DROP PROCEDURE v13
Name
DROP PROCEDURE -- remove a procedure.
Synopsis
DROP PROCEDURE [ IF EXISTS ] <name> [ ([ [ <argmode> ] [ <argname> ] <argtype> ] [, ...]) ] [ CASCADE | RESTRICT ]
Description
DROP PROCEDURE removes the definition of an existing procedure. To execute this command you must be a superuser or the owner of the procedure. All input (IN, IN OUT) argument data types to the procedure must be specified if this is an overloaded procedure. (This requirement is not compatible with Oracle databases. In Oracle, only the procedure name is specified. Advanced Server allows overloading of procedure names, so the procedure signature given by the input argument data types is required in the Advanced Server DROP PROCEDURE command of an overloaded procedure.)
Usage of IF EXISTS, CASCADE, or RESTRICT is not compatible with Oracle databases and is used only by Advanced Server.
Parameters
IF EXISTS
Do not throw an error if the procedure does not exist. A notice is issued in this case.
name
The name (optionally schema-qualified) of an existing procedure.
argmode
The mode of an argument: IN, IN OUT, or OUT. If omitted, the default is IN. Note that DROP PROCEDURE does not actually pay any attention to OUT arguments, since only the input arguments are needed to determine the procedure’s identity. So it is sufficient to list only the IN and IN OUT arguments. (Specification of argmode is not compatible with Oracle databases and applies only to Advanced Server.)
argname
The name of an argument. Note that DROP PROCEDURE does not actually pay any attention to argument names, since only the argument data types are needed to determine the procedure’s identity. (Specification of argname is not compatible with Oracle databases and applies only to Advanced Server.)
argtype
The data type of an argument of the procedure. (Specification of argtype is not compatible with Oracle databases and applies only to Advanced Server.)
CASCADE
Automatically drop objects that depend on the procedure, and in turn all objects that depend on those objects.
RESTRICT
Refuse to drop the procedure if any objects depend on it. This is the default.
Examples
The following command removes the select_emp procedure.
DROP PROCEDURE select_emp;
