Internal table value checking in custom table using SQL...

Question

I have a table which has following fields:
X1 TABLE (ZCONfig custom table)     
LIFNR  land1                   
123      br                    
234      br                     
456      br                     
567      Gr
and
X2 TABLE: (Internal table)
LIFNR:
234
567
123
Now I want to see if all the field values of LIFNR in internal table X2 (X2-LIFNR) are present in X1 or not.
Raise error if it is not.
How do I do this using SQL ? I guess I have to use read statement.
Please help. Points will be awarded.
Thanks.
Regards

Hi Tushar,
1 Ya u are right , we need to use READ statement.
2. Populate X1 (all records)
   in an internal table.
3. Then Loop at X2
   and compare with X1.
  ( u can also keep an extra field in X2
    of type c, so that if a record is found,
   mark it as X )
4. try this code (just copy paste)
REPORT abc.
DATA : BEGIN OF itab OCCURS 0,
       bukrs LIKE t001-bukrs,
       present TYPE c,
       END OF itab.
DATA : t001 LIKE TABLE OF t001 WITH HEADER LINE.
itab-bukrs = '1000'.
APPEND itab.
itab-bukrs = 'X000'.
APPEND itab.
SELECT * FROM t001 INTO TABLE t001.
LOOP AT itab.
  READ TABLE t001 with key bukrs = itab-bukrs.
  IF sy-subrc = 0.
    itab-present = 'X'.
    MODIFY itab.
  ENDIF.
ENDLOOP.
BREAK-POINT.
