The odbc_errormsg() function was added in PHP 4.0.5
To get odbc error messages before that, use the $php_errormsg global and turn Track Errors ON in php.ini
Descriptionstring odbc_errormsg ( [resource connection_id] )
Returns a string containing the last ODBC error message, or an empty string if there has been no errors. If connection_id is specified, the last state of that connection is returned, else the last state of any connection is returned.
This function returns meaningful value only if last odbc query failed (i.e. odbc_exec() returned FALSE).
