You can remove trailing zeros using TRIM() function. The syntax is as follows.
SELECT TRIM(yourColumnName)+0 FROM yourTableName;
To understand the above syntax, let us create a table. The query to create a table is as follows −
mysql> create table removeTrailingZeroInDecimal -> ( -> Id int not null auto_increment, -> Amount decimal(5,2), -> PRIMARY KEY(Id) -> ); Query OK, 0 rows affected (1.01 sec)
Insert some records in the table using insert command. The query is as follows −
mysql> insert into removeTrailingZeroInDecimal(Amount) values(405.50); Query OK, 1 row affected (0.22 sec) mysql> insert into removeTrailingZeroInDecimal(Amount) values(23.05); Query OK, 1 row affected (0.17 sec) mysql> insert into removeTrailingZeroInDecimal(Amount) values(12.050); Query OK, 1 row affected (0.14 sec) mysql> insert into removeTrailingZeroInDecimal(Amount) values(125.23); Query OK, 1 row affected (0.14 sec) mysql> insert into removeTrailingZeroInDecimal(Amount) values(125.00); Query OK, 1 row affected (0.15 sec) mysql> insert into removeTrailingZeroInDecimal(Amount) values(126); Query OK, 1 row affected (0.14 sec)
Display all records from the table using select statement. The query is as follows −
mysql> select *from removeTrailingZeroInDecimal;
The following is the output.
+----+--------+ | Id | Amount | +----+--------+ | 1 | 405.50 | | 2 | 23.05 | | 3 | 12.05 | | 4 | 125.23 | | 5 | 125.00 | | 6 | 126.00 | +----+--------+ 6 rows in set (0.00 sec)
Here is the query to remove trailing zeros in decimal value. The query is as follows −
mysql> SELECT TRIM(Amount)+0 FROM removeTrailingZeroInDecimal;
The output displays the records without the trailing zeros.
+----------------+ | TRIM(Amount)+0 | +----------------+ | 405.5 | | 23.05 | | 12.05 | | 125.23 | | 125 | | 126 | +----------------+ 6 rows in set (0.00 sec)
