SQL how to sum multiple columns Code Answer's
SQL (Structured Query Language) is a language for manipulating, retrieving, and reporting data in databases. It is a standard language for interacting with relational database management systems (RDBMS).
The SQL command to sum multiple columns is:
SELECT column1,column2 FROM table_name GROUP BY column1,column2 HAVING sum(column1) + sum(column2) <> 0
sql add two values together
SELECT ID, SUM(VALUE1 + VALUE2)
GROUP BY ID
--or simple addition
(VALUE1 + VALUE2) as AddedValues
To explain this statement in more detail:
SELECT - This tells the SQL engine which columns to return. If you don't specify the data types for each column, they will be returned as strings by default. You can also use DISTINCT if you want to show only unique values in a column.
FROM - The FROM clause specifies the table from which you are selecting data.
