To calculate the sum of multiple columns in Oracle, you can use the SQL SUM() function along with the + operator to add the values of each column.
For example, if you have two columns named "column1" and "column2" in a table named "table1", you can calculate the sum of these two columns with the following SQL statement:
SELECT SUM(column1 + column2) AS total_sum FROM table1;
This will calculate the sum of the values in column1 and column2 for each row in the table1 and display the total sum as "total_sum" in the result set. You can also include additional columns in the calculation by adding them with the + operator inside the SUM() function.

What is the easiest query to sum up values from multiple columns in Oracle?
The easiest query to sum up values from multiple columns in Oracle is to use the SELECT statement along with the SUM() function to add up the values of the columns. Here is an example query:
1 2 |
SELECT SUM(column1 + column2 + column3) AS total_sum FROM your_table_name; |
This query will sum up the values in column1, column2, and column3 from the specified table and return the total sum as total_sum. You can replace your_table_name with the actual name of your table and adjust the column names accordingly.
How to aggregate data from multiple columns in Oracle using SQL?
To aggregate data from multiple columns in Oracle using SQL, you can use the GROUP BY clause along with aggregate functions such as SUM, COUNT, AVG, MAX, and MIN. Here is a simple example to demonstrate how to aggregate data from multiple columns:
Suppose you have a table called "sales_data" with the following columns: "product_id", "quantity_sold", and "revenue".
You can use the following SQL query to aggregate the total quantity sold and total revenue for each product_id:
1 2 3 4 5 |
SELECT product_id, SUM(quantity_sold) AS total_quantity_sold, SUM(revenue) AS total_revenue FROM sales_data GROUP BY product_id; |
This query will group the data by product_id and calculate the total quantity_sold and total revenue for each product_id. You can also add other aggregate functions or columns to this query as needed.
How to use the SUM function to add values from multiple columns in Oracle?
To use the SUM function to add values from multiple columns in Oracle, you can specify the columns you want to add within the function. Here is the general syntax for using the SUM function in Oracle:
1 2 |
SELECT SUM(column1 + column2 + column3) AS total_sum FROM your_table_name; |
In this example, column1, column2, and column3 are the columns from which you want to add values, and your_table_name is the name of the table containing these columns. The SUM function will add the values from all three columns and display the total sum as total_sum.
You can customize this query based on your specific requirements, such as adding more columns or filtering the data before performing the sum calculation. Just make sure to adjust the column names and table name accordingly.
How to calculate the sum of two or more columns in Oracle using SQL?
To calculate the sum of two or more columns in Oracle using SQL, you can use the following query:
1 2 |
SELECT column1 + column2 + column3 AS total_sum FROM your_table_name; |
In this query:
- column1, column2, and column3 are the columns you want to calculate the sum for.
- your_table_name is the name of the table where these columns are located.
You can customize this query based on your specific requirements, such as including additional columns or applying a filter to only sum certain rows.
