dao default field value.

Full on code:

    Dim dbs As Database
    Dim fld As DAO.Field
    Set dbs = CurrentDb
    Set fld = dbs.TableDefs("YourTableName").Fields("YourFieldName")
    fld.DefaultValue = 0

    Set fld = Nothing
    Set dbs = Nothing

Short version:

CurrentDb("YourTableName").Fields("YourFieldName").DefaultValue = "SomeValue" ' text example

Does that append the field or just add the default data?
thx

Just adds the Default Value.

"But I would like to also provide a default value."

Also:

"Working in vb6."

You may need to use the OpenDatabase Method instead of CurrentDB.

Here I succeed in appending the field but then it does not do the default

Dim db As DAO.Database
Dim tb As DAO.TableDef
Dim fld As DAO.field

Set db = OpenDatabase(PassedPathNName, True)
Set tb = db.TableDefs("tblUserSettings")

      If tb.Fields.count < 17 Then '12-19-12 added
        Set fld = tb.CreateField("TruckRowHash", dbText) '
        tb.Fields.Append fld

'When it gets to this line it says "Field not found in this collection"
        Set fld = db.TableDefs("UserSettings").Fields("TruckRowHash")
        fld.DefaultValue = 0

    end if

thx

Dim dbs As DAO.Database
    Dim fld As DAO.Field
    Set dbs = OpenDatabase("YourDBName")
    Set fld = dbs.TableDefs("YourTableName").Fields("YourFieldName")
    fld.DefaultValue = 0 ' or whatever value
    dbs.Close
    Set fld = Nothing
    Set dbs = Nothing

Not sure what is going on ...  unless you have to Create the DefaultValue Property ... but I don't think so.

    Dim dbs As DAO.Database
    Dim fld As DAO.Field
    Set dbs = OpenDatabase("YourDBName")
    With dbs
        Set fld = .TableDefs("YourTableName").Fields("YourFieldName")
        fld.DefaultValue = 0 ' or whatever value
        .Close
    End With
    Set fld = Nothing
    Set dbs = Nothing

I'm afraid the use of "With dbs" did not help. It acts like the appended field is not really ready for action.  I guess I will just try some other way unless you have other ideas.
Thanks,

Try one or the other or both of the Refresh lines:


        Set fld = tb.CreateField("TruckRowHash", dbText) '
        tb.Fields.Append fld
       db.TableDefs.Refresh
        tb.Fields.Refresh

Found the problem, I had left off the "tbl" prefix I was using with my table.
Thanks for your perseverance and help.

I have to go, but ... If that did not work ... look up CreateProperty in vba Help ... and 'create' the DefaultValue property for that Field.

Also ... another approach is using the ALTER syntax ...
In fact ... see this:
https://www.experts-exchange.com/questions/23927409/'ALTER-TABLE-tblGLBudgetBalance-ALTER-COLUMN-intFiscalYear-NUMERIC-ADD-DEFAULT-WITH-0-'-What-syntax-wrong-in-statement-for-MS-Access.html?cid=295

Other Examples ... not directly related:

CurrentDb.Execute "ALTER TABLE tblGLBudgetBalance ALTER COLUMN  intFiscalYear number"

Public Function mChangeFieldType(sFld) As Boolean

    Dim tdf As TableDef, db As DAO.Database, fld As DAO.Field
    Set db = CurrentDb
    For Each tdf In db.TableDefs
        For Each fld In tdf.Fields
            If fld.Name = sFld Then
                If fld.Type = dbLong Then
                    CurrentDb.Execute "ALTER TABLE [" & tdf.Name & "] ALTER COLUMN " & sFld & " TEXT(55)"
                End If
            End If
        Next
    Next

I'm all set, it's working, thanks again.
