I have a table (tblA) that records the RecordID, UserID and
LastViewedDate (DateTime) of each record opened in tblB where RecordID
is the PK in tblB. I want to construct a query that groups all records
in tblA by RecordID, filters by UserID and keeps only the most recent
25 RecordIDs and deletes the rest.
This gets me a recordset of all RecordIDs filtered by UserID in tblA
but I can't figure out how to sort it by LastViewedDate DESC and to
eliminate those not in the Top25:
SELECT RecordID
FROM dbo.tblA
WHERE (UserID = 1234)
GROUP BY RecordID
I'm hoping someone can tell me how to construct a stored procedure thatdeletes all records in tblA not matching the PK in tblBThis gives me the recordset of all records in tblA with no matchingrecords in tblB (ID is the PK in tblB)SELECT a.IDFROM dbo.tblB bRIGHT OUTER JOIN dbo.tblA a ON b.ID = a.IDWHEREb.ID IS NULLthanks,lq

I'm trying to clean up a database design and I'm in a situation to where two tables need a FK but since it didn't exist before there are orphaned records.
Tables are:
Brokers and it's PK is BID
The 2nd table is Broker_Rates which also has a BID table.
I'm trying to figure out a t-sql statement that will parse through all the recrods in the Broker_Rates table and delete the record if there isn't a match for the BID record in the brokers table.
I know this isn't correct syntax but should hopefully clear up what I'm asking
I have a strange request that might not be possible based on the laws of relational databases but I thought I'd give it a try.
I have three tables which for simplicity I will call A, B and C. Table A contains my master records, Table B contains user details and the final table contains some extra data
In my initial search when joining A and B, I return 100 records. I then need to search in table C for these 100 records based on a criteria. the expected result should return all 100 rows for the ones that match and also the ones that do not match. The problem is that in Table C, not all the 100 IDs exist, so there will not be a corresponding record. Unfortunately, our users still want to see all 100 records in the output. Is this possible
As always any help or direction would be appreciated.
Hi, This is a where clause I am using in a search. WHERE (ADDRESS_STREET LIKE '%' + @Search + '%' ) I am trying to do a search which returns the most matching record. For example if I have a record with Denver as text . If I search for Denvr the spell error is intended , I will not get the result. How can I create a stored procedure to counter probable spelling errors and return matching results in a ranked order. Thanks
Init SC --- 89 Post NCOA --- 89 Post Supp --- 89 Revised Final State Counts --- 89 Revised Final State Counts --- 94 ***********************************************************************************************
Since "Revised Final State Counts" appears in both cycles 89 & 94. How can I query the table so that I only get that 1 record?
Hello I am new to SSIS and learning as I go. Any guidance to my questions would be appreciated.
I wrote a script that takes the current date and subtracts a number of days/months from this date. I then attempted to use an SQL Task as a select with a parameter using the calculated date from the script. I was not successful in doing this. While performing searches on the WEB with the hopes of finding a solution I came upon the following text in the Microsoft forum under EXECUTE SQL TASK.
When you use an OLE DB Connection Manager, you cannot use parameterized subqueries because the Execute SQL task cannot derive parameter information through the OLE DB provider. However, you can use an expression to concatenate the parameter values into the query string and to set the SqlStatementSource property of the task.
Having come upon this statement I moved on to putting together an OLE DB SOURCE with a Flat File Destination. The SQL that I wrote is:
SELECT BP_ID, INVC_NBR, INVC_DT, BUS_ADD_DT FROM DW.CUST_SALE_ADDR WHERE (BUS_ADD_DT = ?)
The flat file destination was mainly used to confirm the select.
Having confirmed my select, I changed the select in the OLE DB SOURCE as follows:
DELETE FROM DW.CUST_SALE_ADDR WHERE (BUS_ADD_DT = ?)
I also removed the Flat File Destination. Needless to say when I tried to run the package I did not get very far as a package validation error was encountered since there were no output columns.
Can you share how I should go about peforming the delete as described from the table based on a calculated date? And am I not understanding the comment regarding the SQL Statement and the use of parameters?
There is something I don't understand. When I use join
SELECT r.CHECK_NUMBER, i.orig_file from (AP_INVOICEDOCS i join AP_DETAIL_REG r on r.PAYABLE_ID= i.PAYABLE_ID)
I am getting 76 orig_file records
But when I do
SELECT r.CHECK_NUMBER, i.orig_file from (AP_INVOICEDOCS i right outer join AP_DETAIL_REG r on r.PAYABLE_ID= i.PAYABLE_ID)
I am showing only 8 records under i.orig_file column and I am not sure why. What I need is to get all the AP_INVOICEDOCS in the matching orig_file records.
How to return only non matching left join records. Currently I am doing a traffic management database to learn sql.
I am checking for all parishes with no associated drivers. Currently I only have 2 of such.
