This is a snapshot of my MySQL table:

Is it possible to write a query to get such a pivot table like output…

Answer 1

You can use CASE statement on this to pivot your table.

SELECT  url_host,
        COUNT(CASE WHEN post_ID = -1 THEN 1 ELSE NULL END) Negative_One,
        COUNT(CASE WHEN post_ID = 0 THEN 1 ELSE NULL END) Zero,
        COUNT(CASE WHEN post_ID > 0 THEN 1 ELSE NULL END) Greater_Zero
FROM tableName
GROUP BY url_host
