This is for Mac  but must be same for other OS except the location of the preferences   The error we get when we try an unsafe DELETE operation    On the new window  uncheck the option Safe updates    Then close and reopen the connection  No need to restart the service   Now we are going to try the DELETE again with successful results     So what is all about this safe updates  It is not an evil thing  This is what MySql says about it   Using the --safe-updates Option     For beginners  a useful startup option is --safe-updates  or   --i-am-a-dummy  which has the same effect   It is helpful for cases when you might have issued a DELETE FROM tbl name statement but   forgotten the WHERE clause  Normally  such a statement deletes all   rows from the table  With --safe-updates  you can delete rows only by   specifying the key values that identify them  This helps prevent   accidents       When you use the --safe-updates option  mysql issues the following   statement when it connects to the MySQL server    SET sql safe updates 1  sql select limit 1000  sql max join size 1000000    It is safe to turn on this option while you deal with production database  Otherwise  you must be very careful not accidentally deleting important data

All that s needed is  Start a new query and run    SET SQL SAFE UPDATES   0    Then  Run the query that you were trying to run that wasn t previously working

It looks like your MySql session has the safe-updates option set  This means that you can t update or delete records without specifying a key  ex  primary key  in the where clause   Try   SET SQL SAFE UPDATES   0    Or you can modify your query to follow the rule  use primary key in where clause

No need to set SQL SAFE UPDATES to 0  I would really discourage it to do it that way  SAFE UPDATES is by default on for a REASON  You can drive a car without safety belts and other things if you know what I mean    Just add in the WHERE clause a KEY-value that matches everything like a primary-key comparing to 0  so instead of writing   UPDATE customers SET countryCode    USA      WHERE country    USA                 -- which gives the error  you just write   UPDATE customers SET countryCode    USA      WHERE  country    USA  AND customerNumber  lt  gt  0   -- Because customerNumber is a primary key you got no error 1175 any more    Now you can be assured every record is  ALWAYS  updated as you expect

I too got the same issue but when I off  safe updates   in Edit - gt  Preferences - gt  SQL Editor - gt  Safe Updates  still I use to face the error as  quot Error code 1175 disable safe mode quot   My solution for this error is just given the primary key to the table if not given and update the column using those primary key value   Eg  UPDATE  table name  SET Empty Column    Value   WHERE  primary key column name    value

If you are in a safe mode  you need to provide id in where clause  So something like this should work   UPDATE tablename SET columnname 1 where id gt 0

Since the question was answered and had nothing to do with safe updates  this might be the wrong place  I ll post just to add information   I tried to be a good citizen and modified the query to use a temp table of ids that would get updated   create temporary table ids   id int       select id from prime table where condition   true  update prime table set field1      where id in  select id from ids     Failure   Modified the update to   update prime table set field1      where id  lt  gt  0 and id in  select id from ids     That worked   Well golly -- if I am always adding where key  lt   0 to get around the safe update check  or even set SQL SAFE UPDATE 0  then I ve lost the  check  on my query   I might as well just turn off the option permanently   I suppose it makes deleting and updating a two step process instead of one    but if you type fast enough and stop thinking about the key being special but rather as just a nuisance

If you re having this problem in a stored procedure and you aren t able to use the key in the WHERE clause  you can solve this by declaring a variable that will hold the limit of the rows that should be updated and then use it in the update delete query  DELIMITER   CREATE PROCEDURE myProcedure   BEGIN     DECLARE the limit INT       SELECT COUNT    INTO the limit     FROM my table     WHERE my column IS NULL               UPDATE my table     SET my column   true     WHERE my column IS NULL     LIMIT the limit  END
