如何在MS Access中获取表的列名?

8

如何使用查询在MS Access中获取表的字段名或列名?

有人可以帮助我解决这个问题吗?

比如,如果我有一个名为“employee”的表,我需要获取员工的字段名(如id、name、workstatus等),而不是它的记录...有没有方法可以做到这一点?

谢谢

以下是我以前用来跟踪审计等事项的一些代码,我不能为此而自豪,因为我很久以前就在网上找到了它。

Sub GetField2Description()
'**********************************************************
'Purpose:   1) Deletes and recreates a table (tblFields)
'           2) Queries table MSysObjects to return names of
'              all tables in the database
'           3) Populates tblFields
'Coded by:  raskew
'Inputs:    From debug window:
'           Call GetField2Description
'Output:    See tblFields
'**********************************************************

Dim db As Database, td As TableDef
Dim rs As Recordset, rs2 As Recordset
Dim Test As String, NameHold As String
Dim typehold As String, SizeHold As String
Dim fielddescription As String, tName As String
Dim n As Long, i As Long
Dim fld As Field, strSQL As String
n = 0
Set db = CurrentDb
' Trap for any errors.
    On Error Resume Next
tName = "tblFields"

'Does table "tblFields" exist?  If true, delete it;
docmd.SetWarnings False
   docmd.DeleteObject acTable, "tblFields"
docmd.SetWarnings True
'End If
'Create new tblTable
db.Execute "CREATE TABLE tblFields(Object TEXT (55), FieldName TEXT (55), FieldType TEXT (20), FieldSize Long, FieldAttributes Long, FldDescription TEXT (20));"

strSQL = "SELECT MSysObjects.Name, MSysObjects.Type From MsysObjects WHERE"
strSQL = strSQL + "((MSysObjects.Type)=1)"
strSQL = strSQL + "ORDER BY MSysObjects.Name;"

Set rs = db.OpenRecordset(strSQL)
If Not rs.BOF Then
   ' Get number of records in recordset
   rs.MoveLast
   n = rs.RecordCount
   rs.MoveFirst
End If

Set rs2 = db.OpenRecordset("tblFields")

For i = 0 To n - 1
  fielddescription = " "
  Set td = db.TableDefs(i)
    'Skip over any MSys objects
    If Left(rs!Name, 4) <> "MSys" And Left(rs!Name, 1) <> "~" Then
       NameHold = rs!Name
       On Error Resume Next
       For Each fld In td.Fields
          fielddescription = fld.Name
          typehold = FieldType(fld.Type)
          SizeHold = fld.Size
          rs2.AddNew
          rs2!Object = NameHold
          rs2!FieldName = fielddescription
          rs2!FieldType = typehold
          rs2!FieldSize = SizeHold
          rs2!FieldAttributes = fld.Attributes
          rs2!FldDescription = fld.Properties("description")
          rs2.Update
       Next fld

       Resume Next
    End If
    rs.MoveNext
Next i
rs.Close
rs2.Close
db.Close
End Sub

Function FieldType(intType As Integer) As String

Select Case intType
    Case dbBoolean
        FieldType = "dbBoolean"    '1
    Case dbByte
        FieldType = "dbByte"       '2
    Case dbInteger
        FieldType = "dbInteger"    '3

        FieldType = "dbSingle"     '6
    Case dbDouble
        FieldType = "dbDouble"     '7
    Case dbDate
        FieldType = "dbDate"       '8
    Case dbBinary
        FieldType = "dbBinary"     '9
    Case dbText
        FieldType = "dbText"       '10
    Case dbLongBinary
        FieldType = "dbLongBinary" '11
    Case dbMemo
        FieldType = "dbMemo"       '12
    Case dbGUID
        FieldType = "dbGUID"       '15
End Select

End Function
