the funny thing is. i was essentially doing the same thing. i just now used the
mysqlpp::sql_text dbstring, set it equal to row[0], and its running right. TYVM!!? I
didn't know that i woulda needed to use an sql_string.

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.?
