MySQL Error Code: 1175. safe update mode update a table without a WHERE

Dung Do Tien Nov 08 2021 134

Hello Guys,

I have a MySQL server and I have created a impression table.  I want to update the value of numberofvisit column to 0:

update impresssion set numerofvisit = 0

I ran the above command and I got an exception Error Code: 1175.  safe update mode updates a table without a WHERE.

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 and reconnect.

Error Code: 1175. safe update mode update a table without a WHERE

My table has 12k records. I don't know why it's not allowing me to update it.

Thanks for any suggestions.

    You can use the command below to help change the setting default in the MySQL database: 

    Like this:

    -- disable safe update mode
SET SQL_SAFE_UPDATES=0;
-- execute update statement
UPDATE table SET column='value';
-- enable safe update mode
SET SQL_SAFE_UPDATES=1;

    FOR an example:

    -- disable safe update mode
SET SQL_SAFE_UPDATES=0;
-- execute update statement
UPDATE impresssion SET numerofvisit = 0
-- enable safe update mode
SET SQL_SAFE_UPDATES=1;

    I hope it works for you.
