Question

如何在PL / SQL中执行此操作？我试过但我有一些错误。

select * from account
打印最高BALANCE和STATUS ='avilable'
将最高BALANCE和STATUS ='已锁定'插入acc_locked表格

DECLARE
    CURSOR T IS
        SELECT CUST_ID,A_NO ,TYPE, BALANCE,STATUS
        FROM   ACCOUNT 
        where  STATUS=('نشط')
        order by BALANCE desc;

    CURSOR D IS
        SELECT CUST_ID,A_NO ,TYPE, BALANCE,STATUS
        FROM   ACC_LOCKED 
        order by BALANCE desc;

    ci  ACC_LOCKED.CUST_ID%TYPE;
    an  ACCOUNT.A_NO%TYPE;
    ty  ACCOUNT.TYPE%TYPE;
    ba  ACCOUNT.BALANCE%TYPE;
    st  ACCOUNT.STATUS%TYPE;

BEGIN
    OPEN T ;

    FOR p IN 1..3 LOOP
        FETCH T INTO ci  , an  ,ty  , ba  ,st  ;
        DBMS_OUTPUT.PUT_LINE( ci  ||'    '|| an||'    '||ty||'    '||ba ||'    '||st);
    END LOOP ;

    CLOSE T ;

    INSERT INTO ACC_LOCKED (CUST_ID,A_NO ,TYPE, BALANCE,STATUS)
    select CUST_ID,A_NO ,TYPE, BALANCE,STATUS 
    from   ACCOUNT
    where  STATUS=('موقوف')
    order by BALANCE desc;
END;

您还有3个步骤，您还列出了什么。
第1步=你做的光标，光标'T'，看起来很好。
第2步=循环通过光标'T'，看起来很好。
第3步=不起作用，因为你已经关闭了光标'T'。

也许这个更简单的例子会给你一个想法：

DECLARE
        CURSOR T IS 
               SELECT  CUST_ID,A_NO ,TYPE, BALANCE,STATUS
               FROM    ACCOUNT 
               WHERE   STATUS='Available'
               ORDER BY BALANCE DESC;
BEGIN
        FOR recT IN T LOOP
                -- You can print every value form cursor T this way.
                DBMS_OUTPUT.PUT_LINE(recT.Cust_Id);

                --Insert in table, add every column to insert here. 
                INSERT INTO Acc_Locked (Cust_Id, A_No)
                VALUES(recT.Cust_Id, recT.A_No);
        END LOOP;

        -- Save what you just inserted. 
        COMMIT;
END;
