Description of the invention () Field of the invention: The present invention is related to a database, especially a form with a table that stores query instructions. Library. BACKGROUND OF THE INVENTION: There are currently many database client applications that allow users to access databases. Structured Query Language (hereinafter referred to as SQL) is a special purpose data sublanguage, which can be defined and operated through a database in a relational database management system. Information. Although SQL cannot be used to write user applications that can access information in a database, such applications can be written using general-purpose application programming languages (such as C or COBOL) that include SQL. In other words, the SQL statement is embedded (e m b e d e d) in the program of the application language, and the program can compile to generate the user application of the database. SQL commands in the database user application can be used to store and retrieve data from the relational database. For example, a company's database might contain a form called "employees" (, 'employees') to store the name, social security number, residential address, company address, department, and salary of each employee in the company. For such a database, the SQL command: "insert into employees values ('Jones, Red', 111-22-333, ...") sets the relevant data of employee Fred Jones to "employees " Database form. Similarly, the SQL instruction: `` select name, serialNumber from page 3 This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) --------------- ----- Order --------- line (please read the notes on the back before filling out this page) Printed by the Employee Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 497051 A7 B7 V. Invention Description () employees ” , The names and serial numbers of all employees in the "employees" database form will be accessed. In operation, the user application program provides such embedded SQL commands to the underlying database management system to manipulate the data in the database. For example, to display the required information, the user application sends a SQL query to the database management system, then retrieves the generated information, formats the information, and displays the information to the user. When a database user application is written with embedded SQL instructions' and operations in the application are translated into the application's source code, this creates many disadvantages. First, when the SQL command used by the application changes, the source code of the database user application must also change. Because the SQL commands are stored in the source code of the application, all changes to the SQL commands must be changed in the source code and then recoded. Therefore, the modification of the S Q L instruction must be completed within the period of the source code change in the product cycle, or executed through the contractor of the user application. In addition, the SQL instructions in the source code must be applicable to the general public so that most users can use the application. Therefore, the Sql instruction dragon operation can be easily customized (C U S t om i z e d) or optimized for a specific user. "Secondly, 'Specialization can only be implemented through the application's contractor. Moreover, the performance tuning of the database is a continuous work on the client side, and is generally performed when the database application code is generated However, due to changes in the user's environment (eg, changes in workload, database size, or database usage), fine-tuning or changing SQL instructions must often time out.

Description of the invention () Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs for implementation. With the built-in SQL commands, the library code must be changed with each SQL command change. " ^ It will also require special service contracts with suppliers. In addition, even if the user signs a contract for the service, the supplier must be notified to perform any changes. Example _ For example, 'Every time a database administrator determines that a SQL command needs to be modified on the client side, the database manager must work with the vendor of the application to implement such a modification. . Because, at least right; μ, ㈤, 芏 / have two manpower must participate in the modification and testing of the application program, the cost of modifying the SQL instruction is increased. There is another disadvantage to high-usage database applications that must be run 24 hours a day, + weekly. Within & s is a command, every time the SQL command is modified, the user application must stop. However, it is impossible and unacceptable for such applications to be highly utilized or highly sought after. Furthermore, if the SQL code is included in the code of the database application and the SQL command changes need to time out, the current version of the database application itself must be recorded with the database form. That is, 'if the SQL command has been provided to a database with 10,000 records,' an application with a SQL command must also be backed up with the database. Similarly, the form name and data block can also be changed over time, so the application will not operate correctly unless the current version of the database application has such a database. In addition, if the application's code must change with each SQL instruction change, the application provider may inadvertently modify the SQL instruction originally (the 5th page of this paper applies to China) National Standard (CNS) A4 Specification (210 X 297 Public Love) -------------------- Order --------- Line (Please read the back first (Notes for filling out this page)

Defects of the invention description (or customs clearance); added to the code. Another disadvantage of using embedded SQL commands is that different database management systems (such as IBM dB / 2, Oracle, and Sybase) have different legal requirements for SQL commands. SQL instructions written for one platform may not work for the other. Similarly, SQL instructions can behave differently depending on the platform. Therefore, database user applications with embedded SQL commands may be restricted to specific database platforms, and different platforms must be written using different applications. Similarly, when SQL commands are embedded in the application's code, database applications are not general-purpose applications that can be used by various products. On the contrary, this application is a special-purpose product and cannot be used by other different products that need to access the database. Object and Summary of the Invention: In view of these disadvantages, the object of the present invention is to remove the above disadvantages and provide a database with a form capable of storing database query instructions, and the database query instructions can be used by database users. Used by the application. Create a database form in JL to store the query instructions. At run time, the database user application accesses the query instructions from the database form. Therefore, the query commands of the database user application can be easily changed without changing the code of the application or recoding the application. According to this, the 'database query command' (database quedes) contains all types of data definitions and operation commands (such as SQL commands), regardless of whether the information is to be obtained from the database.

