Advanced: Requires expert coding, interoperability, and multiuser skills.

The ORACLE ODBC driver specification states:

  The limit in ORACLE 7 for long values (CHAR and BINARY) is 2 GB. The limit in ORACLE 6 is 64K. The limit imposed by OCI is 32K, so  this becomes the practical limit for long values of any kind.

Because the current ORACLE ODBC driver (version 6.0) uses OCI, the limit for any long value, such as a binary large object (BLOB), is 32K.

You will encounter this ORACLE ODBC driver limitation whenever you try to save graphical information, such as a bitmap, to an attached ORACLE database using Microsoft Access.

ORACLE is manufactured by Oracle Corporation, a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding this product's performance or reliability.
