I have a subquery that grabs all the sales reps with less then 6 visits. Only problem is, when i have a date when there are any number of sales reps that dont make visits, so the column would be null, they dont show up. I want to display these, because this report is supposed to show the visits made, so if they made none, i want it to show zero, instead of not showing the whole date column, since zero visits were made on that date that were below 6 and more then zero. Here's my stored procedure: (the subquery is highlighted)

i am trying to find a way to link an 'initial' Sale ID of a product to 'future' Sale IDs of products that will trace back to the original Sale ID.For example, if I call the original sale , 'Sale ID #123', how can i link future Sale ID's (child[ren]) and all future sales to the original Sale ID #123? Can I use a Surrogate Key or similar function?
Parent:Sale ID #123 Children: Sale ID # 456, Sale ID #789, Sale ID #.....
how I can link the original Sales ID (Parent) to Sale ID's (child[ren]) of future purchases currently existing and in the future going forward?
I am trying to think my way through a solution which I believe others have probably come across... I am trying to implement a matching routine wherein I need to match an address against a high value and a low value (or, for that matter an input date vs. a start and end date) to return the desired row ... i.e. if I were to use a straight vb program I would just use the following lookup:
" WHERE zip_code = @zip_code AND addr_prim_lo <= @street_number AND addr_prim_hi >= @street_number " & _
" AND addr_prim_oe = @addr_prim_oe AND street_pre = @street_pre AND street_name = @street_name " & _
" AND street_suff = @street_suff AND street_post = @street_post " & _
" AND (expiry_date = '' OR expiry_date = '00000000' OR expiry_date > @expiry_date)" & _
" GROUP BY fire_ID, police_ID, fire_opt_in_out, police_opt_in_out"
My question, then, is how would you perform this type of query using a lookup / merge join or script? I have not found a way to implement a way to set the input columns? I can set the straight matches without a problem, i.e. lookup zip code = input zip code, but can't think of the correct way to set comparisons, i.e. lookup value 1 <= input value AND lookup value 2 >= input value
I need to list customers in a table that represents sales over the years.
I have tables:
Customers -> id | name |... Orders -> id | idCustomer | date | ... Products -> id | idOrder | unitprice | quantity | ...
I am using this SQL but it only gets one year:
SELECT customers.name , SUM(unitprice*qt) AS total FROM Products INNER JOIN Orders ON Orders.id = Products.idOrder INNER JOIN Customers ON Customers.id = Orders.idCustomer WHERE year(date)=2014 GROUP BY customers.name ORDER BY 2 DESC
I need something like this:
customer | total sales 204 | total sales | 2015 | total sales (2014 + 2015) -------- customer A | 1000$ | 2000$ | 3000$ customer B | 100$ | 100$ | 200$
Is it possible to retrieve these values in a single SQL query for multiple years and grand total?
I want to calculate the sum of actual sales until a date and forecast sales after a date.I am not sure what the best approach to this problem is, but I have tried my best with the following approach. Any better ways to solve this (using DAX).
I have created a parameter table that offers the last date of each month as possible choices to the user. I have tried to create a measure that sums actual sales up until this date.
Folks,My secnario involves two tables - ObservationRegister, and Person.ObservationRegister contains most of the "useful" fields, includingthe UserID of the person that raised the record, and the UserID of theperson to whom the record was assigned for action. I need to write aquery to return all values in the ObservationRegister record, butinstead of returning the UserIDs, I need to look up the actual name,by looking up the name and userID in the Person table... doing thatonce (for just one of the UserID fields) is easy - a quick inner joindoes the job - but I effectively need to join to the Person table"twice", for different keys....Help? Please!? :)Steve
Hello Experts, Been struggling with this issue all morning and beginning to get a headache. Essentialy my problem is this. I have a gridview control that ive bound to datasource where the select statement is using an inner join to retrieve textual info from one table in refernce to an object_id contained within both. i.e SelectCommand="SELECT 'multiple fields from both tables'FROM ZCRMTAB_ACTIVITY INNER JOIN ZCRMTAB_ACT_LOG ON ZCRMTAB_ACT_LOG.OBJECT_ID = ZCRMTAB_ACTIVITY.OBJECT_ID WHERE (ZCRMTAB_ACTIVITY.REF_CUST_NO = @REF_CUST_NO) ORDER BY ZCRMTAB_ACTIVITY.CREATED_AT DESC"> <SelectParameters><asp:QueryStringParameter Name="fieldName" QueryStringField="value" Type="String" /> My problem is that this returns individual row results and are displayed on individual lines. Where the object_id is the same i want all the textual info to be displayed within the same row. Does anyone know how i can accomplish this? Thanks in advance
Is there a way to join tables that have multiple matches to each other (2 records in one table and 2 in another) so that you get 2 records returned instead of 4 with only 1 JOIN ON qualifier?
