- Each audit item that does not pass the SQL statement can correspond to a unique SQL baseline, that is, each SQL baseline has a unique corresponding SQL number and a failed audit item number. If there are multiple audit items that the SQL statement does not pass, Create multiple corresponding SQL baselines. After the server extracts the audit result, the result of the audit is a failed SQL statement, and after obtaining the SQL number and the failed audit item number, it can first find out whether there is a corresponding SQL baseline in the audit database according to the SQL number, and if so, further In the SQL baseline corresponding to the SQL number, look for the SQL baseline that matches the audit item number. If there is, you do not need to re-establish the SQL baseline, just modify the audit status of the matching SQL baseline to fail.
- step S508 the basic state of the SQL is marked as failing.
- step S510 an SQL baseline is established according to the SQL number and the audit item number that does not pass.
- the SQL baseline is established in the audit database according to the SQL number and the failed audit item number, and the audit status in the SQL baseline is marked as failing.
- Step S404 analyzing the SQL baseline to obtain SQL audit data, and displaying the SQL audit data.
- the server may extract the newly established one from the audit database every preset time or the status is re-marked to not pass the SQL baseline, and obtain the audit data of the SQL, for example, every hour, three hours, etc.
- SQL audit data can include the contents of the SQL statement, SQL number, database name, user name, audit item number that fails to pass the review, etc., and display through the terminal.
- the database administrator can rectify the SQL statement according to the displayed SQL audit data to make it conform to the audit project.
- the audit status of the SQL baseline can be modified according to the rectification result. If the audit item that fails the SQL statement review has been rectified, The audit status of the SQL baseline that matches the rectified audit item number can be marked as pass.
- a baseline report may be generated at intervals, such as generating a baseline daily report and a baseline monthly report.
- the baseline report records all newly generated SQL baselines for that period of time, and a SQL baseline for changing the audit status. The database administrator understands the changes in the SQL baseline in the audit database.

- Each audit item that does not pass the SQL statement can correspond to a unique SQL baseline, that is, each SQL baseline has a unique corresponding SQL number and a failed audit item number. If there are multiple audit items that the SQL statement does not pass, Create multiple corresponding SQL baselines. After extracting the audit result, the result of the audit is a failed SQL statement, and after obtaining the SQL number and the failed audit item number, you can first find out whether there is a corresponding SQL baseline in the audit database according to the SQL number, and if so, further In the SQL baseline corresponding to the SQL number, look for the SQL baseline that matches the audit item number. If there is no need to re-establish the SQL baseline, simply change the audit status of the matching SQL baseline to fail. If there is no SQL baseline matching the SQL number and the failed audit item number, the SQL baseline is established in the audit database according to the SQL number and the failed audit item number, and the audit status in the SQL baseline is marked as failing.
- the display module 670 is configured to analyze the SQL baseline to obtain SQL audit data and display the SQL audit data.
- the server may extract the newly established ones from the audit database at preset time or the status is re-marked to not pass the SQL baseline, and obtain the audit data of the SQL, for example, every hour, three hours, etc., SQL
- the audit data may include the contents of the SQL statement, the SQL number, the database name, the user name, the audit item number that the audit fails, and the like, and is displayed through the terminal.
- the database administrator can rectify the SQL statement according to the displayed SQL audit data to make it conform to the audit project. After the rectification is completed, the audit status of the SQL baseline can be modified according to the rectification result. If the audit item that fails the SQL statement review has been rectified, The audit status of the SQL baseline that matches the rectified audit item number can be marked as pass.
- a baseline report may be generated at intervals, such as generating a baseline daily report and a baseline monthly report.
- the baseline report records all newly generated SQL baselines for that period of time, and a SQL baseline for changing the audit status. The database administrator understands the changes in the SQL baseline in the audit database.
- the result of the centralized auditing of the audit result is a SQL statement that does not pass the SQL statement, which can facilitate the database administrator to rectify the SQL statement that the database fails to pass, effectively improve the efficiency of the SQL audit work, and help improve the database. Data processing performance.
- the various modules in the above SQL auditing device may be implemented in whole or in part by software, hardware or a combination thereof.
- the display module 670 can send SQL audit data to the terminal through the network interface on the server, so that the terminal displays the SQL audit data;
- the audit module 640 can follow the preset audit by the processor of the server.
- the audit item in the template, the analysis result and/or the basic information is reviewed, and the audit result is obtained, wherein the processor can be a central processing unit, a microprocessor, or the like.
- the above modules may be embedded in the hardware of the server or may be stored in the memory of the server in a software form, so that the processor can call the corresponding operations of the above modules.
- the storage device may be a magnetic disk, an optical disk, or a read-only storage memory (Read-Only) Memory, ROM), etc.
