甲骨文時間戳SYSDATE轉換錯誤

Question

提示錯誤是這樣的：將整個輸入字符串

declare 
    v_t timestamp; 
begin 
    v_t := to_timestamp(systimestamp,'DD/MM/YY')+interval '12-3' year to month; 
    DBMS_OUTPUT.PUT_LINE(v_t); 
end; 

Answer 1

SYSTIMESTAMP已經是一個時間戳，所以你不想打電話給to_timestamp做之前的日期格式的畫面結束。如果你想添加12年3個月到當前時間戳

SQL> ed 
Wrote file afiedt.buf 

    1 declare 
    2 v_t timestamp; 
    3 begin 
    4 v_t := systimestamp +interval '12-3' year to month; 
    5 DBMS_OUTPUT.PUT_LINE(v_t); 
    6* end;
