Going to need to back this up a bit. How do you know if something became a sale from the raw data?

Or are you looking for an in-line percentage like SUM(SAle)/SUM(Quote) AS PercentageConverted?

Craig,

I'm looking for the SUM(Sale)/SUM(Quote) WHERE Sale could be zero.

Thanks!

100.00 * Sum(Sale)/NULLIF(Sum(Quote), 0)

This makes sure that you are not performing integer division and also produces a null result when Sum(Quote) is zero.

The following does not right justify the percentage:

CAST(CONVERT(Decimal(9,2),ROUND(100.00 * Sum(Sale)/NULLIF(Sum(Quote), 0) ,2)) AS VARCHAR(6)) + '%'

NoSales

1.90%

11.11%

22.80%

5.71%

10.34%

The following does not right justify the percentage:

Justification is a presentation issue and should be handled by the presentation layer not in T-SQL.

No hate mail please.:hehe:

I thought that the following was interesting as listed in Jeff Moden's article that you posted in another thread: http://www.sqlservercentral.com/Forums/Topic1210948-338-1.aspx#bm1211028

http://www.sqlservercentral.com/articles/T-SQL/63681/

For most applications, that's good enough. If it's supposed to represent the final output,

we might want to make it a little prettier.

The STR function inherently right justifies, so we can use that to make the output a little prettier.

Please, no hate mail here! I'll be one of the first that formatting of this nature is supposed to be done in the GUI!

--===== We can use the STR function to right justify data and make it prettier.

-- Note that this should really be done by the GUI or Reporting Tool and

-- not in T-SQL

SELECT Year, STR(SUM(CASE WHEN Quarter = 1 THEN Amount

ELSE 0 END),5,1) AS [1st Qtr],

STR(SUM(CASE WHEN Quarter = 2 THEN Amount

ELSE 0 END),5,1) AS [2nd Qtr],

STR(SUM(CASE WHEN Quarter = 3 THEN Amount

ELSE 0 END),5,1) AS [3rd Qtr],

STR(SUM(CASE WHEN Quarter = 4 THEN Amount ELSE 0 END),5,1) AS [4th Qtr],

STR(SUM(Amount),5,1) AS Total

FROM #SomeTable1 GROUP BY Year
