MySQL database field type for search query?
Following is the syntax −
select *from yourTableName where REGEXP_INSTR(yourColumnName,yourSearchValue);
To understand the above syntax, let us first create a table −
mysql> create table demo64 −> ( −> id int not null auto_increment primary key, −> name varchar(40) −> ); Query OK, 0 rows affected (3.06 sec)
Insert some records into the table with the help of insert command −
mysql> insert into demo64(name) values('John Smith');
Query OK, 1 row affected (0.21 sec)
mysql> insert into demo64(name) values('John Doe');
Query OK, 1 row affected (0.15 sec)
mysql> insert into demo64(name) values('Chris Brown');
Query OK, 1 row affected (0.08 sec)
mysql> insert into demo64(name) values('David Miller');
Query OK, 1 row affected (0.20 sec)
mysql> insert into demo64(name) values('Carol Taylor');
Query OK, 1 row affected (0.10 sec)Display records from the table using select statement −
mysql> select *from demo64;
This will produce the following output −
+----+--------------+ | id | name | +----+--------------+ | 1 | John Smith | | 2 | John Doe | | 3 | Chris Brown | | 4 | David Miller | | 5 | Carol Taylor | +----+--------------+ 5 rows in set (0.00 sec)
Following is the query for field type search query −
mysql> select *from demo64 where REGEXP_INSTR(name,'John');
This will produce the following output −
+----+------------+ | id | name | +----+------------+ | 1 | John Smith | | 2 | John Doe | +----+------------+ 2 rows in set (0.00 sec)
