Foreign Key Constraints Pdf Computer Programming Databases After some "reverse engineering" on the queries made by the navicat tool when opening the design table window for a table (queries retrieving info about foreign keys show up in the history window), here is a solution: cons.constraint name, cons.table name, cols.column name, cons.r constraint name, cons r.table name r table name,. Select a.table name, a.column name, a.constraint name, c.owner, referenced pk c.r owner, c pk.table name r table name, c pk.constraint name r pk from all cons columns a join all constraints c on a.owner = c.owner and a.constraint name = c.constraint name join all constraints c pk on c.r owner = c pk.owner and c.r constraint name = c pk.
