# Add Neo4j support and Cypher generating Chain The idea is to add support for querying Graph Databases that use Cypher query language like Neo4j. Since queries need to be constructed at query time, we use a similar approach as the text2sql, but instead of generating SQL statements, we generate Cypher statements based on the provided graph schema, which makes this a generic solution. # Todo - [x] Integration test - [x] Better exception handling Fixes # (issue) #4625 --------- Co-authored-by: Harrison Chase <hw.chase.17@gmail.com>
