Average and Case in SQL

阅读更多关于 Average and Case in SQL

I am trying to generate a report and the following code does not produce the desired results which gives me 2 lines rather than one. The ScoreTypeID could have values of 22, 52, 3 or 4 . if it is 22 or 52, I need the average and if not I need to show 0. Any idea what may be the problem ? Thanks. CASE WHEN FAS1.ScoreTypeID = 22 THEN avg(fas1.totalscore) WHEN FAS1.ScoreTypeID = 52 THEN avg(fas1.totalscore) ELSE 0 END AS 'Total Score', I think in your full query, you are missing the GROUP BY clause, eg SELECT ... FROM .... WHERE .. GROUP BY FAS1.ScoreTypeID I think this is what you want: coalesce

Any ideas how to determine what age group an individual belongs in Excel?

阅读更多关于 Any ideas how to determine what age group an individual belongs in Excel?

I have 2 columns in an Excel spread sheet. First column header is called AGE and the second column header is called Age_Group. The ages in the AGE column are between 18 and 45. There could be multiple rows with same age. I am tasked with determining what age group a certain age falls into and then print out that age group. For instance, if someone’s age is 18, I would like to use IF statement or CASE statement to determine that age 18 is between 18 and 24 and then put that value into Age_Group column as 18-24. If age is 19, again, it will fall into the group of 18-24 in Age_Group column. If
