MySQL query to extract last word from a field?
To extract last word from a field, use in-built SUBSTRING_INDEX() function. The syntax is as follows −
SELECT SUBSTRING_INDEX(yourColumnName,’ ‘,-1) as anyVariableName from yourTableName;
To understand the above concept, let us create a table. The following is the query to create a table −
mysql> create table FirstWordDemo −> ( −> AllWords longtext −> ); Query OK, 0 rows affected (0.83 sec)
Now insert some words in the table using insert command. The query is as follows −
mysql> insert into FirstWordDemo values('This is the first MySQL Query');
Query OK, 1 row affected (0.11 sec)
mysql> insert into FirstWordDemo values('MySQL is a Relational Database');
Query OK, 1 row affected (0.17 sec)
mysql> insert into FirstWordDemo values('FirstWord is not correct');
Query OK, 1 row affected (0.21 sec)Now display all records from the table using select statement. The query is as follows −
mysql> select *from FirstWordDemo;
The following is the output −
+--------------------------------+ | AllWords | +--------------------------------+ | This is the first MySQL Query | | MySQL is a Relational Database | | FirstWord is not correct | +--------------------------------+ 3 rows in set (0.00 sec)
Here is the query to display the last word from a field. We discussed the same syntax in the beginning. The following is the query −
mysql> select SUBSTRING_INDEX(AllWords, ' ', -1) as MyFirstWordResult from FirstWordDemo;
The following is the output −
+-------------------+ | MyFirstWordResult | +-------------------+ | Query | | Database | | correct | +-------------------+ 3 rows in set (0.00 sec)
