Step back and think about the data in a complete set rather than 30 loops.

You have a query that retrieves one day's worth of data, and you want a month's worth, so you are attempting to reuse the 'day' query for the number of days in the month. Don't do it. Write the query to retrieve the data you want, for example

 select * from tble where date between '01-nov-16' and '30-nov-16'

OK. But you might say that you don't always want a complete month. You might want 20 days worth of data starting from some given start date! Again, describe the result set....

 declare @startdate date
 set @startdate = '19 October 2016'

 select * from tble where date between @startdate and dateadd(day, 20, @startdate)

And from this you could even make the 'number of days' a parameter.....

But always describe the result set you want SQL to return, rather than describing how to get the results.

Thanks Man, Well the problem is. i do not have the liberty to query data more then 1 days, because one day worth data returns 5 Million or rows even after grouping, and i need to insert that 5 million of rows to a different table and this needs to be done for 180 days [6 Month].

Querying on Multiple Date slows down the query since indexing is being done on date column.
