Hi, I'm using H2 via Hibernates EntityManager and noticed that the JPQL function "ISNULL" does not work (function not found). I looked into H2Dialect, and obviously translation of ISNULL is not covered. Maybe it should use registerFunction to map from ISNULL to IFNULL. However, COLESCE works fine, no need to use a custom dialect for this. Maybe COALESCE should be used in favor to ISNULL. The TSQL (MS SQL Server) documentation categorizes ISNULL as system function (http:// msdn.microsoft.com/en-us/library/ms184325.aspx) and CALESCE (together with CASE and NULLIF) as expressions (http://msdn.microsoft.com/en-us/ library/ms190349.aspx). Strange that this does not work out-of-the-box with H2, and I did not find related information or bug reports. And why is ISNULL contained in the JPA 2 specification?
