FIX: The DELETE statement does not delete the matching rows in the IBM DB2 table when an SSIS package uses Microsoft OLE DB Provider for DB2

Consider the following scenario:

• A Microsoft SQL Server 2005 Integration Services (SSIS) package uses Microsoft OLE DB Provider for DB2 to connect to an IBM DB2 database.
• A DELETE statement is part of the SSIS package.
• The DELETE statement contains a parameter that is defined as the CHAR data type.

In this scenario, the DELETE statement does not delete the matching rows in the IBM DB2 table when you run the DELETE statement.

For example, the following DELETE statement does not delete the matching rows in the IBM DB2 table when this statement is part of the SSIS package.Notes

• In this statement, the COLUMN_1 parameter is defined as an INTEGER data type. The COLUMN_2 parameter is defined as a CHAR data type.
• A DELETE statement successfully deletes the matching rows in the IBM DB2 table if the WHERE clause does not contain any parameters that are defined as the CHAR data type.
• When this problem occurs, you do not receive an error message. The only result is that the expected rows of data are not deleted from the IBM DB2 table.

The SSIS command transformation process does not bind the length of parameters that are defined as the CHAR data type. Instead, SSIS expects the data provider to derive the length of these parameters. However, OLE DB Provider for DB2 does not derive the length of these parameters. When these parameters are passed to IBM DB2, these parameters have NULL values. Therefore, no matching rows are identified when IBM DB2 processes the DELETE statement.
