T-SQL (SS2K8) :: Merge Multiple Rows In Single Row
Jul 8, 2015
I've a requirement where I need to merge multiple rows in single rows. For example in the attached image output, I need to return a single column for type Case like this.
CH0, CH1, CH2, CHX Case
CM0, CM1, CM2, CMX Mechanical
I'm using T-SQL to generate the column type. Below is my DDL.
USE tempdb
GO
CREATE TABLE ProdCodes
(Prefix char(8),
Code char(5)
I have two tables of news feed NewsHeader & NewsDetails NewsHeader: Time Header 10:15:34 AM News1 10:15:34 AM News1 10:15:34 AM News1 11:19:39 AM News2 11:19:39 AM News2 12:35:04 PM News3 12:35:04 PM News3

I am working with some old code that we are trying to clean up and perform some performance enhancements. The performance is now, so Very much better. From over 3 minutes to under 2 seconds.
But I am still trying to get the multiple rows into a single row. I would like to place this into a CTE to get the multiples into a single row. I just cannot get my head around how is the best, most efficient way to write the query.
This is a small example of what the rows look like in the resultset, and what I want to single to be.
DECLARE @BillingCorrect TABLE ( ContractNumber char(10) , pc1 int , pb int , om int , vp int
[Code] ....
I am not sure how to write the query to have all the data in a single row.

I have resulting rows from a query similar to the following:
The data is coming from a single table that contains only one coverage code column and one coverage code date, but the end user wants the two coverage code types and dates combined into a single row. So the SELECT looks something like this:
SELECT [Employee ID] = emp.employee_id, [Coverage Code 1] = enr.coverage_code, [Coverage Date 1] = enr.coverage_date, [Coverage Code 2] = case when enr.product_type = 'Accident.Accident' then enr.coverage_code else NULL end,
[Code] ....
I basically want to merge the like Employee ID's together into a single row like the following:
I know I have done this before and it is probably pretty simple.
SELECT 'Type'[Type] ,CASE WHEN code='09' THEN SUM(Amt/100) ELSE 0 END ,CASE WHEN code='10' THEN SUM(Amt/100) ELSE 0 END ,CASE WHEN code='11' THEN SUM(Amt/100) ELSE 0 END ,CASE WHEN code='12' THEN SUM(Amt/100) ELSE 0 END FROM Table1 WHERE (Code BETWEEN '09' AND '12') GROUP BY Code
and the output
Column 1 Column 2 Column 3 Column 4 Type 14022731.60 0.00 0.00 0.00 Type 0.00 4749072.19 0.00 0.00 Type 0.00 0.00 149214.04 0.00 Type 0.00 0.00 0.00 792210.10
How can I modify the query to come up with output below,
Scenario is like that single dept can have multiple LocationHeads, If Location heads are multiple then they should display in single column using *starting the name as mentioned bottom under required output.
Below is sample of data:
create table #Temp(depID int, Name varchar(50),LocationHead varchar(50)) insert into #temp values(1,'test','head1') insert into #temp values(1,'test','head2') insert into #temp values(1,'test','head3') insert into #temp values(2,'test1','head1') insert into #temp values(2,'test1','head2')
Required output
depID Name LocationHead 1test *head1,*head2,*head3 2test1 *head1,*head2
Can we insert into multiple table using merge statement?I'm using SQL Server 2008 R2 and below is my MERGE query...
-> I'm checking if the record exist in Contact table or not. If it exist then I will insert into employee table else I will insert into contact table then employee table.
WITH Cont as ( Select ContactID from Contact where ContactID=@ContactID) MERGE Employee as NewEmp Using Cont as con
I am trying to replace all special characters in a column with one special character.
Example:
Table: dbo.Employee Column: Name Name ------- edwardneuman!"<] mikemoreno)'>$: JeffJensen"?>"
I am trying to get the namepart to the left of ANY special character. To achieve this, I am thinking of replacing all the special characters with a single special character so that I can find the first occurrence of that special character and grab left of the special character (SUBSTRING/CHARINDEX). This way I don't need to loop through all the special characters.
