OPEN_CURSOR v17

Suggest edits

The OPEN_CURSOR function creates a cursor. A cursor must be used to parse and execute any dynamic SQL statement. Once a cursor is open, you can reuse it with the same or different SQL statements. You don't have to close the cursor and reopen it to reuse it.

<c> INTEGER OPEN_CURSOR

Parameters

c

Cursor ID number associated with the newly created cursor.

Examples

This example creates a new cursor:

DECLARE
    curid           NUMBER;
    v_sql           VARCHAR2(150);
    v_status        INTEGER;
BEGIN
    v_sql:='INSERT INTO dept VALUES (50,''HR'',''LOS ANGELES'')';
    curid := DBMS_SQL.OPEN_CURSOR;
    DBMS_SQL.PARSE(curid,v_sql,DBMS_SQL.native);
    v_status := DBMS_SQL.EXECUTE(curid);
    DBMS_OUTPUT.PUT_LINE('Number of rows processed: ' || v_status);
    DBMS_SQL.CLOSE_CURSOR(curid);
END;
