OLEDB Parameter Question

[bob]

Hi,
I have a dataset that I want to use to insert records into an empty
Access database table.

The table does not have any indexes or required fields.
It is just a dumping ground enroute to an Excel spreadsheet.

The dataadapter update command fails with
"Parameter ?_6 has no default value"

It appears to be due to one or more fields having a null value or
empty string?

If I reduce the insert statement to a subset of the fields it works.

Given that the target table has no required fields what could be
causing this?
Is there a way around it?

Thanks
Bob

Bob,

The reason this is occuring is that you are not defining fields in your
insert query that need to be populated. If the field does not have a
default constraint, then you MUST insert some sort of value for it in your
insert statement.

It has nothing to do with a null value or an empty string.
