Thank you for the link. The situation in my case is different. Here is a simplified code for my example where normally I get the auto-increment:
ResultSet rscol = null; Sring autoInc =null; int colAutoInc=0;
Statement stmt = cnx.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY); ResultSet rs = stmt.executeQuery("Select * from " + db_table);
DatabaseMetaData dbmd =cnx.getMetaData(); cnx=Connection for (i = 1; i <=numberOfColumns; i++) { rscol = dbmd.getColumns(tableCatalog, tableSchema, db_table, columnName); while (rscol.next()) { autoInc = rscol.getString(12);returns "auto-increment" if column is in fact auto-increment if (!autoInc.equals("")) colAutoInc=i; } }
