SQL Oracle - Replace function in Where Clause

Question

I want to use the REPLACE function in the Where clause to replace a character that I put into a input box. For example if I input R123;R321 I want it to change my input to R123','R321 .

Example of my query:

Select
    order_no

From
    order

Where
    order_no in ('&Order_No') 

I input the data with this box:

Any help would be appreciated, or if there is some other way to do it without the REPLACE function.

Answer 1

That won't work like this, I'm afraid. You'll have to split input value into rows, eg

SQL> select deptno, ename
  2  from emp
  3  where deptno in (select regexp_substr('&&deptnos', '[^;]+', 1, level)
  4                   from dual
  5                   connect by level <= regexp_count('&&deptnos', ';') + 1
  6                  )
  7  order by deptno, ename;
Enter value for deptnos: 10;20

    DEPTNO ENAME
---------- ----------
        10 CLARK
        10 KING
        10 MILLER
        20 ADAMS
        20 FORD
        20 JONES
        20 SCOTT
        20 SMITH

8 rows selected.
