Independent Column Calculation
New to SQL Server (T-SQL) and I am not able to find an answer to this question by searching online.
I am trying to write a query that will give me a max date and a count of events since that date in another column. The query I have so far is:
SELECT
[EmployeeKey], MAX([EvaluationDateTime]) AS [LastFailDate]
FROM
[DataWarehouse].[quality].[FactEvaluation_Current]
WHERE
EvaluationScoreTotal < 80.00
GROUP BY
[EmployeeKey];
I now need to add an additional column that will count all the events from the date returned as LastFailDate but I'm not sure where to add this into this query so that it won't be affected by the WHERE clause?
I think I need something like
SELECT
COUNT[EvaluationDateTime]
FROM
[DataWarehouse].[quality].[FactEvaluation_Current]
WHERE
[EvaluationDateTime] > [LastFailDate]
Any help or direction of where I can find the answer to this would be greatly appreciated.
Thanks

I think below query gives what you want.
SELECT * FROM
(
SELECT [EmployeeKey], MAX([EvaluationDateTime]) as [LastFailDate],COUNT[EvaluationDateTime] as [Count_LastFailDate]
FROM [DataWarehouse].[quality].[FactEvaluation_Current]
WHERE EvaluationScoreTotal < 80.00
GROUP BY [EmployeeKey]
)CNT
WHERE [EvaluationDateTime] > [LastFailDate];
But if you want more appropriate answer. Give DDL with sample data.

I get an "Invalid column name 'LastFailDate'." error. I think this is because LastFailDate is not a column which exist in my data It is created in the first column of the query? Thanks for your help.
