A have a number of similar tables and what I want to do is to get the count of records grouped by day of week. All tables have date as an indexed unique column but the actual timestamps differs and have no relation. For one table I use this simple querry:
Select DatePart(dw,dato) AS DOW, Count(dato) AS NOR FROM AWP2
where dato > '2006-08-11'
Group By DatePart(dw,dato)
Trying to join two or more tables in all sorts of variants of this:
Select datePart(dw,a1.dato) AS DOW1,Count(a1.dato) [Amount 1],
datePart(dw,a2.dato) AS DOW2, Count(a2.dato) [Amount 2]
FROM AWP1 A1 Inner Join AWP2 A2 on datePart(dw,a1.dato) = datePart(dw,a2.dato)
Where a1.dato > '2006-08-11' AND a2.dato > '2006-08-11'
Group By datePart(dw,a1.dato), datePart(dw,a2.dato)
This is so complicated (for me) because I usually only work with single table and simple queries (SELECT, INSERT, UPDATE), but now I am in a situation where I am stuck.
What I am trying to archive is that: when a project manager logged-into his/her account, a grid-view will show a quick overview for all of his/her projects (id, created date, name and how many files are in pending) like below picture:
3 tables will be involved are:
Sample data for manager_id = 11
I tried this query but it not worked, it seems to display all columns right but the COUNT pending files column (assume the manager_id = 11)
SELECT COUNT(file_id) as 'Pending files', projects.project_id, projects.project_name, projects.status, projects.start_date FROM ((project_manager INNER JOIN files ON project_manager.mag_id = files.manager_id AND project_manager.mag_id = 11 AND file_status = 'Pending') INNER JOIN projects ON projects.project_id = project_manager.project_id) GROUP BY projects.project_id, projects.project_name, projects.status, projects.start_date ORDER BY projects.status, projects.start_date DESC
Hi All, I am trying to achieve loading a fact table using my stage and dimesion data , I was planning to use a Lookup transformation to do this, however I am supposed to use a substring task to because the data in the stage table is in adifferent format from that in the dimensions, how do I incorporate this substring task within the data flow, any help is appreciated.
select centerid from GetChildCenter(@Centerid) union select centerid from getParentCenter(@Centerid) } as Center c
on c.Centerid = client.Centerid
Query 2
declare @Center table ( centerid int) insert into @Center
select centerid from getchildCenter(@Centerid) union all select centerid from getparentcenter(@Centerid)
Select Clinetid from clinet inner join @Center c on c.Centerid = client.Centerid
I just want to know which one is better performance wise.. because there is millions of rows for table center which is used by function getChildCenter() and GetparentCenter()
I am running into trouble performing a second join on a column while using aggregate functions over that table.
What I think is happening is that the aggregate values (sum, avg, count) are being multiplied because I am joining on the same table a second time, but I don't know how to fix or avoid this problem.
Here's the query:
---
SELECT CAST(ro.xing_tc_no AS INT) AS loc_id, SUM(ro.total_fatal) AS tot_fatal, SUM(ro.total_serious) AS tot_serious, SUM(ro.total_minor) AS tot_minor, COUNT(ro.report_no) AS tot_accidents, AVG(ro.NO_OCCUPANTS) AS num_occupants
FROM UserHotspots uh
LEFT JOIN rods_k_crossing AS rkc ON rkc.location_id = uh.CrossingID
LEFT JOIN rods_occurrence AS ro ON rkc.tc_location_nbr = ro.xing_tc_no
GROUP BY ro.xing_tc_no
---
The second join is also performed on rods_k_crossing and that is when the sums, avgs, and counts get multiplied. If I take that second join out the numbers come out fine.
I want to join a table valued function but function parameter should left joined table's primary key .... this is posible in oracle by pipeline method .. eg.. SELECT A.Col1,A.Col2,B.Col1,B.Col2 FROM Tab As A LEFT OUTER JOIN TblFunction(A.Pkey) B ON A.Col1 = B.Col1
Hi there. I've hit some gap in my SQL fundementals. I'm playing with table-valued functions but I can't figure out how to join those results with another table. I found another way to hit my immediate need with a scalar function, but ultimately I'm going to need to use some approach like this. What am I misunderstanding here?
The Given Objects: function Split(stringToSplit, delimiter) returns table (column: token) table Words (column: Words.word) -- table of predefined words table Sentences (column: Sentences.sentence) -- table of sentences; tokens may not be in Words table, etc
The Problems: 1) how do I query a set of Sentences and their Tokens? (using Split) 2) how do I join tables Sentences and Words using the Split function?
The Attempts: A) select word, sentence, token from Words, Sentences, dbo.Split(sentence, ' ') -- implicitly joins Split result with Sentences? where word = token
resulting error: "'sentence' is not a recognized OPTIMIZER LOCK HINTS option."
B) select word, sentence from Words, Sentences where word in (select token from dbo.Split(sentence, ' ')) -- correlated subquery?
resulting error: "'sentence' is not a recognized OPTIMIZER LOCK HINTS option."
Hello, thanks in advance for reading this. I am having difficulty trying to get a statement to work.
