Compare two Hash Table

[Former Member]

Hi experts,

I want to compare two hash table. here is the sample code.

TYPES: BEGIN OF company,
"name(20) TYPE c,
uom  TYPE char4,
qty TYPE i,
END OF company.

DATA: comp TYPE company,
comptab TYPE HASHED TABLE OF company
WITH UNIQUE KEY uom,
comptab1 TYPE HASHED TABLE OF company
WITH UNIQUE KEY uom.
comp-uom = 'KG'.comp-qty = 10. COLLECT comp INTO comptab.
comp-uom = 'CT'.comp-qty = 20. COLLECT comp INTO comptab.
comp-uom = 'KG'.comp-qty = 30. COLLECT comp INTO comptab.
comp-uom = 'CT'.comp-qty = 10. COLLECT comp INTO comptab1.
comp-uom = 'KG'.comp-qty = 20. COLLECT comp INTO comptab1.
comp-uom = 'CT'.comp-qty = 10. COLLECT comp INTO comptab1.
comp-uom = 'KG'.comp-qty = 20. COLLECT comp INTO comptab1.

LOOP AT comptab INTO comp.
  WRITE : comp-uom, comp-qty .
  NEW-LINE.
ENDLOOP.

NEW-LINE.
WRITE : 'Second Table'.
NEW-LINE.
LOOP AT comptab1 INTO comp.
  WRITE : comp-uom, comp-qty .
  NEW-LINE.
ENDLOOP.

Here I have two table comptab and comptab1. I want to compare these two table.

Regards,

Kapil.

Hello,

You may want to have a look at the Wiki posting:

Hi,

Do it like this. However this is not a normal use of hashed tables and I think it will have impact on performance.

SORT: comptab, comptab1.
IF comptab1[] = comptab[].
  WRITE 'equal'.
ELSE.
  WRITE 'not equal'.
ENDIF.

I think this gives wrong answer since there is no indexing in hashed tables
