Numeric Datatype To Ssis Variable Datatype Conversion Problem

Good afternoon,

I have an issue with an ssis variable datatype.

The scenario is as follows:

I have a stored procedure:


PROCEDURE [dbo].[sp_newTransaction]



@sourceSystem varchar(50),

@txOut NUMERIC(18,0) OUTPUT

AS

insert into scn_transaction (sourceSystemName) values(@sourceSystem);

SELECT @txOut = @@identity


Whose purpose is to perform an insert into a table and return me the identity value of the inserted record, which I'll then use throughout the rest of my package. The identity column in the inserted table is numeric(18,0).

I execute the stored proc with the following sql with an OLE DB connection manager:

exec sp_newTransaction ?, ?

The first parameter is a string variable from earlier in the package, and the second is the output parameter. I have the following parameter mappings to the execute sql task:

User:ystxId output numeric 1 -1
User:ourceSys input varchar 0 -1

The proc is correctly called, and the row insesrted, however I get a type conversion error when SSIS attempts to map the return parameter to my package variable... I've tried all sorts of combonations, and can't seem to get it to execute.

At one point I wasn't returning a numeric, but rather an int from the stored proc, and all was well until I went to use the variable in a derived column later in the package, and the type was converted quite incorrectly (a 1 was 77799789080 or some such), indicating a type conversion error likely related to the encoding of the number.

I'd like to keep the datatypes as numeric and make ssis use those - any pointers are greatly appreciated as to what type my package variable should be to allow proper assignment of a sql server numeric type to it.

Thanks much,

B
