Home -> Community -> Usenet -> c.d.o.server -> number <-> number(x,y) foreign keys: performance impact ?
I rand a script to check the health status of my database and it reports a
problem with some foreign keys where the referenced columns and the
referencing columns are of a different data type.
My question is:
Does oracle have to do conversion between a number column and a number(x,y) column ?
If so, that means that my joins are not optimal.
