Comparison Operators (Entity SQL)

  • [アーティクル]

Comparison operators are defined for the following types: Byte, Int32, Int16, Int64, Double, Single, Decimal, String, DateTime, Date, Time, DateTimeOffset. Implicit type promotion occurs for the operands before the comparison operator is applied. Comparison operators always yield Boolean values. When at least one of the operands is null, the result is null.

Equality and inequality are defined for any object type that has identity, such as the Boolean type. Non-primitive objects with identity are considered equal if they share the same identity.

The following table lists the Entity SQL comparison operators.
