我试图在SQL命令行中运行它这是我的计划：

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);

    unconplanets int;
    constellation varchar(25);

    constellation:='&inputconstellation';
    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;

prompt

我的问题是，即使我改变输入，我也会收到错误：

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

所以这就是我输入的内容而这，我试图输入，我认为问题是距离所以我决定改变＆＃39; 1＆＃39; 1至＆＃39; 1.6。你能帮我吗？

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)正在抛出错误。

这不能容纳4.572 要保留4.572，您必须将声明更改为数字（5,3）。这意味着该数字在该期间之前将具有2位数字，并且在该期间之后具有3位数字。

Answer 2

问题在于具有小数精度的NUMBER数据类型。

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

例如：要保持值34.34434，数据类型应为NUMBER(7,5)

谢谢：）
