I am using ADOX (on Windows 2000) to create a new table in my database.

One of the columns must have a default for each new record so I wish to
populate the default dynamic property.

However, I cannot do this because when I try to set the value of the
default property I am told the data type is wrong (it is expecting
adVariant)

Set adoxCatalog.ActiveConnection = ADOCon
Set adoxTable = New adox.Table
adoxTable.Name = "MyNewTable"

Set adoxCol = New adox.Column
Set adoxCol.ParentCatalog = adoxCatalog
       
adoxCol.Name = "MyNewColumn"
adoxCol.Type = adInteger
adoxCol.Attributes = adColFixed
adoxCol.Properties("Default").Value = 0   ' this line fails
adoxTable.Columns.Append adoxCol

Only two things come to mind. First, try:

adoxCol.Properties("Default").Value = CVar(0)

since the default property is supposed to expect a variant and perhaps it has a hard time with literal integer.

On the second issue, I may be off-base, but I thought the adColFixed attribute was only for use on character fields whose width can vary.  Since you have an integer field here, perhaps you should just try commenting that line out.

What version of ADOX are you using?  I never got the data type error complaint until I executed the cat.Tables.Append statement - and then had to visit the data type of every column to try and figure out which one caused the problem.  This is pretty nice if it has changed and can actually show you the offending one now.
