How can we write a query to achieve this while keeping in mind:
- We do not want to do unnecessary record lookups and Updates
- We only update records that corresponds to new entries. For example, we should not touch the record for InvoiceID = 2 in the above example
I am performing analysis of linked servers across 2000-2008R2 and need to find/build a list of linked servers that are truly active. For the sake of the post let's define 'active' have executed a distributed query in the last 5 days.
I have been scanning the DMVs without much success. Perhaps I must look more closely at MSDTC?
The end result would be to cleanup 300+ linked servers across 40+ SQL Servers.
any useful SQL Queries that might be used to identify lists of potential duplicate records in a table?
For example I have Client Database that includes a table dbo.Clients. This table contains various columns which could be used to identify possible duplicate records, such as Surname | Forenames | DateOfBirth | NINumber | PostalCode etc. . The data contained in these columns is not always exactly the same due to differences caused by user data entry; so some records may have missing data from some of the columns and there could be spelling differences too. Like the following examples:
1 | Smith | John Raymond | NULL | NI990946B | SW12 8TQ 2 | Smith | John | 06/03/1967 | NULL | SW12 8TQ 3 | Smith | Jon Raymond | 06/03/1967 | NI 99 09 46 B | SW12 8TQ
The problem is that whilst it is easy for a human being to review these 3 entries and conclude that they are most likely the same Client entered in to the database 3 times; I cannot find a reliable way of identifying them using a SQL Query.
I've considered using some sort of concatenation to a new column, minus white space and then using a "WHERE column_name LIKE pattern" query, but so far I can't get anything to work well enough. Fuzzy Logic maybe?
the results would produce a grid something like this for the example above:
ID | Surname | Forenames | DuplicateID | DupSurname | DupForenames 1 | Smith | John Raymond | 2 | Smith | John 1 | Smith | John Raymond | 3 | Smith | Jon Raymond 9 | Brown | Peter David | 343 | Brown | Pete D next batch of duplicates etc etc . . . .
Hey Forum, Below is a solution for passing a previous value (Height) to the current record in a view using two related tables (Plant= ID PK and plantHeight = ID FK) However, I was wondering how I could also do the reverse, that is, pass a next value to the current record.
I am novice to intermediate writer of T-SQL. Here is my current Query:
SELECT [FISCALYEAR], [ACCTPERIOD], SUM([ACTIVITYDEBIT]) AS TrialBalanceDebit, [POSTINGTYPE] FROM [dbo].[TB_Lookup] WHERE [POSTINGTYPE]='Profit & Loss' GROUP BY [FISCALYEAR],[ACCTPERIOD], [POSTINGTYPE] ORDER BY acctperiod ASCand this is what is produces.
FISCALYEARACCTPERIODTrialBalanceDebitPOSTINGTYPE 2014 201401 282361372.13000 Profit & Loss 2014 201402 227246272.86000 Profit & Loss 2014 201403 315489534.33000 Profit & Loss 2014 201404 287423793.76150 Profit & Loss 2014 201405 256521290.76000 Profit & Loss 2014 201406 65582951.30000 Profit & Loss
Now I need a way to add another field that takes the TrialBalanceDebit from current ACCTPERIOD and adds it to the Previous ACCTPERIOD TrialBalanceDebit.
I have a query that will go into an ssis package (eventually). The package will run every night at 3am. I need to capture the last 24 hours of by using something like:
SELECT worktype, changedate, woclass where siteid = 'GTM' and woclass = 'WORKORDER' and istask = 0 [highlight=#ffff11]and changedate between '2015-01-13 03:00:00' and '2015-01-14 03:00:00'[/highlight]
I know I am not doing the between correctly to get the changedate between the last 24 hours. Is there a way to correct this so that I am only getting the change date that is between 3am today and 3am yesterday on any given day I happen to run this?
I've tried all sorts of code i.e. cross apply, running totals, etc. Cannot get this to work. I am trying to add a previous row value but only doing it for each group.
I would like to set the start time of the next row to be equal to the previous row time + duration. I know the start time of each group of 'Items' when the 'Sequence' number = 1. The last 'duration' value in the group would be ignored.
Hi every one I want to get the currently entered or updated record in the database table by using SQL Query or stored procedure. Thanx in advance Take care Bye
I am working on some payroll related code which currently has the following hard-coded CASE statement (I won't include the entire thing, it is lengthy):
AND b.TCDateTime BETWEEN '2013-01-01 0:00' and '2013-12-31 23:59'
I want to get rid of the hard coding, and have this use current year dates. So for 2014, it should reference rows where the TCDateTime is >='2014-01-01 0:00' AND <'2015-01-01 0:00'..I think the following would accomplish this, but would like confirmation that this is the 'best' way (and that it will work!)
