The SUM function is one of the aggregate functions in Oracle database, used to calculate the total sum of a specified column.<\/p>\n

Syntax: Sum of column<\/p>\n

Specifications:<\/p>\n

    \n
  1. Column: the name or expression of the column to calculate the total sum.<\/li>\n<\/ol>\n

    Return value: the calculated total sum.<\/p>\n

    Important points to note:<\/p>\n

      \n
    1. The SUM function can only be used with columns that are numerical in type.<\/li>\n
    2. The SUM function will ignore any NULL values in the column when calculating.<\/li>\n
    3. To calculate the total sum of multiple columns, you can use multiple SUM functions to calculate the sum of each column separately.<\/li>\n<\/ol>\n

      Assume there is a table called “orders” with columns “order_id” and “amount”, we can use the SUM function to calculate the total sum of the “amount” column.<\/p>\n

      SELECT SUM(amount) \r\nFROM orders;\r\n<\/code><\/pre>\n
      This will return the sum of all values in the “amount” column.<\/p>\n","protected":false},"excerpt":{"rendered":"
