Stairway to Advanced T-SQL Level 6: Creating Rows Of Data Using The UNPIVOT Operator

Gregory Larsen from SQLServerCentral.com

The UNPIVOT operator does just the opposite of the PIVOT operator, which we looked at in the previous level. By using the PIVOT operator we can take multiple rows of data and create as single row as output. The UNPIVOT operator will take values from a single row and will create multiple rows. Microsoft introduced the UNPIVOT operator when they rolled out SQL Server 2005. In this level I will be showing you different examples of how to use the UNPIVOT operator. More »

How to use the SQL Prompt snippet placeholders for selecting and copying text

There are four SQL Prompt snippet placeholders that are all about selection and copying of text. These placeholders are very handy if, for example, you have two blocks of code that need to be part of a snippet. One part you hold on the clipboard, and the other part is a block of snippet text, selected using the $SELECTEDTEXT$ placeholder. More »

Question of the Day

Today's Question (by Steve Jones):

I have a dataframe called "sacks" that looks like this: 

 > sacks # A tibble: 5 x 5 Rank Player Sk Years Tm  1 1 "Bruce Smith+\\SmitBr00" 200 1985-2003 2TM 2 2 "Reggie White+\\WhitRe00" 198 1985-2000 3TM 3 3 "Kevin Greene+\\GreeKe00" 160 1985-1999 4TM 4 4 "Julius Peppers\\PeppJu99" 154 2002-2017 3TM 5 5 "Chris Doleman+\\DoleCh00" 150 1985-1999 3TM

I have a second data frame that looks like this: 

 > sacks2 # A tibble: 5 x 5 Rank Player Sk Years Tm  1 6 "Michael Strahan+\\StraMi02" 142 1993-2007 nyg 2 7 "Jason Taylor+\\TaylJa03" 140 1997-2011 3TM 3 8 "DeMarcus Ware\\WareDe99" 138 2005-2016 2TM 4 9 "Richard Dent+\\DentRi00" 138 1983-1997 4TM 5 NA "John Randle+\\RandJo00" 138 1990-2003 2TM

If I want to combine these into sacks1to10 as a single data frame with the same number of columns which command do I use?

Yesterday's Question of the Day

Yesterday's Question (by Mohammed Arshad):

When an index is rebuilt, does the fill factor apply permanently to the index until the next index rebuild?

Answer: No

Explanation:

The answer is no.

When an index is rebuilt, SQL server re-arranges the index pages as per the fill factor provided and fills only that amount of space on each  page. If no fill factor is set, the pages are filled. But the real catch is, SQL Server doesn't doesn't leave the free space configured in the fill factor for new pages that are required.

For example, if there are 80 pages in an index with fill factor 100% and it is rebuilt with a fill factor of 80%, SQL Server re-arranges all the 80 pages with 20% free space on each resulting in more total pages because now it has to leave 20% free space on all of them.

When a new transaction requires a new page, SQL Server doesn't apply the 80% fill factor for new pages allocated.
