Hello, A schema is a graph name and a label is a table name. Id and properties field are columns in vertices and id, start_id, end_id, and properties are columns in the edges. Use the agtype_access_operator(properties, key) to get to get a property value. Know all that you can use Postges' standard DDL language to implement constraints and unique values. ``` ALTER TABLE graph_name.label_name ADD CONSTRAINT constraint_name CHECK(agtype_access_operator(properties, "name_of_property") != '"Check against here"'::agtype); ``` -- This is an automated message from the Apache Git Service.
