first of all thanks to seeing my post
i am new to Teradata
my Issue is :
we have lookups for to maintaining the unique keys
in staging we have duplicates values which is loaded into lookups too as a unique value
lets say in staging empid is having same number 15 times and lookup we have loaded only one value that is unique
in joining condition we are using same column this is getting 15 values i am getting by joining
i need only one value which is matched
how can i do this
