示例1:
TEST_F(ExpressionOperatorTests, NotEqualOperator_Expression_Constant_ReturnsCorrectPredicate)
{
Expression<TestExpressionEntity, std::int32_t> expr = ::MakeExpression(&TestExpressionEntity::SetterGetterGetter);
Predicate<TestExpressionEntity> setterGetterIsNotEqualToSix = expr != 6;
SqlPredicate predicate = setterGetterIsNotEqualToSix.GetSqlPredicate(_registry);
EXPECT_EQ(1, predicate.GetNumberOfParameters());
EXPECT_EQ("(TestTable.SetterGetter <> ?)", predicate.GetPredicate());
}示例2: OR
TEST_F(ExpressionOperatorTests, OrOperator_Exoression_Expression_ReturnsCorrectPredicate)
{
Expression<TestExpressionEntity, std::int32_t> expr = ::MakeExpression(&TestExpressionEntity::SetterGetterGetter);
Predicate<TestExpressionEntity> setterGetterIsEqualToSixAndOrSetterGetterIsNotEqualToFortyTwo = (expr == 6) || (expr != 42);
SqlPredicate predicate = setterGetterIsEqualToSixAndOrSetterGetterIsNotEqualToFortyTwo.GetSqlPredicate(_registry);
EXPECT_EQ(2, predicate.GetNumberOfParameters());
EXPECT_EQ("((TestTable.SetterGetter = ?) OR (TestTable.SetterGetter <> ?))", predicate.GetPredicate());
