SQL Less Than Comparison Operator

The SQL Less Than comparison operator (<) is used to compare two values.  It returns TRUE if the first value is less than the second.  If the second is less, it returns FALSE. 

You can also test for Less than or equal to by using <=.  

Here are a couple of examples: 

10 < 5FALSE
5 < 20TRUE
10 < 10FALSE
SELECT ProductNumber, Name, ListPrice From Production.Product Where ListPrice < 100 
SELECT ProductNumber, Name, ListPrice 
From Production.Product 
Where ListPrice < 100

SQL Less Than with Other Types 

You can use the Less than comparison with other data type, such as String and DateTime. 

Here we’re returning products modified before February 15th, 2014. 

SELECT ProductNumber, Name, ListPrice, ModifiedDate From Production.Product WHERE ModifiedDate < '2014-02-15' 
SELECT ProductNumber, Name, ListPrice, ModifiedDate 
From   Production.Product 
WHERE  ModifiedDate < '2014-02-15'
