Price Column is common in all tables

Final Output Is :

Table Query is
create Table Tbl_StartupBanner(ImageId int primary key identity(1,1) check(ImageId between 0 and 1), ImagePath nvarchar(Max) NOT Null, Price Money )
, Tbl_SignInBanner, Tbl_SignOutBanner Two table also same query But table name is changing.

I used this Query
Select sum(Tbl_StartupBanner.Price + Tbl_SignInBanner.Price + Tbl_SignOutBanner.Price) as Total from Tbl_StartupBanner,Tbl_SignInBanner,Tbl_SignOutBanner

Final Outpu: total : There is no record and emmty Displaying sir

Solution 2

try this if table has record but price is null

SQL

Select (ISNULL(Tbl_StartupBanner.Price,0) + ISNULL(Tbl_SignInBanner.Price,0) + ISNULL(Tbl_SignOutBanner.Price,0)) as Total from Tbl_StartupBanner,Tbl_SignInBanner,Tbl_SignOutBanner

if table has no records try this

SQL

SELECT(	(Select ISNULL(SUM(Tbl_SignOutBanner.Price),0) FROM Tbl_SignOutBanner) +
	(Select ISNULL(SUM(Tbl_SignInBanner.Price),0) FROM Tbl_SignInBanner)+
	(Select ISNULL(SUM(Tbl_StartupBanner.Price),0) FROM Tbl_StartupBanner)
      ) as total
