MySQL Workbench Error 1175 Even With a “Where” Statement

Question

I am running MySQL Workbench 6.3.8 b1228 CE (64-bit) in \"safe update mode\". I am trying to run a query with a \"WHERE\" statement, but it still returns \"Erro

Answer 1

maybe is a very simple error. Try delete the row from the user interface. see the attached images.

Answer 2

As Arnolio mentions in a comment,

The important part of the error is : "...without a WHERE that uses a KEY column". So i have to ask is the email column a key column?

I wasn't focused on the KEY portion, and my email column wasn't a KEY, which caused the error. Thanks, Arnolio!

Answer 3

In Sql by default safe options is enabled which restricts the user from deleting or updating the data in table using inappropriate key.To turn of the safe update go to

edit->preferences->sql editor and uncheck the safe update check box at the bottom of the preference window or even you can delete or update referencing the primary key.

For Example: Let us consider we have table called user_details with four fields(name, number, email ,address) where name is the primary key. So your delete statement would look like this

Delete from user_details where name="xxx";

Note: Reconnect to the database after safe update is turned off. Even you can restart the server but reconnect itself works fine.

Hope this solves your issue.

Answer 4

Consider:

update
    civicrm_address
set
    geo_code_1 = 99999
and
    id is not null

This throws the same error but,

update
    civicrm_address
set
    geo_code_1 = 99999
and
    id <> 0

is successful

Why doesn't the first one work?
