Rong Rong updated FLINK-9502: ----------------------------- Description: This ticket is to enable generic Object type as element type by using SQL ANY in parameter / argument type mapping. This will enable support for use case such as: {code:java} public String eval(Object objArg) { /* ... */ } {code} The changes require here: 1. Introduce wildcard search and search rules for SQL ANY type usage. 2. Enabling wildcard search when concrete type search returns no match. was: This ticket is to enable generic Object type as element type by using SQL ANY in parameter / argument type mapping.
