mysql SELECT…十进制是整数

Question

I have a table which has a DECIMAL(4,2) column. It has values like 1.0, 1.1, 1.2, 2.0, 3.0, 3.1 .

How can I retrieve values that are only whole numbers?

I am doing SELECT * FROM table WHERE field LIKE '%.0'; but I am not sure if there's a better way to handle the numbers.

Answer 1

你可以用

SELECT * FROM table WHERE field = floor(field);