There is a MAIN table: ItemNo int identity(1,0), ItemType tinyint
There is a WETPAINT table: ItemNo int, Color varchar(20)
There is a DRYPAINT table: ItemNo int, Color varchar(20)
Now, what I want to do is JOIN the MAIN table to either the WETPAINT table or the DRYPAINT table depending on the value of MAIN.ItemType
So I created a table function called getTable:
CREATE FUNCTION [dbo].[gettable] ( @ItemType int = 1 ) RETURNS @thistable TABLE ( Color varchar(20)
) AS BEGIN if @ItemType = 1 insert into @thistable (color) select color from WETPAINT if @ItemType = 2 insert into @thistable (color) select color from DRYPAINT RETURN END
This is all fine and dandy if I iterate through the MAIN table one row at a time, but how can I JOIN the tables, like:
SELECT MAIN.ItemNo, a.Color FROM MAIN INNER JOIN gettable(Main.ItemNo) as a ON a.ItemNo = MAIN.ItemNo
Obviously, there is more than one field in the DRYPAINT and WETPAINT tables, and there is a need to have both tables instead of combining them into one.
Any help in how to create a table alias by passing a value from the select statement would be greatly appreciated! Thanks again.
PS -- I am trying to create a view with this, so I can't use variables and iterate through the MAIN table one row at a time.
I'm having some performance issues with a TSQL query. It's a complex statement but the main issue is the correlated query.
How can I convert this
SELECT TOP 5 (SELECT SUM(lt2.col3) FROM dbo.MyTable2 lt2 WHERElt2.col1 = lt.col1 AND lt2.col2 = lt.col2 AND lt2.id = lt.id ) AS Result FROM dbo.MyTable1 t1 ... to an inner join or a sql2012 window function?
By the way, I just added the TOP 5 myself while testing. It's not in the main query.
I have a few tables I am trying to join to create a report. Everything was working fine until I tried to add an aggregate Sum function to a column (MaxCap) in table ctfBarn.

i've two tables. such as tableA and table B table A has a column named CreatedBY and table B the same column.. now i need to get only the rows which match with table A's createdby column.. suppose tableA has only 2 values. when i make the join with tableB it shows as 4 values
I need to perform a join on six different tables to produce a report. The biggest join I have ever done has been four tables. The way I did that query was to join three tables and then to perform the final select on the three table join. Can anyone give me some advice. Should I use the same approach? Or can I just continue to use the keyword INNER JOIN to perform the joins?
select left(orders.orderdate,11) as date, orderdetails.partnumber, SUM(orderdetails.qty) as total from orderdetails, orders where orderdetails.partnumber is not null and orderdetails.order_id = orders.order_id and orders.orderdate >= {ts'2001-05-01 00:00:00'} and orders.orderdate <= {ts'2001-05-31 23:59:59'} group by orders.orderdate, orderdetails.partnumber order by orders.orderdate, total
But I do not have part that have null orders. My goal is to get
1) Get all part numbers, qty in the month of May. 2) at the end attach all partnumbers that have null ordered values to see which one have no orders.
I have 2 tables. One with col1,col2 and second one with col1,col2,col3. My requirement is to compare col1,col2 of t1 with t2 and update only changed records in t2. How to implement? Please advise.
I've tried an outer left join but cannot get the right data. Basically everything from the timecard table and the leftovers from the default table with descriptions for all.
I've got two tables, one called clientsharedeals and the clientorderdeals. In the first table, I have four fields (Rundate, Accno, Dealid, Nominal) that I need to sum(Nominal), grouping by dealid.
Once I've done this, I need to join to clientorderdeals, also having the same fields plus one extra (Rundate, Accno, Dealid, Nominal and Dealseq). Because of Dealseq, I can have more than one row in the table, matching (Rundate, Accno, Dealid, Nominal) of the first table. However, Dealseq increments, so I need to select max(Dealseq).
My query is doubling up on nominal because in my select statement, I am only using one account number, so I know what the value is for nominal and there are two rows in clientorderdeals - and it is not selecting max(dealseq) but both.
Could somebody please explain to me how do we join a table onto itself as that is what I was advised to do but I can't quite get where I want to go.
What I want to do is list values from a table,but those values can be just a quote (what would cost if they decided to go for that option) or those values can represent what was spent and invoiced, what is confusing me is that all of that gets saved in the same table and in same columns, so what was quoted for example for AirFares and what was spent gets saved in the same record but when it is "quoted amount" then ID = 1 but when it is invoiced ID = -1 and that is how we know what was quoted and what was invoiced.
But I need to split that one field into two columns one showing AirFareQuoted and one AirFareInvoiced and i have no idea how to achieve this.
hi, I knew how to join 2 tables but i have a process to select 3 tables. I have a sample table and field below. I want to join Parts & Orders using field Prt_no and Supplier & Parts using field Sup _code
Hey Folks, I am stuck at one place in data migration........ I have the following source tables having no PK / INDEX / Constraint defined on any of them........
T1 ( ID1 INT, STYLE VARCHAR(34) )
T2 ( COL_ID VARCHAR(34), OBJ_ID VARCHAR(34) )
T3 ( OUT_ID VARCHAR(34), ITEM VARCHAR(34), )
And here is the relation..........
Quote: T1.STYLE = T2.COL_ID
T2.OBJ_ID = T3.OUT_ID
T3.ITEM = T2.COL_ID
Here is what I have tried with.........
Quote: SELECT * FROM T3 WHERE ITEM IN ( SELECT COL_ID FROM T1 INNER JOIN T2 ON T1.STYLE = T2.COL_ID INNER JOIN T3 ON T2.OBJ_ID = T3.OUT_ID )
But this query is not helping me out. I mean the number of output records are 0.
Now can any one suggest me a join that includes all the 3 tables, or finetune my query?
