Good morning,
I have a function argument blah of type text containing something like
33,44,55,66
. Can I cast it in some way to use it in an IN clause as integers like
UPDATE foo SET x = y WHERE id IN ( blah );
or need I revert to dynamic SQL (EXECUTE...) ?
Thanks, Axel

Hey Axel,
How about this solution:
UPDATE foo SET x = y WHERE ANY(string_to_array(blah, ',')) = id;
?

Ooops, sorry
UPDATE foo SET x = y WHERE id = ANY(string_to_array(blah, ',')::integer[]);

Here is what I think
Hi,
You can do this:
UPDATE foo SET x = y WHERE id = ANY(string_to_array(blah, ',')::integer[]);
Note that you need to cast string_to_array(...) to array type of your id type.

Thanks Richard and Sergey,
your solution works perfect, even if blah contains only one member.
