This can be achieved by using the expression “?Filecount”. The value of the “Filecount” variable can also be printed in the command window. The below mentioned picture represents the successful execution and the value of the variable. Now the value of the variable has been displayed when you place the cursor over the variable. Once the variable has been corrected (as “User”), the same line has been executed successfully. The exception has been caught by the VSTA and details are displayed in the dialog box as per the picture below. In the below mentioned picture, the line has been hit during the execution.Īs the variable collection has been misspelled, it is expected that the exception will be thrown. Hence I am expecting the script task to fail, while evaluating the value of the variable. To explain the failure scenario, I have purposely misspelled the variable as “user”, instead of “User”. So let’s have a look at a sample failure scenario. The main purpose of the debugging is to explore and understand the cause of the failure. The value of the variable can also be printed in the immediate window as well. Now the value of the variable can be evaluated by placing the cursor over the variable. The value of the variable will be derived and will be displayed in the message box. In the above mentioned picture, we are reading the value of the user variable “Filecount” and assign it to local variable “Filecount”. Now the breakpoint line will be highlighted and the execution will be paused. At run time, the visual studio for application (VSTA) will open the script task in read only mode. The breakpoints will be listed in the bottom of the dialog box with the line number and the name of the function. The “Set Breakpoints” dialog box shows the breakpoints in the script task. The below mentioned picture highlight the defined breakpoint in the script task. The defined breakpoints can be managed in the VSTA and it can be removed from the “Set Breakpoints” dialog box in SSDT designer. Once set, the debugging line will be identified using the red dot in the left margin. Break point can be set by placing the cursor on a line and pressing the function key F9. This will help us see the value of the variable at the time of execution. Setting a breakpoint will help us to stop the debugger during execution.

The below mentioned picture represents the code within the script task to use the Message Box.ĭuring the execution the SSIS will show a message box with a value as per the picture below. This is very primitive level debugging to know the details. This can be achieved by using the code below. By displaying a string or a variable, the developer will be able to debug. In this technique, we will be using the Message Box (Dialogue Box) to show the value of the variable or a string in the screen. The logging and “Try catch” methods are ideal to debug during the run time. The Message Box and Breakpoint options are suitable for design time debugging. There are four debugging methods are available. Using this sample package, we will be exploring the debugging techniques. The below mentioned image represents the sample package at high level. This script task accept one user variable (Filecount). To explain multiple debugging facilities, I have created a sample SSIS package with one script task. Hence we need to use other alternative techniques to understand the procedure during execution. In this case, you will not be able to use the SSDT to debug the package. Run time analysis is useful, once the package has been deployed and scheduled to run at a specific time. You will be using the SSDT to debug and investigate. This method is suitable while you are developing a package. These debugging techniques have been classified into two groups. In this blog post, I have consolidated a number of techniques to debug the script task. Though there are many advantages of using the script task, it is usually undermined by the developers because of the complexity to debug and fix the issues. Querying Active Directory service Interface (AD) from SSIS to extract the list of membership groups for a given user idįilter source data files based on a number of criteria (size of the file, date and contents of the file, etc.) Whereas the script component has been used in the data flow as a source, destination or a transformation.įollowing are few examples which describe the power of script task The script task is used in the control flow as a task. The script task is an ideal alternative solution to built-in tasks.īoth the Script Task and the Script component have the provision to extend the default functionality using C# or VB.Net. In these cases, we can achieve the functionality using C# or VB.net code in script task. In SQL Server Integration services (SSIS), it may not be possible to meet all the business requirements using built-in tasks.
