OrientDB - Move Vertex
Move Vertex command in OrientDB is to move one or more vertices from current location to different class or cluster. If you are applying move command on a particular vertex, then it will update all the edges that are connected to this vertex. If you are specifying a cluster to move vertex, then it moves the vertices to the server owner of the target cluster.
The following statement is the basic syntax of Move Vertex Command.
MOVE VERTEX <source> TO <destination> [SET [<field>=<value>]* [,]] [MERGE <JSON>] [BATCH <batch-size>]
Following are the details about the options in the above syntax.
<source> − Defines the vertex you want to move. It accepts Record ID of a particular vertex or array of Record IDs for vertices.
<destination> − Defines where you want to move the vertex. It supports either class or a cluster as destination.
SET − Sets the values to fields.
MERGE − Sets the values to fields through JSON.
BATCH − Defines the batch size.
Note − This command updates all connected edges, but not links. When using Graph API, it is recommended to use edge connected to vertices.
Example
Try the following examples to learn how to move vertices.
Execute the following query to move a single vertex having Record ID #11:2 from its current position to Class Employee.
orientdb> MOVE VERTEX #11:2 TO CLASS:Employee
If the above query is executed successfully, you will get the following output −
Move vertex command executed with result '[{old:#11:2, new:#13:0}]' in 0.022000 sec(s)
Execute the following query to move set of vertices from the class ‘Customer’ to class ‘Employee’.
orientdb> MOVE VERTEX (SELECT FROM Customer) TO CLASS:Employee
If the above query is executed successfully, you will get the following output.
Move vertex command executed with result '[{old:#11:0, new:#13:1},{old:#11:1, new:#13:2},{old:#11:2, new:#13:3}]' in 0.011000 sec(s)
