JDBC needs a parameterized query evaluator

[nmondal]

See the following cypher queries:

[1]

MATCH (a:Entity), (b:Entity) WHERE a.urn = '%s' AND b.urn = '%s'
CREATE (a)-[r:%s { startTime: datetime(), endTime: null } ]->(b)  
RETURN a,b 

[2]

MATCH (a {urn:'%s'})-[r:%s]-(b {urn:'%s'})
SET r.endTime = datetime()

It takes 3 params. Entity1, Entity2, and a relation name.
But now the ordering gets changed, that is shame.

This solves it.
