After struggling for a day trying to fix the aforementioned error, I couldn't find a way to solve the situation.

To reproduce the problem, just adjust the Usage example:

local fb = require 'fbclient.class' local at = fb.attach('localhost:/my/db.fdb', 'SYSDBA', 'masterkey') local sql = 'insert info foo (id,name) values (?,?) returning id, name' for st, id, name in at:exec(sql, 1, 'John Doe') do --> error print(id, name) end at:close()

I'm using version 0.4 on a MacOS X

Oops. Firebird 2.5 beta 2.

Apparently it is a "problem" with Firebird 2.5 family. They no longer accept isc_dsql_fetch for isc_info_sql_stmt_exec_procedure types. You have to use isc_dsql_execute2 instead.
