Let us first create a table −
mysql> create table DemoTable623 (FirstName varchar(100),LastName varchar(100),Age int); Query OK, 0 rows affected (0.76 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable623 values('John','Smith',23); Query OK, 1 row affected (0.66 sec) mysql> insert into DemoTable623 values('Adam','smith',23); Query OK, 1 row affected (0.26 sec) mysql> insert into DemoTable623 values('Chris','Brown',24); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable623 values('Robert','brown',21); Query OK, 1 row affected (0.22 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable623;
This will produce the following output −
+-----------+----------+------+ | FirstName | LastName | Age | +-----------+----------+------+ | John | Smith | 23 | | Adam | smith | 23 | | Chris | Brown | 24 | | Robert | brown | 21 | +-----------+----------+------+ 4 rows in set (0.00 sec)
Here is the query to select statement using MySQL −
mysql> select FirstName from DemoTable623 where lower(LastName) ='smith';
This will produce the following output −
+-----------+ | FirstName | +-----------+ | John | | Adam | +-----------+ 2 rows in set (0.00 sec)
