SQL Server Interview Question #41

What is the SELECT statement in SQL Server?

SELECT, Filtering, Sorting & Built-in Functions Mid-Level Intermediate

Detailed Explanation

SELECT retrieves data from one or more tables, views, table-valued functions, or derived result sets. A production query should normally request only the columns actually needed rather than using SELECT *.

Selecting fewer columns reduces unnecessary data transfer, can reduce memory and I/O requirements, and makes application contracts clearer.

Code Example

SELECT Id, Name, Price
FROM dbo.Products;
