OPEN FOR Statement

The OPEN FOR statement associates a cursor variable with a multiple-row query, allocates database resources to process the query, identifies the result set, and positions the cursor before the first row of the result set. (If the query has a FOR UPDATE clause, processing the query includes locking the rows of the result set—see "SELECT FOR UPDATE and FOR UPDATE Cursors".)

Semantics

bind_argument

An expression whose value replaces its corresponding placeholder in select_statement or dynamic_string at run time. You must specify a bind_argument for every placeholder.

cursor_variable_name

The name of a cursor variable. If the cursor variable is the formal parameter of a subprogram, it must not have a return type. For information about cursor variables as subprogram parameters, see "Cursor Variables as Subprogram Parameters".

dynamic_string

A string literal, string variable, or string expression; of type CHAR, VARCHAR2, or CLOB; that represents a multiple-row SQL SELECT statement (not a PL/SQL SELECT INTO statement).

See:

Oracle Database SQL Language Reference for SELECT statement syntax

host_cursor_variable_name

The name of a cursor variable that was declared in a PL/SQL host environment and passed to PL/SQL as a bind argument. The data type of the cursor variable is compatible with the return type of any PL/SQL cursor variable. Do not put space between the colon (:) and host_cursor_variable_name.

IN, OUT, IN OUT

Parameter modes of bind arguments. An IN bind argument passes its value to the select_statement or dynamic_string. An OUT bind argument stores a value that dynamic_string returns. An IN OUT bind argument passes its initial value to dynamic_string and stores a value that dynamic_string returns. The default parameter mode for bind_argument is IN.

select_statement

A string literal, string variable, or string expression; of type CHAR, VARCHAR2, or CLOB; that represents a multiple-row SQL SELECT statement (not a PL/SQL SELECT INTO statement).

See:

Oracle Database SQL Language Reference for SELECT statement syntax

using_clause

Specifies bind arguments.
