MySQL的複製行，使用PHP在同一時間

Question

我知道你可以這樣做：

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你需要更新這些列作爲a, b, c, "string"

到什麼說白了我想要說的聲明：

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

UPDATE

於是我就這樣：

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

它選擇的3行，在「C」柱不同的條目，並通過插入3行中的所有完全相同的更新「AnotherTable」。他們應該是不同的值，雖然...

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，你應該非常小心注入$ somevar那樣。真的，你應該使用準備好的語句，所以它會...

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

和CustomValue通過綁定到語句的值來設置。這裏有一些例子：http://www.php.net/manual/en/pdostatement.bindvalue.php