I am expecting the following results:
Name ------- edwardneuman<<<< mikemoreno<<<<< JeffJensen<<<<
I have multiple databases in the server and all my databases have tables: stdVersions, stdChangeLog. The stdVersions table have field called DatabaseVersion which stored the version of the database. The stdChangeLog table have a field called ChangedOn which stored the date of any change made in the database.
I need to write a query/stored procedure/function that will return all the database names, version and the date changed on. The results should look something like this:
There will be one UniqueID for each row. We'll get the uniqueID and PK1 and PK2 in a file. Imp: We need to generate the Sequence_Id depending on number of Issue_dates or Issue_amounts or Issue_Categories or Issue_Rejects as in the above table.
Can we do this without using cursors? This is going to be one time process.
I've a temp variable where I'm moving some columns like below:
id value type1 type2
0 ab type1val1 type2val1
0 cd type1val1 type2val1
0 ef type1val1 type2val1
1 ab type1val2 type2val2
1 cd type1val2 type2val2
1 ef type1val2 type2val2 What I want to do is group these by their id and get the following o/p ab,cd,ef type1val1 type2val1 ab,cd,ef type1val2 type2val2
The grouped values need to be separated by commas.
What I'm doing currently: I'm using a temp variable to put all these values but am unable to coalesce and get the desired o/p.
I have a table that contains many columns in a single row and I'd like to split the table so that it has fewer column values and more rows. My table structure is: create table #scoresheet (Decisions varchar(10), DNumericalValue int, DVI varchar(10), DComments nvarchar(255), Competence varchar(10), CNumericalValue int, CVI varchar(10), CComments nvarchar(255), Equipment varchar(10), ENumericalValue int, EVI varchar(10), EComments nvarchar(255)); I would like to have three rows with four columns. What I've done so far is create a stored procedure that uses a table variable: create procedure sp_splitsinglerow as
declare @Scoresheet_rows_table_var table ( ReviewArea varchar(25), NumericalValue int, VI varchar(10), Comments nvarchar(255)); insert into @Scoresheet_rows_table_var (ReviewArea, NumericalValue, VI, Comments) select Decisions, DNumericalValue, DVI, DComments from #scoresheet
The trouble with this approach is that I have to explicitly name the columns that I insert into the table variable. What I'd really like to be able to is have a loop construct and select the first 4 columns the first time, the second 4 the next time and the last 4 the third time.
Any ideas on how to achieve that?
BTW, I have resolved this issue by suggesting to the Developers that they change the structure of the original table, but I'd still like to know if there is another solution. :)
Hi I have aproble with stored procedure.I want to take the Data from a table with multiple rows,In the same select statement for the others select statemet.My store Proc is like this..
CREATE procedure spr_Load_TR_AccidentReport_Edit_VOwner ( @Crime_No varchar(20), @Unit_ID int ) as begin DECLARE @AD_Driver int,@AC_Cas int,@AV_Owner int,@A_Witness int DECLARE @Defect_ID varchar(100)
select @AV_Owner=Vehicle_Owner from TBL_TR_ACCIDENT_VEHICLE where Crime_No =@Crime_No and Unit_ID = @Unit_ID
(select TBL_TR_Person_OutsideDetails.OutSide_state from TBL_TR_Person_OutsideDetails,TBL_TR_ACCIDENT_VEHICLE where TBL_TR_ACCIDENT_VEHICLE.Vehicle_Owner = TBL_TR_Person_OutsideDetails.Person_id and TBL_TR_ACCIDENT_VEHICLE.RowID =TBL_TR_Person_OutsideDetails.RowID)[OutSide_state],
(select TBL_TR_Person_OutsideDetails.OutSide_City from TBL_TR_Person_OutsideDetails,TBL_TR_ACCIDENT_VEHICLE where TBL_TR_ACCIDENT_VEHICLE.Vehicle_Owner = TBL_TR_Person_OutsideDetails.Person_id and TBL_TR_ACCIDENT_VEHICLE.RowID =TBL_TR_Person_OutsideDetails.RowID)[OutSide_City]
---here I faced the problem- /*For the above Select only return one rows.But this select willreturn multiple row .I wnat to put that multiple data into a single field with comma*/
(SELECT @Defect_ID = COALESCE(@Defect_ID + ',','') + CAST(TBL_TR_VEHICLE_DEFECT.Defect_ID AS varchar(5)) FROM TBL_TR_VEHICLE_DEFECT,TBL_TR_ACCIDENT_VEHICLE WHERE TBL_TR_VEHICLE_DEFECT.Registration_Number =TBL_TR_ACCIDENT_VEHICLE.Registration_Number) select @Defect_ID
FROM tbl_TR_Accident_report,TBL_TR_Person_Details,TBL_TR_ACCIDENT_VEHICLE where tbl_TR_Accident_report.Crime_No=@Crime_No and tbl_TR_Accident_report.Unit_ID=@Unit_ID AND TBL_TR_ACCIDENT_VEHICLE.Crime_No=@Crime_No AND TBL_TR_Person_Details.Person_ID = TBL_TR_ACCIDENT_VEHICLE.Vehicle_Owner
I'm working on a script to merge multiple columns(30) into a single column separated by a semicolons, but I'm getting the following error below. I tried to convert to the correct value. but I'm still getting an error.
