提问by user1876234
I would like to replace any 'dot' character in my query string, on SELECT
ing fields from database.
我想在SELECT
数据库中的 ing 字段上替换查询字符串中的任何“点”字符。
I'll need to modify lots of queries, I'm willing there's a function that will work to all columns on SELECT
. I mean something like this SELECT DOT_TO_COMMA(*) FROM...
我需要修改很多查询,我愿意有一个函数可以对SELECT
. 我的意思是这样的SELECT DOT_TO_COMMA(*) FROM...
Right now what I have:
现在我所拥有的:
SELECT price, lastprice FROM products
SELECT price, lastprice FROM products
OUTPUT: 22.10, 5.24
OUTPUT: 22.10, 5.24
EXPECTATION: 22,10, 5,25
EXPECTATION: 22,10, 5,25

please try this...
请试试这个...
this is working
这是工作
SELECT REPLACE(price,'.',',') AS price, REPLACE(lastprice,'.',',') AS lastprice FROM products
回答by rickslayer
In my case replace doesn't work well with negative numbers.
在我的情况下,替换对负数不起作用。
I use SELECT FORMAT (price,0)
.
Second parameter is de decimal numbers
我用SELECT FORMAT (price,0)
. 第二个参数是十进制数
