MySQL Workbench: Error Code: 1175 [How to Solve]

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. You are using secure update mode, and you try to update a table that uses key columns without where. To disable safe mode, in preferences – & gt; Switch this option in the SQL editor and reconnect.

Solution: it can be solved with one statement.

SET SQL_SAFE_UPDATES = 0;

After executing the statement, execute the update operation again.

[Solved] Daily further: database error: unknown column ‘model’ in ‘field list‘

  If you encounter this problem today, record that you have created this’ model ‘field in the database and used querywrapper to initialize the query,   And then I reported this mistake,     Then I go to the database to query with SQL statements executed by the system;   It turned out that it was still a mistake   1054 – Unknown column ‘model’ in ‘field list’   ,
After that, use “*”   To query can directly find the data;   The field “model” also exists,   I don’t know what this is,   But locate the problem, start to modify the field. Then there is no problem
Other tables I created have the ‘model’ field, but this problem does not occur
But this is still a question,   After reading the explanation of other blogs, I found that I didn’t have the answer I wanted

Hope to have big guys see trouble to teach younger brother, also hope in the future I can give myself a direct answer~

Then I go to the database and query with the SQL statement executed by the system

It turned out to be a mistake   1054 – Unknown column ‘model’ in ‘field list’

After that, use “*”   To query, you can directly find the data. This field “model” also exists,

Other tables I created have the ‘model’ field, but they can be found directly
