我从数据库中获取一个值,我想将此值转换为 Mysql 中的单词。有人可以帮帮我。

例如: 123 - >这个值来自数据库,它以数字形式保存,我想从数据库中将此值检索为一百二十三

这样做的语法是什么?

查询是这样的:

从value_table中选择'value',日期为'10 -10-2012';

ans是 - > 123

我希望这个值显示为一百二十三。

请帮帮我。

我认为这可以帮助你...这只是一种方法:

DELIMITER $$
CREATE FUNCTION `number_to_string`(n INT) RETURNS varchar(100)
BEGIN
    -- This function returns the string representation of a number.
    -- It's just an example... I'll restrict it to hundreds, but
    -- it can be extended easily.
    -- The idea is: 
    --      For each digit you need a position,
    --      For each position, you assign a string
    declare ans varchar(100);
    declare dig1, dig2, dig3 int; -- (one variable per digit)

    set ans = '';

    set dig3 = floor(n / 100);
    set dig2 = floor(n / 10) - dig3*10;
    set dig1 = n - (dig3*100 + dig2*10);

    if dig3 > 0 then
        case
            when dig3=1 then set ans=concat(ans, 'one hundred');
            when dig3=2 then set ans=concat(ans, 'two hundred');
            when dig3=3 then set ans=concat(ans, 'three hundred');
            when dig3=4 then set ans=concat(ans, 'four hundred');
            when dig3=5 then set ans=concat(ans, 'five hundred');

            when dig3=7 then set ans=concat(ans, 'seven hundred');

            else set ans = ans;
        end case;
    end if;

    if dig2 = 1 then
        case
            when (dig2*10 + dig1) = 10 then set ans=concat(ans,' ten');
            when (dig2*10 + dig1) = 11 then set ans=concat(ans,' eleven');
            when (dig2*10 + dig1) = 12 then set ans=concat(ans,' twelve');
