Hi,<br />
<br />
There is a table in SQL Server where it looks like that&gt;&gt;<br />
Account | &nbsp;MetricA | MetricB<br />
A1 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;33 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;|35<br />
B2 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;45 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;|31<br />
C3 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;32 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;|106<br />
<br />
How do i average those row level percentages <br />
See the attached excel.<br />
<br />
Select Account, MetricA, MetricB, (MetricA-MetricB)/MetricB as Change_PCT<br />
Will give me something below &gt;&gt;<br />
Account | &nbsp;MetricA | MetricB| Change_PCT<br />
A1 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;33 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;|35| -0.057142857<br />
B2 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;45 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;|31| 0.451612903<br />
C3 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;32 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;|106| -0.2<br />
<br />
<br />
If you average the change_PCT – it gives me 6.48%. How do I get that average of change_PCT in TSQL? Average of individual row level calculation?<br />
thank you<br />
