I have the following piece of text in a file : 

thisquery=select \
    table1.column1, \
    table1.column2, \
    table1.column3 alternate_title, \
    table1.column4 \
    from \
    table1 \
    where \

and I need to replace table1.column3 with some dummy id. I'm trying the following one-liner without any success. Any ideas ? If I slurp the file into a single-line string it works, but in multi-line mode it doesn't replace the desired string. What am I missing here ? Isn't the /s modifier supposed to do the matching across newlines ? 
perl -pi -e 's/select(.*?)table1\.column3(.*?)from/select\1DUMMY_ID\2f
+rom/sg' select.sql
