C:\Users\lzhlzh>exit /B

while my first if statement works

it sets second_stg_rman_log_trc_prefix lap63-sin_wcdb_20220817_172222_set_scn_scn_number

but my second if statement look like it never really run

it is supposed to set initial_rman_log_trc_prefix="2nd_delcampo"

but it never sets. Instead it is back to "" .an empty string

any insight will be greatly appreciated. many thanks in advance

Looks like the space between "yes" and "(" is missing in the second IF statement. Maybe this causes the problem.

Additional to Steffen's answer:add " to the IF statements.

Code: Select all

if "%lower_prefix_log_with_datetime%"=="yes" (...

Also

/I should be added to the IF.

In this way empty strings cannot cause problems and you see if there are additional spaces that should not be there (or if a space is missing).

I wanted to confirm that if it no possible to do a multiple line if else statement in batch files.

many thanks
