Hi,

I have single list of employee ID's and concatenated list of employee ID's stored in two separate tables.
concatenated list not correct at some places as observations but I want to list out such all records where concatenated list different than single list.

Example here concatenated list is incomplete compared to single list. I am not sure to use oracle functions like regexp_like or INSTR in such case. please let me know if any suggestions

Table 1

Dept_ID	Employee_ID
101	415P
101	I999
101	J766
101	K565
101	Y234
	
Table 2
	
Dept_ID	Concat_Employee_ID
101	415P;I999;J766

With any SQL question, Post a working Test case: create table and insert statements along with the result you want with these data then we will be able work with your table and data. Explain with words and sentences the rules that lead to this result.
...
Also always post your Oracle version, with 4 decimals, as solution depends on it.

Here's a example for 11gR2:
SQL> select deptno, listagg(ename,',') within group (order by ename) names
  2  from emp
  3  group by deptno
  4  order by deptno
  5  /
    DEPTNO NAMES
---------- --------------------------------------------------
        10 CLARK,KING,MILLER
        20 ADAMS,FORD,JONES,SCOTT,SMITH
        30 ALLEN,BLAKE,JAMES,MARTIN,TURNER,WARD

And don't forget to feedback to your topics.
