Hi all,

I'm trying to create a trigger function for a few tables that will store
old versions of rows prior to any update on them. Part of the function
needs to creates other tables (the table to store these snapshots in).

When this trigger runs I get the and error of 'syntax error at or near
"$1" at character 15' which is the CREATE TABLE line.


Yes, I don't think support statements like CREATE TABLE currently work with variables directly. You probably can use EXECUTE however by generating a string containing the command you want to run first.

Something like:
EXECUTE ''CREATE TABLE '' || snapshottable || '' (LIKE ''
|| originaltable || '')'';

excepting that you'd need to be more careful with quoting.


Thanks Stephanm, that fixed it.
