ISSUE:       5813
TITLE:       Wrong syntax with CREATE TRIGGER ... ON <table> used with POSITION
DESCRIPTION:
  Test checks that:
  1. Triggers with POSITION can be accepted only when this clause is at the END of declaration
     (but before SQL SECURITY clause because it belongs to '<routine body>' rather than to the trigger header.
  2. Any kind of trigger which has POSITION not in the end of header section will not compile.
     Failed DDL statement, gdscode and SQLSTATE are written into special table, DDL_AUDIT (in autonomous Tx, of course).

  Finally, we make output of triggers list which present in the database (i.e. which passed) and list of failed DDLs
  from the table DDL_AUDIT, with filtering out any details of their declarations (we need only trigger names from failed DDL).

  ::: NB ::: Section 'expected_stdout' was changed.
  Trigger 'trg_test_bi_sql2003_02' violates SQL:2003 but such form is maintained for backward compatibility.
  This trigger is compiled successfully since build 4.0.0.1767.
