Question

我希望在表中插入记录时对查询使用union。插入也具有一些硬编码值。其余的价值观来自工会。例如..

INSERT INTO my_test_one (name, sirname, Dept)
VALUES
  ((select 'name1','sirname1', Dept FROM my_test_one_backup WHERE dept = 500 
    union all
    select 'name1','sirname1', Dept FROM my_test_one_backup WHERE dept = 501 ));

Answer 1

尝试：

INSERT INTO my_test_one (name, sirname, Dept) 
(select 'name1','sirname1', Dept 
   FROM my_test_one_backup 
  WHERE dept = 500      
UNION ALL
 select 'name1','sirname1', Dept 
   FROM my_test_one_backup 
  WHERE dept = 501 );

希望它有所帮助...

Answer 2

我认为你这里不需要VALUES。（INSERT INTO ... ( ... ) SELECT ...）

Answer 3

为什么不使用两个插入而不是使用union all？

INSERT INTO my_test_one (name, sirname, Dept)
SELECT 'name1','sirname1', Dept FROM my_test_one_backup WHERE dept = 500;

INSERT INTO my_test_one (name, sirname, Dept)
SELECT 'name1','sirname1', Dept FROM my_test_one_backup WHERE dept = 501;

或

INSERT INTO my_test_one (name, sirname, Dept)
SELECT 'name1','sirname1', Dept FROM my_test_one_backup WHERE dept in (500,501);

Answer 4

你可以这样做：

如果表格不存在，您可以使用：

SELECT 'name1' [name],'sirname1' [sirname], Dept INTO my_test_one FROM my_test_one_backup WHERE dept = 500 
UNION ALL
SELECT 'name1','sirname1', Dept FROM my_test_one_backup WHERE dept = 501

否则请使用：

INSERT INTO my_test_one (name, sirname, Dept)
SELECT 'name1','sirname1', Dept FROM my_test_one_backup WHERE dept in (500,501)

我想使用union ALL从select语句插入
