PRB: Jet Text IISAM Truncates Trailing Spaces
ID: Q182355
|
The information in this article applies to:
-
Microsoft Visual Basic Professional and Enterprise Editions for Windows, version 5.0
-
Microsoft Visual Basic for Applications version 5.0
-
Microsoft Access 97
SYMPTOMS
When importing delimited data from a text file into a Jet database,
trailing spaces are dropped from fields.
CAUSE
The Text IISAM driver truncates trailing spaces regardless of whether the
field is surrounded by quotes.
RESOLUTION
- Write a custom import routine using low-level file I/O and DAO, and
parse the line into fields using BASIC.
-or-
- When creating the text file, use a substitute character for trailing
spaces you do not want truncated and then use a SQL statement to "fix"
the imported data.
STATUS
This behavior is by design.

Steps to Reproduce Behavior
- Using Notepad, create a text file with the following data:
ID,Desc,Field3
Line1,Description 1 ,Field3-1
Line2,"Description 2 ",Field3-2
- Save the file as c:\test.txt.
- In Visual Basic, create a new project and add a reference for Microsoft
DAO 3.5 Object Library. In Access, open the Northwind.MDB database.
- Create a new form with a CommandButton (Command1) and the following
code:
Private Sub Command1_Click ()
Dim db As Database
Set db = CurrentDB ' Access only
Set db = DBEngine(0).OpenDatabase("biblio.mdb") ' Visual Basic
db.Execute "SELECT * INTO TestImport FROM [test#txt] IN '' " _
"'text;database=c:\;FMT=Delimited;HDR=Yes'"
db.Close
End Sub
- Run the project/form and click the CommandButton to import the data.
- Examine the contents of the TestImport table, and note that the Desc
column has the trailing spaces truncated for both records.
Notes:
- The symptoms are also present when using Access' File|Get External Data
menu command and via the TransferText macro action and the TransferText
method of the DoCmd object, all of which use the Text IISAM driver.
- The symptoms probably also apply to previous versions of Jet but have
not been tested with them.
- In Visual Basic, you can use the VISDATA sample project to examine the
contents of the table.
