Yes you can update property of multiple nodes without specifying every node
individually.
If you want to update nodes based on some condition. You can do this in 2
ways :
Updating nodes based on a condition:
1. You can use match clause with come condition that selects the node that
you want to update
2. Then use set clause to update the desired properties.
SQL:
`MATCH (n:labelt)
WHERE n.Property = 'random value'
SET n.nProperty = 'new value'`
In above case all nodes with labelt and with property 'Property' that equals
to a new balue random value will be selected and their new property will be
updated to new value.
Another method can be to update nodes of a specific label:
1. In above scenario by just eliminating the condition in match clause you
can update all the nodes.
SQL:
`MATCH (n:labelt)
SET n.newProperty = 'new value'`
In above case all nodes with labelt will have new property updated to a new
value
Using above 2 ways you can update properties of multiple nodes in graph
database using a single query without specifying each node individually.
