循环访问SQL数组

我试图通过学校列表进行循环，如果学校标识和关联表中的context_id之间没有交叉引用，请将其插入。循环访问SQL数组

我recieving以下错误：

Erreur(141,3): PL/SQL: SQL Statement ignored 
Erreur(141,24): PLS-00321: expression 'IDS' is inappropriate as the left hand side of an assignment statement 
Erreur(141,28): PL/SQL: ORA-00904: : invalid identifier 
Erreur(143,3): PL/SQL: Statement ignored 
Erreur(143,16): PLS-00302: component 'FIRST' must be declared

（在下面的代码块第一行被认为是136）

PROCEDURE APPLY_IMPLICITE(P_ID IN TBL_CONTEXTES.ID%TYPE, P_UID IN TBL_ECOLE_CONTEXTES.LAST_UID_MODIFICATION%TYPE) 
IS 
    TYPE IDS IS TABLE OF TBL_CONTEXTES.ID%TYPE INDEX BY PLS_INTEGER; 
    ROW_COUNT NUMBER; 
BEGIN 
    -- Get the IDs of all the schools 
    SELECT ECOLE_ID INTO IDS FROM MV_ECOLES; 
    -- Loop through all the schools 
    FOR i IN IDS.FIRST..IDS.LAST LOOP 
    -- Verify if a row exists 
    SELECT COUNT(*) INTO ROW_COUNT FROM TBL_ECOLE_CONTEXTES WHERE ECOLE_ID = IDS(i) AND ID = P_ID; 
    -- If no row exist, insert. 
    IF ROW_COUNT = 0 THEN 
     INSERT INTO TBL_ECOLE_CONTEXTES (ID, ECOLE_ID, LAST_UID_MODIFICATION) 
     VALUES (P_ID, IDS(i), P_UID); 
    END IF; 
    END LOOP; 

END APPLY_IMPLICITE;

你不应该需要一个循环。您只需插入所有非匹配的行：

查询看起来东西这样的：

INSERT INTO TBL_ECOLE_CONTEXTES 
    (ID, ECOLE_ID, LAST_UID_MODIFICATION) 
SELECT PID, ECOLE_ID, P_UID 
FROM TBL_ECOLE_CONTEXTES 
WHERE ECOLE_ID NOT IN (SELECT IDS FROM FROM MV_ECOLES WHERE ID = P_ID)

你的表结构不完全清楚，但应该是一般的想法。
