How to combine 2 select in one query?

I have sql query which selects some stuff from first table using params from second, and then i need to get some columns from second table in addition to first Code looks like that

SELECT 
  entry AS entry,
  ItemLevel AS ItemLevel,
  RequiredLevel AS RequiredLevel,
  InventoryType AS InventoryType,
  Quality AS Quality,
  class AS class,
  subclass AS subclass 
FROM item_template 
WHERE entry IN (SELECT entry FROM locales_item WHERE name_loc8 LIKE ? ) 
ORDER BY ItemLevel DESC; 

SELECT entry, name_loc8, description_loc8 FROM locales_item WHERE name_loc8 LIKE ?

But it's throws an error

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SELECT entry, name_loc8, description_loc8 FROM locales_item WHERE name_loc8 LIKE' at line 1

How to solve this?

if entry is a unique key then you can join the two tables together like so

SELECT it.stuff, li.stuff 
FROM item_template it 
JOIN locales_item li ON li.entry = it.entry
WHERE li.name_loc8 LIKE "some string"
ORDER BY it.ItemLevel DESC

this removes the need for your dependent subquery with the IN() since joining the table already filters like the where would

Try This 

SELECT 
  t1.entry AS entry,
  t2.name_loc8,
  t2.description_loc8
  t1.ItemLevel AS ItemLevel,
  t1.RequiredLevel AS RequiredLevel,
  t1.InventoryType AS InventoryType,
  t1.Quality AS Quality,
  t1.class AS class,
  subclass AS subclass 
FROM item_template t1
left join locales_item t2 on t1.entry = t2.entry 
WHERE t2.name_loc8 LIKE '%addyourtexthere%'----just change the text between the percent signs to the string your looking for  
ORDER BY ItemLevel DESC;

and also you don't need the "AS" after every column if you're calling it the same name.

If you want to join the results of two queries you can use UNION, however I think what you are after here is joining the matching records in two tables into a single query which you can do with JOIN.

With your example, I think what you're looking for is a query like this:

SELECT t.entry          AS entry,
       t.ItemLevel      AS ItemLevel,
       t.RequiredLevel  AS RequiredLevel,
       t.InventoryType  AS InventoryType,
       t.Quality        AS Quality,
       t.class          AS class,
       t.subclass       AS subclass,
       l.entry          AS locale_entry,
       l.name_loc8      AS name_loc8,
       l.description_loc8 AS description_loc8
FROM item_template t
INNER JOIN locales_item l ON l.entry = t.entry
WHERE l.name_loc8 LIKE ?
ORDER BY t.ItemLevel DESC;

you should use join to connect the two tables:

SELECT 
  item_template.entry AS entry,
  ItemLevel AS ItemLevel,
  RequiredLevel AS RequiredLevel,
  InventoryType AS InventoryType,
  Quality AS Quality,
  class AS class,
  subclass AS subclass 
FROM item_template inner join locales_item 
on item_template.entry = locales_item.entry 
 WHERE name_loc8 LIKE ?  
ORDER BY ItemLevel DESC;
