mysql真正的转义字符串,LIKE没有取任何结果

Question

我有一个mysql查询

mysql_query("SELECT name,symbol FROM scode WHERE change='$change' 
AND product='$product' AND series='$typeo' 
AND (name LIKE '%$check%' OR symbol LIKE '%$check%') LIMIT 5");

它完美地工作但是如果我尝试使用mysql字符串使用相同的查询,则查询不返回任何结果.我试过这样的

$query= sprintf("SELECT name,symbol FROM `scode` WHERE change='%s' 
AND product='%s' AND series='%s' AND (name LIKE '%s' OR symbol LIKE '%s') 
LIMIT 5",
mysql_real_escape_string($change),
mysql_real_escape_string($product),
mysql_real_escape_string($typeo),
mysql_real_escape_string($check),
mysql_real_escape_string($check));

$fetch= mysql_query($query);

如何进行有效的查询？有人可以帮帮我吗？谢谢.

好吧不,它不会起作用,因为在第一个你做了LIKE %term%,在第二个你做了LIKE term.尝试添加%%,像这样:

$query= sprintf("SELECT name,symbol FROM `scode` WHERE change='%s' AND product='%s' AND series='%s' AND (name LIKE '%%%s%%' OR symbol LIKE '%%%s%%') LIMIT 5",mysql_real_escape_string($change),mysql_real_escape_string($product),mysql_real_escape_string($typeo),mysql_real_escape_string($check),mysql_real_escape_string($check));

$fetch= mysql_query($query);
