custom errors?

[fife]

Hi.  I was just wondering if it is possible to write custom mysql errors.  I have hunted around for some but cant find any.  Currently I write my errors like...

 

or die (mysql_error());

 

How ever I see this as a problem!  As Im not the best coder there are bound to be errors in my code.  I dont want somebody who knows what they are doing to cause an error and then doing it (mysql_error()) will point them in the right direction to what I have missed.

 

I would rather have my own error saying what line the issue is with.  I have tried.....

 

 

or die (mysql_error(My personal error here))

 

However this does not work.

 

Please help.  Thank you
