SQL

create procedure sp_get_report(@datefrom date=null,@dateto date=null,@customerfrom nvarchar(40)=null,@customerto nvarchar(40)=null,@salesrepfrom nvarchar(40)=null,@salesrepto nvarchar(40)=null)
as

begin

select total from employee where alldate between @datefrom and @dateto
and customer between @customerfrom and @customerto 
and sales between @salesrepfrom and @salesrepto

end

exec sp_get_report '2014-10-01','2014-10-03' -- if i did not pass @customerfrom,@customerto,@salesrepfrom,@salesrepto, i get null. becuase i used optional parameter for condition.

so if any set of between and condition is null, that particular betwenn and should not use.

we need use between and condition whatever is not null only. i guess it could be done using case any other way. but i am in learing process only.

if anyone knows, help me.

Solution 2

try this

SELECT
*
FROM employee e
WHERE (e.FromDate >= @datefrom
OR @datefrom IS NULL)
AND (e.ToDate < @dateto
OR @dateto IS NULL)

Solution 1

How about something along the lines of : ( alldate IS NULL OR alldate between @datefrom and @dateto )

i would just add a conditional statement to set dates to an absurd range when they are missing. i hate using greater than, less than in dates (for some reason)

ie...

SQL

create procedure sp_get_report(@datefrom date=null,@dateto date=null,@customerfrom nvarchar(40)=null,@customerto nvarchar(40)=null,@salesrepfrom nvarchar(40)=null,@salesrepto nvarchar(40)=null)
as

begin
if @datefrom is null set @datefrom = '1/1/1900'
if @dateto is null set @dateto = '1/1/2050'
etc...
select total from employee where alldate between @datefrom and @dateto
and customer between @customerfrom and @customerto
and sales between @salesrepfrom and @salesrepto

end
