Output Column Has A Precision That Is Not Valid (loading From Oracle Using OraOLEDB.Oracle.1)

Hi!



I'm loading from Oracle using the OraOLEDB.Oracle.1 provider since I need unicode support and I get the following error:



TITLE: Microsoft Visual Studio
------------------------------

Error at myTask [DTS.Pipeline]: The "output column "myColumn" (9134)" has a precision that is not valid. The precision must be between 1 and 38.



------------------------------
ADDITIONAL INFORMATION:

Exception from HRESULT: 0xC0204018 (Microsoft.SqlServer.DTSPipelineWrap)

------------------------------
BUTTONS:

OK
------------------------------
For most of my queries to Oracle I can cast the columns to get rid of the error (CAST x AS DECIMAL(10) etc), but this does not work for:



1) Union

I have a select like "SELECT NVL(myColumn, 0) .... FROM myTable UNION SELECT 0 AS myColumn, .... FROM DUAL"

Even if I cast the columns in both selects (SELECT CAST(NVL(myColumn, 0) AS DECIMAL(10, 0) .... UNION SELECT CAST(0 AS DECIMAL(10, 0)) AS myColumn, .... FROM DUAL) I still get the error above.



2) SQL command from variable

The select basically looks like this:

"SELECT Column1, Column2, ... FROM myTable WHERE Updated BETWEEN User::LastLoad AND User::CurrentLoad"

Again, even if I cast all columns (like in the union), I still get the same error.



Any help would be greatly appreciated. Thanks!
