The fact that identity columns refuse to accept data can be a serious issue if you re inserting existing data whose primary key is already referenced by secondary tables. In the Aesop s Fables sample database, for example, the primary keys are hard-coded into the insert/value statements in the populate scripts, much as the primary keys are already known during data conversions. The solution is to use the identity_insert database option. When set to on it temporarily turns off the identity column and permits the insertion of data into an identity column. This means that the insert has to explicitly provide the primary-key value. The identity_insert option may only be set on for one table at a time within a database. The following SQL batch uses the identity_insert when supplying the primary key:

x = V[2

The linear relation between cyv- and 1/ ,/aea is well known."i Figure 11.10a shows the measured dependence for avT versus 1/ /area. In order to test the hypothesis thai: depletion charge is the dominant factor in threshold matching, Table 11.7 compares the AVT coefficients as measured and as calculated using Eq. 11.14. The quantity Nxxd was derived in process simulation that was tuned with accurate C/V measurements. 14 '2 In the case of three out of the four coefficients the fit is good; the deviation of the 0.6-jim NMOST was caused in this experiment by annealing problems. The large PMOST coefficient of the 0.8-jim PMOSTs is caused by the compensation that occurs between the N- and PMOST threshold adjust and n-well implants. The total dopant quantity Nx = (Na + Nd) is

Version: Four bits identifying the IP version number. The version number is 6. Class: Eight bits used by originating nodes and/or forwarding routers to identify and distinguish between different packet classes or priorities as set by upper layer protocols. Originally known as the priority eld, this eld replaces the type-of-service eld in IPv4. Flow Label: Twenty bits used by a source host indicating any special handling requested for a ow, or sequence, of datagrams. Each datagram in the ow between an originating host and one or more destination hosts must carry the same ow label. Real-time voice, audio, or video communications are examples of applications involving ows that require non default handling. The ow label will allow routers to identify and process Voice-over-IP (VoIP) packets more easily. Payload Length: Sixteen bits describing the total length of the datagram. This eld is much like the total-length eld in IPv4, although the payload length eld does not include the IP header. As mentioned above, IPv6 supports jumbo payloads larger than the traditional 65,535 octets. At a minimum, all network links must support a Maximum Transmission Unit (MTU) of at least 1280 octets. The recommendation, however, is that network links be con gured to support an MTU of 1500 octets or greater in order to support encapsulation of Ethernet payloads without incurring fragmentation. The IPv6 payload length includes any IPv6 header extensions, TCP or UDP headers, and any layer 7 headers that might be associated with the datagram. Next Header: Eight bits identifying the header immediately following the IPv6 header. Examples (values) include TCP (6), UDP (17), fragment (44), and
