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

Just ALTER TABLE with the MODIFY command:

ALTER TABLE `table` MODIFY `price` DECIMAL(4,2)

This would allow for 2 decimals and 2 full numbers (up to 99.99). If you want 4 full numbers, use 6,2 instead (which would allow up to 9999.99).
