Many C++ programmers will be familiar with the tidal wave of recompilations that occur when a seemingly unrelated header file is changed. C++ file dependencies need to be managed otherwise compilation times will grow unchecked. Large build times can cripple the process of creating software and eventually kill a project.Suppose

There are two undocumented encryption functions. They are not supported by Microsoft, and I have had problems with some SQL Server service packs when using these functions. That being said, the two functions are pwdencrypt(
By default, SQL Server 7.0 installation sets up SQL Server to run in a case insensitive mode. For most applications this may work great, but there are certain situations were case sensitive searches are required. For instance, if a web site needs to have passwords that are case sensitive a
Certain applications require business logic to determine the last day of the month. This is the case for accounting applications that perform such tasks as invoice processing and customer billing.

When tuning SQL Server applications, a certain degree of hands-on experimenting must occur. Index options, table design, and locking options are items that can be modified to increase performance. When running a test, be sure to have SQL Server start from the same state each time. The cache (sometimes referred
Whenever a client application needs to send Transact-SQL to SQL Server, send it in the form of a stored procedure instead of a script or dynamic Transact-SQL. This not only reduces network traffic (only the EXECUTE or CALL is issued over the network), but it speeds up the Transact-SQL because
When a stored procedure is first executed (and it does not have the WITH RECOMPILE option), it is optimized and a query plan is compiled and cached in SQL Server’s buffer. If the same stored procedure is called again from the same connection, the server will use the cached query
