Error description
A positioned update or delete fails with SQL0509N if a cursor is opened against alias and update or delete against base table. The following steps illustrates the -509 scenario. . db2 create table S1.T1 (C1 int, C2 char(10)) db2 insert into S1.T1 values(1,'a') db2 create alias S2.A2 for S1.T1 db2 +c declare CUR1 cursor for select C2 from S2.A2 where C1=1 for update db2 +c open CUR1 db2 +c fetch CUR1 db2 +c update S1.T1 set c2='1' where current of CUR1 . SQL0509N The table specified in the UPDATE or DELETE statement is not the same table specified in the SELECT for the cursor. SQLSTATE=42827 . The same problem can occur using the IBM DB2 Driver for JDBC with updatable ResultSets: . Statement stmt = con.createStatement( ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_UPDATABLE ); ResultSet rs = stmt.executeQuery( "SELECT C2 FROM S2.A2 WHERE C1=1" ); while (rs.next()) { rs.updateString( "C2","1" ); }
