I am trying to figure out how to select the 1st property ID per client ID that gets associated to the Customer ID. Please help. How would I query this?
PropertyID ClientID CustomerID Date
10 1 35 2004
20 1 35 2004
30 2 35 2004
40 2 35 2004
50 3 35 2004
60 3 35 2004
70 4 35 2004
80 4 35 2004
90 5 35 2004
100 5 35 2004
110 6 35 2005
120 6 35 2005
130 7 35 2005
140 7 35 2005
150 8 35 2005
160 8 35 2005
170 9 35 2005

240 15 37 2007
260 16 37 2007
270 16 37 2007
Expected Result:
PropertyID ClientID CustomerID
10 1 35
30 2 35
50 3 35
70 4 35
90 5 35
110 6 35

170 9 35
220 15 37
260 16 37
Assuming by 1st you mean with lowest propertyId, you can use aggregation in subquery to find the lowest propertyId per clientId and then join the results with the original table to get the other corresponding columns.
select propertyId, clientId, customerId
from your_table t
join (
select clientId,
min(propertyId) as propertyId
from your_table
group by clientId
) t2 using (clientId, propertyId);
This assumes the propertyId is unique (per client at least).
Demo
SELECT MIN(PropertyID) AS PropertyID, ClientID, CustomerID
FROM table_name
GROUP BY ClientID,CustomerID;

So I wnat to get the result to match the two or three values from the column value and want the result
I made query like
SELECT DISTINCT user_id FROM user where value =123 AND value=523;
But it is not working please give solution how we get the result
A value in a row, as per your example, cannot be both 123 and 523. You have to use OR
SELECT DISTINCT(user_id) FROM user WHERE value=123 OR value=523;
Alternatively you can also use IN clause
SELECT DISTINCT user_id
FROM user
WHERE value IN (123, 523);
I have two tables "activity_stats" & "activity_stats_values"
activity_stats table
# id, activity_id, kyf_id, kyf_sort
618 84 5 1
619 84 6 2
638 84 4 3
activity_stats_values table
# id, activity_id, player_id, kyf_id, value
2563 84 46 5 45
2564 84 46 6 60
2587 84 47 5 10
2588 84 47 6 25
2589 84 49 5 10
2590 84 49 6 40
2591 84 48 5 30
2592 84 48 6 15
2594 84 46 4 NULL
2595 84 47 4 80
2596 84 48 4 NULL
2597 84 49 4 NULL
Requirement
players should be sorted by values in descending order. Meaning the player with highest value of first keyfigure(kyf_id , kyf_id position based on field "kyf_sort" of table "activity_stats") should be on top (then second key figure, then third key figure).
Expected output
# id, activity_id, player_id, kyf_id, value kyf_sort
2563 84 46 5 45 1
2564 84 46 6 60 2

OR playes ids in order [46,48,49,47]
I tried the following query
SELECT ac_st_v.activity_id,ac_st_v.player_id,ac_st_v.value,ac_st.kyf_id,ac_st.kyf_sort,pl.first_name ,
(select max(value)
from activity_stats_values
where activity_id=ac_st_v.activity_id
and kyf_id=ac_st.kyf_id
group by activity_id) as m_value
FROM teamplayer.activity_stats_values as ac_st_v
JOIN teamplayer.activity_stats as ac_st
ON ac_st_v.activity_id=ac_st.activity_id
AND ac_st_v.kyf_id=ac_st.kyf_id
JOIN teamplayer.players as pl
ON ac_st_v.player_id=pl.id
where ac_st_v.activity_id= 84
order by ac_st_v.player_id,ac_st.kyf_sort,m_value
Is there any way to sort the values like this?

order by prm.voucher_no
i tried inner join,distinct,distinct least,group by,temporary table,with clause all these method.. but no use every this gives duplicate row
How to solve this problem..

