Question

我正在尝试执行此SQL查询：

INSERT INTO ItemAssignments(EmployeeId, ItemId, ModifiedOn) 
    (SELECT Id FROM Employees WHERE Acronym ='ardsd',2,'2019-07-10 09:03:55.830'),
    (SELECT Id FROM Employees WHERE Acronym ='bsadf',2,'2019-07-10 09:03:55.830'),
    (SELECT Id FROM Employees WHERE Acronym ='casde',3,'2019-07-10 09:03:55.830'),
    (SELECT Id FROM Employees WHERE Acronym ='dasas',3,'2019-07-10 09:03:55.830');

SELECT表达式和下一个参数之间的错误。

我试图将SELECT放在方括号中-但这无济于事。

请告诉我在这种情况下我该怎么办？

Answer 1

使用一个带有UNION的SELECT作为源：

INSERT INTO ItemAssignments(EmployeeId,ItemId,ModifiedOn) 
SELECT id, 2, '2019-07-10 09:03:55.830'
FROM Employees 
WHERE Acronym in ('ardsd', 'bsadf')

UNION ALL

SELECT id, 3, '2019-07-10 09:03:55.830'
FROM Employees 
WHERE Acronym in ('casde', 'dasas');

Answer 2

您似乎想要这样的逻辑：

INSERT INTO ItemAssignments(EmployeeId, ItemId, ModifiedOn) 
    SELECT Id,
           (CASE WHEN Acronym in ('ardsd', 'bsadf') THEN 2
                 ELSE 3
            END),
           '2019-07-10 09:03:55.830'
    FROM Employees
    WHERE Acronym in ('ardsd', 'bsadf', 'casde', 'dasas')

SQL错误：“，”附近的语法不正确，在插入中使用了select
