[odb-users] Creating BLOBs out of vector/array of doubles?

[Szumowski, Thomas]

I realize I can make BLOBs out of a vector or array of chars, but what about other data types?

I have a large array of doubles (10000+ elements) that I'd like to store in the database using ODB. The array does not need to be queried on, just associated as a single element in a table.

So ideally I'd like to BLOB the array (or vector) of doubles as a single entry of data.

However, it seems when I attempt this I run into odb-related errors. I attached the code as well.
