These days everyone is so concerned about mobility whatever they can do on a computer, they want on their mobile phone as well.īusiness Intelligence is not an exception in this subject we don’t want to open our laptops everywhere just to make a small analysis. Over a short period of time all this has changed and our phone has become a medium for everything, your email, organizer, web, music, movies, podcasts, weather, dining and travel as well. Remember those times where phone used to be just a phone, all you can do is talk and carrying it around was a bit of task for us back then.

References : Qlikview Reference Manual v11 This variable will contain a concatenated list of all script errors that have occurred during the last script execution. This variable is always reset to 0 at the start of script execution. Returns the total number of statements that have caused errors during the current script execution.

Most importantly this variable will contain the error message returned by ODBC and OLE DB drivers for error codes 3 and 4. Returns a more detailed error description for some of the error codes above. Error codes are dual values with a numeric and a text component. If an error occurs it will be set to an internal QlikView error code. This variable will be reset to 0 after each successfully executed script statement.

Returns the error code of the last executed script statement. By setting ErrorMode =2 QlikView will trigger an “Execution of script failed…” error message immediately on failure, without prompting the user for action beforehand. By setting ErrorMode =0 QlikView will simply ignore the failure and continue script execution at the next script statement. By default (ErrorMode=1) the script execution will halt and the user will be prompted for action (non-batch mode). This variable determines what action is to be taken by QlikView when an error is encountered during script execution. I will quote error handling section mentioned in reference manual for your convenience here. Refer to Qlikview 11 reference manual for more detailed execution of these. If any other error than mentioned occurs in the script, it will exit from the load. It will only become 1 after finishing first statement execution or finishing the script ) which means if QVD exists then take data from Stage 2 QVD and append new data from Stage 1 QVD and store the same into that Stage 2 QVD which would replace existing QVD. So, IF ScriptError=8 or ScriptError=10, here ScriptError=8 is “File not Found” and ScriptError=10 is “Table Not Found”, So if either of these errors has occurred then create a Stage 2 QVD.ĮLSEIF ScriptError=0 ( I have used 0 as No Error, as when no errors are there ScriptError will stay 0. Next as our requirement is to find whether Stage 2 QVD exists or not? for this we will write a simple IF ELSE statement.
Careful, now though, you wouldn’t be able to see any errors in your application from this moment on. This is manual override for errors in Qlikview. So, now how would I handle that error, if that Stage 2 QVD is not there? Don’t freak out! Qlikview has it covered for us. Oh, it’s already there? Then go take data from it and add new set of data from Stage 1 QVD, to it.
So, first I will check whether Stage 2 QVD exists? If not, create it with first set of data. So, I don’t need to use any unique identifiers for this type of incremental load, just concatenate new data with a new date-stamp and store it away. My program is simple, I need to do an incremental load on a QVD (Let’s call it Stage 2 QVD), which stores snapshots of an existing data (Stage 1 QVD). So I thought I would give head start to those who would be trying to do their own error handling in Qlikview like me. To my luck, Qlikview did mention about it in their manual, not very detailed though. But, then there came a problem-”How would I do an increment load on a QVD, when it doesn’t exist in the first place? “ (Wait, it will be confusing, if you don’t know about incremental load, check it here, ) then I thought, if at all I could trap those errors and use them for my convenience, I’d be able to do this and there began my search for error handling in Qlikview.
Recently, one of our customers came up with this requirement: Create a QVD with an incremental load.
