Describes a (W)(VAR)CHAR(n) as a WLONGVARCHAR or LONGVARCHAR when n is larger than a specified value. The corresponding connection property, DescribeVarcharAsLongvarchar, sets the size n. This workaround is typically used in Oracle Heterogeneous Services, which does not support VARCHAR longer than 4096.
