Database Connections


What is adodb connection ?

The ADO(ActiveX Data Objects) Connection object is used to create a connection to a data source. Through this connection, you can access and manipulate a database.
What is adodb recordset?
 The ADO Recordset object is used to hold a set of records from a database table.To be able to read database data, the data should be loaded into a recordset.
⇒QTP Scripts for connecting to MS Access:
Option Explicit
Dim con,rs
 
Set con=createobject("adodb.connection") 
Set rs=createobject("adodb.recordset")

con.open "Driver={Microsoft Access Driver (*.mdb)};Dbq=C:\mydatabase.mdb;Uid=Admin;Pwd=;"

rs.open "select * from emp",con

Do while not rs.eof
VbWindow("Form1").VbEdit("val1").Set rs.fields("v1")
VbWindow("Form1").VbEdit("val2").Set rs.fields("v2")
VbWindow("Form1").VbButton("ADD").Click
rs.movenext
Loop

'Release objects'Release objects
Set rs= nothing
Set con= nothing

Note: The database we are using here is MS Access.Before running this script create a table in MS Acess.In the above script I used table called "emp" and column 'names as "v1" and "v2". "d:testdata.mdb" is path of the table which we created. The main use of this script is to use testdata of table(which is in  ' database) in the application. In the above script we are passing values from database to Textboxes in Windows Application.

rs.open "select * from emp",con

Do while not rs.eof

VbWindow("Form1").VbEdit("val2").Set rs.fields("v2")
VbWindow("Form1").VbButton("ADD").Click
rs.movenext

Do while not rs.eof

VbWindow("Form1").VbEdit("val2").Set rs.fields("v2")
VbWindow("Form1").VbButton("ADD").Click

Loop

'Release objects

Do while not rs.eof
VbWindow("Form1").VbEdit("val1").Set rs.fields("v1")
VbWindow("Form1").VbEdit("val2").Set rs.fields("v2")
VbWindow("Form1").VbButton("ADD").Click
rs.movenext
Loop

'Release objects

⇒QTP Script for connecting to Excel:
Option Explicit
Dim con,rs

Set con=createobject("adodb.connection")
Set rs=createobject("adodb.recordset")

con.open "DRIVER={Microsoft Excel Driver (*.xls)};DBQ=C:\TestStatus.xls;Readonly=True"
rs.open "SELECT count(*) FROM [Status$] where Status = 'Failed' ",con

Msgbox rs(0)

'Release objects
Set rs= nothing

Option Explicit
Dim con,rs

Set con=createobject("adodb.connection")

' Open a session to the database
con.open"Driver={SYBASE SYSTEM 11};Srvr=myServerAddress;Uid=Uname;Pwd=Pwd;Database=myDataBase;"
rs.open "select * from emp",con

Do while not rs.eof

A Tutorial to Send Email using JMeter

Sending email is a mundane activity in any professional’s life. It’s a common medium for communication nowadays. Therefore performance testing of email server is not only important but necessary for an organization. JMeter can be helpful to perform load testing in such scenarios. In this tutorial, we will see how JMeter can be used to send email. We will use SMTP Sampler of JMeter to send an email. JavaMail API is needed to enable email functionality in JMeter. Download it from  here  and paste the jar in JMeter’s lib folder. Now, perform below steps to configure SMTP Sampler. Add a new Thread Group under Test Plan. Right click on Thread Group and select Add–>Sampler–>SMTP Sampler. We need to populate SMTP server’s details in this sampler. We will use GMail for sending an email. For this, enter these values in SMTP Sampler fields. Server: smtp.googlemail.com, Port: 587. Provide values in Email Address From and To fields of Mail Settings section to specify sender...

JMeter Exceeded Maximum Number of Redirects Error Solution

While running performance test, JMeter allows maximum 5 redirects by default. However, if your system demands more than 5 redirects, it may result in JMeter exceeded maximum number of redirects error. In this post, we have listed down steps to overcome this error. Actual error in JMeter: Response code: “Non HTTP response code: java.io.IOException” Response message: “Non HTTP response message: Exceeded maximum number of redirects: 5” This error is noticed because  JMeter  allows maximum 5 redirects by default and your system may be using more than 5 redirects. You need to increase this count to more than 5 in jmeter.properties file. Follow below steps to achieve this. Navigate to /bin directory of your JMeter installation. Locate jmeter.properties file and open it in any editor. Search for “httpsampler.max_redirects” property in opened file. Uncomment the above property by removing # before it. Change to value to more than 5 Eg. 20. Save the file and restart JMet...

Difference Between Redirect Automatically and Follow Redirects in JMeter

In this post, we will highlight important difference between Redirect Automatically and Follow Redirects options. These options are found in HTTP Request sampler of JMeter. Knowing the difference will help you decide your performance test strategy. When you check Redirect Automatically option, JMeter will not consider redirect as separate HTTP request. This in turn may result as lower response time in your overall performance test. Whereas Follow Redirect option will consider each redirection as separate requests. This may result in comparatively higher response time. This only has any effect if “Redirect Automatically” is not enabled. To see the difference between these two, record a sample script and run it by checking Redirect Automatically and Follow Redirects option. The second option will generate more requests in your result listener. As you can see from the above post, knowing the difference between Redirect Automatically and Follow Redirects option makes difference i...
