set label in cypherquery dynamically

Question

Im trying to store some data in a neo4j db with the following (broken down query) wich works, not 100% proper but all data are send to my db:

var query2Neo = "CREATE (p:Person { samAccountName:'" + de.Properties["samAccountName"].Value + "'});

As my next step I try to write the label with real data not just person:

 var query2Neo = "CREATE (p:'" + de.Properties["samAccountName"].Value + "' { samAccountName:'" + de.Properties["samAccountName"].Value + "'})";

thats not working, but should I think?

thank you

Answer 1

This just due to the single quote around the label.

Your code will generate a query like that CREATE (n:'Person' { ...}) and it's not valid.

You should use the backtick instead ( ` ) so it

CREATE (n:`Person` { ...})

So your code should be :

var query2Neo = "CREATE (p:`" + de.Properties["samAccountName"].Value + "` { samAccountName:'" + de.Properties["samAccountName"].Value + "'})";

Moreover, for your properties values, you should use query parameters instead of generating the cypher query in your code (but this not possible for label). It's possible to send map as a parameter.
