ADO Database Delphi

Question:
How do I specify a DefaultExpression for a TField object?
Answer:
If you set up a field attribute set and associate that set with
a field in your table that will work. If you set the value in
the object inspector it will let you enter in a string but it
will not reflect the value at runtime. If you try to set the
TField.DefaultExpression property at runtime like this:
MyField.DefaultExpression := 'MyValue';
It will compile but you will not get a default value at runtime
when you create a new record in the table by, say, clicking on
the + on the DBNavigator. To get the default value to take at
runtime the code assignment needs to be:
MyField.DefaultExpression := '''MyValue''';
In the Object Inspector. You just need to put 'MyValue'. Use
single quotes in the Object Inspector.
