Users would expect that deleting the contents of a field clear it - that may mean setting to null rather than "". At least, I've never found a use to make something NULL except for garbage collecting and storing "empty" dates in SQL Server (only because 12/31/1999 is not an elegant solution either.)

Updating views - strange errors 4. and I get error 1547.What am I missing? All I'm saying is that other languages get it wrong, from the viewpoint of a database, but VFP gets it right, so what's wrong with "VFP's support for null"? -- Peter AVG(integer) returns integer, when you may not want it to:SELECT ALL AVG(age), AVG(balance) FROM people You can fix it in VFP 9 with a CAST: SELECT AVG( CAST(age AS N(4,0))), AVG(balance)

Now we have nulls available, but (V)FP behaviour in a number of areas has not changed (for backward compatibility reasons) to make use of them as it 'should'. Change the WhereType property of the view." Something is fishy.

If they did not answer their age, and you stored that as 0, you would have an intresting time calculating statistics. P.S. А так я в том неправильном случае у себя не поставил флажок UpdateAble для KeyField. Потом уж "допёр". Делаю TableUpdate. Why is the data engine concerned with what the data is? VFP does know that this field has a NULL value replace x1.i1 with 0 ?
