Store huge array into Access database

[PN]

I'm trying to store a huge array (600K+ elements) into Access database. Does
anyone know how? I tried to assigned each array element into each
field but Access 2000 had a limit of 255 fields. I saved to a binary file
but the program crashed with overflow error when it reached 8192th array
element (element type is Single so 8192th is 8192 * 4 = 32,768 bytes which
is the max. limit of record length). Any help would be appreciated.

Create a table with a Long Integer field (call it MyIndex) and another field
of the same type as the array (call it MyValue).

Store each array element as a separate row: the element number as the Long
Integer field, and its value as the other field.

For lngLoop = LBound(MyArray) to UBound(MyArray)
rsMyRecordset.AddNew
rsMyRecordset!MyIndex = lngLoop
rsMyRecordset!MyValue = MyArray(lngLoop)
rsMyRecordset.Update
Next lngLoop

Thanks Doug.
By the way, do you know how many records can an Access2K hold? If I have 1
million records, should I consider other databases such as Oracle or MSSQL
?

There isn't a fixed number. A single MDB can be as large as 2 GB, but you
can link together multiple MDB files if you have to.

I've worked with database in excess of a million records.
