Preface
I found an error at work today. When importing the data table locally, I always reported an error:
[Err] 1294 - Invalid ON UPDATE clause for '字段名' column
The data table field where the error was reported:
`字段名` datetime DEFAULT NULL ON UPDATE CURRENT_TIMESTAMP
A colleague said that he could successfully import the same sql file. I guess it may be a problem with the database version. My colleague's version is 5.6. I checked the local database version and it is 5.5.53. After checking online, it turned out to be a version problem. 5.5 and 5.6 have different behaviors of TIMESTEMP. Versions before 5.6.5 do not support multiple CURRENT_TIMESTAMP default values.
Since the local integrated environment is phpStudy 2016, there is no option to upgrade the MySQL version, so I upgraded it myself.
Download the higher version of MySQL from the official website:
Official website: https://dev.mysql.com/downloads/file/?id=467269
Baidu Cloud Disk address: https://pan.baidu.com/s/1mi4UHtA
The selected version is 5.7.17 (later I discovered that the installation, system table fields, etc. of version 5.7 are different from the previous version) ).
Steps:
1. Back up the original MySQL installation directory in phpStudy
2. Extract the downloaded MySQL compressed file to the MySQL directory under phpStudy, and copy my-default. ini, renamed to my.ini.
Open my.ini, find #basedir and edit:
basedir=D:/phpStudy/MySQL datadir=D:/phpStudy/MySQL/data
3. Add the MySQL installation path to the system environment variable
4. Enter the MySQL bin under cmd Directory (mine is D:/phpStudy/MySQL/bin), execute:
mysqld --initialize
Initialize database
5. Install service:
mysqld -install
Start service:
net start MySQL
6. Log in to MySQL at this time and an error message is reported:
C:\Users\dell>mysql -uroot -p Enter password: **** ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
Try to change the root user password:
Open my.ini, find [mysqld], and add below:
skip-grant-tables
At this time, use the root account and press Enter in the password field to log in.
Change password:
mysql>update mysql.user set authentication_string=password('new_password') where user='root' and Host ='localhost' mysql> ALTER USER USER() IDENTIFIED BY 'news_password';
Refresh permissions:
FLUSH PRIVILEGES;
Comment out the
skip-grant-tables
just added in my.ini and log in again.
Check the mySQL version at this time:
mysql> select version(); +-----------+ | version() | +-----------+ | 5.7.17 | +-----------+
