ERROR: ORA-00923: FROM keyword not found where expected - sql

Question

I tried to fetch data from a oracle sql table with the count of records. I tried like following,
SELECT *,
(COUNT(BRAND_ID) AS TOTAL)
FROM
(
SELECT BRAND_ID,
BRAND_CODE,
BRAND_TITLE
FROM BRAND
WHERE ACTIVE = '1'
ORDER BY BRAND_TITLE ASC
OFFSET 10 ROWS
FETCH NEXT 10 ROWS ONLY
) BRAND
LEFT JOIN
((
SELECT PRODUCT_ID,
PRODUCT_SKU_ID,
PRODUCT_WEB_ID,
PRODUCT_TITLE,
PRODUCT_SALES_PRICE,
PRODUCT_REGULAR_PRICE,
PRODUCT_RATING
FROM PRODUCT
WHERE
(
PRODUCT_TYPE='B'
OR PRODUCT_TYPE='R'
)
AND AVAILABILITY='1'
) PRDUCT ) ON BRAND.BRAND_CODE= PRDUCT.BRAND_CODE
When I'm executing this I got the following error,
ERROR: ORA-00923: FROM keyword not found where expected
How may I fix this.
Thanks in Advance!

Answer 1

I guess You should remove * from select statement in the first line. Try the below one.
SELECT (COUNT(BRAND_ID) AS TOTAL)
FROM
(
SELECT BRAND_ID,
BRAND_CODE,
BRAND_TITLE
FROM BRAND
WHERE ACTIVE = '1'
ORDER BY BRAND_TITLE ASC
OFFSET 10 ROWS
FETCH NEXT 10 ROWS ONLY
) BRAND
LEFT JOIN
((
SELECT PRODUCT_ID,
PRODUCT_SKU_ID,
PRODUCT_WEB_ID,
PRODUCT_TITLE,
PRODUCT_SALES_PRICE,
PRODUCT_REGULAR_PRICE,
PRODUCT_RATING
FROM PRODUCT
WHERE
(
PRODUCT_TYPE='B'
OR PRODUCT_TYPE='R'
)
AND AVAILABILITY='1'
) PRDUCT ) ON BRAND.BRAND_CODE= PRDUCT.BRAND_CODE

You are using a aggreagte function in the select statement . So you cannot simply call Select * for other columns.
First you should give an alias for the inside columns selected for easiness.
Then select that columns in the outside SELECT
Since one of the column in select is using agg function then a Group By should be done by other columns coming in Select.
Here for easiness i gave column name as c2,c3....rename as like u want.
If no alias is given u can specify the column as it is specified.
SELECT c2,c3,c4,c5,c6,c7,c8,c9,c10,
COUNT(BRAND_ID) AS TOTAL
FROM
(
SELECT BRAND_ID ,
BRAND_CODE AS c2,
BRAND_TITLE AS c3
FROM BRAND
WHERE ACTIVE = '1'
ORDER BY BRAND_TITLE ASC
OFFSET 10 ROWS
FETCH NEXT 10 ROWS ONLY
) BRAND
LEFT JOIN
((
SELECT PRODUCT_ID AS c4,
PRODUCT_SKU_ID AS c5,
PRODUCT_WEB_ID AS c6,
PRODUCT_TITLE AS c7,
PRODUCT_SALES_PRICE AS c8,
PRODUCT_REGULAR_PRICE AS c9,
PRODUCT_RATING AS c10
FROM PRODUCT
WHERE
(
PRODUCT_TYPE='B'
OR PRODUCT_TYPE='R'
)
AND AVAILABILITY='1'
) PRDUCT ) ON BRAND.BRAND_CODE= PRDUCT.BRAND_CODE
Group By c2,c3,c4,c5,c6,c7,c8,c9,c10

I don't have 12c, so can't test, but maybe this is what you're after?
SELECT *
FROM
(
SELECT BRAND_ID,
BRAND_CODE,
BRAND_TITLE
FROM (select b.*,
count(brand_id) over () total
from BRAND b
WHERE ACTIVE = '1'
ORDER BY BRAND_TITLE ASC
OFFSET 10 ROWS
FETCH NEXT 10 ROWS ONLY
) BRAND
LEFT JOIN
((
SELECT PRODUCT_ID,
PRODUCT_SKU_ID,
PRODUCT_WEB_ID,
PRODUCT_TITLE,
PRODUCT_SALES_PRICE,
PRODUCT_REGULAR_PRICE,
PRODUCT_RATING
FROM PRODUCT
WHERE
(
PRODUCT_TYPE='B'
OR PRODUCT_TYPE='R'
)
AND AVAILABILITY='1'
) PRDUCT ) ON BRAND.BRAND_CODE= PRDUCT.BRAND_CODE;
This uses an analytic query to get the count of all brand_ids over the whole table before you filter the rows. I'm not sure if you wanted the count per brand_id (count(*) over (partititon by brand_id) or perhaps the count of distinct brand_ids (count(distinct brand_id) over ()), though, so you'll have to play around with the count function to get the results you're after.
