Help me to build SQL Query to get Count in Result Table.
Try this
SELECT Status, COUNT(*) FROM
(SELECT a.Status FROM TableA AS a
UNION ALL
SELECT b.Status FROM TableB AS b) UN
GROUP BY Status
SELECT STATUS, COUNT(*) FROM
(SELECT STATUS FROM TABLE1

I have a requirement :
ID Quantity
1 5
1 4
1 2
1 4
2 1
2 2
2 3
3 1
3 3
3 2
Output required :
ID Quantity

I have tried the below query on MySQL but unable to get appropriate result.
SELECT
a.id, sum(b.Quantity)
FROM
table_name a
INNER JOIN
table_name b
ON a.id = b.id
group by
a.id, b.Quantity
Just remove b.Quantity from group by statement. SQL fiddle
SELECT
a.id, sum(b.Quantity)
FROM
table_name a
INNER JOIN
table_name b
ON a.id = b.id
group by
a.id

SELECT id, SUM(quantity)
FROM `table_name`
GROUP BY id
You don't need any join. Simply try:
select id,sum(quantity) from table_name group by id
Use GROUP BY clause along with sum() like the query below-
select ID, sum(Quantity) FROM table_name GROUP BY ID;
I have table User, Company, ParentCompany and table Goal.
Each Company have ParentCompany, and each User inside one Company. Goal have number of action, and type of Goal, user who execute the goal, and time executed.
I want to calculate the number of action in a date range for each type of Goal, for each user, company, and parent_company. Number of action for each company equal to sum of action for user that reside in that company.
More or less after some join query, I able to get this table below, where column id is id of company, parent_id is id of companyparent, and num is number of goal for all user inside of id company.
id parent_id num
----------- -------------------- -----------------------
1 3 1
2 1 2
3 1 1
4 2 4
Now I want to make it like below:
id parent_id sum_id sum_parent
----------- -------------------- -------------- -------------
1 3 1 1
2 1 2 3
3 1 1 3
4 2 4 4
How can I make it works? I can get one of the value (sum_id or sum_parent) with GROUP BY,
SELECT id,SUM(num) AS sum_id FROM tableA GROUP BY id
or
SELECT parent_id,SUM(num) AS sum_parent FROM tableA GROUP BY parent_id
but is there any way to make it only in one query? tableA results from query with 5 join inside.
Try this:
SELECT a.id, a.parent_id, a.sum_id, b.sum_parent
FROM (SELECT id, parent_id, SUM(num) sum_id FROM tableA a GROUP BY id) a
INNER JOIN (SELECT parent_id, SUM(num) sum_parent FROM tableA a GROUP BY parent_id) b ON a.parent_id = b.parent_id
Try this :
SELECT
t1.id, t1.parent_id, t1.sum_id, t2.sum_parent
FROM
(SELECT id, parent_id, SUM(num) AS sum_id FROM mytable GROUP BY id) t1
INNER JOIN
(SELECT parent_id, SUM(num) AS sum_parent FROM mytable GROUP BY parent_id) t2
ON t1.parent_id = t2.parent_id
Apparently what I want can be done with WITH ROLLUP statement. (http://dev.mysql.com/doc/refman/5.0/en/group-by-modifiers.html)
With
SELECT id,sum(num) FROM tableA GROUP BY parent_id, id WITH ROLLUP;
will results in
parent_id id sum(num)

I have a table like this:
**lead_id** **form_id** **field_number** **value**
1 2 1 Richard
1 2 2 Garriot
2 2 1 Hellen
2 2 2 Garriot
3 2 1 Richard
3 2 2 Douglas
4 2 1 Tomas
4 2 2 Anderson
Where field_number = 1 is the name and field_number = 2 is the surname.
I would like to find entries that are equal by name OR surname and group them by lead_id, so the output could be like this:
1
2
3
Any thoughts on how this can be done?
This should work and be reasonably efficient (depending upon indexes):
select distinct lead_id
from tablename as t1
where exists (
select 1
from tablename as t2
where t1.field_number = t2.field_number
and t1.value = t2.value
and t1.lead_id <> t2.lead_id
)
Select leadid from (
Select DISTINCT leadid,value from tablename
Where fieldnumber=1
Group by leadid,value
Having count(value) >1
Union all
Select DISTINCT leadid,value from tablename
Where fieldnumber=2
Group by leadid,value
Having count(value) >1
) as temp
Surely there is a faster option
I am writing a query to grab the items that a specific user_id was the first to use. Here is some sample data -
item_id used_user_id date_used
1 1 2012-08-25
1 2 2012-08-26
1 3 2012-08-27
2 2 2012-08-27
3 1 2012-08-27
4 1 2012-08-21
4 3 2012-08-24
5 3 2012-08-23
query
select item_id as inner_item_id, ( select used_user_id
from test
where test.item_id = inner_item_id
order by date_used asc
limit 1 ) as first_to_use_it
from test
where used_user_id = 1
group by item_id
It returns the correct values
inner_item_id first_to_use_it
1 1
3 1
4 1
but the query is VERY slow on a giant table. Is there a certain index that I can use or a better query that I can write?
i can't get exactly what you mean because in your inner query you have sorted it by their used_user_id and and on your outer query you have filtered it also by their userid. Why not do this directly?
SELECT DISTINCT item_id AS inner_item_id,
used_user_id AS first_to_use_it
FROM test
WHERE used_user_id = 1
UPDATE 1
SELECT b.item_id,
b.used_user_id AS first_to_use_it
FROM
(
SELECT item_ID, MIN(date_used) minDate
FROM tableName
GROUP BY item_ID
) a
INNER JOIN tableName b
ON a.item_ID = b.item_ID AND
a.minDate = b.date_used
WHERE b.used_user_id = 1
I have two tables:
builders
b_id fk_c_id
1 1
2 1
3 1
4 1
5 1
6 2
7 2
subbuilders
fk_b_id sb_id
1 2
1 3
1 4
2 5
6 7
and i want Distinct b_id which are not exist in subbuilders table and must have same fk_c_id
I create:
SELECT DISTINCT b.id FROM pms_builder_to_subbuilders bsb
LEFT JOIN pms_builders b ON b.id = bsb.sb_id WHERE b.fk_c_id = '1'
but it show Distinct records from subbuilders.
You can get the desired results with the following query:
SELECT DISTINCT b.b_id FROM builders b LEFT JOIN subbuilders sb ON sb.fk_b_id = b.b_id WHERE b.fk_c_id = '1' AND ISNULL(fk_b_id);
i think you want this query:
SELECT DISTINCT b_ID
FROM builders
WHERE b_ID NOT IN
(SELECT DISTINCT fk_b_id FROM subbuilders)
but it returns
b_ID
========

7
but i didn't understand your statement: must have same fk_c_id. What do you mean by that?
b_id = fk_c_id
if that's the case then there will be no rows returned because only record 1 has the same b_ID and fk_c_id but exists in table subbuilders
