Error 1064 in SQL statement - mysql

Question

I have tried to run a SQL command but I am receiving this error:
#1064 - 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 ')
The SQL statement is
SELECT * ,
Match(product.title) against (query) + match(product.description) against (query1) +match(product.keyword) against (query2)+match(product.url) against (query2) + (average(review.rating)/100*count(productid))+(100/price)+(site.domainauthority/25)+(10-
CASE
WHEN lcase(seller.city) = lcase(city) THEN TRUNCATE(( 6371 * acos( cos( radians( 23 ) ) * cos( radians( seller.latitude ) ) * cos( radians( seller.longitude ) - radians(24) ) + sin( radians( 24 ) ) * sin( radians( seller.latitude ) ) ) ),1))
ELSE + 0
END AS score
FROM product,
productimages,
review,
seller,
site
WHERE distance < 10
AND productimage.id=product.id
AND product.sellerid =seller.id
AND product.siteid-site.id
AND productmeta.id = product.id
AND review.productid = product.id
AND ((
seller.deliverabletype = "international")
OR (
seller.deliverabletype = "country"
AND seller.country = 'country')
OR (
seller.deliverabletype = "state"
AND seller.country = 'country')
OR
OR (
seller.deliverabletype = "city"
AND seller.country = 'city'))
GROUP BY product.id mysql sql-server

Answer 1

The query was not well formed. One of the closing parenthesis should be at the end.
try this.
TRUNCATE(
( 6371 * acos(
cos( radians( 23 ) ) * cos( radians( seller.latitude ) ) *
cos( radians( seller.longitude ) - radians(24) ) +
sin( radians( 24 ) ) * sin( radians( seller.latitude ) )
)
),1)
ELSE + 0
END) AS score
