SQL Server Max Record, Multiple Table Join Problems
Jul 20, 2005
Thanks in advance for you help.
SQL Server 2000
I have a complex join, but a simple example will do the trick so...
table1 (placement records, possibly many per case,highest ID being
most recent)
----------
placementID(pk) * CaseID(fk) * OrganizationID(fk) * Name * Number
table2 (Organizations Table, Many Placements can be at 1 organization)
----------
OrganizationID(pk) * OrgName * OrgType
table 3(Case Table, each Case can have many placements)
----------
CaseID(pk) * StaffName * CreationDate
now my query...
SELECT t1.placementID,t1.caseID,t2.OrgName
FROM table1 as t1
INNER JOIN table2 as t2 on t2.OrganizationID = t1.OrganizationID
WHERE exists (select distinct max(placementID),CaseID
from t1 group by caseID)
GROUP BY t2.OrgName,t1.PlacementID,t1.CaseID
my results
-------------
placementID CaseID OrgName
1 1 oneOrg
2 1 two org
3 1 three org
4 2 another org
5 3 yet another org
my desired results
------------------
PlacementID CaseID OrgName
3 1 three org
4 2 another org
5 3 yet another org
as you can see i get all records, but what i want is to see only the
last placementID for each case so i dont want duplicate caseID but I
do need the orgName, and yes the query works correctly without the org
name but as soon as i add orgName to the select statement I get
duplicate CaseID's, How do i eliminate duplicate CaseID's and get only
the MAX(placementID) for each Case and the OrgName
please advise, getting desperate.
thanks again so much for the help
I have a table of "applicants" with unique applicant id and another table "reviews" with reviews which has unique id and Emplid and contains general program name like Math and then may contain 3 addition rows for specific program like Calculus, algebra, geometry etc.
There may or may not be a record for each applicant id in table reviews or there can be 1 or more than one record in reviews based on level of review( General or Specific).
All the general reviews has “Math” as Program_code but if there are more reviews, they can have Program_code like “Cal” , “Abr”, “Geo”
I want to join the tables so I can get all the records from both the tables where Program_code in reviews table is “Math” only.
That is I want to join the table and get all the records from reviews table where the program_code is “Math” only How can I do that?
I have a table with a large number of records that I need to delete, before attempt to perform the delete I also archived the records to another table.
So I need to delete all of these selected records stored in the archive table from the main table. I can now reference all the records that qualify for the delete in the main table by performing a join on the archive table like so:
select * from my_main_table a join my_archive_table b on a.distinct_id=b.distinct_id and a.surrogate_key=b.surrogate_key and a.identifier=b.indentifier
So all the records check out to be the ones I'd like to perform a delete on but I just can't figure out how to perform a delete of the records with little or no change to the existing query.
Obviously something like this won't work:
delete from my_main_table a join my_archive_table b on a.distinct_id=b.distinct_id and a.surrogate_key=b.surrogate_key and a.identifier=b.indentifier
Though it would be nice if it did.:D
So my question is how would I use the existing query with some modification to delete only the records that this query returns. I've tried selection of records in the main table based on the existing records in the archive table but it can return a higher number of records than what I know is expected. I actually need the join specified to be in place to do it.
i have below queries each select is fetching records at one level. Is there a way i can write single query to get to nth level (recursion) instead joining same table 10 times (i don't know in some cases there is may be next level) I stopped at 10th level now. In below example i gave only two levels.
SELECT Distinct a.Col1 AS EmpID, a.Col1 AS EmpID, a.Col2 AS Emp_guid, a.Col2 AS Emp_guid, case
Table A brings one record but table B brings two records for record in table A.
What I need is join both tables but I must bring (always) the max created record from table B if there are more than one record for the one in table A. Is this clear?
I dont want to use GROUP BY beacuse it is a very big query with lot of tables and it will be a mess.
