Change field names to first row of table

[Bob]

Hi all,

I've got a table that I've imported and it has junk at the top of the
table, so after import I run a delete query to remove the junk lines
then I'm left with the field names I want for the table at the top of
the table but the field names currently are 'field1' etc, so how do I
rename the field names to the fields on the top row of the table.

Cheers,

Bob

Actually, to add to that I would like to change the fieldname to the
first Row of the table + the second. So for example...

Field1 Field2 Field3
Customer Customer Customer
ID Name Street Address
12321 David Park 452 Walker Ln
12455 etc

so for this example I want Field1 to equal 'Customer ID' and field2 to
equal 'Customer Name' then delete the first two rows so there's only
the actual data left....

If the column names were all in the first row, you could specify that in the
Import Wizard, and not have to do any post-processing. It is a little
unusual for the Column Headings to be split over two rows, but you could
write VBA code to do what you want, after you have imported the information
into a table; or, perhaps, depending on the format of the data that is being
imported, before or as you import it.

I see two potential wrinkles here:

1. Since tables are unordered, you'll need to let Access add its own
Autonumberprima ry key (named [ID]) during the import so you can
determine with certainty what the "first two" rows of the table are.

2. There would be problems with trying to change the column names
while the table is open. My approach would be iterate through the
columns to determine their new names, save them in a Dictionary
object, then close the recordset and alter the column names via a
TableDef object.

So, for my test table...

ID Field1 Field2 Field3
1 Customer Customer Customer
2 ID Name Street Address
3 12321 David Park 452 Walker Ln
4 12455 Mike McMack 750 Virago St

....I would do something like this:

Sub TableFix()
' requires references to:
' - Microsoft DAO
' - Microsoft Scripting Runtime
Dim cdb As DAO.Database, rst As DAO.Recordset, _
tbd As DAO.TableDef, fld As DAO.Field
Dim NewFieldNames As New Dictionary, strNewName As String
Dim OldName As Variant

Const TblName = "Foo"

Set cdb = CurrentDb
Set rst = cdb.OpenRecords et( _
"SELECT * FROM [" & TblName & "] " & _
"WHERE [ID]<=2 " & _
"ORDER BY [ID]", _
dbOpenSnapshot)

For Each fld In rst.Fields
OldName = fld.Name
If OldName <"ID" Then
strNewName = ""
Do While Not rst.EOF
strNewName = strNewName & rst(OldName).Va lue & " "
rst.MoveNext
Loop
NewFieldNames.A dd OldName, Trim(strNewName )
rst.MoveFirst
End If
Next
rst.Close
Set rst = Nothing
Set fld = Nothing

Set tbd = cdb.TableDefs(T blName)
For Each OldName In NewFieldNames
tbd.Fields(OldN ame).Name = NewFieldNames(O ldName)
Next
Set tbd = Nothing
Set NewFieldNames = Nothing

cdb.Execute _
"DELETE * FROM [" & TblName & "] " & _
"WHERE [ID]<=2", _
dbFailOnError
Set cdb = Nothing
End Sub

Hi Bob,

Here's an *idea*...

1.) Create a properly structured "Template" table with an AutoNumber field,
correct field names / data types ...etc.
2.) Make a copy of the "template" table, renaming it to the "good" table
that you want to use for your forms and reports, etc.
3.) Design an append query that filters out the junk, and appends the good
data.
4.) When it comes time to refresh the data from a new import file ... delete
your "good" table, make a new copy of the "template" (as in step 2 above)

Here's a code sample (long) that will hopefully explain how I have automated
the entire import process.
What used to take an hour to do now takes just seconds, so this strategy
will be worth the time investment (IMHO)

This code also calls a couple of custom functions and subs that I have
designed, but not included. Many of the variable are declared in the form
declaration section as they are used by multiple procedures.

If you're REALLY interested, let me know ... and I'll post (or e-mail) them
as well.

Hi all,

I've got a table that I've imported and it has junk at the top of the
table, so after import I run a delete query to remove the junk lines
then I'm left with the field names I want for the table at the top of
the table but the field names currently are 'field1' etc, so how do I
rename the field names to the fields on the top row of the table.

Cheers,

Bob
