I want the query to read the CSV file and create a node for each row in the file.
Here's the query:
CALL apoc.load.csv('FILE:///C:/Temp/Test/Test/Neo4jTest/import/Neo4j_AttributeProvenance.csv',{sep:","}) YIELD map
CALL apoc.create.node(map.NodeType, {key:map.NodeID}) yield node return count(*)
Here's the error:
Can't coerce `RootNode` to List<String>
Here's the data file:
NodeType,NodeID,SchemaName,TableName,AttributeName,DataType,PreviousNodeID
RootNode,queryprocessingtest.q01.testfieldatablec ,queryprocessingtest,q01,testfieldatablec ,varchar,
Node,queryprocessingtest.qc.testfieldatablec ,queryprocessingtest,qc,testfieldatablec ,varchar,queryprocessingtest.q01.testfieldatablec
Node,queryprocessingtest.ttablec.testfieldatablec ,queryprocessingtest,ttablec,testfieldatablec ,varchar,queryprocessingtest.q01.testfieldatablec
The first argument of the
apoc.create.node
procedure must be an array.So you need to convert the value of
map.NodeType
into an array:
