| Hi, I have a few questions regarding default values set up on sql tables.1.If a field e.g. FieldA has a default constraint set up with value of N set up and the table has lots of row then set up with N. If I where to change the constraint to the value X, would all the rows with N set up already change to X?2.Do default constraints only work on new rows(inserts) into a table. For example if I updated fieldB and fieldA was set up with Null, but the default constraint says to set fieldA to N, would fieldA become N on the table update for FieldB.Hope this is understandable.Thanks |

I would have a test with a simple testtable to answer this question - so can you.
