列出SQL SERVER数据库中所有表及字段信息 lihonggen0（原作）
关键字 SQL,表,字段
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

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
注程序中须引用ActiveX Data Objects (ADO)
