[Dev-C++] Help with sprintf

[<fer...@te...>]

Hi! In this:
sprintf(sql_lt,"select data,titulo,categoria,anotacao,ROWID from anot 
where %s like '%s';",prcampo,prprocurar);
I get something like this:
select data,titulo,categoria,anotacao,ROWID from anot where titulo like 
'mytitle';
But when I try place a % there is an error, or the value appears wrong 
or I get a NULL string, by example, I need this output
select data,titulo,categoria,anotacao,ROWID from anot where titulo like 
'%mytitle%';
I try to place one %, two %(like tell in libc reference), \% and nothing 
gives what I want.
Can you show me how to do this?

Thanks.
