| If I have a single CASE expression, is it only possible to produce values in one column or can I have multiple values in multiple columns ?Take the following example:The following statement will put whatever values in the column aliased as DoINeedHelp...SELECT (CASE WHEN needhelp > 'No' THEN contactsqlteam ELSE NULL END) AS DoINeedHelpFROMi.needhelpfilesBut if I want another column with values from the same condition, do I need to duplicate the CASE statement or is there a means of doing this from within one statement?i.e - can I do something similar to this (obviously it doesn't work as I have it here):SELECT (CASE WHEN needhelp > 'No' THEN contactsqlteam AS DoINeedHelp, dontknow AS NotTooSure ELSE NULL END)FROMi.needhelpfilesor is it necessary to do this:SELECT (CASE WHEN needhelp > 'No' THEN contactsqlteam ELSE NULL END) AS DoINeedHelp, (CASE WHEN needhelp > 'No' THEN dontknow ELSE NULL END) AS NotTooSureFROMi.needhelpfilesYour help is appreciated...Regards |

| The column alias should come after the END. Its necessary to have two case statements. |
