Mysql Vs Mssql Key Differences You Need To Know How can you connect to mysql from the command line in a mac? (i.e. show me the code) i'm doing a php sql tutorial, but it starts by assuming you're already in mysql. If your table has a pk all rows should be distinct by definition. if you are trying to just select distinct field1 but somehow return all other columns what should happen for those columns that have more than one value for a particular field1 value? you would need to use group by and some sort of aggregation on the other columns for example. 36 mysql workbench if you want to avoid writing sql, you can also do it in mysql workbench by right clicking on the table, choose "alter table " in the menu. when the table structure view opens, go to tab "options" (on the lower bottom of the view), and set "auto increment" field to the value of the next autoincrement number. Why oh why can i not connect to mysql? mysql u root ptest101 h xxx.xxx.xxx.xxx error 1130 (hy000): host 'xxx.xxx.xxx.xxx' is not allowed to connect to this mysql server in my.cnf i have the below # instead of skip networking the default is now to listen only on # localhost which is more compatible and is not less secure.

And change the root password: mysql> flush privileges; mysql> alter user 'root'@'localhost' identified with mysql native password by 'mynewpass'; revert back the mysql configuration file changes by removing skip grant tables line or commenting it with a # (hash). finally restart the mysql service and you are good to go. I have a mysql user, whom i want to grant all the read permission on a db schema. one way is this : grant select, show view on test.* to 'readuser'@'%'; is there a way to group all read operatio. Not supported on grant tables. * from mysql 8.0.22, the group replication ip whitelist system variable is deprecated, and the system variable group replication ip allowlist has been added to replace it. the system variable works in the same way as before, only the terminology has changed. for both system variables, the default value is automatic. I accidentally enabled only full group by mode like this: set sql mode = 'only full group by'; how do i disable it?.
