SET QUOTED_IDENTIFIER ON
SET ANSI_NULLS ON
GO CREATE proc [dbo].[is_yy]
@return_value varchar(2) out,
@p1 varchar(20),
@p2 varchar(50)
as
begin
if @p1=''
begin
SET @return_value = ''
RETURN @return_value
end
if @p2=''
begin
SET @return_value = ''
RETURN @return_value
end end GO
存储过程如上,执行如下:
DECLARE @return_value1 VARCHAR(50)
EXEC @return_value1 =is_yy '', '',''
SELECT @return_value1 DECLARE @return_value2 VARCHAR(50)
EXEC @return_value2 =is_yy '', '',''
SELECT @return_value2
执行结果如下:
