UNIX alias question

What is the proper syntax to make an alias out of:

expr `(ls -l /vol*/oradata/${ORACLE_SID}/* | awk '{print $5," + "}'; echo 0)`

I tried several ways including:

alias dbsize='expr `(ls -l /vol*/oradata/${ORACLE_SID}/* | awk \'{print $5," + "}\'; echo 0)`'
ksh: 0403-057 Syntax error: `)' is not expected.

I've been staring at this too long...
