This is nothing to do with MySQL++. This is basic text processing
problem.
From this and the rest of your message, I get the impression that
you're just starting to learn about programming. That's great, but
this is not the place to get that education.
This might help clear the fog about the connection between MySQL++
string structures and C strings:
mysqlpp::sql_text dbstring;
char ac[10];
strncpy(ac, dbstring.c_str(), sizeof(ac));
ac[sizeof(ac) - 1] = '\0';
That will copy dbstring into a null-terminated array of characters --
a C string -- truncating it to the maximum size of the array, giving
at most 9 characters.

You're not going to get much help for such vague problem descriptions
as this. The best you can hope for is commiseration. If you want a
solution, show the code and give the exact text of the error you got
when trying to compile or run it.