In our warehouse DB, there is a master location table, an inventory location table, and physical table for counting all product in the warehouse. The master location table has one record per location, but there could be multiple items in that location so my outer join from the master location to the inventory table returns something like:
select M.MASTER_LOC, C.AS ORIG_ITEM, C.ORIG_LOT, C.ORIG_QTY from M_LOC M LEFT OUTER JOIN C_INVT C ON M.MASTER_LOC = C.INVT_LOC order by M.LOC_CODE
My join is returning 4 rows for location 01-03-A which I understand, but I'm wondering if I can sort within the join or make some temp tables so that instead of:
select M.MASTER_LOC, C.AS ORIG_ITEM, C.ORIG_LOT, C.ORIG_QTY, E.AS CNTD_ITEM, E.CNTD_LOT, E.CNTD_QTY from M_LOC M LEFT OUTER JOIN C_INVT C ON M.MASTER_LOC = C.INVT_LOC LEFT OUTER JOIN E_PHYS_INVT E ON M.MASTER_LOC = E.LOC_CODE order by M.LOC_CODE
We're using MS Access 2010 as a frontend to an SQL server back-end. From Access, I can run read-only queries and pass-through queries. I'd like to use a local Access table as part of a join to server data. As a non-pass-through query, it's slow; about 5 min to join to 2 other tables.
I could use VBA to turn the local table into part of a pass-through query, with a large in() statement, or several where x='' ors but the local table may have 50000 entries in it. Is there a good or right way to pass this data in the query if I don't have write access to the server?
SELECT first.name,first.country, second.name, second.string FROM first LEFT OUTER JOIN second ON first.name = second.name WHERE first.date='2015/02/24'
This query means all record from second table and matching record from first table. Now my question is that on 24 Feb 2015 I have duplicate names in second table and I want distinct names from second table and then its matching values from first table. Now my query is showing all duplicate values from second table and its matching record from first table.
I need a bit of help with a join. I have 2 tables :
TradeSummary has fields : SymbolID, CurrentPrice, TotalValue
Trades has fields : SymbolID, TradeID, ExecutionTime, TradeValue
TradeSummary has one entry for each SymbolID, while Trades contains one or more entries per SymbolID
and what I want to retreive is :
For every item in TradeSummary get CurrentPrice, TotalValue from TradeSummary and also get TradeValue from Trades for the record for max(ExecutionTime) tables are joined on TradeSummary.SymbolID = Trades.SymbolID
Every attempt of mine so far returns multiple rows for each SymbolID - I want only one row per SymbolID
I have run into a problem that I am stuck on. I have 3 tables lets call them a,b, and c. What I want to do is left outer join a with b on a common value, then replace any null values in this result with a default value, and then left outer join table c on the previously joined table (on the columns that I just replaced certain values on).
I am new in SQL and i need do a query where I need sum values from 2 tables, when i do it the Sum values are not correct. this is my query

I have a report which totals sales by customer. Then table footer has a grand total of all customer sales. I would like to get a percent of each customer's sales against the total sales. How do I get the sum from the table footer to use in an individual customer row?
Hi all My query has some inner joins to some tables. And problem is when any ON clause get null as value, the correspondent record is not displayed. SELECTTableA.A, TableB.AFROM TableAINNER JOIN TableB ON TableA.A = TableB.A What I did try: SELECTTableA.A, TableB.AFROM TableAINNER JOIN TableB ON TableA.A = TableB.A OR TableA.A IS NULL (but It generates redundant values from TableB) I need to show all values even that value from Tablea is null Thank a lot for any help
If I try to run the code below, and even one of the values in the INNER JOIN statements is NULL, the DataReader ends up with zero rows. What I need is to see the results even if one or more of INNER JOIN statements has a NULL value. For example, if I want info on asset# 2104, and there's no value in the DriverID field, I need the rest of the data to display and just have the lblDriverName by blank. Is that possible?

