Error (Error Code: 1175) during executing update command on table using MySQL Workbench 5.2

问题

I'm using MySQL Server5.5 in which MySQL Workbench 5.2 CE is included. I'm using MySQL Workbench 5.2 . I have a table named user in DB. I executed the following command on SQL Editor at MySQL Workbench:

UPDATE user SET email = 'abc@yahoo.com' WHERE email='ripon.wasim@yahoo.com';

But unfortunately I got the following error:

Error Code: 1175. You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column To disable safe mode, toggle the option in Preferences -> SQL Editor -> Query Editor and reconnect.

What's the wrong? Help is highly appreciated.

回答1:

Every time you encountered that kind of error when trying to update rows in mysql, It’s because you tried to update a table without a WHERE that uses a KEY column.

You can fix it using,

SET SQL_SAFE_UPDATES=0;
UPDATE user SET email = 'abc@yahoo.com' WHERE email='ripon.wasim@yahoo.com';

or in the WorkBench

• Edit -> Preferences -> SQL Queries
• Uncheck Forbid UPDATE and DELETE statements without a WHERE clause (safe updates)
• Query --> Reconnect to Server

回答2:

It is more correct to deactivate and reactivate

SET SQL_SAFE_UPDATES=0; --disable
UPDATE user SET email = 'abc@yahoo.com' WHERE email='ripon.wasim@yahoo.com';
SET SQL_SAFE_UPDATES=1; --enable
