如何导出/导入某些行？

Question

我的数据库中有这样一个表（用于游戏）：

 id   name   playcount
---- ------ -----------
 1    game#1  17
 2    game#2  22

等，字段playcount具有属性DEFAULT 0; 所以，我想通过导出除playcount之外的所有字段来重新创建这个数据库。

我该怎么做？一个phpmyadmin解决方案没问题。谢谢！

您可以对此使用INTO OUTFILE，以生成CSV格式

SELECT  id, name, 0 AS playcount
        INTO OUTFILE 'backup.txt'                       -- this is the location
        FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
        LINES TERMINATED BY '\n'
FROM TableName;

要重新加载文件，请使用LOAD DATA INFILE Syntax

LOAD DATA INFILE 'backup.txt'
INTO TABLE TableName
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\n';
