问题 Hi I was looking a way to filter an calculated column. I just fund using HAVING. I was wondering if with the need to repeat the calculation on having and select, my SQL have to calculate two times and consequently have performance impact. ie: USE AdventureWorks2012 ; GO SELECT SalesOrderID, SUM(LineTotal) AS SubTotal FROM Sales.SalesOrderDetail GROUP BY SalesOrderID HAVING SUM(LineTotal) > 100000.00 ORDER BY SalesOrderID ; 回答1: The expense in doing the calculation is in arranging the group by

问题 SELECT CASE WHEN SUM(X.Count)*3600 is null THEN '0' ELSE SUM(X.Count)*3600 END AS PJZ, X.Mass FROM X WHERE X.Mass > 2000 HAVING ((X.Mass / PJZ * 100) - 100) >= 10; Getting: ERROR: Column »pjz« doesn't exists. How can I do something like this? 回答1: Wrap it into a derived table: SELECT CASE WHEN PJZ = 0 THEN 100 ELSE PJZ END as PJZ, mass FROM ( SELECT CASE WHEN SUM(X.Count)*3600 is null THEN '0' ELSE SUM(X.Count)*3600 END AS PJZ, X.Mass FROM X WHERE X.Mass > 2000 GROUP BY X.mass ) t WHERE PJZ =

问题 I made a bit of a fool out of myself earlier today on this question. The question was using SQL Server, and the correct answer involved adding a HAVING clause. The initial mistake I made was to think that an alias in the SELECT statement could be used in the HAVING clause, which is not allowed in SQL Server. I made this error because I assumed that SQL Server had the same rules as MySQL, which does allow an alias to be used in the HAVING clause. This got me curious, and I poked around on

问题 I need to use an alias in the WHERE clause, but It keeps telling me that its an unknown column. Is there any way to get around this issue? I need to select records that have a rating higher than x. Rating is calculated as the following alias: sum(reviews.rev_rating)/count(reviews.rev_id) as avg_rating 回答1: You could use a HAVING clause, which can see the aliases, e.g. HAVING avg_rating>5 but in a where clause you'll need to repeat your expression, e.g. WHERE (sum(reviews.rev_rating)/count
