WHERE Keyword in SQL Server

In this post, The SQL WHERE keyword is used to select data conditionally, by adding it to already existing SQL SELECT query. The WHERE keyword can be used to select, update and delete data from table, but for now we will stick with conditionally retrieving data, as we already know how to use the SELECT keyword.

SELECT * FROM Customer
WHERE Country='India'

The following operators can be used in the WHERE commands
