Description
The lead and lag window functions support an extra clause IGNORE / RESPECT NULLS at the end. IGNORE NULLS means to exclude window entries that evaluate to null while the default behavior RESPECT NULLS would include them.
Syntax is i believe for example NTH_VALUE(col1) IGNORE NULLS OVER (..)
