As do I generate a virtual field boolean ?

[cybsistemas]

MyQuery.sql.text := 'select id, name, false as male from emp'

male is a virtual field, the version 5,20 LargeInt considers you and I cannot associate it to a TDBCheckBox

Thanks right now I realized

DBCheckBox1.ValueChecked := 1;
DBCheckBox1.ValueUnchecked := 0;
