ALL_ARGUMENTS

OWNER

VARCHAR2(128)

NOT NULL

Owner of the object

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 nth overloading ordered by its appearance in the source; otherwise, it is NULL.

SUBPROGRAM_ID

NUMBER

Unique subprogram identifier

ARGUMENT_NAME

VARCHAR2(128)

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(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.

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)
