我的问题是这样的即使我改变输入我得到这个错误:
DECLARE
*
ERROR at line 1:
ORA-06502: PL/SQL: numeric or value error: number precision too large
ORA-06512: at line 15
所以这是我输入 而这一点,我是想输入,我想这个问题是距离,所以我决定改变“1” “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
答
age number(3,5)
正在抛出错误。
这不能容纳4.572 要保持4.572,你必须将声明更改为数字(5,3)。这意味着该号码在该期间之前有两位数字,在该期间之后有三位数字。
答
问题与NUMBER
数据类型有十进制精度。
在NUMBER数据类型中,第一个数字表示小数点两侧的总数位数,第二个数字表示小数点后的位数。
如:保留的34.34434
值的数据类型应该是NUMBER(7,5)
谢谢:)
让从基础开始:http://www.oracle.com/technetwork/issue-archive/ 2011/11-nov/o61plsql-512011.html。我建议你使用'PLS_INTEGER'或'SIMPLE_INTEGER',而不是'int'(因为这不是plsql),或者只是普通的旧NUMBER而没有精确性。其次,当输入如下数字时:'distance:='&inputdistance';',您可以将它作为距离:=&inputdistance ;,因为它会隐式地将字符串转换为数字,以便插入它。从这一点开始,请参阅您可能遇到的下一个问题,但请记住,您得到的错误是由精度引起的。 – g00dy