I will give an example: TABLE A
ID NAME 1 PETER
TABLE B
ID_TABLEA CREATED BROTHER 1 1-1-08 JOHN 1 2-1-08 PATRICK
If I join both tables I will have two records. What I need is to have the max created record from table B even if one or more records are joined. I only need one match from table B for each record of table A. Any suggestion? Thanks in advance.
I have two table and there are releationsheep between them. Topic: topicId, topicName, topicDate Reply: replyId,topicId,replyName,replyDate I want to insert two table at the same time. Topic: 1,example,10/21/2007 Reply:1,1,example, 10/21/2007
It's come up more than once for me, where I need to DECLARE and SET several SQL variables in a Stored Procedure where many of these values come from the same table record - what is the best method for doing this, where I don't have to resort to making a separate query for each value. Currently I'll do something like this: DECLARE @var1 intSET @var1 = (SELECT TOP 1 field1 FROM table1 WHERE recordkey = @somekey)DECLARE @var2 nvarchar(20)SET @var2 = (SELECT TOP 1 field2 FROM table1 WHERE recordkey = @somekey) Of course, I'd rather just have to query "table1" just once to assign my variables. What obvious bit of T-SQL am I missing? Thank you in advance.
The code is the name of the test and the result is just that. Not all patients will have the same set of results. What I'd now like to do is pull out a CSV file of all results from 2013 including where the result is null. The format I am looking for is along the following lines:
Sex, Age, AKIN2, AKIN7, RIFLE,
The AKIN2, AKIN7 and RIFLE are the codes in the result table. I have tried OUTER JOINS but it seems to only pull out those records that exist (example below). I need to specify the result codes I am interested in otherwise the output could be enormous but this then does not pull out null values (a NULL value is an important as an actual value).
SELECT Samples.Patient_ID AS ID, Samples.LabNo As LabNo, Patients.Sex As Sex, DATEDIFF(year, Patients.DoB, Samples.Sampled) AS Age, Samples.Source as Source,
Ok, this is what I am trying to do:, 1) I am trying to get the number of employees that has completed all their online training within 10 days of hire 2) All the employees that are has no exception(no pre-service training) and has completed their checklist within 10 days 3) all the exception(pre-service) employees that has completed their training within 70 days.
I have these tables, hipaa2006, hipaa101, hipaa201_inputs, domesticviolence, securityawareness, securityawareness2006, civilrights_input, and people_first_data. People_first_data contains all the employees we have in our database, it has empl_pfid col, but does not have last_modified col which all the other tables has.
I have this queries:
1) select distinct(count(empl_pfid)) from people_first_data left outer join tbl_domesticviolence on people_first_data.empl_pfid = tbl_domesticviolence.employee_pfid left outer join tbl_hipaa101 on people_first_data.empl_pfid=tbl_hipaa101.employee_pfid left outer join tbl_hipaa201_input on people_first_data.empl_pfid= tbl_hipaa201_input.employee_pfid left outer join tbl_hipaa2006 on people_first_data.empl_pfid=tbl_hipaa2006.employee_pfid left outer join tbl_securityawareness on people_first_data.empl_pfid=tbl_securityawareness.employee_pfid left outer join tbl_securityawareness2006 on people_first_data.empl_pfid= tbl_securityawareness2006.employee_pfid where people_first_data.empl_pfid = '639846' and tbl_domesticviolence.last_modified is not null and tbl_hipaa101.last_modified is not null and tbl_hipaa201_input.last_modified is not null and tbl_hipaa2006.last_modified is not null and tbl_securityawareness.last_modified is not null and tbl_securityawareness2006.last_modified is not null
2) ( I tried union, but i only wanted one number) select count(last_modified) as date1 from tbl_hipaa2006 union select count(last_modified) as date2 from tbl_hipaa101
Now I want the records having flag2=1 only.. I.e ID=3 has flag2=1 where as ID = 1 and 2 has flag1 and flag3 =1 along with flag2=1. I don't want ID=1 and 2.
I can't make ID unique or primary. I tried with case when statements but it I am somehow missing the basic logic.
