window functions in view return incorrect results ------------------------------------------------- Key: TEIID-2501 URL: https://issues.jboss.org/browse/TEIID-2501 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 7.5 Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Blocker Fix For: 8.4 conditions and limits above a view are too broadly allowed to be pushed through a view layer containing window functions. From the forum posting for example: {code} SELECT "StateProvinceID" , COUNT(*) OVER (PARTITION BY a."CountryRegionCode") AS num FROM salestaxrate a WHERE "TaxType" = 3{code} returns the correct counts, where as {code} SELECT * FROM ( SELECT "StateProvinceID" , COUNT(*) OVER (PARTITION BY a."CountryRegionCode") AS num FROM salestaxrate a WHERE "TaxType" = 3 ) x WHERE "StateProvinceID" = 45 {code} returns counts where the state province id condition is applied before the windowing. The currently logic will only prevent the criteria from being pushed if it is directly applied against a computed window value.
