Re use ain't called cheating! Its all about not reinventing the wheel , and saving time, TIME is something you can't buy, store.. Just keep spending it Copy Paste it part of the job... not called cheating :D
Brilliant, just simply brilliant. Now Do you have a set of videos for data analytics such as R, SAS etc. If no, could you provide some useful links or websites?
Hi Andrew, I keep getting the following error when I called my scalar function in a different query. Msg 4121, Level 16, State 1, Line 1 Cannot find either column "dbo" or the user-defined function or aggregate "dbo.DateG2J", or the name is ambiguous Here is the statement where I called the function. select [dbo].[DateG2J](sddrqj,101) from testdta.f4211; I refresh the local cache, no luck. What do you think is going on? Thanks Abner
Is there a way to automatically convert code like 'GO', 'USE' and 'CREATE' in uppercase? Either from the options within sql-server or with some simple code? Thanks!
Please correct me if I'm wrong but the variable answer seems to be redundant here. Could you have achieved this with the following? IF @SpacePosition = 0 RETUN @FullName ELSE RETURN @LEFT(FullName, @SpacePosition - 1) Thanks.
Hi! While you can do this in some other languages, you can't do it in t-sql. The final statement in a scalar-valued function must be a RETURN statement - nesting a RETURN statement in a control flow statement such as IF breaks that rule. you could do it this way: return iif( charindex(' ', @FullName) = 0 ,@FullName ,left( @FullName ,charindex(' ', @FullName) ) )
Hi Jonathan, you can certainly create functions in MySQL although there are a few syntax differences compared to SQL Server. Here's the documentation for the MySQL Create Function statement dev.mysql.com/doc/refman/8.0/en/create-procedure.html I haven't spent much time with MySQL so I'm afraid that I can't offer much more advice!
@@jonathanjordan21 Hi Jonathan, I believe the name of the application is MySQL Workbench, not Benchmark. But I would just search for "mysql create function", there are hundreds of videos on the topic. I hope that helps!
@@WiseOwlTutorials i think its because MySQL server doesnt support function to return table. thats why my code doesnt work maybe i should use microsoft DBMS instead
@@jonathanjordan21 Hi Jonathan, I assumed that you were creating a scalar function as that is the subject of this video. Yes you're correct that MySQL doesn't support table-valued functions. Using Microsoft SQL Server would be one option to allow you to do this.

Thanks very much! Happy to hear that people are still finding them useful, thanks for watching and taking the time to comment!
this is the most complete tutorial i've seen in my life
Thanks Valentin!
I seriously owe you so much. I have improved my skills in VBA and SQL thanks to you and helped me at my career. YOU ROCK!!!!!!!!!!!!!!!!

Thanks for the update, do when can we expect R tutorials online like SQL. I learnt VBA, SQL from u and solely depend on your videos.
Also any plans on python ? And if so when?
3:02 you need to use small letters for days and year to work accurately, "dd MM yy" month has to be capital
Excellent video!
Very helpful videos. Thanks a lot!
Thanks a LOT.
Sir, could you please make a Video on CTEs. Why use CTEs ???

Hi Andrew,
I keep getting the following error when I called my scalar function in a different query.
Msg 4121, Level 16, State 1, Line 1
Cannot find either column "dbo" or the user-defined function or aggregate "dbo.DateG2J", or the name is ambiguous
Here is the statement where I called the function.
select [dbo].[DateG2J](sddrqj,101) from testdta.f4211;
I refresh the local cache, no luck.
What do you think is going on?
Thanks
Abner

Hi! How can I find system functions. Actually I want to copy a function from 2016 to 2012. Function name is String_spilt()
I mean the code
Thanks but I am using 2012 and i want result in rows that is not having fix length
what's with the sound?
I couldn't quite understand the difference between" Functions " and " Procedures "
May someone explain It to me, please.
functions, flash card style..
Coming from someone just learning SQL, I find the "extras" on the screen to a bit distracting. Just show what we need to see, not everything else.
+Collin Wright Other than that, very good video.
Excellent videos! Thanks so much!
You're very welcome, thanks for watching!
