Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In order to solve the above technical problem, an embodiment of the present invention provides a method for generating a database function interface. Fig. 1 shows a process flow diagram of a method for generating a database function interface according to an embodiment of the present invention. Referring to fig. 1, the process at least includes the following steps:

step S106: and establishing a calling relation between the generated functional interface and the built-in data of the database so that when any functional interface is called, the functional interface is utilized to execute corresponding functional operation on the built-in data of the database.
According to the method for generating the functional interface of the database, at least one functional operation capable of processing the data in the database is determined, the functional interface capable of executing the functional operation is generated in the database aiming at each functional operation, and a calling relation is established between the generated functional interface and the data in the database, so that when any functional interface is called, the functional interface is utilized to execute the corresponding functional operation on the data in the database. Therefore, the functional interface which is generated by the generation method and used for processing the data in the database is the functional interface generated in the database, does not depend on an external environment and/or an external tool, and is provided for the database. For example, the functional interface for processing the data built in the database may be a functional interface which stores procedures based on the database and is written by using SQL statements. When the database runs, functional operations such as management and the like can be executed on the database by using the functional interface generated in the example without any additional condition, and the problem that the built-in data of the database can be processed only by using an external environment and/or an external tool in the prior art can be solved. Therefore, the functional interface generated by the method for generating the functional interface of the database according to the embodiment of the invention executes the functional operation on the database, which can greatly reduce the dependency on the outside when processing the built-in data of the database, thereby effectively reducing the maintenance cost, avoiding the limitation of time and/or space on the operation such as the management of the database, and expanding the application range of the database. In addition, the built-in data of the database is directly processed by using the functional interface generated according to the tool and/or the environment of the database, the participation of the external environment and/or the external tool is replaced, the memory resource can be saved, and the adverse effect on the operation of the database caused by processing the built-in data of the database by using the external environment and/or the external tool is avoided.
It should be noted that the database in the embodiment of the present invention may be any database that can use its own tool and/or environment generation function interface to manage the content data, and the embodiment of the present invention is not limited to this. In practical operation, the MySQL database is recognized and used by more and more users with the advantages of small size, high speed, low total cost of ownership, open source code, and the fact that the SQL language is the most common standardized language for accessing the database.
The foregoing describes a method for generating a database function interface according to an embodiment of the present invention. After the database functional interface is generated, the generated functional interface can be used for processing the built-in data of the database. Therefore, based on the generation method of the database function interface provided by each embodiment, the embodiment of the present invention further provides a processing method of the built-in data of the database. Fig. 2 shows a process flow diagram of a processing method of database built-in data according to an embodiment of the present invention. Referring to fig. 2, the process at least includes the following steps:
step S202: receiving an operation instruction in the process of operating the database, wherein the operation instruction has a one-to-one correspondence relationship with the functional interface generated according to the method for generating the database functional interface;
step S204: calling a functional interface corresponding to the received operation instruction;
step S206: and executing corresponding functional operation on the built-in data of the database by using the functional interface.
According to the processing method of the built-in data of the database, disclosed by the embodiment of the invention, in the process of operating the database, the operating instruction which has one-to-one correspondence relationship with the functional interface generated by using the method is received, the corresponding functional interface is called, and the called functional interface is used for executing corresponding functional operation on the built-in data of the database. Therefore, according to the processing method of the built-in data of the database in the embodiment of the invention, the built-in data of the database can be processed by using the functional interface generated in the database, the problem that the built-in data of the database can be processed only by using an external environment and/or an external tool in the prior art is solved, and the efficiency of processing the built-in data of the database is improved.
When the method for generating the functional interface of the database is introduced, the database in the embodiment of the present invention may be any database that can generate the functional interface by using its own tool and/or environment to manage the content data, which is not limited in the embodiment of the present invention. Moreover, the database in the embodiment of the invention comprises a MySQL database. Now, the MySQL database is taken as an embodiment to introduce the processing method of the built-in data of the database, and the MySQL database is simply referred to as MySQL.
According to the above, in the process of running MySQL, a running instruction can be received. In order to ensure the security according to the received operation instruction and avoid the damage of the received malicious operation instruction to the MySQL built-in data, in this example, before the operation instruction is received, the MySQL is logged in by using the login identification information. And when the login is successful, calling a functional interface corresponding to the operation instruction when the operation instruction is received so as to process the MySQL built-in data. If the login fails and the current user may not have the processing authority on the MySQL built-in data, the MySQL built-in data is refused to be processed by calling a corresponding functional interface according to the received operation instruction, so that the security of the MySQL built-in data is ensured.
When the login is successful, if an operation instruction is received, the embodiment of the invention calls the functional interface corresponding to the received operation instruction, and executes corresponding functional operation on the MySQL built-in data by using the called functional interface. After the corresponding functional operation is executed on the MySQL built-in data by using the functional interface, in order to ensure that the operation result can be timely obtained so as to adjust the subsequent operation on the MySQL built-in data according to the operation result, the embodiment of the invention displays the operation result according to a preset mode. The preset mode used for displaying the operation result can be any mode capable of displaying the operation result. For example, the manner of displaying the operation result may include a scroll display manner, a pop-up window display manner, and a manner of displaying a part or all of the operation result.
