Sql Server如何得到数据库中所有表的列表

[quote]csdn许多网友问怎样列出数据库有所有表及表信息，下面这段程序正是你所想要的[/quote]

程序思想:用SELECT name From sysobjects WHERE xtype = 'u'得到所有表，然后循环打开表,根据Rs_Colums.Fields(I).Name 得到字段名,FieldType(Rs_Colums.Fields(I).Type) 得到字段类型,Rs_Colums.Fields(I).DefinedSize '宽度

由于Rs_Colums.Fields(I).Type返回类型是数字，程序中写了一个FieldType函数转化成中文类型

Private Sub Command1_Click()
Dim Cn As New ADODB.Connection
Dim Rs_Table As New ADODB.Recordset
Dim Rs_Colums As New ADODB.Recordset

    With Cn   '定义连接
        .CursorLocation = adUseClient
        .Provider = "sqloledb"
        .Properties("Data Source").Value = "LIHG"
        .Properties("Initial Catalog").Value = "NorthWind"
        .Properties("User ID") = "sa"
        .Properties("Password") = "sa"
        .Properties("prompt") = adPromptNever
        .ConnectionTimeout = 15
        .Open

        If .State = adStateOpen Then
            Rs_Table.CursorLocation = adUseClient   '得到所有表名
            Rs_Table.Open "SELECT name From sysobjects WHERE xtype = 'u'", Cn, adOpenDynamic, adLockReadOnly
            Rs_Table.MoveFirst
            Do While Not Rs_Table.EOF
                Debug.Print Rs_Table.Fields("name")
                Rs_Colums.CursorLocation = adUseClient
                Rs_Colums.Open "select top 1 * from [" & Rs_Table.Fields("name") & "]", Cn, adOpenStatic, adLockReadOnly
                For I = 0 To Rs_Colums.Fields.Count - 1   ' 循环所有列
                    Debug.Print Rs_Colums.Fields(I).Name   '字段名
                    Debug.Print FieldType(Rs_Colums.Fields(I).Type)  '字段类型
                    Debug.Print Rs_Colums.Fields(I).DefinedSize  '宽度
                Next
                Rs_Colums.Close
                Rs_Table.MoveNext
            Loop
            Rs_Table.Close
            Set Rs_Colums = Nothing
            Set Rs_Table = Nothing

        Else
            MsgBox "数据库连接失败，请找系统管理员进行检查 ！", 16, cProgramName
            End
        End If
    End With
End Sub

            FieldType = "UNIQUEIDENTIFIER"
        Case 72
            FieldType = "VARBINARY"
        Case 204
            FieldType = "VARCHAR"
        Case 200
            FieldType = ""
    End Select
End Function

此程序只是一个雏形，可以在此基础上开发成一个工具使用

本程序在：VB 6.0 ，SQL SERVER 2000下运行通过
