How to front pad zip code with “0” in MySQL?
To front pad zip code with 0, use LPAD() function in MySQL. The syntax is as follows −
SELECT LPAD(yourColumnName, columnWidth+1, '0') as anyVariableName from yourTableName;
To understand the above concept of LPAD() to add front pad zip code with 0, let us create a table. One of the columns of the table is Zip Code. The following is the query to create a table.
mysql> create table ZipCodePadWithZeroDemo
−> (
−> Name varchar(200),
−> YourZipCode int(6)
−> );
Query OK, 0 rows affected (0.44 sec)
Insert some records in the table. The query to insert records is as follows −
mysql> insert into ZipCodePadWithZeroDemo values('John',23455);
Query OK, 1 row affected (0.13 sec)
mysql> insert into ZipCodePadWithZeroDemo values('Carol',46523);
Query OK, 1 row affected (0.62 sec)
mysql> insert into ZipCodePadWithZeroDemo values('Johnson',12345);
Query OK, 1 row affected (0.11 sec)
mysql> insert into ZipCodePadWithZeroDemo values('David',34567);
Query OK, 1 row affected (0.18 sec)Display all records from the table. The query is as follows −
mysql> select *from ZipCodePadWithZeroDemo;
The following is the output −
+---------+-------------+
| Name | YourZipCode |
+---------+-------------+
| John | 23455 |
| Carol | 46523 |
| Johnson | 12345 |
| David | 34567 |
+---------+-------------+
4 rows in set (0.00 sec)
Implement the syntax which we discussed in the beginning to add front pad zip code with value 0. The query is as follows −
mysql> SELECT LPAD(YourZipCode, 6, '0') as UPDATEDZIPCODE from ZipCodePadWithZeroDemo;
We will also get the name here −
mysql> SELECT Name,LPAD(YourZipCode, 6, '0') as UPDATEDZIPCODE from ZipCodePadWithZeroDemo;
The following output displays the Name as well as the Zip Code −
+---------+----------------+
| Name | UPDATEDZIPCODE |
+---------+----------------+
| John | 023455 |
| Carol | 046523 |
| Johnson | 012345 |
| David | 034567 |
+---------+----------------+
4 rows in set (0.00 sec)
