Synopsis ¶

DROP FUNCTION [ IF EXISTS ] function_name
    ( [ [ arg_name ] arg_type [, ...] ] )

DROP FUNCTION drops a function. A function name and argument types must be specified.

IF EXISTS:	Do not produce an error if the function doesn’t exist.
function_name:	The name of the function to drop.
arg_name:	The name given to an argument. Function arguments do not retain names, but you can name them in your query for documentation purposes. Note that `DROP FUNCTION` will ignore argument names, since only the argument data types are needed to identify the function.
arg_type:	The data type of an argument, if any. See Data types for more information about the supported types.
