What is the method for comparing timestamps in SQL?

In SQL, comparison operators can be used to compare timestamps. Some commonly used comparison operators include:

1. Greater than (>): used to compare whether one timestamp is greater than another timestamp.
2. Less than (<): used to compare if one timestamp is smaller than another timestamp.
3. Greater than or equal to (>=): Used to compare whether one timestamp is greater than or equal to another timestamp.
4. Less than or equal to (<=): Used to compare if one timestamp is less than or equal to another timestamp.

For example, if you want to compare the sizes of two timestamps, timestamp1 and timestamp2, you can write it like this:

SELECT * FROM table_name
WHERE timestamp1 > timestamp2;

This will return the records from table_name table where the timestamp1 field is greater than the timestamp2 field.
