如何获得Oracle SQL查询中错误的位置？

Question

如何获取查询中错误的位置？

我需要在导致错误的查询字符串中获取位置，就像sqlplus这样：

SQL> insert into tbl (data) values('12345')
  2  /
insert into tbl (data) values('12345')
                 *
ERROR at line 1:
ORA-12899: value too large for column "schmnm"."tbl"."data" (actual: 5,
maximum: 3)

我怎样才能做到这一点？

当我几乎失去希望时，经过一番漫谈之后，我找到了（感谢 Google 中正确的搜索字符串）以下链接：https : //forums.oracle.com/thread/1000551

SQL> DECLARE
  2     c   INTEGER := DBMS_SQL.open_cursor ();
  3  BEGIN
  4     DBMS_SQL.parse (c, 'select * form dual', DBMS_SQL.native);
  5
  6     DBMS_SQL.close_cursor (c);
  7  EXCEPTION
  8     WHEN OTHERS THEN
  9        DBMS_OUTPUT.put_line ('Last Error: ' || DBMS_SQL.LAST_ERROR_POSITION ());
 10        DBMS_SQL.close_cursor (c);
 11        RAISE;
 12  END;
 13  /
Last Error: 9
DECLARE
