我最终解决了这个问题。（我现在使用的是 Access 2007，但遇到了与 Access 2003 相同的问题。）
首先，什么不起作用：
即使使用格式正确的 schema.ini，TransferText 也只会使标题行 unicode 和波浪号分隔。（不，我没有把它全部放在一行上，这只是 stackoverflow 上 html 的格式问题。）
[MyTable.txt]
CharacterSet = Unicode
Format = Delimited(~)
ColNameHeader = True
NumberDigits = 10
Col1= "Col1" Char Width 10
Col2= "Col2" Integer
Col3= "Col3" Char Width 2
只需使用 select 语句：
SELECT * INTO [Text;DATABASE=c:\export\;FMT=Delimited(~)].[MyTable.txt] FROM [MyTable]
完全忽略了 FMT。我发现很难找到有关参数格式的文档。无论我在 FMT 参数中输入什么，我唯一能开始工作的就是 Fixed。其他所有内容都被视为 CSVDelimited。我可以检查这一点，因为 select 语句创建了一个 schema.ini 文件，如下所示：
[MyTable.txt]
ColNameHeader=True
CharacterSet=1252
Format=CSVDelimited
Col1=Col1 Char Width 10
Col2=Col2 Integer
Col3=Col3 Char Width 2
我最终的解决方案是创建自己的 schema.ini，然后使用 select 语句。我的模块代码如下所示：
Option Compare Database
Option Explicit
Public Function CreateSchemaFile(bIncFldNames As Boolean, _
sPath As String, _
sSectionName As String, _
sTblQryName As String) As Boolean
Dim Msg As String
On Local Error GoTo CreateSchemaFile_Err
Dim ws As Workspace, db As Database
Dim tblDef As TableDef, fldDef As Field
Dim i As Integer, Handle As Integer
Dim fldName As String, fldDataInfo As String
' -----------------------------------------------
' Set DAO objects.
' -----------------------------------------------
Set db = CurrentDb()
' -----------------------------------------------
' Open schema file for append.
' -----------------------------------------------
Handle = FreeFile
Open sPath & "schema.ini" For Output Access Write As #Handle
' -----------------------------------------------
' Write schema header.
' -----------------------------------------------
Print #Handle, "[" & sSectionName & "]"
Print #Handle, "CharacterSet = Unicode"
Print #Handle, "Format = Delimited(~)"
Print #Handle, "ColNameHeader = " & _
IIf(bIncFldNames, "True", "False")
Print #Handle, "NumberDigits = 10"
' -----------------------------------------------
' Get data concerning schema file.
' -----------------------------------------------
Set tblDef = db.TableDefs(sTblQryName)
With tblDef
For i = 0 To .Fields.Count - 1
Set fldDef = .Fields(i)
With fldDef
fldName = .Name
Select Case .Type
Case dbBoolean
fldDataInfo = "Bit"
Case dbByte
fldDataInfo = "Byte"
Case dbInteger
fldDataInfo = "Short"
Case dbLong
fldDataInfo = "Integer"
Case dbCurrency
fldDataInfo = "Currency"
Case dbSingle
fldDataInfo = "Single"
Case dbDouble
fldDataInfo = "Double"
Case dbDate
fldDataInfo = "Date"
Case dbText
fldDataInfo = "Char Width " & Format$(.Size)
Case dbLongBinary
fldDataInfo = "OLE"
Case dbMemo
fldDataInfo = "LongChar"
Case dbGUID
fldDataInfo = "Char Width 16"
End Select
Print #Handle, "Col" & Format$(i + 1) _
& "= """ & fldName & """" & Space$(1); "" _
& fldDataInfo
End With
Next i
End With
CreateSchemaFile = True
CreateSchemaFile_End:
Close Handle
Exit Function
CreateSchemaFile_Err:
Msg = "Error #: " & Format$(Err.Number) & vbCrLf
Msg = Msg & Err.Description
MsgBox Msg
Resume CreateSchemaFile_End
End Function
Public Function ExportATable(TableName As String)
Dim ThePath As String
Dim FileName As String
Dim TheQuery As String
Dim Exporter As QueryDef
ThePath = "c:\export\"
FileName = TableName + ".txt"
CreateSchemaFile True, ThePath, FileName, TableName
On Error GoTo IgnoreDeleteFileErrors
FileSystem.Kill ThePath + FileName
IgnoreDeleteFileErrors:
TheQuery = "SELECT * INTO [Text;DATABASE=" + ThePath + "].[" + FileName + "] FROM [" + TableName + "]"
Set Exporter = CurrentDb.CreateQueryDef("", TheQuery)
Exporter.Execute
End Function
Sub ExportTables()
Dim lTbl As Long
Dim dBase As Database
Dim TableName As String
Set dBase = CurrentDb
For lTbl = 0 To dBase.TableDefs.Count - 1
'If the table name is a temporary or system table then ignore it
If Left(dBase.TableDefs(lTbl).Name, 1) = "~" Or _
Left(dBase.TableDefs(lTbl).Name, 4) = "MSYS" Then
'~ indicates a temporary table
'MSYS indicates a system level table
Else
TableName = dBase.TableDefs(lTbl).Name
ExportATable (TableName)
End If
Next lTbl
Set dBase = Nothing
End Sub
我没有声称这很优雅，但它确实有效。另请注意，stackoverflow 代码格式化程序不喜欢我的 \"，因此它不能很好地打印我的代码。
