[Freeswitch-users] Lua freeswitch.Dbh() question

[Steven Ayre]

Currently the answer is no.

It is possible with a patch though. If you look at
src/mod/languages/mod_lua/freeswitch_lua.cpp you'll see it
calls switch_cache_db_execute_sql_callback/switch_cache_db_execute_sql with
NULL as the err parameter. If it was given that would return NULL (no
error) or a the error string, the same one you see logged. That could be
copied to the object and exposed with a last_error() function.
