How To Delete Existing Data Based On Where Clause Condition
Feb 18, 2014
I have written a merge Statement where i am facing trouble to delete the data basing on Where Clause Condition.
1) Case 1 : For example i have inserted Data from Source to Target based on Date Key Condition.Take an Instance 10 Records Inserted.
2) Case 2 : For example some changes in the records and it has been updated through the Merge Statement .
3) Case 3 : For the Same Date key based on Conditions now three records has came and need to be inserted and rest should be deleted for that Date Key.
How i need to proceed on this before 10 records are not getting deleted and new records adding for that one
My Example Code :
MERGE INTO TargetTable AS Target
USING (
SELECT DISTINCT Col1,
Col2
FROM Table1 AS cga
)
ON dad.AnchorDate = CASE
For UserA : - For problemID 1 -> submitted three times -> rejected for first two submission and accepted on third submission. - For problemID 2 -> submitted one time -> accepted on first submission
For UserB : - For problemID 1 -> submitted two times -> rejected for first submission and accepted on second submission. - For problemID 2 -> submitted one time -> accepted on first submission
Now I would like to process the table and want to get the following result :
Explanation : - For each rejected submission, a -2 point penalty. - UserA have submitted probelmID 1 - > score of problemID 1 is 10. - > first two times rejectd - > third time accepted. -> score = 10 - 4 = 6 - UserA have submitted problemID 2 - > score of problemID 2 is 30 - > first time accepted. No penalty will be counted - > score = 30
I want to change Set clause of Update Statement dynamically based on some condition.
Basically i have 2 Update statments having same FROM clause and same JOIN clause.
Only diff is SET clause and 1 Where condition.
So i am trying to combine 2 Update statements into 1 and trying to avoid visit to same table twice.
Update t Set CASE **WHEN Isnull(td.IsPosted, 0) = 0 THEN t.AODYD = td.ODYD** *ELSE t.DAODYD = td.ODYD* END From #ReportData As t Join @CIR AS tmp On t.RowId = tmp.Max_RowId
I have the following scenario : CustomerDetail customerid customername status app_no
[status = 0 means customer virtually deleted]
CustomerArchive archiveno [autoincrement] customerid customername status
At the end of the month, I have to physically delete customers. I have written two stored procs:
proc1 create proc spoc_startdeletion as declare @app_no int select @app_no = (select app_no from customerdetail where status=0) EXEC spoc_insertcustomerarchive @app_no -- After transferrin, physically delete delete from customerdetail where status=0
proc2 create proc spoc_insertcustomerarchive @app_no int as insert into customerarchive(customerid,customername,status) select customerid,customername,status from customerdetail where app_no = @app_no
It works fine if there is only one row with status=0, however the problem is that when there are multiple rows in customerdetail with status=0, it returns 'Subquery returned more than one value'
How can i transfer multiple rows one by one from the customerdetail to customerarchive and then delete the rows once they are transferred.
I have a source table with App_Id, App_Type , Tier_Type, Date_Id as columns. I have a destination table with Date_Id, Total_App_Count, Booked_App_Type_Count, Approved_App_Type_Count columns.
I need to count the Total number of records , count of records with App_Type = "Booked" and count of records with App_Type = "Approved" and populate in my destination table.
What all the steps i need to create in SSIS to get this results ?
My current report has around 40 subreports corresponding to tests executed by the user. There is a different sub report for each of the tests executed. I first developed the report by just putting the subreports directly on the main report. The problem is if some of my tests are not executed by the user I would like the subreports to not appear in the report.
I have tried doing this two different ways. First I tried creating a table and attaching that table to a dataset that I created that returns all the tests that were executed by the user. I then set up a filter that specified that the name for a specific subreport had to equal the test name. I then dropped the sub report for that particular test into the table. The idea is there would only be one row when data is available and no rows when no data is available so the subreport would not appear. When the data is available the subreport appears great. When it is not available and there is no item in the dataset for that test I get an error from SQL that states there was an internal reporting error and to check the SQL server log for more information. I know my table is set up correctly because when I replace the subreport with text the text will appear only if data is available for that test and the text does not appear if no data is available. I get no errors until I add the subreport and remove the data from the database so the filter does not return any items. Is there a reason why I would be getting this error? I am still pretty green using reporting services so I do not even understand how to get the log from the server to determine why this error is occuring.
