How does knex.max work?
knex.max is a function that returns a new instance of the QueryBuilder class that constructs a SELECT query with a MAX function to get the maximum value of a specified column in a table. The MAX function is used in the SQL query to return the highest value of a specific column, as specified by the user. The knex.max function takes one argument, which is the name of the column for which the maximum value is to be retrieved.
Ai Example
1 2const maxAge = await knex("users").max("age"); console.log(maxAge); // Outputs { 'max(`age`)': 50 }