Hi there. I haven't been able to figure out how to join a table on column on multiple table names. Here's the situation:
I have a table "tblJob" with a key of jobID. Now for every jobID, the program creates a new table that keeps track of the stock before the jobId was processed and after it was processed to give accurate stock levels and show the difference in stock levels. So, a jobID of 355 would be related to the table: "tblPreStock_335" and "tblPostStock_335". These 2 tables have all the materials in stock and the quantity. Therefore they show how much material was used. I need to figure out the difference in the material in the stock before and after the processing.
That means that I have to get a stockID, get the associated pre and post tables, and then display the difference of ALL the materials in the pre and post tables.
Could someone help me get started on the right path? Even a link to similiar problem that I haven't found would be nice.
What is the best way to use a left join in a SQL statement with multiple tables (more than 2)? I have a query that uses 7 tables, where most of the joins are inner joins, except for one, which needs to be a left join. The current SQL statement looks something like this:
FROM [table1],[table2],[table3],[table4],[table5],[table6],[table7] WHERE [table4].[field2]=[table1.field2]{this is an inner join} [table4].[field2]=[table2.field2]{this is an inner join} [table4].[field2]=[table3.field2]{this is an inner join} [table4].[field2]=[table5.field2]{this is an inner join} [table5].[field3]=[table6.field2]{this is an inner join} [table5].[field4]=[table7.field2]{this is needs to be a left join}
As it stands now, the last line in the WHERE clause is an INNER JOIN and limits the number of rows in my result. I need to select rows from [table7].[field2] whether or not a matching record exists in [table5].[field4]. The other INNER JOINS in the SQL statement must have matching records. Please advise.
Hi,I'm am looking for a little help. I need to create a SQL view whichjoins a few tables, and I need to return an average for a particularcolumn where a second duplicate ID exists...Heres an example of how the results could be returned...ID | Name | Order No. | Value---+------+-----------+---------5 | test | 1234 | 35 | test2| 1234 | 45 | test3| 1234 | 35 | void | 1235 | 55 | void2| 1235 | 65 | void3| 1235 | 55 | void4| 1235 | 7ID is my main join which joins the tablesName is a unique nameOrder No is the same for the different names, I only need to return onerow with this order no, and the first name (the rest are irrelevant)Value is the field which I wish to return as an average of all 3, 4 orhowever many rows is returned and share the same order no. This iswhere I get totally lost as I am pretty new to SQL. Can anyone provideany help on how I would go about limiting this query to the uniqueorder no's and returning the average of the value field, and I can takeit from there with my own tables.Thanks for your helpstr8
I have a criteria where i want to join table 1 with table 2 , table 1 consists of products which were given to salesman to sell and table 2 has the sales data which salesman has sold out. Now i want to know left over products of each sales with join .Below is my data, here is what i am trying to do, but it return only salesman 1 data.
CREATE TABLE Salesman_Product ( SalesManID int, ProductID int ) INSERT INTO Salesman_Product (SalesManID,ProductID) Values (1,1),(1,2),(1,3),(1,4) INSERT INTO Salesman_Product (SalesManID,ProductID) Values (2,1),(2,2),(2,3),(2,4)
I want to use multiple datasets in a table and wants to do the full outer join on the two datasets in the same table. For example, my two datasets are:
I want to display a ssrs table like: Both the datasets are coming from different sources. So I cannot integrate them at sql query level.
