Question

As an input I’ve got a plain SQL query smth like:

select * from (
    select * from Table where id in (1,2,3,4,5,6,642,7,8,9)
        or another_id in (1,2,3,4,5,6, 34 ,7 , 8,9))
where yet_another_id in (1,2)

I want to find all IN clause statements where the amount of arguments passed in is greater than XXX.
So far I’ve came up with this solution.

 ^.*\s*+(?:in)+\s*+(\((?:\s*+\d+\s*+\,?+){XXX,}+\){1}).*$

where XXX is the number of arguments.
Obviously, the first part:

 ^.*

eats all IN clause statements except the last one. How can I fix that? Any suggestions how can I improve the regex?

Answer 1

Try this here

\bin\b\s*(?:\((?:\s*\d+\s*\,?){5,}\))

So I removed some stuff from your expression and fixed an obvious error (\(?: where you escaped the wrong bracket.

The \b is a word boundary.

This is working now for me here on Regexr
