Editing Cast General

Schema of source type and Source type
The schema and name of the source data type of the cast.

Schema of target type and Target type
The schema and name of the target data type of the cast.

Schema of function and Function
The function used to perform the cast. The function name may be schema-qualified. If it is not, the function will be looked up in the schema search path. The function's result data type must match the target type of the cast.

If no function is specify, indicates that the source type and the target type are binary compatible, so no function is required to perform the cast.

Implicit
Indicates that the cast may be invoked implicitly in any context.

Assignment
Indicates that the cast can be invoked implicitly in assignment contexts.