When the query command is executed in the database server, the performance of the system is approximately 10 times higher than that of the Beibei library system using ^^^% soil. In addition, the system performance will not be degraded by issuing additional ^ query commands on the network to access the query command string.

Description of the invention () The SQL command issued to the database is derived from the SQL command stored in the query command form, so the SQL command can be changed at any time by changing the Sql command indicated by the identification code. In addition, the Internet service will automatically start using any new SQL commands placed in the query command form without degrading server performance. The extra time required to access the SQL instruction from the query instruction list can be ignored, because the query instruction form has only two columns and is generally less than 100 columns of data. For the purpose of illustration, the method for querying a database in a Sql environment according to an embodiment of the present invention may be described in detail with reference to the flowchart in FIG. 3. Initially, the database user application ClientApp, and the ID ID and other parameters of the SQL command called PARMS, can be called via the command: "(: with 1 ^ eight? (10 = 1,? Eight 113 =` `3 ( ^ 1 ^ 〇11 ")" (step 320). The user application issues a query command: ', select SQL from SQLTBL where ID =; T to the database management system to access the SQL command that matches the id (The first two columns of the SQL command form SQLTBL are shown in Table 1 below.) Next, the database management system responds to the required SQL command: 丨 'select name, serialN umber from employee where workLocation =? For read only " To the user application (step S24). Then, the user application replaces all blank spaces (such as "?") In the response SQL command with the received parameter PARMS (step S26), and then sends The completed SQL instructions are sent to the database management system: '' select name, serialNumber from employee where page 11 This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) --- --I -------------- Order --------- I (Please read the precautions on the back before filling out this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 497051 A7 B7 V. Description of the invention () workLoaction = 丨 'Boca Raton ,, for read only ,, (step Xian 蚨 S 2 8) and then' Database management system responds to the result of the query instruction issued, (that is, the name of the match And serial number) to the user application (step S30), the user application responds, or displays the result to the user for further processing (step S32). Table 1: SQL Command Form (SQLTBL) ID SQL command, 1 select name, serialNumber from employee where workLocation =? For read only 2 insert into employee (name, serialNumber) v ”As mentioned earlier, the present invention uses a database form to store the database user application used Database query instructions. Database user programs access query instructions in database forms during run time. Because #material library query instructions (such as SQL commands) can be used in database forms Save And therefore does not change the source code and shall be re-coded to make changes to the query command user application. Therefore, the database query command can be updated by the database manager in the database form without the assistance of the application vendor. In addition, using the database command form, the database query command can be customized and optimized on the client side to provide the best functions and the most efficient performance. When the database used by the user application is queried and the instructions are stored in the database form, the database performance fine-tuning procedure due to changes in the user's environment Page 12 This paper size applies Chinese National Standard (CNS) A4 specification (210 X 297 Mm) --------------- I ---- ^ --------- (Please read the notes on the back before filling this page) 丄 A7 B7 Economy Printed by the Consumer Cooperatives of the Ministry of Intellectual Property Bureau 5. Invention description (also simplified. In particular, the military and public information instructions can be changed at any time without the assistance of the application provider. The instructions in a database form also make the volume owed '4 can be operated by one person (such as the data manager), so the cost of modifying the Attachment is also reduced. Similarly, the changes to the database query instructions are not Must be changed to the original seven yards, so there will be no chance of accidentally causing problems to the application code. Because the change of the private order does not need to change the original code or re-encoding ', the query refers to A may 2 7 To effectively update each other and not Make the application private. This is more conducive to using the old application 1 which is more popular or urgent. Also, because the database query command is stored in the database form, the user can automatically query the command. It is stored with the database information, so the database check dog command is saved in synchronization with the database information, and because the application of the test king style itself does not need to be stored, the procedure for storing data is simplified. Database query instructions The form stored in the database also allows the query instructions to be fine-tuned, so that the application can operate normally and efficiently with the specific database platform used by the customer. Similarly, the application can be written as a general-purpose application . Therefore, the application program can be used as a database interface layer to communicate with different database platforms and other products that need to access the database. In short, the present invention proposes a flexible, which can be adjusted according to the needs of special users. Database user application. The database system of the present invention can be implemented in hardware, software, or a combination of both. For example, 'this At least part of the system can be stored in computer-accessible media (such as magnetic disks, optical disks, or non-volatile memory).