SELECT CONVERT(DATETIME, CONVERT(CHAR(4), DATEPART(yyyy, GETDATE())) + '0101') AS curryrbegin --output should be yyyy-01-01 00:00:00.0 where yyyy is current year SELECT CONVERT(DATETIME, CONVERT(CHAR(4), DATEPART(yyyy + 1, GETDATE())) + '0101') AS nextyrbegin --output s/b nextyear-01-01-00:00:00.0
Then, change the CASE statement to read:
AND (b.TCDateTime >= curryrbegin AND < nextyrbegin)
I am working on a report and the data source is Teradata. now I have situation where I want to get order id details based on the current quarter and year I am posting this same data. For TD related queries I do not where to post.
I have to download the files from SFTP server, for which i am using WINSCP and i am able to successfully automate the process to download the files. But it is downloading all the files instead of only current day's files. Ihave searched for WINSCP documentation for time query parameter to pass to the get command. But its not working.
My source file name contains Datefield as "Filenameexample_150120_N001.txt".
Here 150120 mean Jan 20 2015.
Winscp has no functionality to query the files to parse using datefield. how to look for files which are from today's date.
Currently i am downloading files which contain *.* (meaning all files).
I have a table of magazine issues. The table are defined as below: issueID int Uncheckedname varchar(50) Uncheckedtitle varchar(100) Checkeddescription varchar(500) CheckedcrntIssue bit Checkedarchived bit CheckednavOrder int CheckeddateCreate datetime Checked And here is what I want. Is there a way when inserting/updating or on the table itself to make sure that there is only one record that is marked as the current issue? The way I have it here in my table, any records can have the current issue (crntIssue) field checked. I only want one crntIssue field checked regardless of how many records or issues are in the table. If there is no way to automatically have SQL Server to manage that then that means I must check all the records before hand before the update/insert query, correct?
Well, I really messed up. Instead of changing the name of a current company record in a table I changed ALL the company names in the table. Me.CustomerDataSource.SelectCommand = "UPDATE tbl_customers SET company = '" & companyTextBox.Text & "'" So, I need to insert a WHERE clause to fix this. My problem is that I've been searching everywhere for this simple command structure and cannot find anything that specifically addresses a simple way to reference the current record. I tried...Me.CustomerDataSource.SelectCommand = "UPDATE tbl_customers SET company = '" & companyTextBox.Text & "' WHERE recno = @recno" But I get the error: Exception Details: System.Data.SqlClient.SqlException: Must declare the scalar variable "@recno". Can anyone provide this simple query clause?
My current code returns account_number with multiple start_date regardless of the value is same or not. However, I would like to get only the account number when the value on start_date is different within same account_number.
select acct_number count(start_date) from table_A group by acct_number, start_date having(count(start_date) > 1)
CREATE TABLE #TEMP ( TYPE VARCHAR(10), SEQ INT, SUB_TYPE VARCHAR(10))
[Code] ....
Now for each type the seq is very important. Effectively by order of seq the subtype stays the same until another subtype changes it. So for TYPE1 100,110 and 150 are A. 170, 200,220 are B. 230 and 250 are C and so on.
However as you can see the data isnt actually stored in the row. I need a select statement that shows this data.
I have done this:
SELECT t1.*,t3.SUB_TYPE FROM #TEMP t1 CROSS APPLY (SELECT MAX(SEQ) SEQ FROM #TEMP AS t2 WHERE t1.SEQ >= t2.seq AND t2.SUB_TYPE <>'' AND t1.TYPE = t2.TYPE GROUP BY t2.TYPE) t2 INNER JOIN #TEMP t3 ON t3.TYPE = t1.TYPE AND t2.SEQ = t3.SEQ
And it seems to work. Is this the easiest way to do it or am i missing something?
I have a table full of items that have a "date_updated" field. I'd like this field to be set to GETDATE() whenever a record is updated. I've got this trigger:
CREATE trigger tr_cp_shiptos_u on dbo.cp_shiptos for update as update cp_shiptos set date_updated = GETDATE()
Problem is, of course, there's no WHERE clause..yet. I don't know how to refer to the record that was updated.... for example:
CREATE trigger tr_cp_shiptos_u on dbo.cp_shiptos for update as update cp_shiptos set date_updated = GETDATE() where shipto_id = @THIS_ID
I imagine there's some kind of builtin variable or something like that. How is this done?
Do anybody know how can I find or display to the current SQL server 2005 record number (eg. 10 of 1600) on a VB 2005 form label. The BindingNavigator on the form has been deleted. Thanks.
I am using MSSQL Server 2008R2 and I am interested in returning rows from a 'financial' table that fall within the current year (each row contains a 'Entered Date'). I am located in Australia so my financial year consists of all entries between the date 01/07/xx to the 30/06/yy.
