I have a multi-valued short ASCII text column in one of the tables in my ESE database, that holds the person's phone numbers.

I have the new set of values, and I'd like to wipe the old values completely, and only use the new values.

The JET_bitSetRevertToDefaultValue bit doesn't seem to work. While the MSDN documentation says "It causes the column to return the default column value on subsequent retrieve column operations. All existing column values are removed.", I found that it does nothing (no return value is returned).

Or, is there an easy way to find out how many values does the column contain (this could be zero, e.g. when I'm doing an insertion, not update)? If it was, I could just run a loop from 'nValues' to 1, erasing the value by setting it to the null while providing the itagSequence value, to achieve what I want.

I'm programming C#, and using the latest version of ManagedEsent library.

Thanks in advance!
