To mix string and number, you need to use VARCHAR() data type. Following is the syntax −
CREATE TABLE yourTableName ( yourColumnName1 VARCHAR(40) );
Let us create a table −
mysql> create table demo28 −> ( −> id int not null auto_increment primary key, −> user_id varchar(40) −> ); Query OK, 0 rows affected (0.64 sec)
Insert some records into the table with the help of insert command −
mysql> insert into demo28(user_id) values('John_123'); Query OK, 1 row affected (0.13 sec) mysql> insert into demo28(user_id) values('David_44'); Query OK, 1 row affected (0.15 sec) mysql> insert into demo28(user_id) values('Mike99'); Query OK, 1 row affected (0.16 sec) mysql> insert into demo28(user_id) values('Sam101'); Query OK, 1 row affected (0.17 sec)
Display records from the table using select statement −
mysql> select *from demo28;
This will produce the following output −
+----+----------+ | id | user_id | +----+----------+ | 1 | John_123 | | 2 | David_44 | | 3 | Mike99 | | 4 | Sam101 | +----+----------+ 4 rows in set (0.00 sec)
