Open a new project in Visual Basic 5.0 or 6.0 Enterprise edition. Form1 is created by default.
Place the following controls on the form:
Control Name Text/Caption
-----------------------------------------
Button cmdGetEveryone Get Everyone
Button cmdGetOne Get One
From the Tools menu, select the Options item. Click the "Default Full Module View" option and then click OK. This will allow you to view all of the code for this project. Paste the following code into your code window:Option Explicit
Dim Cn As ADODB.Connection
Dim CPw1 As ADODB.Command
Dim CPw2 As ADODB.Command
Dim Rs As ADODB.Recordset

Go to the Project menu item and select References. Select the "Microsoft Active Data Objects 2.x Library." Run the project. When you click on the "Get Everyone" button, it executes this query:QSQL = "{call packperson.allperson({resultset 9, ssn, fname, "_

在最后,他们也是执行存取过程,返回一个记录集,这个和我的没有什么区别,区别在于他们使用的是表类型,但怎么返回大于32的字段(如long raw),msdn上没有说,我也不知道可以到以下:http://expert.csdn.net/Expert/topic/903/903782.xml?temp=.4693109
