Introduction to PostgreSQL LAG() function:

#PostgreSQL LAG() function provides access to a row that comes before the current row at a specified physical offset. In other words, from the current row the LAG() function can access data of the previous row, or the row before the previous row, and so on.

The LAG() function will be very useful for comparing the values of the current and the previous row.

What is the difference between #LATERAL JOIN and a subquery in PostgreSQL

What is a #LATERAL join?
The LATERAL key word can precede a sub-SELECT FROM item. This allows the sub-SELECT to refer to columns of FROM items that appear before it in the FROM list. (Without LATERAL, each sub-SELECT is evaluated independently and so cannot cross-reference any other FROM item.)

🔗 [ https://stackoverflow.com/questions/28550679/what-is-the-difference-between-lateral-join-and-a-subquery-in-postgresql ]


The following relational database systems support the LATERAL JOIN syntax:
- #Oracle since 12c
- #PostgreSQL since 9.3
- #MySQL since 8.0.14

#Book 📚📕

Coding and testing are generally considered separate areas of expertise. In this practical book, Java expert Scott Oaks takes the approach that anyone who works with Java should be adept at understanding how code behaves in the Java Virtual Machine—including the tunings likely to help performance. This updated second edition helps you gain in-depth knowledge of Java application performance using both the JVM and the Java platform.
