my database:
===========
where i download the database:
---------------------------------
for MaNGOS Two (WoTLK)
git clone [url]https://github.com/mangostwo/database[/url]


here shows how I imported the database:
----------------------------------------
cd the folder "mangos"
mysql -u root -p
set names utf8;

#create database:
create database characters;
create database mangos;
create database realmd;
create database scriptdev2;

#import the structure of db:
use characters;
source Server/sql/characters.sql;
use realmd;
source Server/sql/realmd.sql;
use mangos;
source Server/sql/mangos.sql;

#import MANGOS:
use mangos;
source database/_tools/full_db.sql;

#import SCRIPT-DB:
use mangos;
source server/src/bindings/sql/mangos_scriptname_clear.sql;
source server/src/bindings/sql/mangos_scriptname_full.sql;
use scriptdev2;
source server/src/bindings/sql/scriptdev2_create_structure_mysql.sql;
source server/src/bindings/sql/scriptdev2_script_full.sql;

some updates:
|mangos folder\Server\sql\updates -+
| |archive
| |characters -+
| | |01_characters_random_battleground.sql
| |
| |mangos -+
| | |01_mangos_creature_template.sql
| | |02_mangos_creature_classlevels.sql
| |
| |realmd -+
| |void

i updated the three *.sql above,i checked the "archive" folder,and i found that all of the stuffs in there were imported in my database already ,so i didnt use them.

this is the version of my database(mangos.db_version):
UDB 0.12.2 (406) for MaNGOS 12444 with SD2 SQL for rev. 2857

so,what's the fault?
i guest it was the issue of database,but i dont know how to fix it . can you help?