I'm inserting from TempAccrual to VacationAccrual . It works nicely, however if I run this script again it will insert the same values again in VacationAccrual. How do I block that? IF there is a small change in one of the column in TempAccrual then allow insert. Here is my query
INSERT INTO vacationaccrual (empno, accrued_vacation, accrued_sick_effective_date, accrued_sick, import_date)
OrderID ControlName 1 Row1COlumn1 (It Means Pant in Red Color is selected by user(relation with Child2 Table)) 1 Row3Column1 (It Means Gown in Blue Color is selected by user(relation with Child2 Table)) 1 Row4Column3 (It Means T Shirt in White Color is selected by user(relation with Child2 Table)) 2 Row1Column2 (It Means Tie in Green Color is selected by user(relation with Child2 Table)) 2 Row3Column1 (It Means Bow in Red Color is selected by user(relation with Child2 Table))
Child2 Table
PackageID Product Color1 Color2 Color3 1 Pant Red Green Blue 1 Shirt Blue Pink Purple 1 Gown Blue Black Yellow 1 T Shirt Red Green White 2 Tie Red Green White 2 Socks Red Green White 2 Bow Red Green White
We want to have result like
OrderID PackageID CustomerName Pant Gown T Shirt Tie Bow
1 1 ABC Red Blue White x x Blue 2 2 Bcd x x x Green Red
I have tried
;with mycte as ( select ms.OrderID,ms.PackageID ,ms.CustomerName , Replace(stuff([ControlName], charindex('Column',ControlName),len(ControlName),''),'Row','') rowNum ,Replace(stuff([ControlName], 1, charindex('Column',ControlName)-1 ,''),'Column','') columnNum From child1 c inner join MasterTable ms on c.Orderid=ms.orderid)
[code]....
it works if we have a product in one color only. like if we have pant in red and blue then its showing just first record
How can we insert multiple records in a OLEDB destination table for each entry from the source table. To be more clear, for every record from source we need to insert some 'n' number of records into the destination table. this 'n' changes depending on the record. how is this achieved.
I came across this structure today and haven't seen it before:
SELECT blablabla FROM T1 FULL OUTER JOIN T2 ON T1.Col1 = T2.Col1 AND T1.Col2 = T2.Col2 ON T3.Col1 = T1.Col1 AND T3.Col2 = T1.Col2 ON T4.Col1 = T1.Col1 AND T4.Col2 = T1.Col2
I have 2 tables People and Scores. A person might have 1-5 scores (unknown at time of Query). I would like to query the two tables into a results table and if person does not have a record the score will be zero. Scores also have a test number so you know which score it is. I can get it done with Stored Proc but I have to use Temp tables and then put the temp tables together.
People Name ID Tom5 Dick2 Harry3 Larry4 Curly1 Scores PrimaryKeyPeopleIDScoreTestNumber 12801
I have a question about combining multiple records with same ID but different values between records on different fields into a single record with all values combined for all fields. Example: Multiple records with the same record ID:
I am trying to figure out how to use the select maximum command in SQL Server 2005. I have already created a database and I have it populate it with multiple fields and multiple records. I Would like to create a new column or field which contains the maximum value from four of the fields. I have already created a column and I am trying to figure out how to use a command or SQL statement which is entered into the computed equation or formula in the properties for this field/column.
Any help you can provide will be greatly appreciated!
Hi... I was hoping if someone could share me some thoughts with the issue that I am having at the moment.
Problem: When I run the package in my local machine and update local SS DB/table - new records writes OK in the table. BUT when I changed my destination meaning write record into another physical SS DB/table there is no INSERT data occurs. AND SO when I move/copy over that same package into another server (e.g. server that do not write record earlier) and run it locally IT WORKS fine too.
What I am trying to do is very simple - Add new records in a SS table using SSIS . I only care for new rows and not even changed rows. Here is my logic - 1. Create Ole DB source to RemoteSERVER - using SELECT stmt 2. I have LoopUp component that will look for NEW records - Directs all rows that don't find match and redirect rows (error output). 3. Since I don't care for any rows that is matched in my lookup - I do nothing or I trash the rows 4. I send the error rows (NEW rows) into OleDB destination
RESULTS when I run the package locally and destination table is also local - WORKS FINE; But when I run the package locally and destination table is in another Sserver (remote) - now rows is written.
The package is run thru BIDS manually so there is no sucurity restrictions attached to it.
I am not sure what I am missing. And I do not see error in my package either. It is not failing.
I would like to find out how to capture record count for a table in oracle using SSIS and then writing that value in a SQL Server table.
