As you can see from above, none of the names gave a complete indication of what the index encompassed. The first one did indicate it was a Non Clustered Index so that was good, but includes the date which to me is not needed. At least I knew it was not a Clustered Index. The second index did note it is a “Covering Index” which gave some indication that many columns could be included I also know it was created with the Data Tuning Advisor due to the dta prefix. The third index was also created with dta but it was left with the default dta naming convention. Like the first one I know the date it was created but instead of the word Cover2, I know there are 16 key columns are noted by the “K#” and regular numbers tell me those are included columns. However, I still have no idea exactly what these numbers denote without looking deeper into the index. The last index is closer to what I like however the name only tells me one column name when in fact it encompasses five key columns and two included columns.
I absolutely love seeing lots and lots of “_dta_” indexes; it’s a sign that I have a long day ahead of me.
