Accessing Dataset at runtime

cwfranklin

Hello,

I have been trying to figure out a way to see if my dataset has returned any results from the java code before the render task.

Here is the issue that I want to resolve:
Our reports are stored in the database along with the status (Processing, Success, Faliure, etc.). I want to be able to determine whether the dataset returned no records and set the status to "No Records". In another system we were able to check to see if the report byte array was null and if so set the status accordingly, but this report also has report parameters displayed so it will never be null. I'm trying to get the row count after the run task and before the render task in order to set the status to accordingly.

Is there a way to do this?

You just want to be able to find out if the dataSet has returned any values or not? If this is the case, you can initialize a variable in your initialize script to "false" or to 0, and then in your onFetch of the dataSet in question, you could either set the variable to "true" or increment the variable, depending on what you did in the initialize event. Then you'd know based on that whether the dataSet returned any data.

Hope this helps.
