Sorting Values in a Column
Another post for me that is simple and hopefully serves as an example for people trying to get blogging as #SQLNewBlogger s.
This was a post that caught my eye, since I』d just written a piece on STRING_SPLIT() . Someone had this data:
DECLARE @Names VARCHAR(8000) = 'Steve, Grant, Kathi, Kendra';
They wanted this returned as a string that was sorted, so that the values would be:
Grant, Kathi, Kendra, Steve
String manipulation isn』t the strength of SQL Server, but we can do this with STRING_SPLIT(). If we use STRING_SPLIT(), we get a list of values. We want to remove the spaces after the comma, so we use REPLACE to remove that.
SELECT * FROM STRING_SPLIT(REPLACE(@Names, ' ', ''), ',') ORDER BY value;
We can then aggregate these back together in a variable assignment, adding the comma for each row.
SELECT @newtext = @newtext + Value + ', ' FROM STRING_SPLIT(REPLACE(@Names, ' ', ''), ',') ORDER BY value;
This gives us:
A quick T-SQL application of some skills I learned. Can you do something similar? Maybe order dates or numbers that are in a string in the wrong order?
That should be a 10-15 minute post.
