Hello,

I'm looking at http://mikehillyer.com/articles/managing-hierarchical-data-in-mysql/
and since I'm using SQL Server so need to know what is the equivalent of
SELECT @myRight := rgt FROM nested_category
--WHERE name = 'TELEVISIONS';

Open in new window


in SQL Server.

Thanks,
ak

It should be:

Declare @myRight varchar  -- or Int, or Numeric, or whatever it ought to be

SELECT @myRight = rgt FROM nested_category
--WHERE name = 'TELEVISIONS'

Open in new window


I'm assuming the where clause is remarked as you don't need it, but of course removing the -- will make it operable again.

I hope that helps

right ... thank you!

do we have any things like format specifier as we have in C?
sprintf("some string %i , %s", intVar1, StringVar2);

Any idea?

Thanks.

You just have the SQL print command but you can concatenate strings with a +

eg

Print 'This is the result: ' + @myRight

SQL 2012 introduces a FORMAT command, but in prior versions formatting is considered something left to the UI layer.

Hi Akohan

I kind of thought my solution was the one that helped with your original question, but no points? :-(
