Hello List! OK, so I'm new to SQL and Postgres and am working on taking over this DB work, and ran across a command that I'm not sure of and am wondering if you can help me with... Probably a basic SQL question, but thought more than one person on here would be able to point me in the right direction!! In on of the tables in the DB, there is a constraint defined that I'm not familiar with: CONSTRAINT "Relationship182" FOREIGN KEY (elementid) REFERENCES element (elementid) MATCH SIMPLE ON UPDATE CASCADE ON DELETE CASCADE Not quite sure what the: CONSTRAINT "Relationship182" is exactly... can anyone help me with this one? Haven't seen this one yet... Thanks much for your help and support! -Jeanna
