SQL Comparison Operators Examples

The following is the list of Comparison operators with an example of each.

Equal to =

The SQL Equals Operator is the most used comparison item. It will display the records whose column value is exactly equal to the given expression.

For example, the following comparison operator query will find all the Customers present in the Customers table whose Occupation is exactly equal to Management.

SELECT [FirstName]
      ,[LastName]
      ,[YearlyIncome]
      ,[Education]
      ,[Occupation]
 FROM [Customer]
 WHERE [Occupation] = 'Management'
SQL Equal to = 1

Greater Than >

The SQL Greater than Operator will display the records whose column value is Greater than the given expression. For example, The following Server Greater than will find all the Customers present in the Customers table whose [Yearly Income] is Greater than 60000

SELECT [FirstName]
      ,[LastName]
      ,[YearlyIncome]
      ,[Education]
      ,[Occupation]
 FROM [Customer]
 WHERE [YearlyIncome] > 60000
Greater Than 2

Less Than <

The Less than Operator will display the records whose column value is Less than the given expression. The following Less than comparison Operators query will find all the Customers present in the Customers table whose [Yearly Income] is Less than 70000

SELECT [FirstName]
      ,[LastName]
      ,[YearlyIncome]
      ,[Education]
      ,[Occupation]
 FROM [Customer]
 WHERE [YearlyIncome] < 70000
Less Than 3

Greater Than or Equal to >=

It is used to will display the records whose column value is greater than or equal to the given expression. For example, The following Greater than or Equal to comparison operators in sql query will find all the Customers present in the Customers table whose [Yearly Income] is Greater than or equal to 60000

SELECT [FirstName]
      ,[LastName]
      ,[YearlyIncome]
      ,[Education]
      ,[Occupation]
 FROM [Customer]
 WHERE [YearlyIncome] >= 60000
SQL Comparison Operators 4

Less Than or Equal to <=

The SQL Less than or Equal will display the records whose column value is Less than or equal to the given expression.

For example, the following query will find all the Customers available in the Customers table whose [Yearly Income] is Less than or equal to 70000

SELECT [FirstName]
      ,[LastName]
      ,[YearlyIncome]
      ,[Education]
      ,[Occupation]
 FROM [Customer]
 WHERE [YearlyIncome] <= 70000
Less Than or Equal to 5

Not Equal to <>

It will display the records whose column value is not equal to the given expression.

For example, The following query will find all the Customers available in the Customers table whose [Yearly Income] is Not Equal to 60000. It means it will display all the records except [Yearly Income] to be Equal to 60000

-- SQL Server Comparison Operators Example
SELECT [FirstName]
      ,[LastName]
      ,[YearlyIncome]
      ,[Education]
      ,[Occupation]
 FROM [Customer]
 WHERE [YearlyIncome] <> 60000
Not Equal to <> 6

Not Equal To !=

The SQL Not Equal to operator is the same as <>. For example, The following Not Equal to operator query will find the Customers present in the Customers table whose [Yearly Income] is Not Equal to 60000.

SELECT [FirstName]
      ,[LastName]
      ,[YearlyIncome]
      ,[Education]
      ,[Occupation]
 FROM [Customer]
 WHERE [YearlyIncome] != 60000
