“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” is a fairly common issue that any coder will encounter. So, what are our options? Everything will be explained to you.
Why Does The Error “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” Occur?
You are attempting to keep updating one column in your table, but you encounter the following problem.
Two Simple Solutions For You
Method 1: Use The Primary Key
You must include your primary key in the query. If you use it without the primary key, you will encounter the above inaccuracy.
UPDATE customers SET country_code = ‘+91’ WHERE country = ‘India’; // It Will Give You Error
However, if you use the Primary Key, you will no longer encounter any errors. Customer_id is the primary key in Query.
UPDATE customers SET country_code = ‘+91’ WHERE (country = ‘INdia’ AND customer_id <> 0); // It will Run Successfully
We could now assure all website visitors that the issue is simple to resolve.
Method 2: Cet the SQL_SAFE_UPDATES = 0
We believe the SQL SAFE UPDATES is set, so you could not update and delete records without defining a primary key. To resolve this, set SQL SAFE UPDATES = 0. Run the SQL query.
SET SQL_SAFE_UPDATES = 0;
Then, execute your query. As an example, consider my query.
UPDATE tablename SET columnname=1;
This would run properly, and even though you want to restore SQL SAFE UPDATES to their original state, run the query first.
We could now confirm to users that the issue is simple to resolve.
