一、運行Load data local infile命令時:
mysql> LOAD DATA LOCAL INFILE '/path/file' INTO TABLE tablename;1
出現:
ERROR 1148 (42000): The used command is not allowed with this MySQL version
這是因為:
服務器端,local_infile默認開啟;客戶端,local_infile默認關閉,因此用的時候需要打開。
服務器端,local_infile默認開啟;客戶端,local_infile默認關閉,因此用的時候需要打開。
On the server side:
The local_infile system variable controls server-side LOCAL capability. Depending on the local_infile setting, the server refuses or permits local data loading by clients that have LOCAL enabled on the client side. By default, local_infile is enabled.
On the client side:
For the mysql client, local data loading is disabled by default. To disable or enable it explicitly, use the –local-infile=0 or –local-infile[=1] option.
該怎么辦呢?
可以:
mysql> show global varaiables like 'local_infile';1
出現:
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| local_infile | OFF |
+---------------+-------+
1 row in set (0.00 sec)123456
| Variable_name | Value |
+---------------+-------+
| local_infile | OFF |
+---------------+-------+
1 row in set (0.00 sec)123456
可以這么做:
mysql> set global local_infile = 'ON';1
local_infile其實是bool變量,但這里用ON。
然后可以看到:
然后可以看到:
mysql> show global variables like 'local_infile';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| local_infile | ON |
+---------------+-------+
1 row in set (0.00 sec)1234567
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| local_infile | ON |
+---------------+-------+
1 row in set (0.00 sec)1234567
然后再試試Load data,本人仍舊出錯還是:
ERROR 1148 (42000): The used command is not allowed with this MySQL version1
因而退出mysql,執行quit或exit,然后用如下命令登錄mysql:
$ mysql --local-infile=1 -u root -p1
然后就可以順利Load data infile了。

二、在做mysql 大批量導出數據的時候,所遇到的問題如下:
ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement
mysql 默認對導出的目錄有權限限制,也就是說使用命令行進行導出的時候,需要指定目錄進行操作;
解決方法:
1. 查詢mysql 的secure_file_priv 值配置的是什么,使用命令行:
show global variables like '%secure%';
(我這里的配置是 secure_file_priv = /var/lib/mysql-files/)
2. 使用 into outfile 開始導出:(因為secure_file_priv配置的關系,所以必須導出到 /var/lib/mysql-files/目錄下)
select * from table_name where a = 'test'
into outfile '/var/lib/mysql-files/test.txt' FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n';
into outfile '/var/lib/mysql-files/test.txt' FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n';
3.所用的幾個關鍵字:
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY ' " ' LINES TERMINATED BY '\n';
(因為導出的數據會出現一些亂碼或者特殊字符,所以使用以上關鍵字進行轉義)
