I am trying to get data from mysql as follows:

$data->render_table(“st_user”,“us_id”,“us_name”);

and getting error:

<b>Fatal error</b>:  Uncaught exception 'Exception' with message 'MySQL operation failed
Unknown column '' in 'where clause'' in D:\\a\\doc\\codebase\\db_common.php:1093
Stack trace:
#0 D:\\a\\doc\\codebase\\db_common.php(1093): MySQLDBDataWrapper::query()

#6 {main}
  thrown in <b>D:\\a\\doc\\codebase\\db_common.php</b> on line <b>1093</b><br />

Also i tried to use this:

$data->render_table(“st_user”,“us_id”,“us_name”, “”, “”);

But result the same. Not sure why but db_common.php in the function “build_where” $relation gets 0 instaed of “false” or “”. This is because later “MySQLDBDataWrapper->query” generates incorrect query:

SELECT us_id,us_name FROM st_user WHERE ( = '0' OR IS NULL )

As i understand the query should be:

SELECT us_id,us_name FROM st_user

Is it related to php version (i am using 5.0.3)

Can you share the full init code ?
Also, as extra parameters are optional, you an try to use

$data->render_table("st_user","us_id","us_name");
