使用trim()函数删除MySQL中的尾随零零。以下是语法-

select trim(yourColumnName)+0 As anyAliasName from yourTableName;

让我们首先创建一个表-

mysql> create table removeTrailingZero
   -> (
   -> Number DECIMAL(10,4)
   -> );

以下是使用insert命令在表中插入一些记录的查询-

mysql> insert into removeTrailingZero values(10.789);

mysql> insert into removeTrailingZero values(89.90);

mysql> insert into removeTrailingZero values(8999.70);

mysql> insert into removeTrailingZero values(0.40);

mysql> insert into removeTrailingZero values(0.0);

以下是使用select语句显示表中所有记录的查询-

mysql> select * from removeTrailingZero;

这将产生以下输出-

+-----------+
| Number    |
+-----------+
| 10.7890   |
| 89.9000   |
| 8999.7000 |
| 0.4000    |
| 0.0000    |
+-----------+
5 rows in set (0.00 sec)

以下是删除尾随零的查询-

mysql> select trim(Number)+0 As WithoutTrailingZero from removeTrailingZero;

这将产生以下输出-

+---------------------+
| WithoutTrailingZero |
+---------------------+
| 10.789              |
| 89.9                |
| 8999.7              |
| 0.4                 |
| 0                   |
+---------------------+
5 rows in set (0.00 sec
