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.
