SYMPTOMS
While using the Microsoft Host Integration Server OLE DB provider for DB2, if you insert on an empty string into a column that is non-nullable, you may receive the following error message:

A SQL error has occurred. Please consult the documentation for your specific DB2 version for a description of the associated Native Error and SQL State. SQLSTATE: 23502, SQLCODE: -407

The SQLState and code indicates the following:

Cause: The column is a target column in an UPDATE, INSERT, or ALTER TABLE statement. If this is an ALTER TABLE statement, a null value exists in a relative entry of the column for which you are attempting to disallow nulls. Otherwise, a null value was specified to be inserted or updated into this column, but the column does not allow null values. If this is an INSERT statement, then the null value was specified in a relative entry in the VALUES list or the select list. If this is an UPDATE statement, then the null value was specified in a relative entry in the SET clause. The null value was specified as either NULL, a host variable with an associated indicator variable that contains a negative value, a column containing a null value, or an expression that evaluated to NULL.

Recovery: If this is an ALTER TABLE statement, change the existing null values in the column to a non-null value. If this is an INSERT or UPDATE statement, change the value so the result is not null. If a host variable is specified, change the value in the related indicator variable to be greater than or equal to zero. Try the request again. The SQLCODE is -407 and the associated message is SQL0407.



CAUSE
The Microsoft Host Integration Server OLE DB provider for DB2 was incorrectly interpreting an empty string as a NULL.
