Max records12/28/2023 ![]() See also some VO 2max results for athletes for specific examples for a range of sports. The average young untrained female will score about 2.0 liters/minute or 38 ml.kg -1.min -1 compared to world class female endurance athletes which a few may exceed 70 ml.kg -1.min -1. ![]() In comparison, world class male endurance athletes in sports such as cycling and cross-country skiing typically achieved scores in excess of 80 ml.kg -1.min -1, and occasionally a few may exceed 90 ml.kg -1.min -1. We can use the MAX() function in SQL to fetch the greatest value of the columns of the tables or greatest of expressions that involve column values and even calculate the greatest value of columns in the grouped manner using the GROUP BY statement.Wikipedia lists VO 2max levels for the average young untrained male of about 3.5 liters per minute or 45 ml.kg -1.min -1. ![]() The execution of the above query statement will give the following output along with team ids and their respective greatest salaries. For this, we will have to use the group by statement and group the records based on team id and calculate the greatest salary by using MAX() function. The output should consist of the team id and the greatest salary of that team. Now, the situation is such that we have to calculate the greatest salary of the workers per team. Suppose that we have one table named workers consisting of the following records in it that are retrieved by executing a simple select query on that table. Even in some scenarios, the data from a single table need to be manipulated to get summarized data. When we have complex tables and relations between multiple tables, we have to query those tables using joins to retrieve data, usually for reporting purposes that consist of summarized data. We can even use the existing functions such as SUM() and COUNT() inside the MAX() function. Let us consider one example we will calculate the greatest of all the columns after they are multiplied by 10 and added by 1. We can use the MAX() function expressions to consider the value evaluated by fetching each of the formula or expression values containing column value to calculate the greatest value. The output of both of the above queries is as shown below. The output will be the same as that of the first query without a distinct function but internally the calculation of greatest value by MAX() function will only consider the column values that are repeated such as 100 and 150 only once. If we use SELECT MAX(num) FROM numbers statement to calculate the greatest value of num column, then each of the values will be considered while fetching the greatest value. Let us create one simple table named numbers and store the num column value in it. We will calculate the greatest value of SQL numbers using the MAX() function. Let us firstly consider a simple example that we used above. Given below are the examples of SQL MAX(): Example #1 – Using a single column. Then the max function will internally compare each of their values and finally derive 200 as the greatest maximum value. For example, consider that we have to find out a greatest of 50, 100, 150, and 200. The MAX() function collects all the values of the expression mentioned in it and adds them up, which is further divided by the number of values or expressions that were added to find out the final greatest value. When where clause is used, only filtered out data is considered for the greatest calculation by MAX() function. One optional thing is the use of a where clause to mention the conditions and restrictions that the records of the table should fulfil to consider that record’s column value for fetching the greatest value. The use of the FROM table name clause is required. Where expression can be any name of the column of the table or a formula built up using column names and static literal values or variables, the table_name is the name of the table from which you want to retrieve the records and calculate the greatest value from one of their columns.
