I have a store procedure in DB2
CREATE OR REPLACE PROCEDURE INSERT_MSG (
I_MSG_ID INTEGER,
I_MSG_DATA BLOB
)
DYNAMIC RESULT SETS 0
LANGUAGE SQL
BEGIN
INSERT INTO MSG_TABLE(MSG_ID, MSG_DATA)
VALUES (I_MSG_ID, I_MSG_DATA);
END
and xml
<named-stored-procedure-query
name="INSERT_MSG"
procedure-name="INSERT_MSG"
returns-result-set="false"
call-by-index="true">
<parameter
name="I_MSG_ID"
direction="IN"
query-parameter="I_MSG_ID"
type="Integer"
/>
<parameter
name="I_MSG_DATA"
direction="IN"
query-parameter="I_MSG_DATA"
type="byte[]"
/>
</named-stored-procedure-query>
java code:
Query q = em.createNamedQuery("INSERT_MSG");
q.setParameter("I_MSG_ID", msgId);
q.setParameter("I_MSG_DATA", msgData);
q.executeUpdate();
I got the DB2 SQLERROR
Input data type mismatch, see chained exceptions; will retry execution using describe input information.
Please change application to use an input data type that matches the database column type as required by JDBC semantics. ERRORCODE=4461, SQLSTATE=01000:01000 - com.ibm.db2.jcc.b.SqlException: DB2 SQL Error: SQLCODE=-301 ....
Though record can be inserted but how do I resolve this error message, do I need to tell Blob in parameter?
Thanks in advance.