I am having problems joining these two tables and returning the correct values. The issue is that i have a work order table and a revenue table. I only want to return the sum of the revenue when the revenue comes after the work order date. That is simple enough, but it gets tricky when there are multiple work orders for the same ID. for those instances, we only want the sum of the revenue if it shows up post the work order date and if it is before any other work order date. So ID 312187014 should only have the 9-5 revenue from below, not the 7/7 or 8/6 revenue because the 8/7 work order date is after those revenue dates and thus will not have any revenue tied to it because there is a 9/3 work order that ties to the 9/5 revenue. Additionally the 412100368 ID has a 7/7 work order that ties to the 7/26 revenue, and the 8/7 work order will tie to the 8/23 and 9/20 revenue
--===== Create the test table with
CREATE TABLE #workorder ( Id varchar(20), wo varchar(10), wodate datetime, amount float ) GO CREATE TABLE #revenue
I would like to compare values in the same table and get the single record with different values in the multiple columns.For table tab1, ID is my key column. If type1 is active (A) then i need to update X else blank on Code1 column and if type2 is active (A) then i need to update X else blank on code2 column. Both type1 and type2 comes from same table for same ID..Below is the example to understand my scenario clearly....
declare @tab1 table (ID varchar(20), dt date, status varchar(1), type varchar(10)) insert into @tab1 values ('55A', '2015-07-30', 'A', 'type1') insert into @tab1 values ('55A', '2015-07-30', 'C', 'type2') insert into @tab1 values ('55B', '2015-07-30', 'C', 'type1') insert into @tab1 values ('55B', '2015-07-30', 'A', 'type2')
I have a query which is returning a different result set when it is run against identical tables in 2 different environments.
The query is like:
Select F.LicenseeID, IsSpecialLicensee from FactTable F left join View_SpecialLicensee SL on F.LicenseeID = SL.LicenseeID
The Create Statement for the view is like
Create View [dbo].[View_SpecialLicensee] as Select LicenseeID, LicenseeName, IsSpecialLicensee = 1 from DimensionLicensee where LicenseeName like '%ibm%' or LicenseeName like '%cisco%' or LicenseeName like '%hp%'
In my test environment, I get the query result I expected: LicenseeID, IsSpecialLicensee 1 , 1 - (where LicenseeName = 'IBM') 2, null - (where LicenseeName = 'Juniper') 3, 1 - (where LicenseeName = 'Cisco') 4, null - (where LicenseeName = 'Microsoft') 5, null - (where LicenseeName = 'Oracle') 6, null - (where LicenseeName = 'Apple')
In my production environment, I get the following query result: 1 , 1 - (where LicenseeName = 'IBM') 2, 1 - (where LicenseeName = 'Juniper') 3, 1 - (where LicenseeName = 'Cisco') 4, 1 - (where LicenseeName = 'Microsoft') 5, 1 - (where LicenseeName = 'Oracle') 6, 1 - (where LicenseeName = 'Apple')
Ideas as to what changed gratefully received.
FYI the production environment which returned the 2nd dataset is SQL2000, I have got the result I expected in both SQL2000 and SQL2005 development environments.
Hi, I am using a SQL back end to dynamically populate an asp.net report/page. As the data I'm interrogating is created from a tree control, I'm having to use a recursive function to retrieve the data into a series of ID values. This all happens at the moment in a DataTable manipulated with c# code. So my ID values end up in this datatable. My problem is that I am then performing a crosstab query in SQL Server 2000 and these ID are required as part of that query. Should I create a temp table and join this into the query or should i feed in a series of ID values into a where clause? Any help gratefully appreciated. Thanks. John
I have a SQL database where I am attempting to perform a complicated query that I cannot seem to figure out. I am using SQL Server.
I have 4 tables (TableA, TableB, TableC, and TableD). TableA and TableB are guaranteed to have a relationship.
TableC and TableD are guaranteed to have a relationship.
The trick is, I need to link between TableA and TableC essentially using a LEFT JOIN. I need to retrieve all of the values from TableA regardless and the information from TableC and TableD if there is a link, if there isn't a link, then the values from TableC and TableD need to be empty strings.
Does anyone know how I can do this? I've been trying for the last 5 hours without any luck. I feel I'm close, but there is something I feel I'm overlooking.
in my table i ve the column of item code which contains '1000' ,'2000' ,'3000' series i jus wanna display the output of item codes '1000','2000'series and some of ('3000019','3000020','3000077','3000078').
i tried in my join query
these code left(itemcode,4) in ('1000','2000') or itemcode in ('3000019','3000020','3000077','3000078')
I have this INNER JOIN that is fine to show all possible combinations. But I need to show only rows that have one or more Null values in tbIntersect.
Should I use nested LEFT JOINT? How?
