Specifies the bind size to use when exporting a table that contains null data in a memo column from Microsoft Access. Microsoft Access binds the parameter with a columnSize of 4294967295. The OpenAccess SDK Client attempts to allocate a buffer of this size, and typically fails due to lack of memory.

To configure the bind size and get around this application bug, set the parameter bind size for SQL_CHAR, SQL_VARCHAR, SQL_BINARY, SQL_VARBINARY values to a reasonable value.
