V$SQLFN_METADATA

V$SQLFN_METADATA contains metadata about operators and built-in functions. Note that this view does not contain information about arguments because the number of arguments will be different for various functions. Information about arguments is contained in V$SQLFN_ARG_METADATA, which can be joined with V$SQLFN_METADATA to get information about any function and its arguments.
