Clear multiple ranges of same field on data source

Posted on by Jason0810M

Hello,

I have a scenario where I have added multiple ranges (as OR) on a datasource field using a multi select lookup.

I have used a loop to get the selected values and used:
qbds.clearRange(fieldNum(table, field));

for (int i = 1; i<=conLen(conValues); i++)
{
qbds.addRange(fieldNum(table,
field)).value(queryValue(conPeek(conValues, i)));
}

The problem with the clear range is that it is only removing one occurence of the field range and it is keeping all the other previous ranges on the field.

Is there any way to clear all occurences of the field range?

Yes, it is possible. You could utilize the second parameter of clearRange() (_occurrence), but I think it's easier to simply call clearRange() with a single parameter repeatedly.

You can either use a for loop (rangeCount() tells you how many times you need to run it), you a while loop checking if there is any range remaining (by utilizing findRange()).

Thanks Martin.

The rangeCount would not be feasible to use for me as there are many ranges on several other fields.

I've tried the findRange with the while loop and it works perfectly fine.
