Question

i am using xcode ,and have a question in objective c ,maby you can help me .

my function gets a string, which she takes and put into an sql statement , and i am not sure how to do that because the statement is a char, and i found many ways to convert it.

i do this :

sql_for_event= " SELECT basic_pic,spriteSheet,sound FROM DataBase WHEN event= %c",[awaking_event UTF8String] ;

when sql_for_event is the statement, and awaking_event is a NSString i get to the function.
how can i do that ?

thanks a lot .

Answer 1

The %c specifier only prints a single char and it would need to be a part of an sprintf call with your scenario. An easier way would be

sql_for_event= [[NSString stringWithFormat:@"SELECT basic_pic,spriteSheet,sound FROM DataBase WHERE event= '%@'",awaking_event] UTF8String];
