Hi all

(1) What is the performance issue regarding folowing statement select-endselect inside loop.

Loop -

Select -

Endselect.

Endloop.

Is there any option to write this statement in other way.

2) In SAP-script se78 is used to upload logo. Then why we need the std programe

RSTXLDMC WHEN UPLOADING LOGO.

Loop......

Select ....... into (internal table)

endloop.

Regarding SE78 and RSTXLDMC... as far as I know

.TIF file you can upload only using RSTXLDMC program not through se78, it will give you the error.

Hi,

1. If you write the select query inside the loop, for each avery record in the loop it will go to db table and fetches the data, so obviously there will be impact on Database. Instead of that Use select Query ouside the loop and use READ statement inside the loop.

2. They are 2 different ways to upload the logo. SE78 also will internally calls RSTXLDMC Program.

1. Isn't a good idea to do select inside a loop statement. Select all data you need into a internal table and inside the loop use read table statement!
