How to Select Only the Row(s) with Maximum Value in a Column Using Aggregate Functions.
Selecting the Row with Maximum Value, but the Column with this Info is an Aggregate Function When working with databases, especially those that use aggregate functions like SUM() or MAX(), it can be challenging to return only the row(s) that have the maximum value. This problem arises because the aggregate function calculates a value that represents the sum of all values in a column, rather than providing a single value for each row.

Improving SQL Queries: Using LEFT OUTER JOIN to Fetch Data from Multiple Tables Based on Conditions
Understanding the Problem and the SQL Query As a developer, we often encounter situations where we need to fetch data from multiple tables based on certain conditions. In this case, we have two tables: e_state and usr. The e_state table has three columns: State_id, country_id, and state_name. The usr table is used to store user inputs, including a state id that needs to be compared with the e_state table. When we fetch records from the usr table, we need to include data from the e_state table if there’s a match.
