I use mysql C API and for *escaping* the data i use the mysql_real_escape_string()the mysql native function.

Thanks, Make sure to use mysql_real_query with the right length. because mysql_query is a macro for mysql_real_query with an additionnal parameters given by strlen(query_string); which culd lead to the broken result. http://dev.mysql.com/doc/mysql/en/mysql-real-query.html -- Philippe Poelvoorde COS Trading Ltd. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: Question about BLOB
Hi, I think that I have seen many times the advice not to store the images in MySQL, but to store them on the hard disk while putting the path to them in the database. They could be accessed much faster this way.

Re: Question about BLOB
In my data structure I have many BLOBs which are not images - so I am hoping that MySQL can indeed deal with BLOBs ok ?

Re: Question about BLOB
I have never had a problem storing BLOBs in MySQL or any other DB for that fact. I have on many occasions forgot to use the proper methods for send a BLOB to the db. That means proper escaping, etc. On Tue, 2 Aug 2005, Andy Hilton wrote: In my data structure I have many BLOBs which are not images - so I am hoping that MySQL can indeed deal with BLOBs ok ?