Secondly I have tried to use an expression to hide the subreport using the visibility tab for the report. I was able to get this to work by creating a dataset that returns 1 if a specific test has been executed and no rows if not. I then created an expression that would return true if the dataset returned 1. This worked okay in hiding my subreport but I would then have to create 40 datasets, one for each test. Is there anyway to write an expression that would return true if a dataset contained a row with a specific test name? I have not been able to figure this out.
Can someone either help me fix the problem I am having with the table approach or write an expression that would work in the visibility setting for each sub report that did not require 40 datasets? Or is there another approach that I am not even thinking of that might work?
i've been looking at moving one of our processed from excel (+vba) into t-sql to make life easier but am stuck.
We have lots of tasks that are assigned to work groups which we want to distribute evenly across the work groups. This is a simple task for ntile.. However when these tasks are no longer required they are removed which leaves the groups uneven. When new tasks are added we want to still try to keep these groups balanced.
Create table Jobs(jobid int identity(1,1), name varchar(100),Groupid int)
--Existing tasks
Insert into Jobs(name,Groupid) values ('Task1',1) Insert into Jobs(name,Groupid) values ('Task2',1) Insert into Jobs(name,Groupid) values ('Task3',1) Insert into Jobs(name,Groupid) values ('Task4',1) Insert into Jobs(name,Groupid) values ('Task5',2) Insert into Jobs(name,Groupid) values ('Task6',2) Insert into Jobs(name,Groupid) values ('Task6',2) Insert into Jobs(name,Groupid) values ('Task7',3)
-- New tasks
Insert into Jobs(name) values ('TaskA') Insert into Jobs(name) values ('TaskB') Insert into Jobs(name) values ('TaskC') Insert into Jobs(name) values ('TaskD') Insert into Jobs(name) values ('TaskE') Insert into Jobs(name) values ('TaskF')
This gives us 6 unassigned tasks and a uneven group assignment
I went to look at the connection string previously entered for a dataset created in a new report, and am not seeing anything intuitive for bringing up the associated datasource dialog box that was used to enter name, type and connection string. I'm also noticing nothing intuitive for deleting an existing dataset. How do you do these two very simple things in an existing project? I dont see the dataset in solution explorer, I see it only in the text box on the data tab and in a limited kind of way on the dataset view where the columns show and maint is allowed mostly on the columns only. I tried hilighting the dataset here and hitting the delete key to no avail.
SELECT * FROM bookkeep RIGHT OUTER JOIN acraccts ON LEFT(bookkeep.accnum, 9) = acraccts.p_accnum WHERE (bookkeep.busdate = '03/09/10') AND (bookkeep.tradetype = 'S')
on my sql box, if i run it, i get no data.
i figured out that if i change the where clause to (bookkeep.busdate='2003/09/10') it works
OR
if i simply put SET DATEFORMAT YMD on the first line before the SELECT * that it also works.
my problem is the basic query is hard coded and i really can't change it.
is there a global sql server setting that will make my sql 2000 sp3 box recognize '30/09/10' as 2003/09/10?
create view vwdate as select custno, custname, city, date from salestab where date = ????
well, this question mark...i have to fill..
like i want if month is june then i want for whole may month results of custno, custname and city..
if month is july then i want results for whole june month..
means for previous month results i want whatever the date is for that particular month..
Example:
if date='06/15/08' then results will be custno custname city date --------------------------------- 1 AAAA NJ 05/01/08 2 SDS CT 05/04/08 ........................ 05/18/08 .......................... 05/30/08
if date='06/30/08' OR '06/1/08' then also results will be same.. so i want for previous month results..
so can anyone help me to get the correct condition in where clause?
I wonder if someone could suggest a way to obtain the following. Using SQL Server 2005 I want to create some stored procedures. I want to query the DB with various filter arguments and combinations of these. One way would be to create one stored procedure for each function signature. However, as the number of combinations of filter is large, if possible I'd rather have a generic input to the each stored procedure that corresponds to the entire WHERE clause' search condition.
The stereotype behavior I'm looking for is:
SELECT myField FROM myTable WHERE @mySearchCondition
Does any one have some good suggestion, code samples and/or links?
I'm trying to join two tables based on a like condition. The first table contains the full IP, e.g. '166.27.12.24' and the second contains a 2 octet range, e.g. '166.27', which I need to join.
