Combining SQL Query Results Into One Table

I'm trying to combine queries so the results are in one table.

SELECT sku.idsku, amaterial.material
FROM sku
INNER JOIN amaterial ON sku.idsku = amaterial.sku_idsku
LIMIT 0 , 30

Produces:

idsku material

13 Steel

SELECT sku.idsku, amcolor.color
FROM sku
INNER JOIN amcolor ON sku.idsku = amcolor.sku_id开发者_Go百科sku

Produces

idsku color

13 red

17 purple

SELECT sku.idsku, atype.type
FROM sku
INNER JOIN atype ON sku.idsku = atype.sku_idsku

Produces

idsku type

13 labret

17 barbell

What I want to create is a table as follows:

idsku material color type

13 steel red labret

17 ---- purple barbell

Thanks in advance for your help.

what if you put all your queries into one?

 SELECT sku.idsku, amaterial.material, amcolor.color, atype.type
 FROM sku sku
 INNER JOIN amaterial ON sku.idsku = amaterial.sku_idsku
 INNER JOIN amcolor ON sku.idsku = amcolor.sku_idsku
 INNER JOIN atype ON sku.idsku = atype.sku_idsku
 LIMIT 0 , 30
