XQuery Add

In XQuery, you can perform addition operations on numeric values using the + operator. The + operator is used to add two or more numbers together and return the result as a numeric value.

Here are some examples of how to use the + operator in XQuery:

1. Adding Two Numbers:

let $num1 := 10
let $num2 := 20
let $sum := $num1 + $num2
return $sum

Output: 30

In this example, we assigned the values 10 and 20 to the variables $num1 and $num2, respectively. Then, we added these two variables together using the + operator and stored the result in the variable $sum.

2. Adding Multiple Numbers:

let $numbers := (5, 8, 12, 3, 7)
let $total := sum($numbers)
return $total

Output: 35

In this example, we have a sequence of numbers stored in the variable $numbers. We use the sum() function to calculate the sum of all the numbers in the sequence and store the result in the variable $total.

3. Adding Decimal Numbers:

let $num1 := 3.14
let $num2 := 2.86
let $result := $num1 + $num2
return $result

Output: 6.0

In this example, we added two decimal numbers, 3.14 and 2.86, using the + operator. The result is a decimal value, which is 6.0.

The + operator can be used with various numeric data types, including integers and decimals. It is a straightforward and commonly used operator for performing addition operations in XQuery.
