IGNORE NULLS- Ignore null values in the dataset when computing the last value over a partition. RESPECT NULLS- Respect null values in the dataset when computing last value over a partition.RESPECT NULLSis the default behavior if a NULLS option isn't specified. ...
LAST_VALUEis an analytic function. It returns the last value in an ordered set of values. If the last value in the set is null, then the function returnsNULLunless you specifyIGNORENULLS. This setting is useful for data densification. If you specifyIGNORE NULLS, thenLAST_VALUEreturns the fi...
