtered by the GUID that is passed to the backend) and this works fine.
Drop Down 2 lists the products a user can see within Entity (this is filtered by the same GUID and also the selected value from DDL1.)
Here€™s the dilemma, how to we pass 2 variables into DDL2, when one of the variables comes from DDL1, and the other is passed by the URL?

Similar to a previous thread, but not exactly. I have a batch file that takes
two date parameters. I have a SQL script that gets the values I want and assigns
them to variables, but I don`t know how to pass these to the batch.
I`m thinking of something like:
declare @myvar1 datetime, @myvar2 datetime
select @myvar1 = <some date value>
select @myvar2 = <some date value>
exec xp_cmdshell "c:mssqlscriptsMYBATCH.BAT" @myvar1 @myvar2
This just errors out when it reaches the variables in the last line. If I move
the variables inside the quotes, it passes them as literal text strings, not as
the assigned datetime values.
Any ideas? Is this possible?
Thanks,
Robert

If I have declared a variable, such as char variable_name[x], and have assigned it a value, how do I go about passing this value to an SQL query such as:
SELECT * FROM variable_name
where my value replaces variable_name.

Hi everyone,
passing variables (values) from a form (MS Access Project) to a stored procedures in order to select records shouldn't be all that difficult. However after searching for hours and hours in various forums and discussions i'm still nowhere. I really hope someone can give me the missing hint.
OK All I whant to do is select data from the sql server via an access interface. the value entered into the access form by the user (for example the client name) should then be transferred to the stored procedure which will then return all the records of the chosen client.
The simple task of transferring this form value to the stored procedure is driving me crazy. Does anyone have an idea.
Thanx in advance

I'm developing an SSIS package that will theoretically be run in two different ways. One is as a nightly job, called by a SQL job. The second is from a web application. When run as a job, it will be looking for a flat file in a known location. Run from the web, the file name and location are determined at runtime. I've tried to handle this by using a variable to hold the flatfile connection string, and setting the variable value to the known location. Then, when called to the web, I determine the file location/name at runtime, and pass it to the package. I'd assumed that if I pass the value into the package, it would override the variable's value that I'd set, but this doesn't seem to be happening. I realize this could very well be due to a coding error, but I thought I'd check to see if this is even a viable approach to be taking. If a variable's value is set in the package itself, will it be overwritten by a value passed to the package (assuming no stupid mistakes)? Or is this entirely the wrong approach to be taking for what I'm trying to do?

I would like to pass variables to the package before it is executed (e.g. I am calling the bcp utility and I need to pass a password to the command line), so that at runtime a variable is set and then used.
Does anyone has some hints for good approaches? Every idea is welcome.
FYI: I do not use the bulk insert task as I need an errorlog file and the command is buggy with the errorfile option, therefore I chose the bcp approach. My connections are dynamic as far as servername and userid is concerned, but I did not find a solution for the password issue.

We have a package with a package variable.
This variable is of data-type 'DateTime'.
However, when i try to pass the value 'NULL' the package fails... i use the following statement with 'dtexec.exe'
/SET Package.Variables[MyDate].Value;"NULL"
What's the correct syntax for passing null-values? But maybe (because i cannot find anything on this) i should ask if this is even possible...

Hi,
I have created lastUpdatedDate variable on package level. I have run a sql task and store a date in that variable.
now i am trying to pass that variable as parameter to oledb source connection (using command). it seems that we cant pass parameter in any sub query or derived table in query. its only working in outer query as soon as we place ? in WHERE clause of inner query it start throwing an 'Syntax Error' error saying that connection provider might not support that.
any idea ?????
I dont want to use command variables as my query is going to be quite big.
Note : I have tried Sql Server Native and OLEDB provider for sql server and this behaviour is seems to be constant in both.
Thanks,
