[PHP] strange problem of mysql_query
hey, i have a sql string like below: select szs_content from szs_gy_ca where szs_shengchanhao='09-s525' and szs_guige='48B32/14-1 1/8' and szs_tuhao='48B32 1 1/8' the problem is that using mysql_query to run this sql string returns nothing,however, i can get one record through mysql query tool. i was wondering whether the double quote 48B32/14-1 1/8 makes this trouble.

The double quotes inside of that query won't cause any trouble, but you haven't shown us how you're executing the query with PHP. The usual is to do something like this: $query = select szs_content from szs_gy_ca where szs_shengchanhao='09-s525' and szs_guige='48B32/14-1 1/8\' and szs_tuhao='48B32 1 1/8'; $result = mysql_query($query); Note that the double quote there is escaped because you're already using double quotes as the string identifier in PHP. If that still doesn't give you the results you expect, it's more likely a logic problem than a syntax issue. Thanks, Ash http://www.ashleysheridan.co.uk

Break it down the basic of examples. show us how you... 1. connect to mysql from php 2. select your database in mysql from php 3. prepare the SQL query 4. executing said query 5. collecting/displaying the results of executed query As you can see, you gave us step 3. The problem could be in any of the other setups. -- Jim Lucas A: Maybe because some people are too annoyed by top-posting. Q: Why do I not get an answer to my question(s)?
