如何组合下面的sql？

2009-11-01 01:30:00

Exp：ContactName = Andy，contact_ID是＆＃39; 0001＆＃39;。

所以第二个sql看起来应该是

NOW()

如何将两个sql组合成一个sql？

Answer 1

你可以像这样使用Insert into ... select ....from ...

INSERT INTO PurchaseInfo (ContactName)
SELECT 'ContactName ' + ContactName 
FROM Contact WHERE Contact_ID = '0001'

Answer 2

我假设您需要在列中使用名称的静态值，我只是在@Triv的答案中稍作修改

INSERT INTO PurchaseInfo (ContactName)
SELECT 'ContactName ' + ContactName AS Expr1
FROM Contact WHERE Contact_ID = '0001'

Answer 3

INSERT INTO table2 (column1, column2, column3, ...)
SELECT column1, column2, column3, ...
FROM table1
WHERE condition;

Answer 4

INSERT INTO PurchaseInfo (ContactName) 
VALUES (CONCAT('Contact Name',SELECT ContactName FROM Contact WHERE Contact_ID = '0001'));

只是更新@TriV答案，我也是NEWBIE给我一个尝试：）

Answer 5

如果您使用的是SQLServer，请执行此操作：

DECLARE @strContactName varchar(50)
select @strContactName = ContactName  from Contact WHERE Contact_ID = '0001';
INSERT INTO PurchaseInfo (ContactName) VALUES (@strContactName);

SQL INSERT INTO与SELECT＆amp;串
