Hi all

i have to set one flage based on 4 different values in sql.

here is my code

SQL

DECLARE @Flag int ,
		@Count1 int 	,
		@Count2 int 	,
		@Count3 int 	,
		@Count4 int ,
                @ShippingLineID	int
	select @Count1 =   COUNT(ContainerID) from tbl_CMS_Container where ShippingLine = @ShippingLineID
	
	select @Count2 =   COUNT(EmptyContainerID) from tbl_CMS_Empty_Container where ShippingLine = @ShippingLineID
	select @Count3 =   COUNT(ExportContainerID) from tbl_CMS_Export where ShippingLine = @ShippingLineID
	
	select @Count4 =   COUNT(GatePassId) from tbl_CMS_GatePass where ShippingLine = @ShippingLineID

now if any of the count is > 0 then @flag should be 1. else @flag should be 0. in short flag should be 0 if all the counts are 0 or null. otherwise it should be 1.

Use the below query. We can directly use the sum of all the counts becuase count will be either 0 or greater than 0.

DECLARE @Flag int ,
@Count1 int ,
@Count2 int ,
@Count3 int ,
@Count4 int ,
@ShippingLineID int

select @Count1 = COUNT(ContainerID) from tbl_CMS_Container where ShippingLine = @ShippingLineID
select @Count2 = COUNT(EmptyContainerID) from tbl_CMS_Empty_Container where ShippingLine = @ShippingLineID
select @Count3 = COUNT(ExportContainerID) from tbl_CMS_Export where ShippingLine = @ShippingLineID
select @Count4 = COUNT(GatePassId) from tbl_CMS_GatePass where ShippingLine = @ShippingLineID

SET @Flag = @Count1 + @Count2 + @Count3 + @Count4
