This is for you example:

SELECT* FROM TMP;         ID CD AMT
---------- -------- ----------

         1 AB12             10
         2 KCST            100
         3 123454          150
         4 12TUF24         450
         5 1Q9KJ0          500
         6 EQE786         1200
         7 o0o0o0          675
         8 AA11BB22        950
         9 WY09             50
        10 25OP            775

10 rows selected.

From SELECT statement I want to get the following output:

SELECT * FROM TMP WHERE ...         ID CD AMT
---------- -------- ----------

         1 AB12             10
         8 AA11BB22        950
         9 WY09             50
       

3 rows selected.
