Hello Konstantin,
this code is buggy, because 'new' is not a valid C operator.
And MYSQL is a struct not an object.
The 'new' operator allocates memory for objects (C++).
In C you?ve to use the malloc function.
Take a look at the libmysqltest example, which comes with your distribution.
Please look in the mysql manual before you ask questions (if you already
haven't)

Depending upon the function of the table, you might consider
designing your table such that duplicates aren't possible (e.g.

Other than that, try dumping your table, removing the rows you
