在 PLSQL 中,我们可以通过简单的数学运算将距离从公里转换为米和厘米。以下是实现此功能的代码:
CREATE OR REPLACE FUNCTION convert_distance_TO_meters(kms IN NUMBER) RETURN NUMBER IS
meters NUMBER;
BEGIN
meters:= kms* 1000;
RETURN meters;
END;
CREATE OR REPLACE FUNCTION convert_distance_TO_centimeters(kms IN NUMBER) RETURN NUMBER IS
centimeters NUMBER;
BEGIN
centimeters:= kms * 100000;
RETURN centimeters;
END;
-- 调用函数实现公里到米和厘米的转换:
DECLARE
kms NUMBER := 5;
meters NUMBER;
centimeters NUMBER;
BEGIN
meters := convert_distance_TO_meters(kms);
centimeters := convert_distance_TO_centimeters(kms);
DBMS_OUTPUT.PUT_LINE(kms || '公里= ' || meters || '米');
DBMS_OUTPUT.PUT_LINE(kms || '公里= ' || centimeters || '厘米');
END;
运行以上代码会输出以下结果:
5公里= 5000米
5公里= 500000厘米
