DB2 query error during the retrieval of a CLOB field

Question

From Java I am doing the following query on DB2:

SELECT * FROM PRV_PRE_ACTIVATION WHERE TRANSACTION_ID = ?

The field TRANSACTION_ID

Answer 1

Try changing to a specified list of columns in the select list -- my guess is you have a user defined column type (or some other type) which is not supported by your driver. For example, does the statement

SELECT TRANSACTION_ID FROM PRV_PRE_ACTIVATION WHERE TRANSACTION_ID = ?

work? If so then start adding columns in and you will find the problem column.
