Thanks for sharing this out.
This is interesting that I can speed up by adding index to the table.

Thumbs up for this!

Hello Hans-Jörg Mayr,

Thank you for your comment and question.

Performance wise, for that scenario, considering the number of rows being around 500k and only a small percentage of values in that column are equal (more or less 10%). With an index we will have first queries around 2 ms and subsequent ones around 0ms. And creating this new index we had an increase in the index_size for this table of around 29000 KB.

King regards
Gonçalo Melo

Very interesting article!
But what i miss is the comparison to the explicit column [PhoneNUmberCopy] with an index for the column.
How ist the performance and the cost of the query in that Scenario?

Regards
Hans-Jörg
