I want to creat a SQL statement that lets me SELECT recID FROM table WHERE refID!= [any existing values for recID in the current table] I'm having a hard time figuring out how to compare a column in a where clause to an array from another column. Basically I want to locate orphaned records that used to reference other records that have since been deleted. I tried investigating JOIN statements, both those seem to only apply to data in another table, not the current one. Any ideas for me? Thanks in advance.

Something like: SELECT recID FROM table WHERE refID not in (SELECT refID from...) arran.
