  Hi Friends,

  I have a table having some data where i want to generate sequence of rows based on premise value. I have given here the samples and the results that i am looking for..

  please give me your suggestions if there is any T-SQL can do this. Any suggestions would be really appreciated. Friends, If i am not making you clear, please let me know, i can brief you.

  select '12th Main St' as StreetName, 1 as FromPremise , 5 as ToPremise

  union

  select '10th Main St' as StreetName, 10 as FromPremise , 12 as ToPremise

  Sure you can do this pretty easily with a tally table.

  ;with MyData as

  (

  select '12th Main St' as StreetName, 1 as FromPremise , 5 as ToPremise

  union

  select '10th Main St' as StreetName, 10 as FromPremise , 12 as ToPremise

  )

  select StreetName, N as FromPremise, N as ToPremise

  from MyData d

  join Tally t on t.N between d.FromPremise and d.ToPremise

  order by StreetName, N
