    - by the_drow
    Usually declaring variables on assignment is considered a best practice in VBScript or JavaScript , for example, although it is allowed.

How would you avoid such a situation?

  • SQL Server 2000: Why is this query w/ variables so slow vs w/o variables?

    I can't figure out why this query would be so slow with variables versus without them. I read some where that I need to enable "Dynamic Parameters" but I cannot find where to do this. DECLARE @BeginDate AS DATETIME ,@EndDate AS DATETIME SELECT @BeginDate = '2010-05-20' ,@EndDate = '2010-05-25' -- Fix date range to include time values SET @BeginDate = CONVERT(VARCHAR(10), ISNULL(@BeginDate, '01/01/1990'), 101) + ' 00:00' SET @EndDate = CONVERT(VARCHAR(10), ISNULL(@EndDate, '12/31/2099'), 101) + ' 23:59' SELECT * FROM claim c WHERE (c.Received_Date BETWEEN @BeginDate AND @EndDate) --this is much slower --(c.Received_Date BETWEEN '2010-05-20' AND '2010-05-25') --this is much faster