I understand that I can use a variable to accomplish this task. Well first issue I run into is that what import statement do I need to use in the design script section of Script Task. I see that in many examples following statement is used for SQL Server databases:
Imports System.Data.SqlClient
Which Import statement I need to use to for Oracle database. I am using a OLE DB Connection.
Previously same records exists in table having primary key and table having foreign key . we have faced 7 records were lost from primary key table but same record exists in foreign key table.
I have table 'stores' that has 3 columns (storeid, article, doc), I have a second table 'allstores' that has 3 columns(storeid(always 'ALL'), article, doc). The stores table's storeid column will have a stores id, then will have multiple articles, and docs. The 'allstores' table will have 'all' in the store for every article and doc combination. This table is like the master lookup table for all possible article and doc combinations. The 'stores' table will have the actual article and doc per storeid.
What I am wanting to pull is all article, doc combinations that exist in the 'allstores' table, but do not exist in the 'stores' table, per storeid. So if the article/doc combination exists in the 'allstores' table and in the 'stores' table for storeid of 50 does not use that combination, but store 51 does, I want the output of storeid 50, and what combination does not exist for that storeid. I will try this example:
'allstores' 'Stores' storeid doc article storeid doc article ALL 0010 001 101 0010 001 ALL 0010 002 101 0010 002 ALL 0011 001 102 0011 002 ALL 0011 002
So I want the query to pull the one from 'allstores' that does not exist in 'stores' which in this case would the 3rd record "ALL 0011 001".
Hello, I am in the progress of designing a new section of my database and was thinking of creating a hole new database instead of just creating tables inside the database. My question is can you JOIN multiple tables in an SQL Statement from multiple databases. Ie, In the Management program I have a database called 'Convention' and another one called 'Services', inside the two databases there are many tables. Can I link say tblRegister from Convention to tblUser in Services? Thanks
Hi I have a table with a user column and other columns. User column id the primary key.
I want to create a copy of the record where the user="user1" and insert that copy in the same table in a new created record. But I want the new record to have a value of "user2" in the user column instead of "user1" since it's a primary key
I want to get some combined data from both tables, so right now I am joining them at the SessionStartTime column, which is a primary key in the first and a foreign key in the second table, something like this:
Code: SELECT DlIndexTable.SessionStartTime, DlTextDataTable.Channel01data FROM DlIndexTable LEFT JOIN DlTextDataTable ON DlIndexTable.SessionStartTime = DlTextDataTable.SessionStartTime WHERE DlIndexTable.SessionStartTime BETWEEN '2006-10-13 16:40:08.790' AND '2012-03-01 17:54:30.930' ORDER BY DlIndexTable.SessionStartTime, DlTextDataTable.ChTimestamp
The trouble is that this query, exactly as requested, gives me all the entries from the second table matching the first, while I really would like to pick just one row (preferably, the first chronologically - by ChTimestamp) so that the first column (SessionStartTime) has distinct entries in the resulting table. What would be the simplest way of doing that? Performance is not a big priority over simplicity since the first table could have only a few hundred rows (maybe a couple of thousand), while the second will be real tiny.
Is that possible to restrict inserting the record if record already exist in the table.
Scenario: query should be
We are inserting a bulk information of data, it should not insert the row if it already exist in the table. excluding that it should insert the other rows.
Hi All,I have a table in SQL Server 2000 that contains several million memberids. Some of these member ids are duplicated in the table, and eachrecord is tagged with a 1 or a 2 in [recsrc] to indicate where theycame from.I want to remove all member ids records from the table that have arecsrc of 1 where the same member id also exists in the table with arecsrc of 2.So, if the member id has a recsrc of 1, and no other record exists inthe table with the same member id and a recsrc of 2, I want it leftuntouched.So, in a theortetical dataset of member id and recsrc:0001, 10002, 20001, 20003, 10004, 2I am looking to only delete the first record, because it has a recsrcof 1 and there is another record in the table with the same member idand a recsrc of 2.I'd very much appreciate it if someone could help me achieve this!Much warmth,Murray
