Mastering the SET Clause in Apache AGE A Comprehensive GuideApache AGE is a powerful graph extension for PostgreSQL that allows you to work with property graphs using standard SQL syntax One of the essential features in AGE is the SET clause which enables you to modify and update properties of vertices and edges within the graph In this blog post we will delve into the details of the SET clause in Apache AGE and explore its various capabilities and use cases The SET ClauseThe SET clause in Apache AGE is used to modify the properties of vertices and edges within a property graph It provides a flexible and intuitive way to update the graph data without having to rewrite the entire graph structure A set clause that does not have any subsequent clause is referred to as a terminal clause If a Cypher query concludes with a terminal clause the cypher function call will not yield any results Nevertheless it is still necessary to provide a column list definition for the cypher function call In the case of a terminal node in Cypher the column list definition should consist of a single value resulting in no data being returned in that particular variable How to use the SET ClauseGiven a graph with properties demo SELECT FROM cypher persons CREATE Person name Peter demo Person name Paul as persons agtype persons rows demo SELECT FROM cypher persons MATCH u RETURN u as persons agtype persons id label Person properties name Peter vertex id label Person properties name Paul vertex rows We can set a property on a node or relationship using SET QUERYdemo SELECT FROM cypher persons demo MATCH peter Person name Peter demo SET peter age RETURN peter demo as peter agtype peter id label Person properties age name Peter vertex row You can see that the newly updated vertex is returned by the query Removing a Property using SETTypically the REMOVE clause see REMOVE is used to eliminate a property However there are situations where utilizing the SET clause can be advantageous for property removal One such scenario arises when the property is derived from a parameter In such cases using the SET clause proves useful as an alternative method to remove the property QUERYdemo SELECT FROM cypher persons MATCH peter Person name Peter SET peter name NULL RETURN peter as peter agtype peter id label Person properties age vertex row I removed the the name property Peter using the SET clause by setting peter name to NULL And now the node is returned by the query and the name property is now missing Using one SET Clause for Multiple PropertiesIn other to achieve setting multiple properties using one SET clause you have to simply separate the properties using a comma QUERYdemo SELECT FROM cypher persons MATCH peter Person age SET peter name Peter peter surname Francis RETURN peter as peter agtype peter id label Person properties age name Peter surname Francis vertex row ConclusionThe SET clause in Apache AGE is a powerful tool for modifying property graphs efficiently Its flexibility and compatibility with standard SQL make it a valuable asset when working with graph data Understanding its syntax and capabilities opens up a range of possibilities for updating and managing graph properties in a seamless and intuitive manner ReferencesThe SET Clause Apache Age DocsThe REMOVE Clause Blog postVisit Apache AGE Website Visit Apache AGE GitHub Visit Apache AGE Viewer GitHub |
