[Mysql-cocoa-users] SMySQL_test

[Famille GOUREAU-S. <sui...@wa...>]

Hi,

I've got a problem with the following bunch of source file. It is used 
(and works perfectly) in SMySQL_Test, the software that tests SMySQL 
functions.

     SMySQLResult	*result;
     NSDictionary	*row;
     unsigned int	count, i;		

     result = [connection queryString:@"select * from test"];
     count = [result numOfFields];

     while (row = [result fetchRowAsDictionary]) {
         for (i=0; i<count; i++) {
             NSString	*name = [names objectAtIndex:i];
             NSLog(@"%@ : %@\n", name, [row objectForKey:name]);
         }
     }

My problem lies in the line : while (row = [result 
fetchRowAsDictionary]) {
I'm quite new with C, C++ or ObjC, but I thought that between 
the "(...)" of a while there should be a test. The "=" instruction is 
not a test...

Does anybody have an idea to explain this syntax that is perfectly 
understood by PB (if not by me) ?

Thanks.

Camille
