How to binary search ITAB without structure

Former Member — Tue, 20 May 2014 05:49:39 GMT

Hi everybody,

I defined an ITAB with

lt_rlm_pods TYPE TABLE OF int_ui.

where int_ui is a data-element not a structure!

So, the following is not possible:

READ TABLE lt_rlm_pods WITH KEY int_ui = ls_anlage-int_ui

BINARY SEARCH

TRANSPORTING NO FIELDS.

Does anbody know how to performe the binary search?

Thanks

Regards

Mario

Hi Mario,

Try this:

TYPES: BEGIN OF ty_int_ui,

int_ui TYPE int_ui,

END OF ty_int_ui.

DATA: lt_rlm_pods TYPE TABLE OF ty_int_ui.

READ TABLE lt_rlm_pods WITH KEY int_ui = ls_anlage-int_ui

BINARY SEARCH

TRANSPORTING NO FIELDS.

Viswa.

Hi Viswa,

yes, I tried this already. But I wanted to know, how it works with:

lt_rlm_pods TYPE TABLE OF int_ui.

🙂

Try to check the structure of the Table created in Debug mode. You might understand.

Use pseudo component TABLE_LINE in the READ TABLE statement (press F1 or google help.sap.com)

Hi Mario,

for key access WITH KEY you need one or several fields, and for BINARY SEARCH the table must be sorted by this field(s). Without fields you can't use this READ TABLE itab WITH KEY option.

As it is not possible I mark the question as answered.

Wrong, did you try my solution ?

REPORT ztableline.
 DATA: itab TYPE TABLE OF i.
 APPEND 1 TO itab.
 APPEND 10 TO itab.
 APPEND 2 TO itab.
 SORT itab.
 READ TABLE itab TRANSPORTING NO FIELDS WITH KEY table_line = 2 BINARY SEARCH.
 WRITE: / '2', sy-subrc.
 READ TABLE itab TRANSPORTING NO FIELDS WITH KEY table_line = 3 BINARY SEARCH.
 WRITE: / '3', sy-subrc.

Regards,

Raymond

The READ statement is possible on your Table. But if you check it in debug mode you will see that the structure of your table is as follows

LINE | TABLE_LINE |

Hence the WITH KEY condition in your READ statement must be on the column TABLE_LINE.

Hi Mario,

Raimond wants you to have a look at this:

http://help.sap.com/saphelp_nw70/helpdata/en/fc/eb35f8358411d1829f0000e829fbfe/content.htm

There the option

READ TABLE itab WITH TABLE KEY table_line = f result.

might be of interest.

Sorry, Regards
