SummaryThis article describes in detail the "universal database Query Analyzer", the Chinese version of the "DB Query Analyzer", and the English version of the "DB Query Analyzer" 6.03 to facilitate the creation of DB2 functions. The process of creating a DB2 storage is the same as that of creating a DB2 database. You can follow these steps. This example also applies to database systems (such as ORACLE) Where SQL statements are separated by commas ).

Starting from version 6.01, the SQL "Execution Plan" function has been added to the Chinese and English versions of the universal database query analyzer. From version 6.02, you only need to set the option "SQL Execution Plan connection Automatic Recovery" in the "tool-à option" window to "selected" status, even if the database server goes down during the "SQL Execution Plan" period, as long as the database server processes the startup status at the time of the "SQL Execution Plan, the "SQL Execution Plan" will be executed.

The universal database query analyzer in both Chinese and English versions is fully compatible with any Microsoft Windows operating system series, including Windows 10, Windows 8, Windows 7, Vista, Windows XP, Windows 2000, Windows NT, Windows ME, and Windows 98. When running on a Windows operating system, you do not need to change any operating system settings.

1 Introduction

Ma genfeng, a local programmer in China (Interview with Ma genfeng in CSDN: A Chinese programmer who is a master of massive data processing and analysis) Released personal work ---- universal database Query Analyzer, Chinese Version DB Query Analyzer and English version DB Query Analyzer. It has powerful functions, friendly operation interface, good operability, spanning a variety of database platforms and even EXCEL and text files.

You can use itQuery ODBC data sources (including all databases, TXT/CSV files, and EXCEL files in the world. You can execute multiple DML statements and even the storage process at the same time, and the results will be returned in the table, text box, and file you set;When exporting tens of millions of data records from a database, the efficiency is no different from that of DBMS;With the powerful SQL "Execution Plan" function, you only need to set the option "SQL Execution Plan connection Automatic Recovery" in the "tool-à option" window to "selected" status, even if the database server goes down during the "SQL Execution Plan" period, as long as the database server processes the startup status at the time of the "SQL Execution Plan, the "SQL Execution Plan" will be executed;Version 6.03 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, and Windows 9X, which can be run directly on Windows OS, you do not need to change any settings or configurations of any operating system.

DB query analyzer is online in Zhongguancun (Http://xiazai.zol.com.cn/detail/27/264455.shtml) Downloads exceed 0.11 million times, ranking first 10 in the entire database category ranking.

 

In the "New Product & tool comments" section of "programmer" 2007, "Special Recommendation" was edited and the "universal database query analyzer" was released.

I also wrote about the related technologies of "universal database query analyzer ".77Article, published on "computer programming skills and maintenance", "software", "Computer Age", "computer programming skills and maintenance", Baidu Library, CSDN resources, and my blog (CSDN blog, Sina Blog, QQ space, and Sohu blog ).

This article will take the Chinese version DB query analyzer version 6.03 as an example to introduce in detail version 6.03 to easily and quickly create DB2 functions. The creation of DB2 storage process is the same as this, you can refer to the following steps. This example also applies to database systems (such as ORACLE) Where SQL statements are separated by commas ).

 

 

2 6.03 Chinese Version DB query analyzer as an Example

The following uses the Chinese version of the "universal database query analyzer" database query analyzer 6.03 as an example to access the DB2 database based on AIX.

Front-end Operating System: Windows 2000Server Operating System

Foreground program: DB query analyzer 6.03

Background Database: DB2

3 DB query analyzer create DB2 function examples conveniently and quickly


Figure 2 in the SQL Editor, enter the SQL statement used to create the DB2 Function

 

 


Figure 3 when the SQL separator is set to ';', an error occurs during function execution)

 



Figure 4 open the options window and set the SQL separator to '$'

 


Because only the newly opened window takes effect after the SQL separator settings are changed, a new window is created. on the lower right side of the status bar, you can see that the separator between SQL statements has changed to '$ ', as shown in:


Figure 5 install DB query analyzer 6.03 on Windows 8 (iii)

 

  



Figure 6 in the new window, paste the DB2 function creation statement in window 1

 




Figure 7 run the DB2 function creation statement. You can see that the statement has been successfully executed"

 



Figure 8 use two groups of test data to test the function execution and check whether the result is consistent with the expected value.




Figure 9 Execution of SQL statements containing user-defined functions

 




Figure 10 execution result data is successfully returned when an SQL statement containing a custom function is executed.
