Ah, more than one way to do it... I too think that "from" is the key here because the XYZ.TABLENAME always follows the word "FROM".

SQLstr =~ /[FROM | from]\s(\w+)\./;

OK so... find FROM (in upper or lowere case) followed by one or more spaces \s followed by one or more WORD \w+ characters (i.e. letters) followed by a literal dot \.

Now the parentheses around \w+ actually captures that part of the match in $1, so next you can substitute that piece alone....

SQLstr =~ s/$1/OWNER/e

The "e" causes the $1 to be EVALUATED so that the resulting string is expanded before the substitution....
