Abstract: At present,The nearly all applications procedure all needs to have to do with the
database. May very easily obtain the data through the inquiry database
which wants. But,Unsatisfactory Italy is:Certain inquiry time are long,The speed of response is slow. Investigates its reason,One is the hardware equipment (for example CPU, floppy disk) the
access speed cannot follow,The memory capacity insufficiently is big,This need computer manufacturer endeavor;On the other hand has not carried on the inquiry optimization. A
mature management information system essential establishment above a
good database foundation,Because the user sets the very high request to the database inquiry
efficiency,Therefore must carry on the optimization to the database inquiryThrough introduction related database inquiry optimization
technology,Elaborates the SQL optimization inquiry realization method
specifically from several aspects. Key word: Relational operation; Inquiry optimization; SQL sentence; Optimized technology; Database;

Abstract: At present, database is concerned by almost very application. Requested data can easily acquired vis searching the database. However long searching and responsing time are always problems. Basicly, it is due to hardware limitations such as CPU speed, memory capacity, etc. which needs our manufacturer to work harder. And, also, it is because the search method is not optimized. A robust information system must be build on the basis of well structured database. The high requirements of efficiency from users need the searh algorithm to be optimized. The optimization of SQL algorithm will be discussed in several aspects, via the discussion of database search optimization.
Keywords: Key operation, Optimized search(query), SQL, Optimized technique, database

Now, almost all of the applied procedure all want to make deal with with database.Passing to search databasing can very and easily acquire the desirable data.But, dissatisfactory is: time of some searches is long, and respond to the speed slow.Investigate access speed that its reason, on is a hardware equipments( such as CPU, 磁 dish)ing can not keep up with, inside 存 the capacity is not enough and big, this demand the effort of the calculator manufactory; on the other hand did not proceeds search 优 of 化 .A mature of management information the system is essential to establish in a good database foundation on, because the customer search database the efficiency bring up the very high request, for this reason proceeds to the database's search 优化 . pass the introduction relevant database search 优化 technique, come to concrete 阐述 SQL 优 from a few aspects what化 search realizes method.

Current, almost all of the applied procedure all wants to make deal with with database.Passing to search database can acquire the desirable data very easily.But, dissatisfactory is: some searches time is long, responding to the speed slow.Investigate its reason, an is effort that hardware equipments( such as CPU, the dish of 磁 ) of the access speed cans not keep up with, the inside saves the capacity not enough big, this need the calculator manufactory; on the other hand is to did not proceed the search the excellent turning.A mature management information system is essential to establish in a good database foundation on, put forward the very high request to the search efficiency of the database because of the customer, therefore must proceed the excellent turning to the search of the database.Pass the relevant database in introduction search the excellent turning the technique, expatiate the SQL in a specific way from a few aspects the excellent turning search of realize method.
