Getting the first part from the Postcode in MySQL

To get the first part, use SUBSTRING(). Let us first create a table −

mysql> create table DemoTable858(PostCode varchar(100));
Query OK, 0 rows affected (0.56 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable858 values('US90 456');
Query OK, 1 row affected (0.20 sec)
mysql> insert into DemoTable858 values('UK1 EN789343');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable858 values('ENG78884 736454654');
Query OK, 1 row affected (0.12 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable858;

This will produce the following output −

+--------------------+
| PostCode           |
+--------------------+
| US90 456           |
| UK1 EN789343       |
| ENG78884 736454654 |
+--------------------+
3 rows in set (0.00 sec)

Following is the query to get the first part from Postcode −

mysql> select substring(PostCode, 1, locate (' ', PostCode) - 1) AS GetFirstPart from DemoTable858;

This will produce the following output −

+--------------+
| GetFirstPart |
+--------------+
| US90         |
| UK1          |
| ENG78884     |
+--------------+
3 rows in set (0.00 sec)
