Here is what I have done using MySQL:

** Create a table:
mysql> CREATE TABLE `tablename` (
-> `id` tinyint(3) unsigned NOT NULL auto_increment,
-> `name` char(20) default '0',
-> PRIMARY KEY (`id`)
-> );
Query OK, 0 rows affected (0.06 sec)

** Then insert some data into the table:
mysql> INSERT INTO tablename (id, name) VALUES (NULL, '\'Albert');
Query OK, 1 row affected (0.00 sec)

mysql> INSERT INTO tablename (id, name) VALUES (NULL, '\'Piet');
Query OK, 1 row affected (0.00 sec)

mysql> INSERT INTO tablename (id, name) VALUES (NULL, '\'Koos');
Query OK, 1 row affected (0.00 sec)

mysql> INSERT INTO tablename (id, name) VALUES (NULL, 'Jan');
Query OK, 1 row affected (0.00 sec)

mysql> INSERT INTO tablename (id, name) VALUES (NULL, 'Gert');
Query OK, 1 row affected (0.00 sec)

** Then retrieve all the record starting with an apostrophe ('):
mysql> SELECT * FROM tablename WHERE name LIKE '\'%';
+----+---------+
| id | name |
+----+---------+
| 1 | 'Albert |
| 2 | 'Piet |
| 3 | 'Koos |
+----+---------+
3 rows in set (0.00 sec)

Hope it helps

Albert
