如何从一个mysql表INSERT INTO到另一个表并设置一列的值？

I need to insert data from table1 into table2. However, I would like to set the myYear column in table2 to 2010. But, there isn't a myYear Column in table1.

我需要将table1中的数据插入table2。但是,我想将table2中的myYear列设置为2010.但是,table1中没有myYear列。

So, my basic insert looks like:

所以,我的基本插入看起来像:

INSERT INTO  `table2` ( place, event ) 
SELECT place, event
FROM table1

Roughly, I'd like to do something like the following:

粗略地说,我想做类似以下的事情:

INSERT INTO `table2` ( place, event, SET myYear='2010' )
...

Is there a way to set the column value in the insert statement?

有没有办法在insert语句中设置列值?

2 个解决方案

#1

The following should do it:

以下应该这样做:

INSERT INTO `table2` (place, event, myYear) 
SELECT place, event, '2010'
FROM   table1;

Basic test case:

基本测试用例:

CREATE TABLE t1 (a int, b int);
CREATE TABLE t2 (c int);

INSERT INTO t2 VALUES (1),(2),(3),(4),(5);

INSERT INTO t1 SELECT c, 100 FROM t2;

SELECT * FROM t1;

+------+------+
| a    | b    |
+------+------+
|    1 |  100 | 
|    2 |  100 | 
|    3 |  100 | 
|    4 |  100 | 
|    5 |  100 | 
+------+------+
5 rows in set (0.00 sec)

INSERT INTO `table2` (place, event, myYear)
SELECT place, event, 2010
FROM table1
