Hi Experts,

Create View VWCurrentGgl

as


Select GlYear, GlPeriod,'' as AccountType, '' as ExpenseType, Company, '' as GlCode, '' as Description,0 as PeriodMovement
from dbo.GenControl

Union all

Select Convert(Int,'') as GlYear, Convert(Int,'') as GlPeriod ,AccountType, ExpenseType, Company,GlCode, Description, CurrentBalance - PrevPerEndBal  As PeriodMovement
from dbo.GenMaster

The Results are the screen shot attached...

How can i get the GlYear and GlPeriod to populate all the way down as opposed to the zero's (if I need to change my thinking from a view to something else please let me know and assist)

i'm not sure what the point of the first record is if it has no relation. There has to be some calculation or reasoning for knowing what year and period to display. Maybe a stored procedure would be better?

@Year int
@Period int

Select @Year as GlYear, @Period as GlPeriod,AccountType, ExpenseType, Company,GlCode, Description, CurrentBalance - PrevPerEndBal  As PeriodMovement
from dbo.GenMaster

Basing my results on that the GenControl table appears to have a single record, you should join the 2 tables rather than unioning them:

Select gc.GlYear, gc.GlPeriod, gm.AccountType, gm.ExpenseType, gm.Company, gm.GlCode, gm.Description, gm.CurrentBalance - gm.PrevPerEndBal  As PeriodMovement
from dbo.GenMaster gm
INNER JOIN dbo.GenControl gc ON 1 = 1  --Dummy join

OR

Select (SELECT glYear FROM dbo.GenControl) AS GlYear,
       (SELECT GlPeriod FROM dbo.GenControl) as GlPeriod,
       AccountType, ExpenseType, Company, GlCode, Description, CurrentBalance - PrevPerEndBal  As PeriodMovement
from dbo.GenMaster
