SQL: Failing Group By queries due to different ExpressionIds (#43072)
Fix an issue that arises from the use of ExpressionIds as keys in a lookup map that helps the QueryTranslator to identify the grouping columns. The issue is that the same expression in different parts of the query (SELECT clause and GROUP BY clause) ends up with different ExpressionIds so the lookup fails. So, instead of ExpressionIds use the hashCode() of NamedExpression. Fixes: #41159 Fixes: #40001 Fixes: #40240 Fixes: #33361 Fixes: #46316 Fixes: #36074 Fixes: #34543 Fixes: #37044 Fixes: #42041
