sir this project is running from past 1 year where we can fetch date and time wise report through crystal report but now the task is to fetch using time frame like 6hrs or 24hrs...

hello friends., here I have an query which needs to pick up the complaint number which was not solved within the time frame like 6hours from the time that complaint was registered, and here i have 4coloumns saying compdate,comptime,forwardeddate,forwardedtime which are of nvarchar data type in the table urbrur means urban rural. So for this from the net i found one query i.e, "select compno from urbrur where forwardedtime>DATEADD(hour,6,@time)"; for that @time they used some fixed date time like Set @Time='09/16/2011 10:00:00' but here i can't use it because as in my table the date and time are in separate columns having datatype i.e, nvarchar and I don't want this type of fixed values, it should take the values from the date n time columns in the database . . So friends i think i gave an complete descrption to my query so kindly do concerned to my problem and give favorable reply . . I'm very thankful to u all, praveen
