Return only the first 15 characters from a column with string values in MySQL
To return only the first 15 characters from string values, use the MySQL SUBSTR() function.
Let us first create a table −
mysql> create table DemoTable ( Title varchar(100) ); Query OK, 0 rows affected (0.69 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('Introduction to MySQL');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values('Introduction to Java');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable values('C in Depth with data structure and algorithm');
Query OK, 1 row affected (0.15 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+----------------------------------------------+ | Title | +----------------------------------------------+ | Introduction to MySQL | | Introduction to Java | | C in Depth with data structure and algorithm | +----------------------------------------------+ 3 rows in set (0.00 sec)
Let us now implement the query to fetch only the first 15 characters −
mysql> select substr(Title,1,15) from DemoTable;
This will produce the following output −
+--------------------+ | substr(Title,1,15) | +--------------------+ | Introduction to | | Introduction to | | C in Depth with | +--------------------+ 3 rows in set (0.00 sec)
