![]() ![]() This post will run through how you can effectively work with dates in SQL, resolve your issue quickly, and get back to bed. In Javascript you’ve got Moment, but parsing dates in SQL is a bit more complex. Nobody likes dates, especially programmers, but they’re a critical part of pretty much every application. It turns out migrating from Redshift to Bigquery was not “as easy as 123” and your DBA switched all of your timestamps to unix time. But slowly, your sweet dream turns into a nightmare: all of the queries you wrote earlier in the day are parsing dates wrong, your app is down, and your boss is angry. The timestamp data type storage size is 8 bytes.It’s 3AM, and you’re sleeping soundly in your room.A low value of the timestamp data type is 4713 BC, and a higher value in PostgreSQL is 294276 AD.Timestamp data storage size is 8 bytes to store data in the database timestamp data type is beneficial and important in PostgreSQL to store the data’s date and time data.The timestamp is not a time zone data type it only stores time and date in some cases, if the time zone of the server changes, it will not affect on actual data that we have stored in the database. ![]() If we want to use the current date and time, we need to use a current timestamp function in PostgreSQL. The current timestamp function selects the current date and time in PostgreSQL.The below figure shows an example of a time of day function in PostgreSQL. You can use the time of day function to select the current day, date, and time format, along with the corresponding timezone.The below figure shows the example of now function in PostgreSQL: Now the function is more important to select the current date and time in PostgreSQL. If we want to use the current date and time, we need to use a now function in PostgreSQL. Now the function selects the current date and time in PostgreSQL.Below is the function of the timestamp data type as follows.Timestamp data type is divided into types with and without a time zone.If we want to use a without a time zone, we need to use a timestamp data type if we’re going to use a time zone, we need to use a timestamp data type. We can use a timestamp data type with and without a time zone.How does Timestamp Data Type work in PostgreSQL? The current timestamp function is more important to select the current date and time in PostgreSQL. If we want to use the current date and time, we have to use a current timestamp function in PostgreSQL. Current timestamp: This function selects the current date and time in PostgreSQL.If we have used only the date, then it will display a date and time. Date and time: We can use any date and time to display the timestamp format. ![]() ![]() If we want to use the current date and time, we have used a now function in PostgreSQL.
