對多個SELECT語句使用INSERT INTO

Question

我試圖在表格中插入多行。幾乎所有這些行的值都與同一個表上的另一組記錄相匹配，所以我很好奇我是否可以使用多個SELECT語句編寫單個INSERT語句來插入多行。就像這樣：

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 

這可能嗎？最後，它應該插入4行，所有行都具有相同的NewRecordID，col4值爲0-3，其他col值取自同一個表上相應的OldRecordID。當我運行它時，它只運行第一個INSERT SELECT語句，然後將其他運行作爲它們自己的SELECT語句。我在連接這些東西時錯過了什麼？我總是可以多次運行它並每次更改值，但我想知道是否有辦法避免這種情況。我欣賞和幫助或有用的提示。

感謝

你可以與聯盟，其加入他們到一個記錄連接：

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)
