Pl/SQL：如何對記錄表進行排序？

我是pl/sql新手！我想使用簡單的氣泡排序算法對記錄表進行排序。問題是什麼？Pl/SQL：如何對記錄表進行排序？

我在哪裏可以找到關於使用記錄表的更多信息？

DECLARE 
    text VARCHAR2(50); 
TYPE TIP_VECTOR 
IS 
    TABLE OF INT INDEX BY BINARY_INTEGER; 
TYPE contorRecord 
IS 
    record 
    (
     codASCII VARCHAR2(3), 
     contor SMALLINT); 
TYpe tip_vector2 
IS 
    TABLE OF contorRecord; 
    VECTOR TIP_VECTOR; 
    VECTOR2 TIP_VECTOR2 := TIP_VECTOR2(); 
    aux tip_vector2 := tip_vector2(); 
    v_char VARCHAR2(3); 
    FLAG BOOLEAN := TRUE; 
    t smallint; 
    n  SMALLINT := 1; 
    ind SMALLINT := 0; 

begin 
     AUX.EXTEND(1); 
      WHILE(FLAG) 
        LOOP 
        FLAG := FALSE; 
    -- here is the problem; what i'm doing wrong? 
        FOR I IN 1..(vector2.count-1) LOOP 
    -- here is the problem; what i'm doing wrong? 
        IF VECTOR2(I).CONTOR < VECTOR2(I+1).contor THEN 
        AUX   := VECTOR(I+1); 
        VECTOR(i+1) := VECTOR(I); 
        VECTOR(I) := AUX; 
        FLAG  := TRUE; 
        END IF; 
        END LOOP; 
        END LOOP; 
end;

錯誤：

你有你的類型和變量混淆。嘗試：

DECLARE 
    TYPE contorRecord IS record (codASCII VARCHAR2(3), contor SMALLINT); 
    TYpe tip_vector2 IS TABLE OF contorRecord; 
    VECTOR2 TIP_VECTOR2 := TIP_VECTOR2(); 
    aux contorRecord; 
    FLAG BOOLEAN := TRUE; 
begin 
    WHILE(FLAG) 
    LOOP 
     FLAG := FALSE; 
     FOR I IN 1..(vector2.count-1) LOOP 
      IF VECTOR2(I).CONTOR < VECTOR2(I+1).contor THEN 
       AUX   := VECTOR2(I+1); 
       VECTOR2(i+1) := VECTOR2(I); 
       VECTOR2(I) := AUX; 
       FLAG  := TRUE; 
      END IF; 
     END LOOP; 
    END LOOP; 
end;
