Logic to pull the data without performance issue

Former Member — Mon, 31 Aug 2009 12:28:49 GMT

Hi all,

I am having one ZTABLE

Which contains 50 fields.....

I want ztable data into one internal table with only 2 conditions..I am worring of performance issue any one help me please!!

Requiremetn....

ztable -> data will be pulled into internal table itab on one condition where feild1 = '100'.

now my itab is having 10 records imagine..

where all 10 records with field1 = '100'.

Now i need to check what is the value of Field2 in itab.

the field2 is imagine is as follows 1000 , 2000, 3000 , 4000...

Now check the field2 value in the internal table where the field2 is having only ''100' or any other number if it has any other number then pull that also .....so imagine if field2 '1000' is having 100 & 200 both should be in ITAB.

so how to write the logic with good perfromance ...

Regards

Hi,

Use this query hope this will resolve your issue....

SELECT * FROM ztable INTO TABLE itab
WHERE field2 IN ( SELECT field2 FROM ztable WHERE field1 = '100' ).

If I understand your question correctly, it's pretty basic - just create an index on field2 (non-unique).
