INSERT
statement
The INSERT
statement can be used to insert or update data into the database, using the same statement syntax as the traditional SQL Insert statement.
Note: This statement can not be used to create graph relationships. For that, use the RELATE
statement.
Statement syntax
SurrealQL SyntaxINSERT [ IGNORE ] INTO @what
[ @value
| (@fields) VALUES (@values)
[ ON DUPLICATE KEY UPDATE @field = @value ... ]
]
;
Example usage
The following query shows example usage of this statement.
INSERT INTO company {
name: 'SurrealDB',
founded: "2021-09-10",
founders: [person:tobie, person:jaime],
tags: ['big data', 'database']
};
As with the traditional SQL insert statement syntax, records can be inserted by specifying the fields and values by using the VALUES
keyword.
-- Insert a single record
INSERT INTO company (name, founded) VALUES ('SurrealDB', '2021-09-10');
-- Insert multiple records
INSERT INTO company (name, founded) VALUES ('Acme Inc.', '1967-05-03'), ('Apple Inc.', '1976-04-01');
When using the VALUES
clause, it is possible to update records which already exist by specifying an ON DUPLICATE KEY UPDATE
clause. This clause also allows incrementing and decrementing numeric values, and adding or removing values from arrays. To increment a numeric value, or to add an item to an array, use the +=
operator. To decrement a numeric value, or to remove an value from an array, use the -=
operator.
INSERT INTO product (name, url) VALUES ('Salesforce', 'salesforce.com') ON DUPLICATE KEY UPDATE tags += 'crm';
Field names inside ON DUPLICATE KEY UPDATE
refer to the fields of the existing record. To access the fields of the new record that was attempted to be inserted, prefix the field name with $input
:
INSERT INTO city (id, population, at_year) VALUES ("Calgary", 1665000, 2024)
ON DUPLICATE KEY UPDATE
population = $input.population,
at_year = $input.at_year;
Using the insert statement, it is possible to copy records easily between tables. The records being copied will have the same id in the new table, but the record id will signify the new table name.
INSERT INTO recordings_san_francisco (SELECT * FROM temperature WHERE city = 'San Francisco');
Furthermore, it is possible to perform a bulk insert in a single query. The @what
part of the syntax can be either a single object or an array of objects.
INSERT INTO person [
{id: "person:jaime", name: "Jaime", surname: "Morgan Hitchcock"},
{id: "person:tobie", name: "Tobie", surname: "Morgan Hitchcock"},
]
It is also possible to import/bulk insert data using http functions
. The following example shows to import posts from jsonplaceholder by making get request, the data returned is array of objects.
-- Import format
-- [
-- {
-- "userId": 1,
-- "id": 1,
-- "title": "..",
-- "body": ".."
-- },
-- ...
-- ]
INSERT INTO posts http::get("https://jsonplaceholder.typicode.com/posts");
If the data returned is a nested object, you can provide a key to import the records.
-- Import format
-- {
-- "products": [
-- {
-- ...
-- }
-- ],
-- "total": 100,
-- "skip": 0,
-- "limit": 30
-- }
INSERT INTO products http::get("https://dummyjson.com/products")["products"];
