read table

[Former Member]

please explain about read table and sy-tabix clearly

[Former Member]

read table you can also use it to avoid looping inside a looop....

use of read table is as..

loop at i_tab.

read table i_tab2 with key xyz =i_tab-xyz.

-

---

endloop.

what it does it it reads the internal table i_tab2 till the where ocndition is true...

Also more performance tuned than nested loop.

Read table will get the first record that saitisfies the condition specified in the with key statement into the header.

if an itab contains the following data:

field1 field2

1 one

2 two

3 three

4 four

5 five

And if you read the itab like this:

read table itab into WA with key field1 = '3'.

if sy-subrc = 0.

write:/ wa.

endif.

The output will be

3 three.

The sy-tabix will hold the value of index of the current record.

Hi,

Read is used to get the single record into work area from internal table body which matches ur requirement.It is very efficient if we use sy-tabix and binary serach with Read.

read table itab index sy-tabix binary search with key.....

Read table is used to read one record from internal table at a time

READ TABLE ITAB INDEX 1.

the above READ will read the first record in internal table

SY-TABIX is the counter which will increment by 1 on every loop pass..this is used only when looping at internal tables

LOOP AT ITAB.

WRITE : / SY-TABIX.

ENDLOOP.

Hi,

Read table reads the table contents from the specified table with key or index as specified. See Help on read table for details.

If the Read Table succeeds, the sy-tabix returns the index of the record captured.

If you use...

Loop at tab1.

read table tab2.

endloop.

Then, after loop at statement & before read table statement sy-tabix returns the index of tab1. After read table statement, sy-tabix returns the index of tab2.

This is all I guess you are needing.

Reward if it helps.

Hemant.
