system_mysql_db_refs.test

这是linux下运行的mysql软件包,可用于linux 下安装 php + mysql + apach 的网络配置

#
# This test must examine integrity of current system database

set @name="This is a very long string, that mustn't find room in a system field like Table_name. Thus it should be cut by the actual size of the field. So we can use this string to find out the actual length of the field and to use it in any compare queries";

# If this part is wrong, most likely you've done wrong modification of system database "mysql"
