Comment 2 Andris Pavenis 2010-05-19 07:33:42 UTC
There are some more warning coming from sql_create_n:

--------------- example ----------------
#include <mysql++.h>
#include <ssqls.h>

    1, 3,

    mysqlpp::sql_int,             user_id,
    mysqlpp::sql_varchar,         user_name,
    mysqlpp::sql_varchar,         user_hash);

std::vector<test_table> data;

[apavenis@callisto mysql++]$ g++ -c -Wall -Wextra -I/usr/include/mysql++ -I/usr/include/mysql sql_create_warn.cpp
sql_create_warn.cpp:10: warning: type qualifiers ignored on function return type

I also got one more warning:
 warning: ‘<unnamed>::sync_user::names’ defined but not used
from real code (not example) friom the same source line but failed to reproduce it in this example.

Comment 3 Remi Collet 2010-05-19 07:35:41 UTC
s this bug reported upstream ? (link ?)
Is this patch from upstream SVN ? (commit ref ?)

Comment 4 Andris Pavenis 2010-05-19 08:10:38 UTC
I haven't reported it and did not check SVN version.

Comment 5 Remi Collet 2010-05-19 17:00:58 UTC
Read : http://lists.mysql.com/plusplus/8955

As new version 3.1.0 with fixes included is imminent, I think we could wait for it

Comment 6 Remi Collet 2010-09-04 14:10:08 UTC
Version 3.1.0 is available in repository.
