How can I execute multiple Cypher queries simultaneously in the Memgraph Lab editor?

I'm using Memgraph Lab for querying my graph database. Sometimes, I need to execute multiple Cypher queries in one go. How can I run multiple queries at once in the Memgraph Lab editor? When I run this:

MATCH (n:Person) WHERE n.name = 'Alice' RETURN n
MATCH (n:Person) WHERE n.age > 25 RETURN n

I get an error:

Query failed: MATCH can't be put after RETURN clause or after an update.
Solution

  • A delimiter for queries is ;, when you specify multiple queries in the editor and separate them by ;, Memgraph Lab will execute each of those queries serially and all in separated transactions. Just add the to the end of lines

    MATCH (n:Person) WHERE n.name = 'Alice' RETURN n;
MATCH (n:Person) WHERE n.age > 25 RETURN n;
