Hello All,

Hope this post finds you in good health and spirit.

Structured Query Language, abbreviated as SQL, is a domain-specific language used in programming and designed for managing data held in a relational database management system, or for stream processing in a relational data stream management system.

An good developer must be familiar with a few commands in SQL because it is such a strong development tool. The SQL queries listed below are important for coding and optimization. Almost every system that interacts with a SQL database will be affected by each query in the SQL tutorial.

Data Manipulation Using AVG

Simple – an average of a given attribute. Average is also an aggregate function in SQL. The AVG() function computes the average of non-NULL values in a column. It ignores the null values.

SELECT AVG(Price)FROM Products;
