1 Introduction
Chinese local programmer Ma Genfeng ( CSDN interview with Ma Genfeng : Chinese local programmer who is a master of massive data processing and analysis ) launched a personal work ---- Universal Database Query Analyzer, Chinese version DB Query Analyzer, English version " DB Query Analyzer " . It has powerful functions, friendly operation interface, good operability, spanning various database platforms and even EXCEL and text files.
You can query ODBC data sources (including all databases, TXT/CSV files, EXCEL files) data through it. ②You can execute multiple DML statements or even stored procedures at the same time, and the results will be returned in the form, text box, and file you set; ③When exporting tens of millions of pieces of data from the database, the efficiency is no different from that of DBMS; ④Permit execution The recordsets returned by multiple SQL statements are saved in multiple files; ⑤Allows users to customize single, weekly, monthly "SQL execution plan"; ⑥Has a powerful SQL "execution plan" function, you only need to "tool" - Option "SQL execution plan connection automatic recovery" in the "Options" window is set to "checked" state, then even if the database server is down during the "SQL execution plan", as long as the database server is in the "SQL execution plan" moment. Process the startup status, then the "SQL execution plan" will be executed; ⑦ Allow users to customize the field separator and line terminator in the export file; ⑧ 6 . The 03 version is fully compatible with any Microsoft Windows operating system series, including Windows 10, Windows 8, Windows 7, Windows Vista, Windows 2003, Windows XP, Windows 2000, Windows NT, Windows ME, Windows 9X, and can be directly on the Windows operating system run without changing any operating system settings or configuration.
The DB Query Analyzer has been downloaded more than 120,000 times in Zhongguancun Online ( http://xiazai.zol.com.cn/detail/27/264455.shtml ) , ranking the top 10 in the database rankings .
In "Programmer" 2007 No. 2 "New Products & Tools Review" section, the editor "specially recommended" the release of "Universal Database Query Analyzer".
I also wrote 89 articles in Chinese and English about the technology of "Universal Database Query Analyzer", which were published in "Computer Programming Skills and Maintenance", "Software", "Computer Times", "Computer Programming Skills and Maintenance", Baidu On the library, CSDN resources, and my four blogs ( CSDN blog, Sina blog, Qzone and Sohu blog).
This article will take the Chinese version of DB Query Analyzer version 7.01 as an example, to introduce in detail the newly added recordsets returned by multiple executed SQL statements are saved to multiple files, and the user-defined fields in the export file when the execution result is saved to the file. Separator and line terminator.
2 Configuration options: save the execution results of multiple SQL statements to multiple files
DB Query Analyzer version 7.01 also adds the function of "save execution results to multiple files". When it is not selected, the result set returned by the executed SQL command set is all saved to a file specified by the user; if this option is selected , if multiple SQL command sets that return recordsets are executed, the result returned by the first SQL command is saved to the file specified by the user, and the others are saved to Result2, Result3 and other files, and the file extension is the same as that of the first SQL command. Statements save result files with the same extension. Once this option is changed, it will take effect immediately. It is valid for displaying the result in "text mode" and saving the result to a file.
Figure 1 Click "Tools -> Options" in the main menu to open the "Options" window, select Save execution results to multiple files
3 Set the field separator and line separator of the exported file
DB Query Analyzer version 7.01 adds the function of setting the field separator. When generating the result data, the user is allowed to select the field separator as Tab, comma, |%| or user-defined. Once this option is changed, it will take effect immediately. It is valid for displaying the result in "text mode" and saving the result to a file.
DB Query Analyzer version 7.01 also adds the function of setting line terminators, allowing users to choose line terminators as \r\n, \n, \r, etc. or define them by themselves. Once this option is changed, it will take effect immediately, but it is only valid for saving the result to a file.
Figure 2 Click "Tools -> Options" in the main menu, set the field separator to "|%|", set the line terminator to a semicolon, and select the option "Save execution results to multiple files"
4 Execute multiple SQL statements and save the results to multiple files
DB Query Analyzer version 7.01 adds the function of setting the field separator. When generating the result data, the user is allowed to select the field separator as Tab, comma, |%| or user-defined. Once this option is changed, it will take effect immediately. It is valid for displaying the result in "text mode" and saving the result to a file.
Figure 3 There are no files in the directory where you want to save multiple files
Figure 4 6 groups of SQL statements to be executed
Figure 5 Set the menu item "Query -> Display Results -> Save Results to File", then F5 executes the SQL statement, select the directory and enter the file name to be saved in the first statement tb_road_4402.txt
图6 6组SQL语句执行完成，结果保存到tb_road_4402.txt、result02.txt、…、result06.txt
图7 用Window 资源管理器来查看目录“保存执行结果到多个文件”，已经生成了6个文件
图8 用UltraEdit打开tb_road_4402.txt，可以看到字段分隔符为“|%|”，行分隔符为“;”
