Scrutinizer - If it was that easy with grep, why would I waste your time.
the problem really is just not the $ETL_VW_SCHEMA, the way its generated with in the quotes and text coming after that(table name).
i.e as I mentioned, this is how it looks :

FROM '"${ETL_VW_SCHEMA}"'.PROJ
FROM '"${ETL_VW_SCHEMA}"'.PROJ_ABC

FROM '"${ETL_VW_SCHEMA}"'.PROJ_XXX
FROM '"${ETL_VW_SCHEMA}"'.PROJ_YYY
FROM '"${ETL_VW_SCHEMA}"'.PROJ_ZZZ

I just need to extract PROJ(the first line) and I am sure there is a way of doing this if not grep.

ZGREP(1)						    BSD General Commands Manual 						  ZGREP(1)

NAME
zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files SYNOPSIS
zgrep [grep-flags] [--] pattern [files ...] zegrep [grep-flags] [--] pattern [file ...] zfgrep [grep-flags] [--] pattern [file ...] DESCRIPTION
zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1). The grep-flags and pattern arguments are passed on to grep(1). If an -e flag is found in the grep-flags, zgrep will not look for a pattern argument. zegrep calls egrep(1), while zfgrep calls fgrep(1). EXIT STATUS
In case of missing arguments or missing pattern, 1 will be returned, otherwise 0. SEE ALSO
egrep(1), fgrep(1), grep(1), gzip(1), zcat(1) AUTHORS
