Examples of org.odmg.OQLQuery.bind()

org.odmg.OQLQuery.bind()
Bind a parameter to the query. A parameter is denoted in the query string passed to create by $i, where i is the rank of the parameter, beginning with 1. The parameters are set consecutively by calling this method bind. The ith variable is set by the ith call to the bind method. If any of the $i are not set by a call to bind at the point execute is called, QueryParameterCountInvalidException is thrown. The parameters must be objects, and the result is an Object. Objects must be used instead of primitive types (Integer instead of int) for passing the parameters.
If the parameter is of the wrong type, QueryParameterTypeInvalidException is thrown. After executing a query, the parameter list is reset. @parameter A value to be substituted for a query parameter. @exception QueryParameterCountInvalidException The number of calls tobind has exceeded the number of parameters in the query. @exception QueryParameterTypeInvalidException The type of the parameter doesnot correspond with the type of the parameter in the query.