I have a column with serial numbers 1, 2,3,4,....etc...I want to have P1 for first 4 serial numbers to be displayed in a separate column beside Serial number column and for the next four serial numbers (5,6,7,8) it should be P2 and like that I want till P13 and for next again it should start with P1(I mean after P13 it should give again P1 instead of P14) and continue the same process.
Column name of Serial number is [S.No] table name for example is #temp1
I am facing a challenge and hope some one can help me with the query.
I have a school. School have classrooms. Classrooms are divided into various sections (Section A, Section B and so on) . Sections have subsections. Every student is allocated a rollnumber in that section.(Subsection is just for dividng the sections. it has no other use.) Now the student is given a choice to specify his own roll( DesiredRoll) in that section. If two children select the same rollno, then the system internally allocates a trackingno.(There can be multiple roll no as these are allocated manually by admin). Let me demonstrate this:
So when the first entry is made in the db, and let us say that the section to be allocated is A, RollNo is 1 and the DesiredRoll is 1
Student 1 Section A Subsection 1 Roll No 1 DesiredRoll 1 TrackingNo 0
The second entry is made in the db and let us say the section to be allocated is A, RollNo is 2 and the DesiredRoll is 2
Student 2 Section A Subsection 1 Roll No 2 DesiredRoll 2 TrackingNo 0
Now let us say there is a 3rd entry the section to be allocated is A, RollNo is 3 but the DesiredRoll is 1. Now since the DesiredRoll has already been taken, we will allocate the DesiredRoll 1, however now the trackingNo will be 1
Let us say there is a 4th entry is made, the section to be allocated is A, RollNo is 4 but the DesiredRoll is again 1. Now since the DesiredRoll has already been taken, we will allocate the DesiredRoll 1, however now the trackingNo will be 2
Similarly this logic will work for different sections. How will I write a query so that I can detect this scenario and increment the tracking no or allocate a tracking no of 0 if there is a new entry made in that section
I want to edit(update,delete,insert) target table activity from front end for that I took grid view and that grid all activity come of single student studenid(unique key for each student) that you see design below like this
that activity present in target table that come as check in check and that activity not select student from activity activity table that come unchecked
I want to update above information means unchecked alredy check data should delete and new check data add , already check data update
I have use merge statement but problem is that at single time only one row execute that is check because data come from data gridview.

How to write trigger for this.
Please Note : No ASP code is invloved in this. Only MSSQL coding to be done.
I have a table where I need to concatenate and sum based on conditions given below .
CREATE TABLE #DimOrder ( [ID] [INT] IDENTITY(1,1) NOT NULL, [OrderID] [INT] NOT NULL, [SalesRegion] [VARCHAR](5) NULL, [OrderType] [INT] NOT NULL,

I have one main report which has 5 subreport. i dont want to show all the sub reports all the time. i want to suppress any subreport based on some conditioned. can i do it in case of the SSRS. How?
I have two tables : Students and StuHistory. The structure of the Student table is as follows :
IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[Student]') AND type in (N'U')) BEGIN CREATE TABLE [dbo].[Student]( [RID] [int] NOT NULL, [Class] [int] NULL, [Section] [char](1) COLLATE SQL_Latin1_General_CP1_CI_AS NULL, [SubSection] [int] NULL, [RollNo] [int] NULL, [DesiredRoll] [int] NULL, [TrackingNo] [int] NULL, [Original_rollno] [int] NULL, [StudentStatus] [int] NULL ) END GO
A section has subsections where students are allocated rollno's. Every student has a unique roll no in that subsection. However he is also given a choice to enter his desired roll no. If more than one student choose the same desired roll no in that subsection/section, there is a [TrackingNo] field that then starts keeping a count. For the first unique desired roll no in that subsection/section the tracking no is always 0. [StudentStatus] represents the following : (-1 for deleted, 0 for edited, 1 for newly inserted).
After every fortnight, i have to run a batchquery that does the following:
1. all students marked with -1 are moved to a table called StuHistory which has the same structure as that of Student.
2. Now oncethe -1 status students are moved, there will be a gap in the roll no. I want to reallocate the rollnos now, where rollnos = desired roll no taking into consideration the trackingno
So if 4 students have chosen the desired roll no as 5 and their current roll no is scattered in a subsection lets say 7, 10, 14,16, then while rearranging they will be together(grouped by subsection/section) and will be allocated roll no's 5,6,7,8. The other students will be moved down based on their desired roll nos. Over here i have to also fill the gaps caused because of the students who were deleted.
How do i write query for this? I have been struggling.
