MySQL constraints are used to limit or restrict the type of data that can be entered into a table, ensuring data integrity and consistency. To check the constraints applied to a table in MySQL, you can use the `SHOW CREATE TABLE` command followed by the table name. This command will display the table’s definition, including any constraints that have been defined.
Constraints play a crucial role in maintaining the integrity of data in a database. They help to prevent invalid or inconsistent data from being entered, which can lead to errors and data corruption. By using constraints, you can ensure that the data stored in your tables is accurate and reliable.
