    You should remove parentheses around the table name:

    sprintf(Query,"DELETE FROM '%s' where id = (%d)",tb1,idt1) ;

    MySQL considers queries like this syntax errors:

    delete from (mytable) where id=2;

    You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘(mytable) where id=2’ at line 1

    (I’ll assume that you know everything about SQL injection attacks, and that neither tb1 nor idt1 are constructed from user input in any shape or form).
