Yes, please run attached class. Using metadata it finds those two indexes and fails to drop last one.
Table: RECEIPT Index: SQL080509095407610 Table: RECEIPT Index: SQL080509095407630 java.sql.SQLSyntaxErrorException: ALTER TABLE failed. There is no constraint 'APP.SQL080509095407630' on table '"APP"."RECEIPT"'. If you use method dropUsingSysconstraints(con) instead dropUsingMetadata then everything works.

Not sure what your exact problem is, can you post a standalone repro? I tried the following which worked: st.execute("create table mytab (id int primary key, " + "name varchar(50))"); : s = con.createStatement(); DatabaseMetaData dbm = con.getMetaData(); rs = dbm.getIndexInfo(null, null, "MYTAB", false, false); while (rs.next()) { System.out.println("Table: " + rs.getString(3) + " Index: " + rs.getString(6)); s.executeUpdate("alter table " + rs.getString(3) + " drop constraint " + rs.getString(6)); } Dag _____________________________________________________________________ This e-mail has been scanned for viruses by MessageLabs. ********************************************************************** Confidentiality : This e-mail and any attachments are intended for the addressee only and may be confidential.
