Question

我正在尝试运行在 SQL 命令行中执行此操作这是我的程序：

set verify off;
set serveroutput on;

DECLARE
    starname varchar2(20);
    distance number(10,2);
    spectral varchar2(10);
    mass number(2,4);
    temp int;
    age number(3,5);

    INSERT INTO eonmultiplanetarysystem (ID, STAR_NAME, DISTANCE_LY, SPECTRAL_TYPE, MASS, TEMPERATURE_K, AGE, CONFIRMED_PLANETS, UNCONFIRMED_PLANETS, CONSTELLATION) VALUES (eonmultiplanetarysystem_seq.nextval, starname, distance, spectral, mass, temp, age, conplanets, unconplanets, constellation);
    commit;
    dbms_output.put_line(chr(20)||'Successfully Added!');
END;

我的问题是，即使我更改了我的输入，我仍然收到该错误：

DECLARE
*
ERROR at line 1:
ORA-06502: PL/SQL: numeric or value error: number precision too large
ORA-06512: at line 15

这是我输入的而这个，我试图输入，我认为问题是距离，所以我决定将“1”更改为“1.6”。你能帮帮我吗？

Enter the name of the star: Sun
Enter the light year distance: 1.6
Enter the spectral type: G2V
Enter the mass: 1
Enter the temperature(kelvin): 5778
Enter the age (Giga Year): 4.572
Enter the confirmed planets: 8
Enter the unconfirmed planets: 1
Enter the name of the constellation: None

Answer 1

age number(3,5) 抛出错误。

这不能容纳 4.572 要持有 4.572，您必须将声明更改为 number(5,3)。这意味着该数字将在句点之前有 2 位数字，在句点之后有 3 位数字。

Answer 2

问题出在具有小数精度的 NUMBER 数据类型上。

在NUMBER数据类型中，第一个Number表示小数点两边的总位数，第二个表示小数点后的位数。

例如：要保存 34.34434 的值，数据类型应为 NUMBER(7,5)

谢谢:)
