这个错误是因为你的 SQL 语句不完整，无法被识别。这段代码看起来像是 PL/SQL 代码，但你没有写 DECLARE 开头的语句块声明变量。如果你想使用 PL/SQL 语法，可以将整段代码放在 BEGIN 和 END 之间，并在 DECLARE 声明区域定义变量。如果你只是想执行简单的 SQL 语句，则可以省略 BEGIN 和 END，直接执行 INSERT INTO ... VALUES ...; COMMIT; 即可。

BEGIN FOR i IN 1..10 LOOP INSERT INTO SHIFT (ShiftID, StartTime, EndTime, StoreID, EmployeeID) VALUES (i, SYSDATE - DBMS_RANDOM.VALUE(1, 7), SYSDATE - DBMS_RANDOM.VALUE(0, 6), i, i); END LOOP; COMMIT; END; FOR i IN 1..10 LOOP * ERROR at line 2: ORA-06550: line 2, column 5: PLS-00103: Encountered the symbol "FOR" when expecting one of the following: := .

这段代码有两个问题：

1. 缺少一个语句块的结尾。你需要在第一段代码的最后加上 `END;` 来结束整个语句块。

2. 你不能在 PL/SQL 块外使用 `FOR` 循环。你需要将两个 `FOR` 循环放在一个 PL/SQL 块内，像这样：

BEGIN
  FOR i IN 1..10 LOOP
    INSERT INTO SHIFT (ShiftID, StartTime, EndTime, StoreID, EmployeeID)
    VALUES (i, SYSDATE - DBMS_RANDOM.VALUE(1, 7), SYSDATE - DBMS_RANDOM.VALUE(0, 6), i, i);
  END LOOP;
  
  FOR i IN 1..10 LOOP
    -- do something else
  END LOOP;
  
  COMMIT;
END;
