Implement SELECT LIKE and CHAR_LENGTH() in a single MySQL query
Let us first create a table −
mysql> create table DemoTable -> ( -> Name varchar(20) -> ); Query OK, 0 rows affected (0.49 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('Chris Brown');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values('Adam Smith');
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable values('John Smith');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values('Carol Smith');
Query OK, 1 row affected (0.13 sec)Display all records from the table using select statement −
mysql> select * from DemoTable;
This will produce the following output −
+-------------+ | Name | +-------------+ | Chris Brown | | Adam Smith | | John Smith | | Carol Smith | +-------------+ 4 rows in set (0.00 sec)
Following is the query to implement SELECT LIKE and CHAR_LENGTH −
mysql> select * from DemoTable -> where Name LIKE '%Smith%' -> and char_length(Name) < 11;
This will produce the following output −
+------------+ | Name | +------------+ | Adam Smith | | John Smith | +------------+ 2 rows in set (0.00 sec)
