MySQL - SELECT INTO OUTFILE，带有 UNION

  • 772

是否可以发出多个选择查询，其结果集通过联合组合到同一个输出文件中？

我正在尝试做的，但没有工作：

(SELECT email FROM table WHERE createdate >= date_sub(now(), interval 1 year))
UNION DISTINCT
(SELECT email FROM table WHERE createdate < date_sub(now(), interval 1 year) AND email not like '%@gmail.com')
INTO OUTFILE '/tmp/emailDump.txt' FIELDS TERMINATED BY "," LINES TERMINATED BY "\n";
mysql union

    试试这个

    SELECT * FROM
((SELECT email FROM table WHERE createdate >= date_sub(now(), interval 1 year))
UNION DISTINCT
(SELECT email FROM table WHERE createdate < date_sub(now(), interval 1 year) AND email not like '%@gmail.com')) A
INTO OUTFILE '/tmp/emailDump.txt' FIELDS TERMINATED BY "," LINES TERMINATED BY "\n";
