Why do we use sql limitations? Which constraints can we use while making a database in sql?

Answer Posted / Bablu Kumar

SQL limitations, such as constraints and data types, help ensure the integrity and consistency of the data stored in a database. They prevent invalid or inconsistent data from being entered and maintained within the database. Some constraints include NOT NULL, UNIQUE, PRIMARY KEY, FOREIGN KEY, CHECK, DEFAULT, and INDEX. These can be used to enforce rules on columns, tables, and relationships between tables.
