Remote views and SPT (SQL pass through) are two built-in solutions for developing client/server programs, and if you use VFP more deeply, the contents of these two parts must be mastered.Because the content is more, the article divides into several articles several times to send out. But personally, the remote view and SPT is indivisible, although the SPT applica

VFP because it is simple and easy to learn, can quickly set up application software by the vast number of programmers love, but its database system is not safe also makes the majority of users very headache. With the application of MS SQL Server database system, its powerful security can be widely praised. In the long-term programming practice, I found that the use of VFP SQL pass-through (SPT) technology combined with MS SQL Server database system, c

in 10g, Oracle launched its own SQL optimization aids : SQL Optimizer (SQL Tuning Advisor :STA) , it is the new Dbms_sqltune package. Use the STA to make sure that the optimizer is in CBO mode. but I think that using this tool is only suitable for people who don't understand SQL at all, and don't think that tools can solve problems. SQL is ultimately an expression of a business, how the tool might understand the business. SQL

Not every program needs optimization. If the performance of a program is the same as expected, you don't have to put extra effort into improving its performance. However, after the program debugging is completed, it is difficult to immediately meet its performance requirements, so we have to tune the job. Regardless of the programming
