postgre create table with check Create Table With Check PostgreSQL

In PostgreSQL, you can create a table with a check constraint to enforce specific rules on data entered into the table. When defining the table using the CREATE TABLE statement, you can include a CHECK constraint to specify conditions that must be met for data to be inserted or updated. For example, you can restrict values in a column to be within a certain range or meet a specific condition. This ensures data integrity by preventing invalid or undesirable data from being stored in the table, enhancing the reliability and consistency of your database.
