Description
I'm doing some testing against the Stack Overflow database with Columnstore indexes and the parsing isn't working properly. My statistics are at the bottom of this bug for reproduction purposes.
The columns displayed by the tool are;
- Scan Count
- Logical Reads
- Physical Reads
- Read-Ahead Reads
- LOB Logical Reads
- LOB Physical Reads
- LOB Read-Ahead Reads
The columns that my statistics have are here;
- Scan Count (32)
- Logical Reads (0)
- Physical Reads (0)
- Page Ahead Reads (0)
- Read-Ahead Reads (0)
- Page Server Read-Ahead Reads (0)
- LOB Logical Reads (1448751)
- LOB Physical Reads (9)
- LOB Page Server Reads (0)
- LOB Read-Ahead Reads (1355388)
- LOB Page Server Read-Ahead Reads (0)
When being displayed, it's only showing the "Scan Count: 32" field, everything else is zero (and the "% Logical Reads of Total Reads" returns NaN).
I don't have the skills to push a fix for this myself but if anybody else has time to fix or to point out what I'm doing wrong it would be greatly appreciated.
