使用refcursor通过VBA调用Oracle存储过程

Sub CallOracleProcedure()
    Dim conn As Object
    Dim cmd As Object
    Dim rs As Object
    Dim param As Object
    
    ' 创建数据库连接
    Set conn = CreateObject("ADODB.Connection")
    conn.ConnectionString = "Provider=OraOLEDB.Oracle;Data Source=your_database;User ID=your_username;Password=your_password;"
    conn.Open
    
    ' 创建命令对象
    Set cmd = CreateObject("ADODB.Command")
    cmd.ActiveConnection = conn
    cmd.CommandType = 4 ' adCmdStoredProc，表示执行存储过程
    
    ' 设置存储过程名称
    cmd.CommandText = "your_procedure_name"
    
    ' 创建refcursor参数
    Set param = cmd.CreateParameter("p_cursor", 9, 2, , Null)
    param.Direction = 2 ' adParamOutput，表示输出参数
    cmd.Parameters.Append param
    
    ' 执行存储过程
    Set rs = cmd.Execute
    
    ' 获取结果集
    Do While Not rs.EOF
        ' 处理结果集数据
        ' ...
        
        rs.MoveNext
    Loop
    
    ' 关闭连接
    rs.Close
    conn.Close
End Sub
