Well I used CURSORSETPROP("Buffering", 5, "myCursor") and it still won't let me update it.

What I'm trying to do is insert data into dummy fields I built into a previous query. Like this:

SELECT table1.field1, table2.field2, 000000 AS dummy1, 000000 AS dummy2;
FROM table1, table2;
WHERE ..More SQL Stuff...
INTO CURSOR myCursor

In order to calculate the data I need I have to run a second SELECT, I'm working on a union solution but haven't been able to get it right yet, this is my work around.

After I run the second SELECT I just want to update/replace the data in the dummy values in myCursor. I keep getting "Can't update the cursor" with or without the CURSORSETPROP settings.

You will need to set several properties including Tables (the tables you will be updating), UpdatableFieldList (the fields that you want to be able to update), KeyFieldList (which fields are key values so the update can find the right record to update), UpdateType, and WhereType. There may be some other options you want to set, but I think this is the core set. Basically it sets the same properties that you would set visually when you design a View.
