People tell me things like I spent five hours last night trying to fix a bug in a program, as if that is supposed to impress me. Not so. If you can t fix it after an hour or so, you should go and do something else. It doesn t matter what that thing is; just don t think too hard about the problem while you do it. When you come back to the code, it s amazing how many times you can then fix the bug in an instant, as if the back of your brain has been working away on the problem, and suddenly up pops the answer for you.

Network broadcasts are used to send packets to all nodes on a classful network. For network broadcasts, the host ID bits are set to 1. For a nonclassful network, there is no network broadcast address, only a subnet broadcast address. Subnet broadcasts are used to send packets to all nodes on nonclassful networks. For subnet broadcasts, the host ID bits are set to 1. For a classful network, there is no subnet broadcast address, only a network broadcast address. Limited broadcasts are used to send packets to all nodes when the network ID is unknown. For a limited broadcast, all network ID and host ID bits are set to 1.

Because the OLE DB model has a rich, cursor-based update model, it is possible to use SQL Server to update remote data sources using regular UPDATE statements These plans look identical to the local plans discussed in this chapter, except that the top-level Update operation is speci c to the remote source Because the storage engine model in SQL Server is originally based on the OLE DB interfaces, the mechanisms for performing local and remote updates are actually very similar In the case when a whole update query can be remoted (because the property information for every operator determines that the remote source can support an UPDATE statement that is semantically equivalent to performing the operation locally through the exposed OLE DB interfaces), SQL Server can and will generate complete remote INSERT, UPDATE, and DELETE statements to be performed on the remote server.

You should examine any query that you think can be completely remoted to make sure that it actually can in some cases there may be a speci c grammar construct or intrinsic function that is not necessary in the query that blocks it from being completely remoted The Distributed Query feature was introduced in SQL Server 70, and there are some limitations with the feature that you should consider when designing scenarios that use it First, the feature relies on the remote providers to supply very detailed cardinality and statistical information to SQL Server so that it can use this knowledge to compare different query plans As most OLE DB providers do not provide much statistical information, this can limit the quality of query plans generated by the Query Optimizer In addition, OLE DB is not being actively extended by Microsoft, and therefore some providers are not actively maintained.
