{code}
Many (total of 42) mondrian queries regressed. All of them missing rows in the returned result set.
Here is an example, query447.q
{code}
SELECT time_by_day.the_year AS c0,
product_class.product_family AS c1,
customer.state_province AS c2,
customer.city AS c3,
Sum(sales_fact_1997.unit_sales) AS m0
FROM time_by_day AS time_by_day,
sales_fact_1997 AS sales_fact_1997,
product_class AS product_class,
product AS product,
customer AS customer
WHERE sales_fact_1997.time_id = time_by_day.time_id
AND time_by_day.the_year = 1997
AND sales_fact_1997.product_id = product.product_id
AND product.product_class_id = product_class.product_class_id
AND product_class.product_family = 'Drink'
AND sales_fact_1997.customer_id = customer.customer_id
AND customer.state_province = 'WA'
AND customer.city IN ( 'Anacortes', 'Ballard', 'Bellingham', 'Bremerton',
'Burien', 'Edmonds', 'Everett', 'Issaquah',
'Kirkland', 'Lynnwood', 'Marysville', 'Olympia',
'Port Orchard', 'Puyallup', 'Redmond', 'Renton',
'Seattle', 'Sedro Woolley', 'Spokane', 'Tacoma',
'Walla Walla', 'Yakima' )
GROUP BY time_by_day.the_year,
product_class.product_family,
customer.state_province,
customer.city;
{code}
This query should return the following result:
{code}
[root@qa-node120 mondrian]# cat query447.e
1997 Drink WA Walla Walla 191.0000
1997 Drink WA Issaquah 203.0000
1997 Drink WA Everett 208.0000
1997 Drink WA Olympia 1066.0000
1997 Drink WA Edmonds 166.0000
1997 Drink WA Bremerton 1160.0000
1997 Drink WA Renton 225.0000
1997 Drink WA Bellingham 68.0000
1997 Drink WA Ballard 214.0000
1997 Drink WA Burien 251.0000
1997 Drink WA Seattle 168.0000
1997 Drink WA Redmond 137.0000
1997 Drink WA Lynnwood 201.0000
1997 Drink WA Puyallup 1040.0000
1997 Drink WA Tacoma 986.0000
1997 Drink WA Kirkland 247.0000
1997 Drink WA Sedro Woolley 58.0000
1997 Drink WA Yakima 1159.0000
1997 Drink WA Port Orchard 1128.0000
1997 Drink WA Spokane 2238.0000
1997 Drink WA Anacortes 82.0000
1997 Drink WA Marysville 193.0000
{code}
But drill now returns:
{code}
1997 Drink WA Sedro Woolley 58.0000
{code}
Here is the plan:
