PLSQL einfügen und zurückgeben ID-Formular-Trigger auf Tabelle

Question

Ich versuche, einfügen Anweisung innerhalb PLSQL einfügen und Rückgabe der ID aus Auslöser für Tabelle erzeugt, die Sequenzen aber Ich bekomme unter Fehler Dosis jemand hat eine Ahnung davon?

ORA-00905: fehlendes Stichwort

ORA-06512: bei "ADMIN.F_INSERT_ORDER_DATA", Zeile 22

ORA-06512: in Zeile 5

     DBMS_OUTPUT.PUT_LINE(vORDER_ID); 

     RETURN (vORDER_ID); 
    END F_INSERT_ORDER_DATA;

Berufung die Funktion, wie unten

declare 
    result varchar2(1024); 
begin 
    -- Call the function 
    result := F_INSERT_ORDER_DATA (1000,'----');

Es gibt nur wenige Probleme mit Ihrem Code. Zum einen ist die Bindung mit Rückgabeklausel nicht korrekt. Siehe unten, wie es bei dem Link funktioniert.

Execute Immediate with returning clause

CREATE OR REPLACE FUNCTION F_INSERT_ORDER_DATA(P_CUSTOMER_ID IN NUMBER, 
               P_NOTES  IN VARCHAR2) 
    RETURN NUMBER IS 
    vCreated_ON DATE := SYSDATE; 
    vORDER_ID NUMBER; 

BEGIN 
    vSQL := 'INSERT INTO orders' || '(ORDER_ID,' || 'CUSTOMER_ID,' || 
      'NOTES,' || 'CREATED_BY,' || 'CREATED_ON)' || 'VALUES (NULL,' --ORDER_ID Filled by trigger 
      || P_CUSTOMER_ID|| ',' --CUSTOMER_ID 
      || P_NOTES || ','--NOTES 
      || '''SYSTEM'',' --CREATED_BY 
      || '''' || vCREATED_ON || ''')' --CREATED_ON 
      || 'RETURNING ORDER_ID INTO :vORDER_ID'; 

    EXECUTE IMMEDIATE vSQL RETURNING INTO vORDER_ID ; 
    DBMS_OUTPUT.PUT_LINE(vORDER_ID); 

    RETURN(vORDER_ID); 
END F_INSERT_ORDER_DATA; 
/

Demo:

SQL> declare 
    2 var varchar2(4000); 
    3 var1 number; 
    4 begin 
    5 
    6 var := 'insert into dummy_emp(empid)values(2) RETURNING empID INTO :var1'; 
    7 
    8 execute immediate var 
    9  RETURNING INTO var1; 
10 commit; 
11  
12 dbms_output.put_line(var1);

PL/SQL procedure successfully completed. 

SQL> 

Dies ist, wie Sie benötigen, um Ihre Funktion in PLSQL Block zu nennen:

DECLARE  
    var  NUMBER; 
BEGIN 
    var := F_INSERT_ORDER_DATA(1000,'TEST'); 
    DBMS_OUTPUT.PUT_LINE (var); 
END; 

in Simple SQL Sie wie unten anrufen:

Select F_INSERT_ORDER_DATA(1000,'TEST') from dual;
