I'm reading an article in FoxTalk and have come across this phrase.

Does anyone know what is meant by a reflexive join??

Thanks,

Stewart

Hi Stewart

A reflexive join exists when a table is joined to itself through a second column. For example, the table Employee(EmployeeID,...,ManagerID)could have a join from ManagerID to EmployeeID.
