ALL_ARGUMENTS

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

Column Datatype NULL Description
OWNER VARCHAR2(30) NOT NULL Owner of the object
OBJECT_NAME VARCHAR2(30)   Name of the procedure or function
PACKAGE_NAME VARCHAR2(30)   Name of the package
OBJECT_ID NUMBER NOT NULL Object number of the object
OVERLOAD VARCHAR2(40)   Indicates the nth overloading ordered by its appearance in the source; otherwise, it is NULL.
SUBPROGRAM_ID NUMBER   Unique subprogram identifier
ARGUMENT_NAME VARCHAR2(30)   If the argument is a scalar type, then the argument name is the name of the argument. A null argument name is used to denote a function return. If the function return or argument is a composite type, this view will have one row for each attribute of the composite type. Attributes are recursively expanded if they are composite.

The meanings of ARGUMENT_NAME, POSITION, SEQUENCE, and DATA_LEVEL are interdependent. Together, as a tuple, they represent a node of a flattened tree.

ARGUMENT_NAME can refer to any of the following:

  • Return type, if ARGUMENT_NAME is null and DATA_LEVEL = 0

  • The argument that appears in the argument list if ARGUMENT_NAME is not null and DATA_LEVEL = 0

  • Attribute name of the composite type if ARGUMENT_NAME is not null and DATA_LEVEL > 0;

  • A collection element type if ARGUMENT_NAME is null and DATA_LEVEL > 0;

POSITION NUMBER NOT NULL If DATA_LEVEL is zero, then this column holds the position of this item in the argument list, or zero for a function return value.If DATA_LEVEL is greater than zero, then this column holds the position of this item with respect to its siblings at the same DATA_LEVEL. So, for a referenced record field, this is the index of the field within the record. For a referenced collection element, this is 1 (because collection elements do not have siblings.)
SEQUENCE NUMBER NOT NULL Defines the sequential order of the argument and its attributes. Argument sequence starts from 1. Return type and its recursively expanded (preorder tree walk) attributes will come first, and each argument with its recursively expanded (preorder tree walk) attributes will follow.
DATA_LEVEL NUMBER NOT NULL Nesting depth of the argument for composite types
DATA_TYPE VARCHAR2(30)   Datatype of the argument
DEFAULTED VARCHAR2(1)   Specifies whether or not the argument is defaulted
DEFAULT_VALUE LONG   Reserved for future use
DEFAULT_LENGTH NUMBER   Reserved for future use
IN_OUT VARCHAR2(9)   Direction of the argument:
  • IN

  • OUT

  • IN/OUT

DATA_LENGTH NUMBER   Length of the column (in bytes)
DATA_PRECISION NUMBER   Length in decimal digits (NUMBER) or binary digits (FLOAT)
DATA_SCALE NUMBER   Digits to the right of the decimal point in a number
RADIX NUMBER   Argument radix for a number
CHARACTER_SET_NAME VARCHAR2(44)   Character set name for the argument
TYPE_OWNER VARCHAR2(30)   Owner of the type of the argument
TYPE_NAME VARCHAR2(30)   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(30)   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.
PLS_TYPE VARCHAR2(30)   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