The regular left join
select parish.name, driver.fname from parish left join driver on driver.parish=parish.name
Returns the all the names of the parishes and the first name of the associated drive, followed by the matches, however the two parishes with no matches have null for the first name.
update wce_contact set blank = 'missing' where website in ('www.name1.co.uk','www.name2.co.uk','www.name3.co.uk')
I know this query will set 'blank' to missing when it matches the above websites. However if i wanted to set blank to 'missing' where mail1date is not null and mail2date is not null (keep going to mail18date not null) how exactly would i go about this?
I guess it would be a case of adding another bracket somewhere but im unsure?
I have a database with thousands of records that contain personal details of customers. Some of these records pertain to the same customer - however, they have been submitted by different people, so they differ slightly in detail.
I've been looking to see if any of the data mining tools provided by Business Intelligence Studio in SQL Server 2005 will enable me to achieve a high degree of accuracy in matching records that pertain to the same customer. From what I can see, these tools seem more suited to making general predictions based on large groupings rather than the kind of precise prediction I am looking for.
So I'd appreciate it if anyone could tell me if there is any way I could use Business Intelligence Studio to match these 'duplicate' records together, or whether I will have to create a more SQL-based solution which attempts to match the customer records using SELECT statements and making assumptions about the data.
Problem: I am working on a price comparison system which matches the best prices for a purchase (or an order) from exisiting purchase data. The order is stored in multiple tables including order details (stores major items purchased: e.g., PC) and order sub-details (optional items purchased with the major items: e.g., speakers, backup device, webcam etc.). There could be a number of major items in an order and each major item could have multiple related sub items. The other variables that affect the price include trade-ins if any, sales going on at the time of order, number of units etc.
Now, for any new configuration (major items/related sub items), the system should be able to return a list of previous purchases made with similar configurations, and similar variables (quatities, trade-ins etc). Even if the same model is not present, similar pcs by the same vendor should be considered. etc etc.
Questions: Is this possible using Data mining? If yes, which algorithm is recommended?
Also, can I assign/modify any kind of weights to certain variables (if same model: .6 ; if same model not available but pcs made by same manufacturer available: .3 ; by other manufacturers: .1)?
Hi Gurus!!! I have two tables tabl_a and tbl_b now tbl_a has some records which are not in tbl_b. I want to update tbl_b with records in tbl_a eg: tbl_a tbl_b a a b b c c d d x y z Now I want to update tbl_b with records 'x', 'y', 'z'. I want to keep the matching record just untouched. Something similar. How can I do that??? Thanks in advance!!!
I am using Master Data Service for couple of months now. I can load, update, merge and soft delete data in MDS. Occasionally we even have to hard delete data from MDS. If we keep on soft deleting records in a MDS table eventually there will be huge number of soft deleted records. Is there an easy way to hard delete all the soft deleted records from all MDS tables in a specific Model.
I have been trying to solve the locking problem from past couple of days. Please help mee!!
Scenario: -------------- I have a SSIS package in which 2 data flow tasks. 1st data flow task deletes records from a 5 tables and the 2nd data flow task should insert records into 1 of the five tables after the success of 1st data flow task. This scenario runs in Transacation.
The above scenrio in the 2nd data flow task hangs in runtime. It does not complete. with sp_who2 command i could see that there is an intent share lock(LK_M_IS) on the table and the status is SUSPENDED.
I dont know how to come out of this locking. Please help.
I am doing some analysis on our customer base and their payment profiles. I have generated two profile strings, one for whether the balance of an account has gone up or down and one for the size of the balance in relation to the normal invoice amount for the customer. So (for example) the balance movement string will look like this:
UUUDUUUDUUUD-D00 Where U = Up, D = Down, - = no change and 0 = no change and no balance
I want to analyse these strings in two ways. The first is that I want to find customers with a similar pattern: in the example below the first and last patterns are the same, just one out of sync but should be considered the same
Movement Multiple CountRecords UUUDUUUDUUUD1230123012301175 ------------0000000000001163 UDUUUDUUUDUU3012301230121082
The second type of analysis is to find customers whose pattern has changed: in the examples above the patterns are repeated and therefore 'normal' in the records below the patterns have changed in that the first part does not match the second part.
Movement Multiple CountRecords UUDUUUDUUUUU-----------07 UDUUUDUUUUUU------------7
good way to approach this without either a cursor or a hidden REBAR. The challenge as I see it is that I have to interrogate every string to find out if there is a repeating pattern and if so where it starts and how long it is (heuristic because some strings will start with a repeating pattern and then the pattern may change or deteriorate) and then compare the string for N groups of repeating characters to see if and when it changes and I can't think of an efficient method to do this in SQL because it is not a set based operation.
Folks,Using NorthWind as Example: Parent Table derived from: Categories. I added a new Column E-Mail and Selecting rows where Category Id <=3. Here is my Data.