Perhaps using the datediff() function, or other functions as required to achieve what I need?
,I am creating a database where each record is required to have a twin record in the database.These is a type a value and a type b value and both must be present for the record to be valid.
Customer_ID, Order_Type, Product_Code 54, a, 00345 54, b, 00356
Is this something that would have to be done programmatically, or is it possible to create a constraint of some sort to ensure this?
I have a table with score info for each group, and the table also contains historical data, I need to get the ranking for the current week and previous week, here is what I did and the result is apparently wrong:
select CurRank = row_number() OVER (ORDER BY cr.CurScore desc) , cr.group_name,cr.CurScore , lastWeek.PreRank, lastWeek.group_name,lastWeek.PreScore from (select group_name, Avg(case when datediff(day, asAtDate, getdate()) <= 7 then sumscore else 0 end) as CurScore
[Code] ....
The query consists two parts: from current week and previous week respectively. Each part returns correct result, the final merged result is wrong.
I need to write SP which will call from front End to populate dropdown, But in dropdown uppermost value should be frequently used.
For example, My SP Select CountryID,Country Columns where i am displaying Country in dropdown. Now first time it will sort by ascending, next time if user selects US then US should be top and rest things after that.
Now If user selects Canada 3 times then result should sort as Canada,US, and rest countries.
if again US Selects 7 times then result should display as US,Canada,........
In short need to sort depending used previously. i.e. most popular first and so on......
I am having table which is having 5 columns say A,B,C,D and E. There are chances to change in C,D,E columns. I want to identify if any change happened in the above column and show to user prev value + new value.
i.e. i want to prepare query by using calculated extra 6 column where i want to put change happned in C,D,E columns.
The situation is that we have resources (trucks) that perform shifts. Shifts consists of actions. A resource can perform multiple shifts.
For every resource we want to find the record that:
- Is 'younger' than the last realized action.
- Has actionkind pickup, deliver or clean
I have constructed a solution with CTE and row_number but I was curious if there would be other alternatives. The fact that I'm joining a CTE onto itself and subject the outcome to a partition makes me think there are sharper ways.
Note that the action id in the data below is also sorted but in practice this need not be the case. The sorting key is prevalent.
I have a client with a fairly simple table as illustrated in my sample code. Their interesting requirement is that the records would be listed horizontally, end-to-end as I hope you can visualize based on what I'm providing here. Two other characteristics/specs of note, 1) there could be as few as two records end-to-end in a row or as many as 100 and 2) of course the column headings would have to be unique.
create table #tmpEndToEnd ( ID int identity, ClientID char(10), Agency varchar(20), Clinician varchar(20), Goal varchar(50)
I am having tables with 12 columns as jan,feb,.......dec.
Now I want to calculate average salary for each record, but condition is that if any month salary is zero then that column also exclude from average calculation.
For example : if jan and feb column values are zero then i want to calculate (mar+apr+...+dec)/10.
I am simply inserting records in a table, But if record already present then i dont want add that record and display resultset as -1.If record is not present then i want to add that record and commit transaction. I am doing like below : below is sample, I am considering only two columns.
CREATE PROCEDURE [dbo].[Sproc__Save_Teacher_Details] -- Add the parameters for the stored procedure here @FacilitiDetailID int ,@SpecialityType varchar(50) AS BEGIN
[code]....
above code is working fine for new recordset but if record exists then it is giving two resultsets -1 and 1, but i want to display only -1.
1) TableA : Which contains 5 columns(Column1,..........Column5) 2)TableB : Which contains 10 columns(Column1,..........Column10)
TableB contains millions of data.Now I want select all 5 columns from tableA but combination of Column1,Column2,Column3 if present in tableB, then i want exclude that records.I am doing as below:
select * from TableA a join TableB b a.column1!=b.column1 and a.column2!=b.column2 and a.column3!=b.column3 )
But query is taking almost 5 minutes. Is there is another approach?
I have created the following SQL snippet that is a very simple mock-up illustrating the problem (I hope!) that I am facing:
-- create table if object_id('tempdb..#tmpdelnotes') is not null drop table #tmpdelnotes
create table #tmpdelnotes( DelNote int identity (1,1) , DelDate date not null, Item int not null, Customer int not null)
[code]...
What I need to retrieve is a unique list of item numbers with information about the latest (DelDate) delivery note. The "Clumsy workaround" works, but is not very pretty when doing multiple table joins. Is it really necessary to use a derived table for this kind of query? Window functions can only exist in the SELECT and ORDER BY clauses, which is understandable since the calculations take place (I would guess) after the aggregations in the HAVING clause.
