1. A method of providing parameterized queries in complex event processing (CEP) environment, the method comprising: providing a query template which includes one or more bind variables, wherein the one or more bind variables are typeless within the CEP environment; 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 corresponding sets of parameters; inserting one or more arbitrary predicates into the query template, based on the one or more bind variables being typeless; substituting the bound one or more bind variables with the corresponding sets of parameters; determining that the sets of parameters correspond to the same bind variable; based on the sets of parameters, generating a single parameterized query which is a template that provides possible values for the bound one of more bind variables; determining a placeholder occurring in the single parameterized query for processing an event stream; substituting the placeholder at runtime with parameter values corresponding to the sets of parameters; generating multiple customized queries and views which differ by at least only one variable based on the substituting; instantiating a new query for each of the sets of parameters which correspond to the same bind variable as a continuous query; and executing the continuous query to process the event stream.
