equals method

Expr<bool> equals(Expr<bool> other)

Compare this expression to other using = in SQL coalesced to FALSE.

This is equivalent to COALESCE(this = other, 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 NULL equivalent to NULL, or,
• equalsUnlessNull, to explicitely get the SQL = semantics.

Implementation

Expr<bool> equals(Expr<bool> other) =>
    ExpressionEquals(this, other).orElseValue(false);
