Answer 1

MySQL wildcards: _ AND % (in conjunction with keyword LIKE)

---

_ denotes a single character

SELECT name FROM colors WHERE name LIKE 'gr_y';

Output: ‘grAy’, ‘grEy’.

---

% denotes any number of characters

SELECT name FROM colors WHERE name LIKE 'gr%';

Output: ‘grAY’, ‘grEY’, ‘grEEN’.

---

You can use both _ and % multiple times

SELECT name FROM color WHERE name LIKE '_ra%';

Output: ‘GraY’, ‘OraNGE’.

In your case, if you want to list the names containing starting with either ‘ABC’ or ‘DEF’, your query would be like this:

SELECT id,name FROM Regist
    WHERE name LIKE 'ABC%' OR name LIKE 'DEF%'
    ORDER BY date

If you want your names to contain the strings ‘ABC’ OR ‘DEF’ anywhere inside, your query would be:

SELECT id,name FROM Regist
    WHERE name LIKE '%ABC%' OR name LIKE '%DEF%'
    ORDER BY date

Finally, if you want your names to contain both ‘ABC’ AND ‘DEF’ you could use:

SELECT id,name FROM Regist
    WHERE name LIKE '%ABC%DEF%' OR name LIKE '%DEF%ABC%'
    ORDER BY date
