SQL Tutorial will guide us now IN SQL keyword, there are two uses of the SQL IN keyword, and this SQL Tutorial section introduces the one that is related to the SQL WHERE clause. When used in this context, we know exactly the value of the returned values we want to see for at least one of the columns. The syntax for using the SQL IN keyword is as follows:

Syntax for SQL IN Keyword

SELECT "column_name"
FROM "table_name"
WHERE "column_name" IN ('value1', 'value2', ...)

The number of values in the parenthesis can be one or more as required, with each values separated by comma. Values can be numerical or characters or both. If there is only one value inside the parenthesis, this commend is equivalent to

WHERE "column_name" = 'value1'

For example, we may wish to select all records for the Employee Creston and Bobbi in the table of Employees.
Table: Employees

FirstName	LastName	Email	DOB	Phone
