问题描述

如何获取查询中错误的位置?

How can I get position of an error in the query?

我需要在导致错误的查询字符串中获取位置，就像sqlplus那样:

I need to get position in a query string which causes an error, like sqlplus does it:

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)

我该怎么做?

推荐答案

经过一段漫长的旅行，当我差点失去希望时，我发现了以下链接(感谢Google中正确的搜索字符串):

After some ramblings when I almost lost hope, I found (thanks to correct search string in Google) following link: 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
*
ERROR at line 1:
ORA-00923: FROM keyword not found where expected
ORA-06512: at line 11
