Insert Data and Return Rows with RETURNING in PostgreSQL and OUTPUT in SQL Server

Using RETURNING in PostgreSQL and OUTPUT in SQL Server

Write a SQL query to insert data and return the inserted rows, using RETURNING in PostgreSQL and OUTPUT in SQL Server.

Solution:

-- PostgreSQL
INSERT INTO Employees (Name, Salary)
VALUES ('John Doe', 60000)
RETURNING EmployeeID, Name, Salary;

-- SQL Server
INSERT INTO Employees (Name, Salary)
OUTPUT INSERTED.EmployeeID, INSERTED.Name, INSERTED.Salary
VALUES ('John Doe', 60000);

Explanation:

• Purpose of the Query :
• The goal is to demonstrate how to return inserted rows using platform-specific syntax.
• Key Components :
• RETURNING (PostgreSQL): Returns inserted rows directly.
• OUTPUT (SQL Server): Captures inserted rows using the INSERTED virtual table.
• Why Compare Insertion Results?:
• Returning inserted rows simplifies confirmation and further processing.
• Understanding these differences ensures efficient data handling.
• Real-World Application :
• In transactional systems, returning inserted rows supports real-time updates.

Additional Notes:

• Use RETURNING in PostgreSQL and OUTPUT in SQL Server for compatibility.
• Test queries on all target platforms to ensure consistent results.
• Important Considerations:
• Avoid unnecessary use of these features for performance reasons.
