bash - AWK variable issue

The variable in awk does not return the result.

I am trying to get the next line of the matched value from file by using awk. It works fine without the variable. Thanks.

$ cat file
name=bobk
snm=sahh
emp=bklc
jdate=879
$
$ awk '/name/{getline; print}' file
snm=sahh   ---------> Got the result
$
$ export MYVAR=name
$
$ echo $MYVAR
name
$
$  awk -v AVAR=${MYVAR} '/AVAR/{getline; print}' file
$   ---------> No result

You need to use the regexp match operator ~ against the whole line $0 as /AVAR/ is match for the string AVAR not the variable AVAR:

$ awk -v AVAR=${MYVAR} '$0~AVAR{getline; print}' file
snm=sahh