Error: "Conversion failed when converting the varchar value ';' to data type tinyint".
Basically if the type code is 1 one then move the data to column phone1, if the type is 2 then move it to column phone2.
This would be fairly simple if we always have type codes 1 and 2. But sometimes we can have type 1 and not type 2, or we could have type 2 and not type1.
Right now we only have 2 type codes. But, in the future we could be adding a 3rd type. So that would add a 3rd column (phone3).
Below is my code that I have written. I move the data into a temp table then list it. I am thinking of making this a view to my table. It works just fine. My question is, is there a better and more efficient way of doing this?
CREATE TABLE #Contacts ( id INT PRIMARY KEY, phone1 VARCHAR(15), phone2 VARCHAR(15) )
-- Insert the records for type 1
INSERT INTO #Contacts SELECT id, phone_num, NULL FROM test1 WHERE type_code = '1'
-- Insert the records for type 2, if the id does not exist for type 1
INSERT INTO #Contacts SELECT id, NULL, phone_num FROM test1 WHERE NOT EXISTS ( SELECT 1 FROM #Contacts WHERE #Contacts.id = test1.id ) AND test1.type_code = '2'
-- if the id has both type 1 and 2, update the phone2 column with the data from type 2
UPDATE #Contacts SET phone2 = test1.phone_num FROM #contacts JOIN test1 ON test1.id = #Contacts.id WHERE type_code = '2' SELECT id, phone1, phone2 FROM #Contacts DROP TABLE #Contacts
I need to update a empty column in our SQL database with the login ID for employees of our company.The table is called SY01200 and were I need to put the login ID is column INET5, and the login ID is just me stripping off the company's email address(removing the @company.com), and I need to update the INET5 column only where Master_Type = 'EMP'
And here is the Query that I am using to strip the email select LEFT(convert(varchar(40),EmailToAddress),LEN(convert(varchar(40),EmailToAddress))-14) As LoginName from sy01200 where Master_Type = 'emp'And here is what I thought the Query would be to update however I got and error saying more than 1 arguement returned
UPDATE sy01200 SET INET5 = (select LEFT(convert(varchar(40),EmailToAddress),LEN(convert(varchar(40),EmailToAddress))-14) As LoginName from sy01200 where Master_Type = 'emp') WHERE Master_Type = 'EMP'
With the below query iam able to retrieve all the tables invloved in a stored proc. But, what I want to display the table names as comma separated list for each table.
;WITH stored_procedures AS ( SELECT o.id, o.name AS proc_name, oo.name AS table_name, ROW_NUMBER() OVER(partition by o.name,oo.name ORDER BY o.name,oo.name) AS row FROM sysdepends d INNER JOIN sysobjects o ON o.id=d.id INNER JOIN sysobjects oo ON oo.id=d.depid WHERE o.xtype = 'P') SELECT id,proc_name, table_name FROM stored_procedures WHERE row = 1 ORDER BY proc_name,table_name
