我正在尝试在MySQL中创建一个函数:CREATE FUNCTION F_Dist3D (x1 decimal, y1 decimal) DETERMINISTICBEGIN SET dist = SQRT(x1 - y1);END;#1064 - You havean error in your SQL syntax;
check the manu
constexpr bool is_nonzero_decimal_digit(char const c) noexcept return c == '1' || c == '2' || c(char const c) noexcept return c == '0' || is_nonzero_decimal_digit(c);
我是mysql的新手,当我尝试了所有的东西,放上分号,重新输入所有东西时,我不知道哪里出了问题。下面是我想要实现的代码: CREATE PROCEDURE PriceChange(thisCodeFromBook CHAR(4), thisFormat BEGIN SET PRICE = thisGivenPrice
WHERE BOOK_CODE>