I thought of posting this as a new post as it was mixed in the previous post.
CREATE PROCEDURE [dbo].[GetProspectBySearch] @StartRowIndex AS INT, @MaximumRows AS INT, @ModuleType AS VARCHAR(50) = NULL, @ProspectCategory AS VARCHAR(50) = NULL, @ProspectsWithoutContact AS BIT = NULL AS BEGIN IF @Status = 'All' BEGIN SET @Status = NULL END
[code]....
1) How do I can write count and paging statements in to single statement ? 2) There is parameter @ProspectsWithoutContact is using for differentiation for count and paging statements. If @ProspectsWithoutContact is "1" then this clause ( AND ContactPerson = NULL AND TelNo = NULL AND FaxNo = NULL) will be added in to both count and paging statements. How do I can write this in to single statement with out IF ELSE ?
My requirement is below.enhancing the T- sql query as I was told not to use SSIS.
Insert data from Table A to Table B with conditions:
1. Truncate gender to one character if necessary.
2. Convert character fields to uppercase as necessary.
3. For systems that supply both residential and mailing addresses, use the residential address if available (both street_address and zip fields have value), mailing address otherwise.
In SSIS I took conditional split with 'ISNULL(res_street_address) == TRUE || ISNULL(res_zip) == TRUE '
default outputname :Consider Res Address; Outputname:Consider mail address.
and mapped as:
(Table A) mail_street_address---street address(Table B)
(Table A) mail_city----------------City(Table B)
(Table A) mail_Zip----------------Zip(Table B)
(Table A) mail_state-------------state(Table B)
(Table A) res_street_address--street address(Table B)
(Table A) res_city---------------City(Table B)
(Table A) res_Zip----------------Zip(Table B)
(Table A) res_state--------------state(Table B)
I want to do the same with T-sql code too:
I came up with below T-SQl but unable to pick(street,city,state,zip columns as I have take combination of street and zip from Table A not individual columns as I wrote in below query) based on above condition(3):
Insert into TABLE B SELECT Stats_ID ,UPPER(first_name) first_name ,UPPER(middle_name )middle_name ,UPPER(last_name) last_name ,UPPER(name_suffix) name_suffix
When the value of Downtime is greater than 0:00:10 I would like to have the background of that cell to be Red and its font bold. How to accomplish this in query?
hello all,this might be simple:I populate a temp table based on a condition from another table:select @condition = condition from table1 where id=1 [this will giveme either 0 or 1]in my stored procedure I want to do this:if @condition = 0beginselect * into #tmp_tablefrom products pinner joinsales s on p.p_data = s.p_dataendelsebeginselect * into #tmp_tablefrom products pleft joinsales s on p.p_data = s.p_dataendTha above query would not work since SQL thinks I am trying to use thesame temp table twice.As you can see the major thing that gets effected with the condictionbeing 0/1 is the join (inner or outer). The actual SQL is much biggerwith other joins but the only thing changing in the 2 sql's is the joinbetween products and sales tables.any ideas gurus on how to use different sql's into temp table based onthe condition?thanksadi
Here we need consider patient dates that fall between sdate and edate of the patientrefs table, and then we need to consider the highest status values in order (for example, the highest values in order - 2 is first highest, 4 is second highest, 3 is third highest, and 1 is fourth highest value)
If the date falls between multiple different sdate and edate with the same status values, then we need to consider the latest sdate value and from that entire record we need to extract that value.
Here, pn=2 values have dates which fall between sdate and edate of patientref table. Then we give highest values status is 2, and status 2 values have two records, then we go for max sdate(latest sdate). Then this pn=2 latest sdates is 2015-02-10 and we need to retrieve the corresponding edate and status values.
pn = 4donot have sdate and edate and status values dut not fall conditon
select p.pn,p.code,p.[date],p.doctorcode,pr.sdate,pr.edate,pr.[status] from patient p outer apply (select top 1 pr.pn,pr.code,pr.sdate,pr.edate,pr.[status] from patientref pr where pr.pn=p.pn and pr.code=p.code and p.date between pr.sdate and pr.edate order by case when pr.status=2 then 1 when pr.status=4 then 2 when pr.status=3 then 3 when pr.status=1 then 4 end ,pr.sdate )pr
but this query not given expected result.here when dos not fall between sdate and edate that records not given in the above query. I required that records also.if not fall b/w condition then we need retrive that records empty values for that records.
