ReQL command: add

Command syntax

value.add(value[, value, ...]) → value

time.add(number[, number, ...]) → time


Sum two or more numbers, or concatenate two or more strings or arrays.

The add command can be called in either prefix or infix form; both forms are equivalent. Note that ReQL will not perform type coercion. You cannot, for example, add a string and a number together.

Example: It’s as easy as 2 + 2 = 4.


// Result:

Example: Concatenate strings.

r.expr("foo").add("bar", "baz").run(conn);

// Result:

Example: Concatenate arrays.

r.expr(["foo", "bar"]).add(["buzz"]).run(conn);

// Result:
[ "foo", "bar", "buzz" ]

Example: Create a date one year from now.*24*60*60).run(conn);

Example: Use args with add to sum multiple values.

int[] vals = { 10, 20, 30 };

// Result:

Example: Concatenate an array of strings with args.

String[] vals = { "foo", "bar", "buzz" };

// Result:
