I have a query:
select * from x, y
where x.a = y.a
and x.c = '1234ABC'
this query runs very quickly, instead if I use:
select * from x,y
and x.c = <Parameter1>
and put value 1234ABC in parameter, the query is slow. Can anyone please help why?
We're going to need something more solid to go off. Have you run a Tableau performance recording? Do you have a trace from the database which shows the exact query being run by Tableau?
