Question

我有一个简单的查询，它从MySQL表中选择列并将其写入csv文件。

 (select 'tempid', 'region', 'puma')
 union all
 select * from (select tempid, region, puma_2000 from tableA order by tempid  limit 
 4000000) a
  into outfile 'c:/models/output.csv'
 FIELDS TERMINATED BY ','
  optionally ENCLOSED BY '"'
 LINES TERMINATED BY '\r\n';

它给了我＆＃34;错误1064.您的SQL语法出错。＆＃34;。我尝试了一些改动，但似乎没有任何效果。我使用的MySQL版本是5.5。你在查询中看到一个明显的错误吗？

Answer 1

在行中：

select * from (select tempid, region, puma_2000 from tableA order by tempid,  limit

尝试在tempid之后和限制之前删除逗号：

select * from (select tempid, region, puma_2000 from tableA order by tempid limit

MySQL：将表写入csv文件
