想在 oracle dev6i 表格中获取当前年份

Question

DECLARE
    thisyear number(4,0);
BEGIN
    thisyear := year(getdate());
END;

Answer 1

您可以使用EXTRACT函数：

DECLARE
    thisyear number(4,0);
BEGIN
    thisyear := extract(year from sysdate);
END;

或者，您可以将 TO_CHAR 与格式字符串一起使用：

DECLARE
    thisyear number(4,0);
BEGIN
    thisyear := to_number(to_char(sysdate, 'YYYY'));
END;
