I'm really struggling with how to insert an else in my case statement with different conditions...I'm not sure if it's the syntax that is wrong or what?it's not working, I don't have any error messages, the problem is I still have a Null in my alias for some cases...
UPDATE Table
SET Alias = SUBSTRING(Names, 10, 40);
UPDATE Table
SET Alias = CASE WHEN Alias LIKE 'core.user%' OR Alias LIKE 'core.idea%' OR Alias LIKE'core.form%'
THEN STUFF(Alias, CHARINDEX('.', Alias) + 5, 0, '-')
WHEN Alias LIKE 'core.badge%' OR Alias LIKE 'core.award%' OR Alias LIKE 'core.field%' OR Alias LIKE 'core.audit%' OR Alias LIKE 'core.event%'
THEN STUFF(Alias, CHARINDEX('.', Alias) + 6, 0, '-')
ELSE CASE len(Alias) when charindex('.',Alias) +4 then Alias
ELSE CASE len(Alias)when charindex('.',Alias)+ 5 then Alias
END
END
END;
/*the result for this part is:*/
Names Alias
idealink.core.userbadge core.user-badge
idealink.core.ideacategories core.idea-categories
idealink.core.awardtype core.award-type /*till here it's working,but when*/
idealink.core.user NULL ---I'd like to have (core.user)----
idealink.core.idea NULL ---I'd like to have (core.idea)----
idealink.core.award NULL ---I'd like to have (core.award)----
/*I think the problem is here, I'm having Null*/
The purpose of all this is get rid of the idealink, and put a dash between the words when the string is too long after the core. ;but in some cases the string is not so long, so I don't need the dash like (core.user,core.idea,core.award) and so on, just get rid of the idealink.
I really appreciate any help of you guys. Thanks
The reason is because core.user and core.userbridge would both fall under the criteria you defined for Alias like 'core.user%'
To explicitly set values for core.user,core.idea,core.award, you would do as follows.
Check the portion between the /****************/
UPDATE Table
SET Alias = SUBSTRING(Names, 10, 40);
UPDATE Table
SET Alias = CASE /*****************************************************************************************/
WHEN Alias in('core.user','core.idea','core.award')
THEN Alias
/*****************************************************************************************/
WHEN Alias LIKE 'core.user%' OR Alias LIKE 'core.idea%' OR Alias LIKE'core.form%'
THEN STUFF(Alias, CHARINDEX('.', Alias) + 5, 0, '-')
WHEN Alias LIKE 'core.badge%' OR Alias LIKE 'core.award%' OR Alias LIKE 'core.field%' OR Alias LIKE 'core.audit%' OR Alias LIKE 'core.event%'
THEN STUFF(Alias, CHARINDEX('.', Alias) + 6, 0, '-')
ELSE CASE len(Alias) when charindex('.',Alias) +4 then Alias
ELSE CASE len(Alias) when charindex('.',Alias)+ 5 then Alias
END
END
