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.

Displaying Foreign Keys

Foreign keys link one table to another – they are attributes in one table which refer to the primary key of another table.

SELECT * FROM Sys.Objects WHERE Type='f'

Primary, Unique, and Foreign are part of the constraints in SQL. Constraints are essential to the scalability, compliance, and sincerity of the data. Constraints implement particular rules, assuring the data adheres to the conditions outlined. So, that’s all in this blog. I will meet you soon with next stuff .Have a nice day !!!
