Abstract   The latest version of DB Query Analyzer is 6.02. In 6.02, if yous elected the option ‘SQL Schedule Reconnect’ in window configurations, theSchedule SQL scripts will be executed as long as the Database Server is in use,even though the Database Server had been down.

          As I said in the interview with ChineseSystem Development Net, if I have time what I want to do is to realize the reconnection to DBMS in SQL Schedule Function even DBMS has ever been down. Today, I am very glad to realize this function.

Key words   DB Query Analyzer

 

 

1   Brief introduction of DB Query Analzyer 

DB Query Analyzer is presented by Master Genfeng, Ma from Chinese Mainland. It has English version named ‘DB Query Analyzer’ and Simplified Chinese version named   .

DB Query Analyzer is one of the few excellent Client Tools in the world for its’powerful function, friendly interface, easy operation and applicability to every production of RDBMS.      

It lets you query ODBC data sources,author SQL scripts and queries, return query results to a grid or free-form text or a file,retrieve ODBC driver information, execute multiple SQL scripts or stored procedures simultaneously, save the result to files with high efficiency which is as quick as tools provided by database system. What is more, from 6.01, DB Query Analyzer provides SQL Execute Schedule function to execute SQL scripts in certain time. If you select the option ‘SQL Schedule Reconnect’ in window configurations,the Schedule SQL scripts will be executedas long as the Database Server is in use, even though the Database Server had been down. 

  

Achievement of DB Query Analyzer

Inthe New products & Tools reviews of programmer second issue of 2007, DB Query Analyzer had been strongly recommended.

Now the Simplified Chinese version of DB Query Analyzer is the top 50 database application software in the famous software website http://xiazai.zol.com.cn/download_order/sub_550.html. In most case it lies the top 10 and it has been download more than 100,000 times.

71 technical articles about DB Query Analyzer have been published or been publishing in computer journal, BAIDU Library, the CSDN resource or my four blog-website.

 

A kind remind

Because Windows 7 / Windows 8 / Windows 10 start to select ‘/’  as the default seperator character between short date. This will result in an error while running DB Query Analyzer,including English version ‘DB Query Analyzer’ and Simplified Chinese version .

I will solve this BUG in DB Query Analyzer 6.03. In order to use DB Query Analyzer properly,please set ‘-‘ as the default setting of short date in Windows 7.

 

 

2   6.02 version new characteristic

The latest version of DBQuery Analyzer is 6.02.

In 6.02, if you selected the option ‘SQLSchedule Reconnect’ in window configurations, the Schedule SQL scripts will beexecuted as long as the Database Server is in use, even though the Database Server had been down.

Secondly,all the options in window configurations will be saved to configuration file when they are changed.

Thirdly, when new window is created in which the connection to Database Sever which has been down, menu items will not be set to unusable, unlike all the former versions. 

Fourthly, some codes have been optimized.

OS : Windows XP

Database system : DB2

Client tool : DB Query Analyzer 6.02.
