lower_case_table_names=0 沒毛病

最近發(fā)現(xiàn)遇到很多事，明明知道是自己不對(duì)的，還要求別人來(lái)做出改變，好奇怪~~

靜靜的寫個(gè)小文檔還是很好的~~~

mysql> show tables;
略
| t_txn_net                          |         ##這個(gè)表是存在的
| t_txn_pmc_breaker                  |
| t_txn_regedit                      |
| t_workday_pgm                      |
| t_workday_set                      |
+------------------------------------+
142 rows in set (0.00 sec)

mysql> select * from t_txn_neT;      ###查詢表不存在
ERROR 1146 (42S02): Table 'upp.t_txn_neT' doesn't exist
mysql> 
mysql> 
mysql> show variables like 'lower_case_table_names';     ##區(qū)分大小寫，這個(gè)沒毛病
+------------------------+-------+
| Variable_name          | Value |
+------------------------+-------+
| lower_case_table_names | 0     |
+------------------------+-------+
1 row in set (0.00 sec)

DBA總是有辦法的。
操作步驟如下：
1、關(guān)庫(kù)
shutdown;
2、修改參數(shù)
vi my.cnf
lower_case_table_names  = 1  ##不區(qū)分大小寫
3、啟庫(kù)
mysqld_safe --defaults-file=/etc/my.cnf &
4、再次查詢，OK
mysql> select * from t_txn_neT;
Empty set (0.00 sec)
5、查看小寫表名 value=1
mysql> show variables like 'lower%';
+------------------------+-------+
| Variable_name          | Value |
+------------------------+-------+
| lower_case_file_system | OFF   |
| lower_case_table_names | 1     |
+------------------------+-------+
2 rows in set (0.01 sec)
