对多个SELECT语句使用INSERT INTO

Question

我试图在表格中插入多行。几乎所有这些行的值都与同一个表上的另一组记录相匹配，所以我很好奇我是否可以使用多个SELECT语句编写单个INSERT语句来插入多行。就像这样：

INSERT INTO table (col1, col2, col3, col4) 

SELECT (newRecordID, col2, col3, col4) 
FROM table WHERE col1 = oldRecordID AND col4 = 0 
SELECT (newRecordID, col2, col3, col4) 
FROM table WHERE col1 = oldRecordID AND col4 = 1 
SELECT (newRecordID, col2, col3, col4) 
FROM table WHERE col1 = oldRecordID AND col4 = 2 
SELECT (newRecordID, col2, col3, col4) 
FROM table WHERE col1 = oldRecordID AND col4 = 3 

这可能吗？最后，它应该插入4行，所有行都具有相同的NewRecordID，col4值为0-3，其他col值取自同一个表上相应的OldRecordID。当我运行它时，它只运行第一个INSERT SELECT语句，然后将其他运行作为它们自己的SELECT语句。我在连接这些东西时错过了什么？我总是可以多次运行它并每次更改值，但我想知道是否有办法避免这种情况。我欣赏和帮助或有用的提示。

感谢

你可以与联盟，其加入他们到一个记录连接：

INSERT INTO table (col1, col2, col3, col4) 

SELECT (newRecordID, col2, col3, col4) 
FROM table WHERE col1 = oldRecordID AND col4 = 0 
union 
SELECT (newRecordID, col2, col3, col4) 
FROM table WHERE col1 = oldRecordID AND col4 = 1 
union 
SELECT (newRecordID, col2, col3, col4) 
FROM table WHERE col1 = oldRecordID AND col4 = 2 
union 
SELECT (newRecordID, col2, col3, col4) 
FROM table WHERE col1 = oldRecordID AND col4 = 3 

Answer 2

INSERT INTO table (col1, col2, col3, col4) 

SELECT (newRecordID, col2, col3, col4) 
FROM table WHERE col1 = oldRecordID AND col4 IN(0,1,2,3)
