save output of awk into a variable in a shell script

I need to save the output of this command into a variable

$scriptName | awk '{split($0,a,"_"); print a[1]}'

I tried to do this but it didn't work

schema=$( $scriptName | awk '{split($0,a,"_"); print a[1]}' )

can please someone tell me out to do that? thank you.

Third alternative:

$script | awk ' ... ' | read schema

Here's a slightly simpler way:

schema=`echo $scriptName |awk -F_ '{print $1}'`

Try

schema="$( $scriptName | awk '{split($0,a,"_"); print a[1]}' )"

(with quotes). But how do you check if it works or not?
