当我试图执行选择查询不执行。
在下面的代码行的执行程序停止后。
NSString *query = [NSString stringWithFormat:@"select * from maintable_master where din =? ",din];
最佳答案
如果din是整数,
NSString *query = [NSString stringWithFormat:@"select * from maintable_master where din =%d ",din];
如果din是字符串,
NSString *query = [NSString stringWithFormat:@"select * from maintable_master where din ='%@' ",din];
