要测试POWER函数的准确性,您可以使用以下步骤:
CREATE TABLE power_test (
base_number NUMBER,
exponent_number NUMBER
);
INSERT INTO power_test (base_number, exponent_number) VALUES (2, 3);
INSERT INTO power_test (base_number, exponent_number) VALUES (3, 2);
SELECT base_number, exponent_number, POWER(base_number, exponent_number) AS result,
CASE
WHEN POWER(base_number, exponent_number) = base_number ** exponent_number THEN 'Pass'
ELSE 'Fail'
END AS test_result
FROM power_test;
通过这些步骤,您可以测试POWER函数在Oracle中的准确性。您还可以根据需要添加更多的测试数据和情况来进行测试。
