MySQL error code 1175 during UPDATE in MySQL

If you are working with the MySQL database and you want to update or delete any data row in the MySQL database table without using a WHERE clause. And for this, you run the query, then you got 1175 during UPDATE in MySQL error.

MySQL error code 1175 occurs when you try to update or delete a table column that is part of a unique index or primary key. The error message typically reads: “ERROR 1175 (HY000): You are using safe update mode and you tried to update a table without a WHERE that uses a KEY column.”.

When you have safe mode enabled, MySQL requires that you specify a WHERE clause that includes a column that is part of an index or primary key. This ensures that you only update or delete the rows that you intended to modify.

How to fix MySQL ERROR code 1175 during Update in MySQL

There are several ways to resolve the MySQL error code 1175. Here are some solutions you can try:

• Method 1: Disable safe mode
• Method 2: Use a WHERE clause

Method 1: Disable safe mode

If your sql_safe_updates is turned ON, so an UPDATE or DELETE statement without a WHERE clause will cause the error 1175.

Here’s an example UPDATE a statement that causes the error:

mysql> UPDATE posts SET title = "testtt";

ERROR 1175 (HY000): You are using safe update mode and you tried 
to update a table without a WHERE that uses a KEY column. 

If you don’t need safe mode, you can disable it to update the table without the WHERE clause. To do this, you can use the command:

SET SQL_SAFE_UPDATES=0;

You should now be able to execute UPDATE or DELETE statement without the WHERE clause.

If you want to enable safe update mode again, To do this, you can use the command:

SET SQL_SAFE_UPDATES = 1;

Method 2: Use a WHERE clause

The recommended solution is to use a WHERE clause in your update statement that includes the indexed column. For example, if you have a table named “posts” with a primary key column named “id”, you can update a row using the following command:

UPDATE posts SET title= 'hello world' WHERE id = 1;

This will update the title column for the row with id = 1.

Always keep in mind that updating or deleting a table without a WHERE clause will result in changes being applied to all rows in the table. This can have unintended and potentially disastrous consequences, such as permanently deleting important data.

To prevent such accidents, MySQL offers a “safe update mode” that is designed to prevent unintentional changes to the database. Enabling this mode ensures that you always specify a WHERE clause that includes a column that is part of an index or primary key before modifying or deleting rows. This can help prevent accidental data loss and maintain data integrity in your database.

Conclusion

MySQL error code 1175 can be frustrating when you’re trying to update or delete a table column. However, it is a safety feature designed to prevent accidental modifications of rows in a table. By using the solutions outlined above, you can easily resolve this error and update your table without any issues. Remember to always use safe mode when updating or deleting rows to avoid any unintentional data modifications in your database.