In addition, the functional operation, which is executed on the MySQL built-in data by calling the functional interface corresponding to the received execution instruction in the embodiment of the present invention, may include any management operation and/or statistical operation and/or maintenance operation and/or detection operation, and the like, which are executed on the MySQL built-in data. For example, the functional operations performed on the MySQL built-in data may include batch close progress operations, slow statement grab operations, index usage monitoring operations, clean-up operations, statistical operations, query operations, and so on. Wherein, the statistic operation may further comprise an access amount statistic operation and/or a table information statistic operation. The query operations may further include an access volume status query operation, an index status query operation, a lock status query operation, an authorization information query operation, a Structured Query Language (SQL) usage frequency query operation, an input output consumption value query operation, and so on.
In order to explain the processing method of MySQL built-in data provided by the above embodiments more clearly and clearly, the embodiments are now provided to introduce the processing method of MySQL built-in data provided by the embodiments of the present invention.
Example one
In the MySQL operation process, an access quantity state value viewing instruction (one of operation instructions) is received, a dbastat function interface is called, a first com _ commit and a second com _ commit which are separated by preset time and a first com _ rollback and a second com _ rollback are obtained from an information _ schema.
For example, the first com _ commit and the second com _ commit at the interval time of 10 seconds are acquired as 80 and 90, respectively, the first com _ rollback and the second com _ rollback at the interval time of 10 seconds are acquired as 10 and 60, respectively, and after difference operation is performed, the first difference value is acquired as 10, and the second difference value is acquired as 50.
And adding the obtained first difference value and the second difference value, and keeping the obtained result in preset time to obtain the access volume state value. If the first difference is 10, the second difference is 50, and the predetermined time is 10 seconds as in the above example, the access volume status is 6 in units of each second.
After the access value state value is obtained, the cycle number of displaying the access value state value is determined according to the preset time, and the access value state value is displayed according to the determined cycle number. For example, the preset time is 10 seconds, and if the access amount status value is displayed once per second, the number of cycles is determined to be 10 times. In addition, since the access amount status value is a single value and is not usually compared with other status values, the access amount status value can be displayed in a manner of selecting a scroll presentation when the access amount status value is displayed.
Example two
In the process of running MySQL, if an index state viewing instruction (one of running instructions) is received, a dbaindenxno functional interface is called, library name information and table name information are obtained from information _ schema.
For example, using dbaindenxno to obtain the library name information and the table name information from the information _ schema. Then, using dbaindenxno to remove the index name information with empty index name information and the index name information with prime index name information from the performance _ schema _ table _ io _ criteria _ sum _ by _ index _ use, and determine the result (i.e. each index entry not used on the line) that COUNT _ STAR is 0.
After the index status query operation is completed, the determined each unused index entry is exposed, and when the number of unused index entries is too large, only a preset number of unused index entries may be displayed. For example, the number of currently unused index entries is 10000, and when the unused index entries are exposed, only 20 are displayed, so that the index is optimized in the subsequent operation.
EXAMPLE III
In the process of running MySQL, if a LOCK state query instruction (one of the running instructions) is received, a dblock functional interface is called, and an INNODB _ TRX table, an INNODB _ LOCK _ WAITS table and an INNODB _ LOCK table in the information _ schema library are obtained by using the dblock functional interface. And comparing the obtained INNODB _ TRX table, the INNODB _ LOCK _ WAITS table and the INNODB _ LOCK table to obtain locked thread information, finishing the LOCK state query operation and displaying the obtained locked thread information. When displaying the locked thread information, the obtained locked thread information may be displayed, including the locked thread identification information, the thread locking time information, and a Structured Query Language (SQL) that triggers thread locking.
The processing method of MySQL embedded data according to the embodiment of the present invention is further described above with three embodiments. It should be noted that, as can be seen from the foregoing, the functional operations performed on the MySQL built-in data in this example include any processing that can be performed on the MySQL built-in data, and are not limited to the functional operations provided in the above three embodiments. For example, the functional operations that can also be performed on MySQL built-in data in this example include:
(1) calling data in an information _ schema, processing list table according to the input field type by using a dbakell functional interface, and executing the operation of closing the corresponding connection thread;
(2) and calling data in the information _ schema, processing list table by using the dbaslow functional interface to obtain a preset number (for example, 100) of SQL with the longest execution time on the current line.
(3) Using a dbatable functional interface to call an information _ schema, schema and information _ schema, tables and calculate information such as distribution of the tables, size of indexes, number of rows of the tables and the like;
(4) using the dbaindex functional interface to call the information _ schema, static and information _ schema, tables of the specified library, and comparing to obtain the table index state, the table row number and other information of the specified library;
(5) calling the authorization information of the database by using a dbagarant functional interface, and fuzzy matching and listing the corresponding authorization information according to the provided user name, the network interconnection protocol field and the like;
(6) calling tables, statuses, columns and key _ column _ use in the information _ schema by using a dbaware functional interface so as to execute preheating operation on the database before each application is put into use;
(7) calculating a performance _ schema, events _ statuses _ summary _ by _ digest table by using a dbasqlmost functional interface to obtain a statement with the maximum execution times in the online statements from the starting time to the current time;
(8) calculating a performance _ schema, table _ io _ criteria _ summary _ by _ index _ use table by using a dbahottable functional interface to obtain table name information with the highest access frequency;
(9) calculating a performance _ schema, table _ io _ criteria _ summary _ by _ index _ use table by using a dbaiofile functional interface to obtain file name information of a file with highest input and output consumption;
(10) utilizing a dbacleanps functional interface to execute emptying operation on each statistical table under the performance _ schema;
(11) and performing joint calculation on tables such as events _ states _ summary _ by _ digest, table _ io _ ways _ summary _ by _ index _ use, events _ ways _ history and tables in information _ schema in the performance _ schema library by using a dbasqlanalyze functional interface, and obtaining the time consumption of each step in the execution process of the single SQL.
