我試圖在SQL命令 此行運行,這是我的計劃:甲骨文 - ORA-06502:PL/SQL:數字或值錯誤:數字精度太大

我的問題是這樣的即使我改變輸入我得到這個錯誤:

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

所以這是我輸入 而這一點,我是想輸入,我想這個問題是距離,所以我決定改變「1」 「1.6。 你能幫我嗎?

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

讓從基礎開始:http://www.oracle.com/technetwork/issue-archive/ 2011/11-nov/o61plsql-512011.html。我建議你使用'PLS_INTEGER'或'SIMPLE_INTEGER',而不是'int'(因爲這不是plsql),或者只是普通的舊NUMBER而沒有精確性。其次,當輸入如下數字時:'distance:='&inputdistance';',您可以將它作爲距離:=&inputdistance ;,因爲它會隱式地將字符串轉換爲數字,以便插入它。從這一點開始,請參閱您可能遇到的下一個問題,但請記住,您得到的錯誤是由精度引起的。 – g00dy

age number(3,5)正在拋出錯誤。

這不能容納4.572 要保持4.572,你必須將聲明更改爲數字(5,3)。這意味着該號碼在該期間之前有兩位數字,在該期間之後有三位數字。

問題與NUMBER數據類型有十進制精度。

在NUMBER數據類型中,第一個數字表示小數點兩側的總數位數,第二個數字表示小數點後的位數。

如:保留的34.34434值的數據類型應該是NUMBER(7,5)

謝謝:)
