DESCRIBE FUNCTION ¶

Describes the specified user-defined function (UDF) or external function, including the signature (i.e. arguments),return value, language, and body (i.e. definition).

DESCRIBE can be abbreviated to DESC.

See also:: DROP FUNCTION ,ALTER FUNCTION ,CREATE FUNCTION ,SHOW USER FUNCTIONS ,SHOW EXTERNAL FUNCTIONS

Syntax¶

DESC[RIBE]FUNCTION<name>([<arg_data_type>][,...])

Copy

Parameters¶

name: Specifies the identifier for the function to describe. If the identifier contains spaces or special characters, the entire string mustbe enclosed in double quotes. Identifiers enclosed in double quotes are also case-sensitive.
arg_data_type[,...]: Specifies the data type of the argument(s), if any, for the function. The argument data types are necessary because functions supportname overloading (i.e. two functions in the same schema can have the same name) and the argument data types are used to identify thefunction.

Usage notes¶

To post-process the output of this command, you can use thepipe operatoror theRESULT_SCAN function. Both constructs treat the output as a result set thatyou can query.
