我是 Oracle 脚本新手，在将数据插入全局临时表时遇到问题。这是我在 Toad 中创建的脚本：

        v_sql LONG; 
    BEGIN
        SELECT COUNT(*) INTO tempTwwIDExist FROM USER_TABLES WHERE table_name = UPPER('tempTwwID');
        DBMS_OUTPUT.PUT_LINE(tempTwwIDExist);

        IF (tempTwwIDExist > 0) THEN 
        BEGIN
                EXECUTE IMMEDIATE 'TRUNCATE TABLE tempTwwID';
                EXECUTE IMMEDIATE 'DROP TABLE tempTwwID';
        END;
        END IF;

        EXECUTE IMMEDIATE 'CREATE GLOBAL TEMPORARY TABLE tempTwwID (id NUMBER NOT NULL, SITEID NUMBER) ON COMMIT DELETE ROWS';

        EXECUTE IMMEDIATE 'INSERT INTO tempTwwID (id, SITEID) VALUES (1,123)';

    END;
    /

但是，当我运行 SELECT 语句以从 tempTwwID 获取所有数据时，尽管此脚本使用 EXECUTE IMMEDIATE 运行 …
