Dear All, Plz help me in optimising the following query,
Reduce repeatable reads from the table via select ,ythe table sare not
having referntial integrity constarints ,relations
CREATE proc Rolex136Sync
as
DECLARE @date varchar(50),@ydate varchar(50)
print CONVERT(char(11),(GETDATE()-1),100)
SET @date =
substring(CONVERT(char(11),(GETDATE()),100),5,2)+'-'+substring(CONVERT(char(11),(GETDATE()),100),1,3)+'-'+substring(CONVERT(char(11),(GETDATE()),100),8,4)
SET @ydate =
substring(CONVERT(char(11),(GETDATE()-1),100),5,2)+'-'+substring(CONVERT(char(11),(GETDATE()-1),100),1,3)+'-'+substring(CONVERT(char(11),(GETDATE()-1),100),8,4)
Print @date
Print @ydate
