MySQL - How do I update the decimal column to allow more digits?

Question

I\'m a beginner in MySQL, and I accidentally created a table with a column named

(price decimal(2,2));

It needs to be decimal(4,2)

Answer 1

It's not a matter of 'UPDATE' it's a matter of changing your table's structure. For that, use ALTER TABLE with MODIFY clause:

ALTER TABLE YourTableName MODIFY COLUMN price DECIMAL(4,2);
