ALL_ARGUMENTS

2.46 ALL_ARGUMENTS

ALL_ARGUMENTS lists the arguments of the functions and procedures that are accessible to the current user.

Note:

The following changes have been made to this view:

Starting with Oracle Database 12c release 1 (12.1.0.2), this view omits procedures with no arguments. Prior to Oracle Database 12c release 1 (12.1.0.2), a procedure with no arguments was presented as a single row in this view.
Starting with Oracle Database 18c, this view displays only one row for an argument that is a composite type. Prior to Oracle Database 18c, this view displayed multiple rows for composite types.

To obtain information about composite type arguments, use the value of the TYPE_NAME column in this view to query the ALL_PLSQL_TYPES, ALL_PLSQL_TYPE_ATTRS, and ALL_PLSQL_COLL_TYPES views, which fully describe composite types.

See Oracle Database Upgrade Guide for more information about these changes.

`OBJECT_NAME`	`VARCHAR2(128)`		Name of the procedure or function
`PACKAGE_NAME`	`VARCHAR2(128)`		Name of the package
`OBJECT_ID`	`NUMBER`	`NOT NULL`	Object number of the object
`OVERLOAD`	`VARCHAR2(40)`		Indicates the `n`th overloading ordered by its appearance in the source; otherwise, it is NULL.

`POSITION`	`NUMBER`	`NOT NULL`	This column holds the position of this item in the argument list, or `0` for a function return value.
`SEQUENCE`	`NUMBER`	`NOT NULL`	Defines the sequential order of the argument. Argument sequence starts from 1. Return type comes first, and each argument will follow.
`DATA_LEVEL`	`NUMBER`	`NOT NULL`	Nesting depth of the argument for composite types Note: Starting with Oracle Database 18c, the value of this columns is always `0`, because this view displays only one row for each argument. This view no longer displays multiple rows for composite type arguments.
`DATA_TYPE`	`VARCHAR2(30)`		Datatype of the argument
`DEFAULTED`	`VARCHAR2(1)`		Specifies whether or not the argument is defaulted

`TYPE_OWNER`	`VARCHAR2(128)`		Owner of the type of the argument
`TYPE_NAME`	`VARCHAR2(128)`		Name of the type of the argument. If the type is a package local type (that is, it is declared in a package specification), then this column displays the name of the package.
`TYPE_SUBNAME`	`VARCHAR2(128)`		Relevant only for package local types. Displays the name of the type declared in the package identified in the `TYPE_NAME` column.
`TYPE_LINK`	`VARCHAR2(128)`		Relevant only for package local types when the package identified in the `TYPE_NAME` column is a remote package. This column displays the database link used to refer to the remote package.
`TYPE_OBJECT_TYPE`	`VARCHAR2(7)`		Displays the type of the type described by the `TYPE_OWNER`, `TYPE_NAME`, and `TYPE_SUBNAME` columns. Possible values are: `TABLE` `VIEW` `PACKAGE` `TYPE`
`PLS_TYPE`	`VARCHAR2(128)`		For numeric arguments, the name of the PL/SQL type of the argument. Null otherwise.
`CHAR_LENGTH`	`NUMBER`		Character limit for string datatypes
`CHAR_USED`	`VARCHAR2(1)`		Indicates whether the byte limit (`B`) or char limit (`C`) is official for the string
`ORIGIN_CON_ID`	`VARCHAR2(256)`		The ID of the container where the data originates. Possible values include: `0`: This value is used for rows in non-CDBs. This value is not used for CDBs. n: This value is used for rows containing data that originate in the container with container ID n (n = 1 if the row originates in root)
