Simple loop question

[Former Member]

I have an internal table called table1 with data as below:

col1

-

---

123

234

456

I would like to write a an one line condition check like this: (i.e. replace words between brackets with code)

IF (table1 has col1 with the data '234').

" do this code

ENDIF.

I'm not sure which function to use to do this. Do I have to first read the data then check the result count or can I just put it on one line like this?

use

read table table1 with key col1 = 'xxxx'.
if sy-subrc = 0.

endif.

ok, so it looks like I do need two lines. Thanks for your help.

Loop at itb1.
If itab1-col1 = '234'.
Do this.
else.
Do this.
endif.
Endloop.
