Query to find min/max date for when a list of items appeared in a table

Posted on 2007-11-16

Hello -

I have a table with name and dates in a table.   For each name I need to find the first and last date for which the name appears in the table.  I dont want to run any loops but for some reason can't warp my head around the query. I'll be storing the data in a temp table so if it's two queries and one as an update etc. thats fine.  I just want to avoid the performance hit of a loop or cursor.  


Name, First Date, Last Date

You could use MIN and MAX functions as:

SELECT YourNameField, MIN(YourDateField) FROM yourTable GROUP BY YourNameField
SELECT YourNameField, MAX(YourDateField) FROM yourTable GROUP BY YourNameField

Giving you something along the lines of:

 SELECT DISTINCT tbl.YourNameField, qry1.MaxDate, qry2.MinDate
  FROM YourTable tbl
  INNER JOIN (SELECT TEAM_Code_Home, MAX(MAT_Date) AS MaxDate FROM YourTable GROUP BY YourNameField) qry1 ON tbl.YourNameField = qry1.YourNameField
INNER JOIN (SELECT TEAM_Code_Home, MIN(MAT_Date) AS MinDate FROM YourTable GROUP BY YourNameField) qry2 ON tbl.YourNameField = qry2.YourNameField

Hope that helps,