Category ID Category Name Category E-mail
1 Beverages Beverages.com
2 Condiments Condiments.com
3 Confections Child Table derived from: Products. I am Selecting rows where Category Id <=3. Here is my Sample Data.
Category ID Product Name Quantity Per Unit
1 Chang 24 - 12 oz bottles
1 Côte de Blaye 12 - 75 cl bottles
1 Ipoh Coffee 16 - 500 g tins
1 Outback Lager 24 - 355 ml bottles
2 Aniseed Syrup 12 - 550 ml bottles
2 Chef Anton's Gumbo Mix 36 boxes
2 Louisiana Hot Spiced Okra 24 - 8 oz jars
2 Northwoods Cranberry Sauce 12 - 12 oz jars
3 Chocolade 10 pkgs.
3 Gumbär Gummibärchen 100 - 250 g bags
3 Maxilaku 24 - 50 g pkgs.
3 Scottish Longbreads 10 boxes x 8 pieces
3 Sir Rodney's Scones 24 pkgs. x 4 pieces
3 Tarte au sucre 48 piesI would like to read 1st Category Id, Category E-Mail from Categories Table (ie. Category Id = 1), find that in Products Table. If match, extract matching records for that Category from Both Tables (Categories.CategoryID, Products.ProductName, Products.QuantityPerUnit) and e-mail them based on E-Mail Address from Parent (Categories ) Table. If no E-Mail Address is listed, do not create output file. In this instance Category Id = 3.Basically I want to select 1st record from Parent Table (Here is Category) and search for all matching Products in Products Table. And Create an E-mail and sending just those matching records. Repeat the same process for remaining rows from Categories Table. I am expecting my E-Mail Output like this: For Category Id: 1
2 Northwoods Cranberry Sauce 12 - 12 oz jarsI am not extracting the Data for any user Interface (ie. Grid View/Form View Etc). I will just create a Command Button in an ASP.NET 2.0 form to extract Data. My Tables are in SQL 2005. I was thinking to read the Category records in a Data Reader and within the While Loop, call a SP to retrieve the matching records from Products Table. If matching records found, call System SP_Mail to send the E-mail. The drawback with that for every category records (Within While Loop) I need to call my SP to get Products Data. Will be OVERKILL? Ideally I would like extract my records with one call to a SP. Is there any way I can run a while loop inside the SP and extract Child Data based on Parent Record? Any Help or sample URL, Tutorial Page will be appreciated. Thanks
I have an Excel file which contains some data. I want to load that into a SQL server Table. Here are my conditions :
1. If the table doesn't have any matching records from the Excel file, then my DFT should load the data from that Excel to the Dest Table.
2. If the table has even one or more matching records, then the DFT should not process at all, instead I should send an email to the business stating that there are some matching records and hence the package is not process...ed.
P.S. If i use Lookup, I have two matching and non-matching output. which will process the non matching records into the table and matching can be redirected to any flat/Excel file. But i don't want to do this. I just want to lookup the Sql Server table and excel.
It'll be good if there is an additional option in the Lookup "Fail component on matching records".
create table a (id int, name varchar(10)); create table b(id int, sal int); insert into a values(1,'John'),(1,'ken'),(2,'paul'); insert into b values(1,400),(1,500);
select * from a cross apply( select max(sal) as sal from b where b.id = a.id)b;
Below is the result for the same:
idname sal 1John500 1ken500 2paulNULL
Now I'm not sure why the record with ID 2 is coming using CROSS APPLY, shouldn't it be avoided in case of CROSS APPLY and only displayed when using OUTER APPLY.
One thing that I noticed was that if you remove the Aggregate function MAX then the record with ID 2 is not shown in the output. I'm running this query on SQL Server 2012.
i have one query: SELECT MAX(salesid) AS salesid, max(salestitle) as salestitle FROM saleshistory s where list = 'sales' GROUP BY DATEADD(dd, DATEDIFF(dd, 0, salesdate), 0) order by salestitle
i m getting more than 1000 rows.. in output some of them are :
when i m doing like: SELECT MAX(salesid) AS salesid, max(salestitle) as salestitle FROM saleshistory s where list = 'sales' GROUP BY substring([salestitle],1,charindex(' ',[salestitle])-1)
i m getting an error Msg 536, Level 16, State 3, Line 1 Invalid length parameter passed to the substring function.

Hello, its hard to explain, i have a table like this: --userpage_visitors-- id bigint owner nvarchar(20) visitor nvarchar(20) created datetime Then i have some code like this: (@Visitor is send to the stored proc)DECLARE @lastuser nvarchar(20)SELECT TOP 1 @lastuser = visitor FROM userpage_visitors WHERE (owner = @UserName) ORDER BY created DESCIF (@lastuser <> @Visitor)BEGININSERT INTO userpage_visitors (owner, visitor, created) VALUES (@UserName, @Visitor, @Created)-- delete hereEND Now after i have inserted the new visitor into the table, i need to clean the table... so each user should have maximum of 30 visitors, so if the user i inserted above is the 31st user then i need to delete the first user, so i always have 30 fresch visitors,, if they have less then 30 visitors then nothing should happen. The question is, how can i get the 31th post? in mysql you can say that you want post 30, 31, but in mssql you only have the TOP to select limited posts, any ideas? Patrick
