查詢有關SQL關於出口，結果到Excel

Question

在此查詢我試圖將結果導出爲CSV ...但我得到的錯誤作爲

error:----Every derived table must have its own alias

SELECT * INTO OUTFILE "c:/mydata.csv" 
FROM (SELECT e.server,e.token,e.datetime,e.workstation,f.surname,f.forename,f.token 
FROM statistic e, USER f 
WHERE e.token=f.token); 

Answer 1

嘗試定義您的子查詢的別名：

SELECT * INTO OUTFILE "c:/mydata.csv" 
FROM (SELECT e.server,e.token as stat_token,e.datetime,e.workstation, 
      f.surname,f.forename,f.token as user_token 
     FROM statistic e, 
     USER f 
     WHERE e.token=f.token) as server_statistics;
