匯出CSV表，使用excel或WPS開啟後發現數據超過15位的後面全變成了00000；

原來使用的匯出語句：

SELECT * INTO OUTFILE '/tmp/test.csv'   FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n' FROM test.test;

修改後的匯出語句：關鍵點在於將enclosed by 後的分隔符從雙引號變成\t；

SELECT * INTO OUTFILE '/tmp/test.csv'   FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '\t' LINES TERMINATED BY '\n' FROM test.test;

再開啟後不再有低位變成00000的現象。
