Question

I want to write a stored procedure for the following SQL Server table:

No    Date          Days       Percentage
 1    17-Aug-12      2          -0.34%
 2    3-Aug-12       15         -29.39%
 3    27-Jul-12      22          12.02%
 4    20-Jul-12      29         -0.64%
 5    13-Jul-12      36         -3.45%
 6    6-Jul-12       43         -99.93%
 7    29-Jun-12      50          41.26%

Here I want to pass parameter to the percentage column or the days column dynamically.

Please help wite a stored procedure to select only percentages in a range say ‘12% – 15%’

Answer 1

To simply check against percentage…

CREATE PROCEDURE [GetPercentages]
( @Low INT, @High INT )
AS
BEGIN
    SELECT *
    FROM [MyTable]
    WHERE [Percentage] BETWEEN @Low AND @High
END

For more complex checking (where the table and/or fields are specified dynamically) then you could be looking at building a TSQL string to be run against sp_executesql.
