现在要通过编程向B表中插入数据，可是在程序中是不允许给Int类型赋空值的如果不赋值就默认为0。
为了解决这个问题，用到了存储过程的If Else，下面是完整的存储过程。
代码示例:
代码如下:
create PROCEDURE [dbo].[P_Form_Control_Info_Add]
@TypeName varchar(20),
@Description varchar(50),
@CtlColSpan int,
@Sort int,
@SourceID int,
@FieldID int,
@TableID int
AS
if @SourceID = 0
begin
INSERT INTO T_Form_Control_Info (
[TypeName],
[Description],
[CtlColSpan],
[Sort],
[FieldID],
[TableID]
) VALUES (
@TypeName,
@Description,
@CtlColSpan,
@Sort,
@FieldID,
@TableID
)
end
else
begin
INSERT INTO T_Form_Control_Info (
[TypeName],
[SourceID],
@SourceID,
@TableID
)
end
return SCOPE_IDENTITY()

end

end
return SCOPE_IDENTITY()
