Select Rows with Maximum Value on a Column in SQL Server Example 1. If you are returning the group column, and the column with Maximum value, you can use the below statement. As you can see, we used Max function along with Group By. USE SQL Tutorial GO SELECT Occupation,MAX(Sales) AS MaxSale FROM Employee GROUP BY Occupation. MAX ignores any null values. MAX returns NULL when there is no row to select. For character columns, MAX finds the highest value in the collating sequence. MAX is a deterministic function when used without the OVER and ORDER BY clauses.

Arguments
ALL
Applies the aggregate function to all values. ALL is the default.
DISTINCT
Specifies that each unique value is considered. DISTINCT is not meaningful with MAX and is available for ISO compatibility only.
expression
Is a constant, column name, or function, and any combination of arithmetic, bitwise, and string operators. MAX can be used with numeric, character, uniqueidentifier, and datetime columns, but not with bit columns. Aggregate functions and subqueries are not permitted.
For more information, see Expressions (Transact-SQL).
OVER (partition_by_clause [ order_by_clause ] )
partition_by_clause divides the result set produced by the FROM clause into partitions to which the function is applied. If not specified, the function treats all rows of the query result set as a single group. order_by_clause determines the logical order in which the operation is performed. partition_by_clause is required. For more information, see OVER Clause (Transact-SQL).
Return Types
Returns a value same as expression.
Remarks
MAX ignores any null values.
MAX returns NULL when there is no row to select.
For character columns, MAX finds the highest value in the collating sequence.
MAX is a deterministic function when used without the OVER and ORDER BY clauses. Toon shooters 2: the freelancers crack. It is nondeterministic when specified with the OVER and ORDER BY clauses. For more information, see Deterministic and Nondeterministic Functions.
Examples
A. Simple example
The following example returns the highest (maximum) tax rate in the AdventureWorks2012 database.
Here is the result set.
B. Using the OVER clause
The following example uses the MIN, MAX, AVG, and COUNT functions with the OVER clause to provide aggregated values for each department in the HumanResources.Department table in the AdventureWorks2012 database.
