Hi

Is it possible to read where clause from TXT file.

http://www.orafaq.com/forum/m/544066/?srch=external+query#msg_544066

I got guidence form the above link but my query is giving error

select *
from emp
where empno in (@empno.txt)


where emp.txt contains empno 7369 and 7499 in different lines.

The error is
where empno in (@empno.txt)
                *
ERROR at line 3:
ORA-00936: missing expression


Any further thoughts?

[EDITED by LF: fixed topic title typo; was "cluase"]

The topic you mentioned explain in details how to do it: the @file must be on a separate line.
SQL> select *
  2  from emp
  3  where empno in (@empno.txt)
  4  /
where empno in (@empno.txt)
                *
ERROR at line 3:
ORA-00936: missing expression


SQL> select *
  2  from emp
  3  where empno in (
  4  @empno.txt
  5  )
  6  /
     EMPNO ENAME      JOB              MGR HIREDATE           SAL       COMM     DEPTNO
---------- ---------- --------- ---------- ----------- ---------- ---------- ----------
      7369 SMITH      CLERK           7902 17-DEC-1980        800                    20
      7499 ALLEN      SALESMAN        7698 20-FEB-1981       1600        300         30

I suspect the file is not in your SQLPATH.

SQL> get empno.txt

2* 7499


The simple get command is showing values.

Doesn't this mean that my SQLPATH is set?

DO i have to check regedit in order to see SQLPATH?

Thank you so much for your precious time.

I did it.

My learning points are
1) @ command MUST BE ON SEPARATE LINE in SQL command
2) There SHOULD be space between "@" and "empno.txt"
3) The direct command is not working, i have to save it in some file e.g. save abc and then later on the query was running by @abc
4) The values in empno.txt must have comma between them (as it will be placed as it is in brackets of where clause)
5) Path do matters.

Thanks

I don't know Reports but I can move the topic to this forum.

As far as I know, Reports can't do it that way. Use a workaround Barbara described in the same discussion (you posted a link in your first message here) - an external table. Query would then evaluate to
select *
from emp
where empno in
(select empno from abc_as_external_table);
