ABSTRACT:
A method, apparatus and computer program product are provided for implementing enhanced query governor functions. Query execution includes first checking for a timeout value for a query. Responsive to identifying a timeout value for the query, an execution time for the query is reset and a monitor for each timeout value for the query is started. Then the execution of the query is started. The execution of predefined events is monitored during the execution of the query. The predefined events include a begin or end of processing of at least one of a trigger and a user defined function (UDF). Execution status of the query is periodically checked. Responsive to identifying the query is executing, checking for any expired timeout value is performed. The execution of the query is halted responsive to an identified expired timeout value.
