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.

Making Column Labels More Friendly

Aliasing column labels give us the convenience of renaming a column label to something more readable. There is a tradeoff when naming columns to make them succinct results in reduced readability in subsequent daily use. In our Orders table, the item column contains the description of purchased products. Let’s see how to alias the item column to temporarily rename it for greater user-friendliness:

SELECT Item AS item_description FROM Orders

So, that’s all in this blog. I will meet you soon with next stuff .Have a nice day !!!
