How do I compare timestamps in SQL?

How do I compare timestamps in SQL?

You can compare timestamps in SQL using comparison operators like =, <, >, <=, and >=. For example, to find records where a timestamp is greater than a specific date, you can use: SELECT * FROM table WHERE timestamp_column > '2023-01-01 00:00:00';

What if I want to compare two timestamp columns?

You can compare two timestamp columns directly. For instance: SELECT * FROM table WHERE timestamp_column1 > timestamp_column2; This will return rows where the first timestamp is later than the second.

Can I use functions to manipulate timestamps before comparing?

Yes, you can use functions like DATEADD, DATEDIFF, or EXTRACT to manipulate timestamps. For example, to compare a timestamp with a date 7 days ago, you could use: SELECT * FROM table WHERE timestamp_column > DATEADD(day, -7, GETDATE());
