将聚合函数SUM()与REPLACE()一起使用。让我们首先创建一个表-
create table DemoTable857(Price varchar(100));
使用插入命令在表中插入一些记录-
insert into DemoTable857 values('50.60'); insert into DemoTable857 values('40.30.20'); insert into DemoTable857 values('10.20');
使用select语句显示表中的所有记录-
select *from DemoTable857;
这将产生以下输出-
+----------+ | Price | +----------+ | 50.60 | | 40.30.20 | | 10.20 | +----------+ 3 rows in set (0.00 sec)
以下是删除小数位和总和记录的查询-
select sum(replace(Price,'.','')) AS SumOfALl from DemoTable857;
这将产生以下输出-
+----------+ | SumOfALl | +----------+ | 409100 | +----------+ 1 row in set (0.03 sec)
