Suppose you get a chance to write a DATE comparison in the WHERE clause. Here’re brilliant ideas on how to use it in the WHERE clause for your quick reference.
For this demo, I chose three examples. This logic you can follow for comparing the DATEs in your project.
SQL Query Compares Dates using ‘>’ Greater than
SELECT * FROM table WHERE purchdate > '2002-10-01';
The syntax for DATE is
datecolumn > ‘XXXX-XX-XX’
- Always you need to give date in quotes.
- You can use <, >, = in DATE comparisons.
SQL Query Compare Dates using ‘<‘ Less than
WHERE purchdate < '2002-10-10';
SQL Query Using DATE ‘=’ Equal to
WHERE purchdate = '2020-04-19;
Organizations need speed deployment at scale. AWS provides a service called code pipeline, which is a four-step process explained here.
Date conversion in SQL simplifies your work, and you will get the desired result. These two functions most people use in the production code.
