View as plain text  













 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.?
