Question

对存储过程有疑问：
如何从声明为输出变量的存储过程中检索变量的值。运行程序为：

EXEC pn_investment_type_eqt {args}

这是存储过程：

create proc pn_investment_type_eqt
(
 @product_type varchar(10),
 @country varchar(10),
 @fi_treatment varchar(1)= '',
 @investment_type varchar(10) output,
 @investment_description varchar(50) output
)
as
 set nocount on

if @country <> 'US'
   select @country = 'FOREIGN'

if ( @fi_treatment not in ('Y','N') )
   select @fi_treatment = 'N'

if not exists(select 1 from d_investment_type_eqt
              where product_type = @product_type and isNull(country,'') = isNull(@country,'') and fi_treatment = @fi_treatment and row_status='A' )
begin
  select @country = 'ANY'
end

if exists ( select 1 from d_investment_type_eqt
            where product_type = @product_type and isNull(country,'') = isNull(@country,'') and fi_treatment = @fi_treatment and row_status='A' )
begin
   select @investment_type= investment_type , @investment_description = description
   from d_investment_type_eqt
   where product_type = @product_type and isNull(country,'') = isNull(@country,'') and fi_treatment = @fi_treatment and row_status='A'

end
 else
   return (-1)

我需要获得@investment_type＆amp;的值@investment_description

我无法更改程序。

我正在使用Spring 2.0的jdbcTemplate的自定义实现（sql，mapper，args）

数据库是Sybase

我如何从此存储过程中获得结果？

Answer 1

看一下这篇sybase-in-and-out-parameters帖子，它可能对你有所帮助。

Answer 2

我决定使用下一个设计：

declare @investment_type_value varchar(10)
declare @investment_description_value varchar(50)
SET @investment_type_value = '3041'

EXEC global..pn_investment_type_eqt 'CVPFDST', 'US', 'N', @investment_type = @investment_type_value output , @investment_description = @investment_description_value OUTPUT
select  investment_type = @investment_type_value, investment_description = @investment_description_value
GO

它使我有可能检索变量值。
