Abstract It‘s very powerful for DB Query Analyzer in text file process. I’ll give you a sample to show its powerful fuction. Please make sure that column name coinciding with the data should be included in the first row in text file.
Key words DB Query Analyzer
1 Brief introduction of DB Query Analzyer
DB Query Analyzer is presented by Master Gen feng, Ma from Chinese Mainland. It has English version named ‘DB Query Analyzer’ and Simplified Chinese version named ‘万能数据库查询分析器（DB 查询分析器）’.
Master Gen feng Ma, the developer of DB Query Analyzer, hopes he can cooperate with some software company such as Sybase, Embarcadero, Microsoft and so on. He thinks it will be the better way that DB Query Analyzer is assembled in the develop tools according to such software company so that more and more database application software developer will benefit from its powerful function, friendly interface, easy operation and applicability to every production of RDBMS.
Achievement of DB Query Analyzer
In the New products & Tools reviews of programmer second issue of 2007, DB Query Analyzer had been strongly recommended.
Now 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 20 and it has been download more than 92,000 times.

Development of DB Query Analyzer
After four years research, design, development and about three months integrated test based on Oracle, Sybase, DB2, Informix, MS SQL Server, MYSQL, MS ACCESS, FoxPro, Paradox, SQLite which is a embedded database system, EXCEL, TEXT and CSV, DB Query Analyzer is distributed to the world In 2007. From then on, the continuous improvement of function or interface has been done.
From version 2.0，EXE Packer isn't be used to prevent DB Query Analyzer from being debugged. It will be never judged as virus foolishly.
From version 3.01, it becomes free.
In version 3.02,it allows users to define the restrict character among single quotation marks, double quotation marks and none. If you reset it in the configuration window, the query result will take effect right now. However, If you reset the separator between SQL, it will take effect in the new opened SQL edit window.
From version 4.01, a useful function is added. Users can save the result with too many records into file in high efficiency.
In version 5.01, another useful function is added. It shows all the state of the SQL statements in all windows by an icon according to the item in menu windows.
The latest version of DB Query Analyzer is 5.02. In 5.02BUG occurs when replacing key words in SQL edit have been solved.
Out of question, 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.
2 Preface
It‘s very powerful for DB Query Analyzer in text file process. I’ll give you a sample to show its powerful fuction. Please make sure that column name coinciding with the data should be included in the first row in text file.
I will show you an example.
OS : Windows 2000 Server
Files : .CSV/.TXT
Client tool : DB Query Analyzer 5.02.
3 Create ODBC Data Source according to .CSV/.TXT
First I create a ODBC Data Source ‘TXT_CSV_ODBC’according to .CSV/.TXT by DB Query Analyzer. Click menu item toolsàODBC Data Source Manager to run the windows ODBC Data Source Administrator form.This is shown in Figure 1 and Figure 2.
Figure 1 Create ODBC Data Source ‘TXT_CSV_ODBC’
Figure 2 Create ODBC Data Source ‘TXT_CSV_ODBC’
4 Execute SQL after connected to ‘TXT_CSV_ODBC’
Run DB Query Analyzer 5.02, then click ‘File’ menu to choose ‘Connect’ to open the logging window. Select ODBC Data Source ‘TXT_CSV_ODBC’.
Figure 3 log in ODBC Data Source ‘TXT_CSV_ODBC’
Figure 4 User Tables coincide with ‘TXT_CSV_ODBC’ in Object View
Figure 5 .CSV/.TXT file coincide with ‘TXT_CSV_ODBC’ in windows explorer
You can get the result after you execute SQL statement.
Figure 6 Get data from two tables according to two .csv file
Figure 7 Get the rows according to two table shown in tabsheet messages
Figure 8 Open a .csv file by notebook
Figure 9 Execute SQL including words left outer join
Figure 10 Error occurs Execute SQL including words full outer join
Figure 11 Get data from .txt file with more than 70 thousands records
