In SQL Server, the SELECT statement is used to retrieve data from one or more tables. The SELECT statement retrieves data from a table based on the specified conditions and returns the result set. The SELECT statement can be used with various clauses such as WHERE, GROUP BY, HAVING, ORDER BY, etc. to filter and sort the data.

The SELECT statement can also be used to retrieve data based on a specific ID using the WHERE clause. For example, if you have a table named “Customers” with columns “CustomerID”, “CustomerName”, “ContactName”, “Country”, and “City”, you can use the following query to retrieve data for a specific customer ID:

Sql Query
