Question

所以我创建了一个命中Dynamics GP Vendor表的存储过程。它需要能够在不同的数据库中访问同一个表。我看到的一种可能的解决方案就是用查询编写为varchar来执行参数。以下是存储过程中实际存在的代码：

Procedure [dbo].[DGP_addVendor]
@dbName varchar(4) = NULL
,@NoteIndex numeric(19,5) = NULL
,@VENDORID char(15) = NULL
, @VENDNAME char(65) = NULL
, @DEX_ROW_ID int = NULL output  
, @O_ErrorCode int = 0 output
, @ADDRESS1 char(61) = ''
, @ADDRESS2 char(61) = ''
, @ADDRESS3 char(61) = ''
, @CITY char(35) = ''
, @STATE char(29) = ''
, @ZIPCODE char(11) = ''
, @COUNTRY char(61) = ''
, @PHNUMBR1 char(21) = '' as

declare  @today datetime = convert(datetime,'01/01/1900')
declare  @defaultDate datetime = convert(datetime,'01/01/1900')
--declare @DEX int = null
Declare @sql varchar(MAX) = @dbName + '.dbo.zDP_PM00200SI

        EXEC(@sql)

以下是我用来调用它的代码：

exec [mdpSupportServices].[dbo].[DGP_addVendor] 'LFD', @index, 'ANT0000001','Anthony Quisenberry',@row out, @error out, '8506 west Rd', '','','Louisville', 'KY', '40247', 'USA',''

它似乎没有做任何事情。如果我做错了，那么有人能指出我更好的方向吗？

因此，此代码版本显示包含调试代码。请记住，连接空值将导致空值。

IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[DGP_addVendor]') AND type in (N'P', N'PC'))

Answer 2

您可以创建own system procedure。在master数据库中创建它，使用sp_前缀命名并标记为system one。结果，您可以从任何数据库中调用它，SP代码将访问调用数据库的对象。有可能但不推荐实现业务逻辑的方法。

另一种方法是使用动态SQL，正如您尝试的那样。这是一种更好的方式（从我的角度来看），但它自己有pros and cons。

使用变量数据库名称执行存储过程
