Public Members

name	description
Criteria(…)	Creates a new criteria with the given condition. This condition is usually a field name, but it can also be a pre-generated criteria text. (10 constructors)
static Bracket(…)	Creates a new criteria containing the field name in brackets.
Expression { get; }	Gets the criteria expression.
Field { get; }	Gets a reference to the `IField` object passed to the constructor.
override IsEmpty { get; }	Gets whether the criteria is empty.
override ToString(…)	Converts the criteria to its string representation while adding its parameters to the target query.
static readonly Empty	An empty criteria instance.
static readonly False	The false criteria instance (0 = 1).
static readonly True	The true criteria instance (1 = 1).
static EscapeLikeWildcards(…)	Escapes a literal value for use in a LIKE pattern with the given escape character. The escape character itself is escaped first, then %, _ and [. A ] outside a [...] class is literal on all supported dialects, so it is left as is. The result must be used with ESCAPE 'x' declared (see `LikeEscapeChar`), otherwise the escape character matches itself instead of escaping.
static Exists(…)	Creates a new EXISTS criteria. (3 methods)
