Execute a Cypher query

Sends a Cypher query string to LadybugDB and returns an lb_result object. For DDL or DML statements (CREATE TABLE, CREATE, MERGE, …) the result contains metadata; for MATCH/RETURN it contains rows.

Usage

lb_execute(conn, query, parameters = NULL)

Arguments

conn

An lb_connection object from lb_connection().

query

A single character string containing a Cypher query.

parameters

A named list of query parameters for parameterised queries. NULL (default) means no parameters.

Value

An object of class lb_result.

Examples

if (FALSE) { # \dontrun{
db   <- lb_database(":memory:")
conn <- lb_connection(db)
lb_execute(conn, "CREATE NODE TABLE Person (name STRING, PRIMARY KEY(name))")
lb_execute(conn, "CREATE (:Person {name: $name})",
           parameters = list(name = "Alice"))
} # }
