PostgreSQL - DATES

While working with PostgreSQL Date datatypes, it is essential to know about the dates format when performing different operations on a database. Please note that, the datatype of column must be chosen while creating a new table in the database.

The different data types available in PostgreSQL for storing a date or a date/time value are mentioned below:

Example: Create a table with date datatype

The below mentioned statement creates a table called Employee which contains five columns: EmpID, Name, City, Age and Date_of_Joining.

CREATE TABLE Employee (
  EmpID INT NOT NULL,
  Name VARCHAR(255) NOT NULL,
  City VARCHAR(100),
  Age INT,
  Date_of_Joining DATE
);

This will create a empty table named Employee containing five columns.

Example: Working with date datatype

Consider a database table called Employee with the following records:

To fetch data of all employees present in the Employee table who joined the organization on '2019-05-25', the query is:

SELECT * FROM Employee
WHERE Date_of_Joining = '2019-05-25';

This will produce the result as shown below:
