Log on to the MySQL client tool mysql:

DanielMorgan@DANPC ~
$ mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 7 to server version: 3.23.51-nt

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

Change to a database:

mysql> use test
Database changed

Create a database table named hello_world_test with the columns hello_id and
hello_desc.
hello_id is the id to this table and hello_desc is an attribute that is a
description.

mysql> create table hello_world_test (
    -> hello_id varchar(2),
    -> hello_desc text);
Query OK, 0 rows affected (0.01 sec)

Insert a row into the new table named hello_world_test
with hello_id set to 'HW'
and hello_desc set to 'Hello World'.

mysql> insert into hello_world_test (hello_id, hello_desc) values
('HW','Hello W
orld');
Query OK, 1 row affected (0.00 sec)

Verify the data in the table.

mysql> select * from hello_world_test;
+----------+-------------+
| hello_id | hello_desc  |
+----------+-------------+
| HW       | Hello World |
+----------+-------------+
1 row in set (0.02 sec)

Now, create the SQL statement you will use in your C# program.

mysql> select hello_desc from hello_world_test where hello_id = 'HW';
+-------------+
| hello_desc  |
+-------------+
| Hello World |
+-------------+
1 row in set (0.02 sec)
