DAO: Adding a New Column to an Existing Table |
|
|
|
To programmatically add a new column, declare a
variable of type DAO.Field. After getting a reference to the table that will
receive the new column, assign the CreateField() method of the
table to the column's variable. Finally, call the Append() method
of the Fields collection of the table and pass it the column variable.
Here is an example:
|
Private Sub cmdAddColumn_Click()
Dim curDatabase As DAO.Database
Dim tblCustomers As DAO.TableDef
Dim colFullName As DAO.Field
' Get a reference to the current database
Set curDatabase = CurrentDb
' Get a reference to a table named Customers
Set tblCustomers = curDatabase.TableDefs("Customers")
Set colFullName = tblCustomers.CreateField("FullName", DB_TEXT)
tblCustomers.Fields.Append colFullName
End Sub
