如何将时间戳从Oracle转换为Mysql

问题描述

我正在尝试将时间戳从Oracle转换为Mysql。我有一个数据文本文件，试图在MySQL数据库中加载数据，但出现SQL语法错误。请帮忙

LOAD DATA INFILE '/check/value.txt' INTO TABLE TEST FIELDS TERMINATED BY '|' (ID,@DATETIME) SET DATETIME = CONVERT_TZ(REPLACE(SUBSTRING_INDEX(@DATETIME,'-',3),"T"," "),"-07:00","+00:00");

时间戳示例-2020-10-07T05：21：05-7：00。

下面是错误

 ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SET DATETIME = CONVERT_TZ(REPLACE(SUBSTRING_INDEX(@DATETIME,"+00:00")' 

解决方法

您可以尝试以下方法：

SELECT CONVERT_TZ(REPLACE(SUBSTRING_INDEX("2020-10-07T05:21:05-7:00",'-',3),"T"," "),"-07:00","+00:00");

,

SET @time := '2020-10-07T05:21:05-7:00';
SELECT CONVERT_TZ(STR_TO_DATE( @time,'%Y-%m-%dT%H:%i:%s'),-- datetime only
                  REGEXP_SUBSTR(@time,'[\+\-][0-9]{1,2}:[0-9]{2}$'),-- timeshift only
                  '+00:00') AS datetime_GMT;
