# Database

We will use the database, whose schema and data import commands are given here:

You can import this database by copy pasting the comands on that page.

# SET

SET is similar to SQL’s SET clause, and allows updating properties of node or relationship records to new values (possibly NULL).

## Examples:

### 1. Setting node properties

For example the following query sets the age property of the User node with name Adam to 50 (which is 30 in the original database).

Query:

MATCH (u:User)
SET u.age = 50


Similarly the following sets Adam’s age property to NULL. Query:

MATCH (u:User)

For example the following query sets the since property of the Follows relationship(From Adam to Karissa) to 2012 (which is 2020 in the original database).
MATCH (u0:User)-[f:Follows]->(u1:User)
