VB中如何运行SQL语句

sql中有一个过程文件？？
我孤陋寡闻，没听说过。。。
是不是存储过程？
以下是vb访问存储过程的代码，从网上copy过来的。。。
Option Explicit
Dim mConn As ADODB.Connection
Dim rs1 As ADODB.Recordset
Dim rs2 As ADODB.Recordset
Dim rs3 As ADODB.Recordset
Dim rs4 As ADODB.Recordset
Dim cmd As ADODB.Command
Dim param As ADODB.Parameter
' 这里用第一种方法使用存储过程添加数据
Private Sub Command1_Click()
Set cmd = New ADODB.Command
Set rs1 = New ADODB.Recordset

cmd.ActiveConnection = mConn
cmd.CommandText = "insert_users"
cmd.CommandType = adCmdStoredProc

Set param = cmd.CreateParameter("truename", adChar, adParamInput, 20, Trim(txttruename.Text))

cmd.Parameters.Append param

Set param = cmd.CreateParameter("regname", adChar, adParamInput, 20, Trim(txtregname.Text))

cmd.Parameters.Append param

Set param = cmd.CreateParameter("pwd", adChar, adParamInput, 20
