Question

I am running MySQL and I need to change the data type of certain columns from an enumeration to integer. However, there are a lot of columns. (If this exists) What is the syntax to alter all columns at the same time that are enumerations. Here is how I am updating a single column to make it integer data type:

ALTER TABLE table_name CHANGE column_name column_name INTEGER;

Answer 1

SHOW COLUMNS FROM WHERE TYPE LIKE "%enum%"

you could afterwards iterate through your result similar to the solution described here:
