方法1:
Dim adoConnectionX As New ADODB.Connection
Dim adoSchemaRecordsetX As New ADODB.Recordset
'Ms SQL 7:
'adoConnectionX.Open "Provider=SQLOLEDB.1;Persist Security Info=False;User ID=sa;Data Source=yuer;DataBase=NorthwindCS"
'Access 2000:
adoConnectionX.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=E:\DRptPlus\DRptPlus\Data\NWind2K.mdb;Persist Security Info=False"
Dim TestTableName As String
TestTableName = "产品"
Set adoSchemaRecordsetX = adoConnectionX.OpenSchema(adSchemaTables, Array(Empty, Empty, TestTableName, "Table"))
If Not adoSchemaRecordsetX.EOF Then
MsgBox "[" & TestTableName & "]表已存在!"
End If
方法2(引用Microsoft ADO Extensions 2.1 for DDL and Security (ADOX)):
（主持人注：需要升级至VB 6.0SP3）
Dim adoConnectionX As New ADODB.Connection
'Ms SQL 7:
adoConnectionX.Open "Provider=SQLOLEDB.1;Persist Security Info=False;User ID=sa;Data Source=yuer;DataBase=NorthwindCS"
'Access 2000:
'adoConnectionX.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=E:\DRptPlus\DRptPlus\Data\NWind2K.mdb;Persist Security Info=False"
Dim adoxCatalogX As New ADOX.Catalog
Set adoxCatalogX.ActiveConnection = adoConnectionX
Dim TestTableName As String
TestTableName = "产品"
Dim adoxTableX As ADOX.Table
For Each adoxTableX In adoxCatalogX.Tables
If adoxTableX.Name = TestTableName Then
MsgBox "[" & TestTableName & "]表已存在!"
Exit For
End If
Next
主持人注：方法2也可以这样：
Private Sub Command1_Click()
Dim cat As ADOX.Catalog
Dim tbl As ADOX.Table
Set cat = New ADOX.Catalog
Set cat.ActiveConnection = "Provider=Microsoft.Jet.OLEDB.3.51;" _
& "Data Source=C:\Program Files\Microsoft Visual Studio\VB98\Biblio.mdb"
On Error Resume Next
Set tbl = cat.Tables("MyTable")
If tbl Is Nothing Then
MsgBox "MyTable doesn't exist"
Else
MsgBox "MyTable exists"
Set tbl = Nothing
End If
Set cat = Nothing
Set con = Nothing
End Sub
方法三：
select * from sysobjects where name='TblName'
if rst.recordcount=0 then
不存在此表
else
存在
end if
