SQLite MAX Function
As mentioned earlier, the SQLite MAX function can be used in various ways based on the requirements of the user. If MAX is used all alone then it can used to fetch the maximum value from the set or the column passed as its parameter. When the MAX function is used with other Aggregate Functions like HAVING or GROUP BY it can be manipulated by the user as their requirement. The generic syntax of the MAX function is given below –
Syntax:
MAX (COLUMN_NAME | EXPRESSION) FROM TABLE_NAME [WHERE CONDITION] [GROUP BY EXPRESSION]
Explanation
- First, we need to pass the Column_Name or an Expression in the first parenthesis. Expression is passed when MAX is used with other Aggregate Functions like GROUP BY, if MAX is used alone, then COLUMN_NAME will be passed.
- Secondly, we need to tell the MAX function to work on a certain table by passing its name using FROM. Now if MAX is used alone, then that would be the end of the statement. But if it is used with others then we can also pass some condition using WHERE or some Expression while using GROUP BY. The WHERE condition and the GROUP BY Expression are Optional.
SQLite MAX() Function
MAX function is a type of Aggregate Function available in SQLite, which is primarily used to find out the maximum value from a given set (a column that is passed as its parameter). Other than that, the MAX function can also be used with other Aggregate functions like HAVING, GROUP BY, etc to sort or get some values that are obeying the condition mentioned by these other Aggregate Functions.
In this article, we will see how we can use the MAX function to do various tasks and how the MAX function can be used in various ways to get more precise outputs from the table.
