oracle - ERROR java.sql.SQLException: ORA-01722: invalid number while running a Prepared Statement to alter a Sequence -

- 

sqlstmt = new stringbuffer("  alter sequence "  );                       sqlstmt.append( servercontext.getschemaname() );                     sqlstmt.append("seq_edcd_trace_num");                     sqlstmt.append( " increment " );                     sqlstmt.append( " ? " ); pstmt.setlong(1, incval); pstmt.execute();

you can't use bind variables ddl, such alter sequence. you'll have concatenate incval onto string.

there shouldn't risk of sql injection if incval int or long.
