Understanding onFetch

Jose

Question: Can I manually stop fetching data by returning false in onFetch?

More details: My understanding is that BIRT I could use onFetch to script whether there is more data to be fetch. I want to know if I am understanding right. For example I would like to stop fetching data base on a variable, something like:

initialize():
rowNum = 0;
maxRowNum = 5;//or maybe set it to a params

dataSet.onFetch():
rowNum++;

if ( rowNum < maxRowNum )
{
return false;
}
{
return true;
}

Hi Jose,

I have not done this before, so I don't know if that is the case or not. I'll look into it. If you go into your dataSet editor and look in the "Settings" section, you can set a max number of rows returned from the dataSource there.
