equals method
Compare this expression to value using = in SQL coalesced to FALSE.
This is equivalent to COALESCE(this = value, FALSE) in SQL.
The .equals extension method requires that one of the two operators
are non-nullable. Because NULL = NULL evaluates to UNKNOWN in SQL,
which is surprising in a Dart context.
If you wish to compare two nullable expressions you can use:
- isNotDistinctFrom, to get
NULLequivalent toNULL, or, - equalsUnlessNull, to explicitely get the SQL
=semantics.
Implementation
Expr<bool> equals(Expr<String> value) =>
ExpressionEquals(this, value).orElseValue(false);
