MySQL的复制行，使用PHP在同一时间

Question

我知道你可以这样做：

INSERT INTO AnotherTable (a, b, c, d) 
SELECT a, b, c, d 
FROM SomeTable 
WHERE SomeColumn = 1 

但如果不是SELECT a, b, c, d你需要更新这些列作为a, b, c, "string"

到什么说白了我想要说的声明：

INSERT INTO AnotherTable (a, b, c, d) 
SELECT a, b 
FROM SomeTable 
WHERE SomeColumn = 1 
// And put "string" into d 

UPDATE

于是我就这样：

INSERT INTO AnotherTable (a, b, c, d) 
SELECT a, b, c, 'string' 
FROM SomeTable 
WHERE SomeColumn = 1 

它选择的3行，在“C”柱不同的条目，并通过插入3行中的所有完全相同的更新“AnotherTable”。他们应该是不同的值，虽然...

Answer 1

INSERT INTO AnotherTable (a, b, c, d) 
SELECT a, b,"SOME VALE","SOMEVALUE2" 
FROM SomeTable 
WHERE SomeColumn = 1 

Answer 2

INSERT INTO AnotherTable (a, b, c, d) 
SELECT a, b, $somevar, 'fixed string' 
FROM SomeTable 
WHERE SomeColumn = 1 

但是，你应该非常小心注入$ somevar那样。真的，你应该使用准备好的语句，所以它会...

INSERT INTO AnotherTable (a, b, c, d) 
SELECT a, b, :CustomValue, 'fixed string' 
FROM SomeTable 
WHERE SomeColumn = 1 

和CustomValue通过绑定到语句的值来设置。这里有一些例子：http://www.php.net/manual/en/pdostatement.bindvalue.php
