The MinID makes sense. I dropped the Date=Date and it works the same. thanks for the help.

Its an ugly hack but this works. SELECT * FROM TestEmp E LEFT OUTER JOIN (SELECT DL.DateItem,DL.ID,DL.EmpId,DL.Note FROM TestDateLog DL INNER JOIN (SELECT MIN(DATEADD(ms,ID,DateItem)) AS DateItem, EmpID FROM TestDateLog GROUP...

Well say note is a text field. ALTER TABLE TestDateLog ALTER COLUMN Note text NULL The text, ntext, and image data types are invalid in this subquery or aggregate expression. And what if there are more columns than just Note to be pulled from TestDateLog. Thanks for looking at it.

Employees Id Name 1 Joe 2 Carol 3 Susan DateLog ID date Employee Note 1 10-1 1 Fun 2 10-1 1 Great 3 10-10 3 monkeys rule 3 12-12 3 i like elephants So I want All employees with their earliest date applied, but also the...

Ok this looks like it works ALTER PROCEDURE ISODates @finddate datetime AS SET DATEFIRST 1 DECLARE @seed datetime DECLARE @firstdayyear datetime SET @seed = (SELECT DATEADD(yy,DATEDIFF(yy,'1/1/2000',@finddate),'1/1/2000')) SET @firstdayyear = (SELECT...

This is close. It messes up on the week for 12/29/2009, 1 instead of 53. ALTER PROCEDURE ISODates @finddate datetime AS SET DATEFIRST 1 DECLARE @seed datetime SET @seed = (SELECT DATEADD(yy,DATEDIFF(yy,'1/1/2000',@finddate),'1/1/2000')) SELECt DATEPART(yy...

FYI: we dont have daylight savings where I live ... along the daylight saving thing what happens in the time that that occurs. Say that 2Am (or whenever daylight saving starts) you make some records 4-1-2004 2.00.01 am 4-1-2004 2.01.01 am 4-1-2004 2.02.01 am 4-1-2004 2.03.01 am then at...

Why does the second one not work. Is it because the IN function goofs on the null or what?

von, you write some quick stuff CREATE PROCEDURE County_pwilson AS Declare @StartTime DateTime Declare @MidTime DateTime Declare @EndTime DateTime Declare @EndTime2 DateTime Set @StartTime = GetDate() DECLARE @maxpoint int SELECT @maxpoint = MAX(PointNumber) FROM MapPoints Set @EndTime =...

I figured that one out after I posted. I did the algorithm wrong. Ok now im down to 3754 in 13.36

I am getting 3854. Are there 1464 MapPoints and 4166 Locations?

In researching how to do it I found one that does most of what was asked. Didnt want to plagiarize or redo it.

My eratosthenes took about 10 secs longer than that replacing the Join part with DECLARE @i int SET @i = 2 WHILE @i < SQRT(@NumRows) BEGIN DELETE FROM #t WHERE RowNum%@i=0 AND RowNum > @i SET @i = (SELECT MIN(RowNum) FROM #t where RowNum>@i) END

Here is mine Found the Table generation from this site. Modded it to be from n^2 to n^n with a limit so i wouldnt be joining 100000 twice. #t is numbers 1 to @NumRows #j is numbers 1 to SQRT(@NumRows) This is because of the following in the list 1,2,3,4,5,6 if you delete the multiples of 2...

On a Sybase app I was creating a package that pulled some random numbers. so i did something like SELECT Rand(Column * (datepart(ms,getdate())) Well on sybase the seed you pass in there is a global seed. There was a row with a zero causing the rand(0) = 0. Since Sybase sets the seed to a...
