本文展示了一个使用ASP.NET进行数据库操作的例子，包括连接数据库、声明执行存储过程、获取输出参数以及通过不同方式从数据库中选择数据。示例中详细说明了如何构建SQL语句并执行，以及如何解析结果集并显示到表格中。

dim conn
dim strconn
dim rs
dim strsql
dim strsql2
dim strsql3
dim strsql4
dim strsql5
dim strsql6
dim strsql7
dim strsql8

'strconn = Driver={SQL Server};Description=example;SERVER=222.222.1.2;UID=webexample;PWD=;DATABASE=webexample"

'Format Declare & EXEC statements that will be passed
'to the database with the output parameters
strsql = "DECLARE " & CHR(10) & "@Id_Req " & "INT" & CHR(10)
strsql2 ="exec " & "sp_EmpInfo" & " '" & request("txtFirstName") & "'," & "'" & request("txtLastName") & "', " & "'" & request("txtaddress") & "', " & "'" & request("txtcity") & "', "& "@Id_Req " & "OUTPUT" & chr(10)

'Formats one or more sql statements that will be passed to the
'database In this examples I use six different ways.
strsql3 ="SELECT * FROM AllData WHERE RecordId = @Id_Req" & Chr(10)
strsql4 ="SELECT AllData.fname, AllData.lname FROM Alldata WHERE RecordId = @Id_Req" & Chr(10)
strsql5 ="SELECT AllData.fname FROM AllData WHERE RecordId = @Id_Req" & Chr(10)
strsql6 ="SELECT AllData.lname FROM AllData WHERE RecordId = @Id_Req" & Chr(10)
strsql7 ="SELECT AllData.Address FROM AllData WHERE RecordId = @Id_Req" & Chr(10)
strsql8 ="SELECT AllData.city FROM AllData WHERE RecordId = @Id_Req" & Chr(10)

'Puts together all of the local variables into one variable
'That will be used by the recordset object
strsql = strsql & strsql2 & strsql3 & strsql4 & strsql5 & strsql6 & strsql7 & strsql8

'This is optional this writes out the strsql local variable
'that will be passed to the database
response.write "" & "Sql Statement that is passed to the database" & "" & "
"
response.write strsql & "
" & "
"

'sets a connection & recordset objects and executes the strsql local variable
set conn = server.createobject("adodb.connection")
conn.open strconn
set rs = server.createobject("adodb.recordset")
rs.open strsql, conn

'Parses out the individual recordsets and places them
'into individual table rows
intcount = 1
Do Until rs Is Nothing
response.write "

response.write " Contents of recordset #" & intCount & "
"
'Parses out the individual recordsets and places them into table rows
Do While Not rs.EOF
response.write "

"
For Each oField In RS.Fields
response.write "" & oField.Name & ""
Next
Response.write "" & ""
For Each oField In RS.Fields
response.write ""
If IsNull(oField) Then
Response.Write " "
Else
Response.Write oField.Value
End If
response.write ""
Next
rs.MoveNext
Loop
'Uses the NEXTRECORDSET Method
Set rs = rs.NextRecordset
intCount = intCount + 1
response.write ""
Loop
%>
