isValue method
Generates an IS
expression in SQL, comparing this expression with the
Dart value
.
This is the SQL method most closely resembling the Object.== operator in
Dart. When this expression and value
are both non-null, this is the same
as equals. Two NULL
values are considered equal as well.
Implementation
Expression<bool> isValue(D value) {
return isExp(variable(value));
}