I think the problem is in your data model itself. Ideally, you would have a line_number field in both of your "detail" tables, and this would be used in the join:
create table purchase_request_details (
prm_voucher_no integer,
prm_voucher_line integer, // Add this
item_id integer,
request_quantity
)
create table purchase_order_details (
pom_voucher_no integer,
pom_voucher_line integer, // and this
approved_quantity integer,
rate integer
)
And then this query would give you the results you seek:
select
prm.prm_voucher_no,prm.project_id,prm.status_id,prd.request_quantity,
prd.item_id,pom.pom_voucher_no,pom.supplier_id,pod.rate,pod.approved_quantity
from
purchase_request_master prm
left join purchase_request_details prd on
prd.prm_voucher_no=prm.prm_voucher_no
left join purchase_order_master pom on
prm.prm_voucher_no=pom.prm_request_id
left join purchase_order_details pod on
pom.pom_voucher_no=pod.pom_voucher_no and
prd.prm_voucher_line = pod.pom_voucher_line // This is the key
where
prm.project_id=46 and
EXTRACT(MONTH FROM prm.request_Date) = 6 and
EXTRACT(YEAR FROM prm.request_Date) = 2016
order by prm.prm_voucher_no
If you have no ability to control the data model, then I think the best you can do is artificially add a line number. I don't recommend this at all, as you are presupposing a lot of things, most notably that the order of records in the one table automatically correlates to the order of records in the other -- and I'm betting that's far from a guarantee.
Adding a line number would be done using the row_number() analytic, and PostgreSQL has that but MySQL does not... you have both tags in your question. Which DBMS are you using?
If you can't add line numbers, can you add item_id to your purchase_order_details table? This would likely handle your issue, unless you can have the same item on multiple lines within a purchase request/order.
In the data you have above, a join on the requested quantity (prd.request_quantity = pod.approved_quantity) fixes your issue, but I am highly confident that this would burn you when you started running it against real data.
I have a matrix with rows grouped by Dept (Department). I am trying to get the actual hours / required hours percentage in a column for each row group, but I can only get the total %, not the % by group. Ex:
I should get this:
Total Employee Req Hrs Rep Hrs % Billable hrs % NonBill Hrs % Time Off %
Dept A Total 672 680 101 575 85 140 21 8 1
Emp1 168 170 101 150 89 50 29 0 0
Emp2 168 165 98 120 71 20 12 8 4
Emp3 168 175 104 155 92 20 12 0 0
Emp4 168 170 101 150 89 50 29 0 0
Dept B Total 420 428 102 365 87 80 19 4 .1
Emp5 168 170 101 150 89 50 29 0 0
Emp6 84 84 98 60 71 10 12 4 4
Emp7 168 175 104 155 92 20 12 0 0
G Total 1092 1108 101 940 86 190 17 12 1
But I get this:
Total Employee Req Hrs Rep Hrs % Billable hrs % NonBill Hrs % Time Off %
Dept A Total 1684 1675 101 1250 86 225 17 12 1
Emp1 168 170 101 150 89 50 29 0 0
Emp2 168 165 98 120 71 20 12 8 4
Emp3 168 175 104 155 92 20 12 0 0
Emp4 168 170 101 150 89 50 29 0 0
Dept B Total 1092 1108 101 1250 86 225 17 12 1
Emp5 168 170 101 150 89 50 29 0 0
Emp6 84 84 98 60 71 10 12 4 4
Emp7 168 175 104 155 92 20 12 0 0
G Total 1092 1108 101 940 86 190 17 12 1
The totals are correct but the % is wrong.
I have several Datasets because the report only runs the department you are in, except for the VPs who can see all departments.
I Insert the percentage columns into the matrix and have tried several expressions with no results including:
=Fields!ActHrs.Value/Fields!ReqHrs.Value
=Sum(Fields!ActHrs.Value, "Ut_Query")/Sum(Fields!ReqHrs.Value, "Ut_Query")
=Sum(Fields!ActHrs.Value, "Ut_Query","Dept")/Sum(Fields!ReqHrs.Value,
"Ut_Query","Dept")
=Sum(Fields!ActHrs.Value,"Dept", "Ut_Query")/Sum(Fields!ReqHrs.Value,
"Dept","Ut_Query")
Plus more I can't even remember.
I tried creating new groups, and even a new matrix.
There must be a simple way to get the percentage by group but I have not found an answer on any of the interned boards.
OK, I figured this out, but it doesn't make much sense. If I try:
=Textbox29/TextBox28 I get error messages about undefined variables.
If I go the the textbox properties and rename the textboxes to Act and Req and use:
=Act/Req I get the right answer.
I have table like
id userid semid courseid coursename total
1 36 17 13 CA 23
2 36 17 5 CB 46
3 36 17 8 CC 20
4 36 19 16 CD 34
5 36 19 13 CA 31
6 36 19 3 CA# 29
7 36 19 7 CE 60
8 36 10 9 CK 32
9 36 10 15 CH 56
I need average of semid for a userid i.e., SUM(courseid) /count (moduleid), It was showing 9 as module count, but I have only 3 modules.
This is my query
SELECT userid, SUM(total)/count(semid) FROM custom WHERE userid=36
just use the AVG( ) function
SELECT userid, semid, AVG(total)
FROM custom
WHERE userid = 36
GROUP BY userid, semid
SQLFiddle Demo
SELECT userid, SUM(total)/count(distinct semid) FROM custom WHERE userid=36
Try this query
There is MYSQL aggregate function AVG() for finding Average . #John Totet Woo has posted the answer.
