mysql select int as currency or convert int to currency format?
提问by gregjor
Is there a way to convert an int while selecting to an currency format. I can concat the '$' symbol but how do you place the ,'s in? Like turning int =1000 into $1,000?
有没有办法在选择货币格式时转换 int。我可以连接 '$' 符号，但你如何放置 ,'s ？比如把 int =1000 变成 1000 美元？
Or there is one function that can do it all? Is there a string replacement?
或者有一个功能可以做到这一切？有字符串替换吗？
