PostgreSQL VALUES Keyword

The PostgreSQL VALUES keyword is used to specify the values of an PostgreSQL INSERT INTO statement. There are two ways of using VALUES keyword which are mentioned below:

Syntax

The below syntax specifies column names and respective values to be inserted.

INSERT INTO table_name (column1, column2, column3, ...)
VALUES (value1, value2, value3, ...);

The below syntax specifies values only. Therefore, it is essential to specify values in the same order as the columns in the table.

INSERT INTO table_name 
VALUES (value1, value2, value3, ...);

Example:

Consider a database containing a table called Employee with the following records:

• Using below query, two new records are added in the Employee table:

  INSERT INTO Employee (EmpID, Name, City, Age, Salary)
  VALUES (7, 'Suresh', 'Mumbai', 29, 2900);
  INSERT INTO Employee 
  VALUES (8, 'Zayne', 'Oslo', 31, 3400);
  
  -- see the result
  SELECT * from Employee
  

  
  

  Now the Employee table will contain following records:

  EmpID	Name	City	Age	Salary
  1	John	London	25	3000
  2	Marry	New York	24	2750
  3	Jo	Paris	27	2800
  4	Kim	Amsterdam	30	3100
  5	Ramesh	New Delhi	28	3000
  6	Huang	Beijing	28	2800
  7	Suresh	Mumbai	29	2900
  8	Zayne	Oslo	31	3400

• Insert Data Only in Specified Columns: To insert data in specified columns, it is necessary to specify column names. See the example below:

  INSERT INTO Employee (EmpID, Name, Age)
  VALUES (7, 'Suresh', 29);
  
  -- see the result
  SELECT * from Employee
  

  
  

  Now the Employee table will contain following records:

  EmpID	Name	City	Age	Salary
  1	John	London	25	3000
  2	Marry	New York	24	2750
  3	Jo	Paris	27	2800
  4	Kim	Amsterdam	30	3100
  5	Ramesh	New Delhi	28	3000
  6	Huang	Beijing	28	2800
  7	Suresh		29
