1. A method of providing parameterized queries in complex event processing (CEP), the method comprising: providing a query template which includes one or more bind variables; providing sets of parameters corresponding to the one or more bind variables; parsing the query template to determine positions of the one or more bind variables; scanning the provided sets of parameters to determine which of the sets of parameters are to be bound to the one or more bind variables; binding the one or more bind variables which are determined to be bound to the sets of parameters; and substituting the bound one or more bind variables with the corresponding sets of parameters.
