What Is A SQL CHECK Constraint? In this informative video, we will cover the SQL CHECK constraint and its role in maintaining data accuracy within databases. We’ll explain what a CHECK constraint is and how it applies to specific columns or sets of columns in a table. By enforcing rules on the data entered, CHECK constraints help ensure that only valid information is stored, preventing errors before they occur.

We will also discuss the two main types of CHECK constraints: column constraints and table constraints. You’ll learn how these constraints can be used to validate data entries, such as ensuring that salaries fall within a specified range. Additionally, we’ll provide a practical example using an Employees table, demonstrating how to implement a CHECK constraint effectively.

This video is perfect for programmers and database administrators who want to enhance their understanding of data integrity and simplify their coding tasks. By the end, you’ll have a clearer grasp of how to utilize CHECK constraints to keep your database reliable and consistent.
