Concatinating With Cursor
May 6, 2008 frenz:
Can any one send me the code for
concatinating cells values of column in to one cell of that column using cursors.
Ex:
hobbyID
h1
h2
h3
hobbyId
h1,h2,h3

Concatinating Columns
Aug 8, 2006Hello all.
I am taking details from a linked server file (.XLS file). Two of the fields in this file are STARTTIME and STARTDATE.
The problem I have is that these have to be imported into a SQL table, but only into one column of type DATETIME. The column name is STARTDATE. I really have no idea on how to go about this. Any ideas would be greatly appreciated.
Thanks.
Concatinating Variables
Jul 20, 2005Hello,How do I concatinate a variable. Here's the scenarios:declare @var1 varchar(20)declare @var2 varchar(20)declare @var3 varchar(20)declare @var4 varchar(20)....declare @var32 varchar(20)set @var1 = 'Something 1'set @var2 = 'Something 2'....set @var32 = 'Something 3'/* I have to store the values of these individual variables. I wish tohave a "While" routine which iterates through the above variables. Iwish to have the variable name concatinated as that I do not have towrite numerous lines of code setting up individual 32 variables. Howcould I use the '+' operator to join 'var' + @count . Where count isfrom 1 through 32. I am having some trouble with the syntax.*/Regards,VS
View 7 Replies View RelatedConcatinating Select Results
Jan 18, 2006Hey everyone,
I have an SSIS conversion issue. I'm pulling two tables from a DB2 database into SQL 2005. One table has a list of work orders, and the other has a list of work order comments. There is a unique identifier between the two tables so that a join can be used, however, due to size limitations, I need to be able to combine both tables.
The end result will be replicated out for SQL Mobile Edition and the file is too large when both tables exist so I am wanting to concatinate all the comments for each work order into a single text field in the work orders table.
Here is what I am wanting to accomplish:
UPDATE tblWorkOrdersSET Comments = (SELECT Comments
FROM tblComments
WHERE tblWorkOrders.ReqNum =
tblComments.ReqNum)
I know that this statement will not work because there is a one-to-many relationship between the tables so each work order could get multiple results.
I would appreciate any suggestions.
Thanks,
Lee.
Concatinating SmallInt Data Type
Aug 20, 2007Newbie question regarding a db I have inherited. A table FullDocuments has a DocNo column with smallint data type and a SequenceNo column also with smallint data type.DocNo
has numbers that represent persons. SequenceNo has numbers that
represent specific documents associated with each person (DocNo).So DocNo 5 and Sequence 3 represents the 3rd document associated with person 5.My SELECT statement looks like this:SELECT ReadingNo, SequenceNoThis returns data like this: 5 3I would like to concatenate the SELECT statement to return like this: 5-3So I made Sql like this:SELECT ReadingNo + '-" + SequenceNo Which
returns a alias ('No Column Named') result value of 8 which is an
arithmetic result instead of a string concatination that I want.So my questions are:1.
Should the original database designer have used string data types for
these columns since they will never be used for math purposes?2.
Do I need to cast them to string data type (like nchar(4) - since
neither column will ever exceed 4 digits) to get the result I desire?3. Or can I keep them as smallint and modify my SELECT statement to allow concatination yielding a string result?

Problem In Concatinating Two Paramters To Update One Column
Sep 20, 2007 Using gridview to display the data and sql server 2000 I have
a column in the database say departtime of datetime datatype that
cntains the date and time resp(09/19/2007 9:00 PM). I am separating the
date and time parts to display in two different textboxes say
txt1(09/19/2007) contaons date and txt2(9:00 PM) contains time by using
the convert in sqldatasource. Now i need to update the column in the
database and i am using Updatecommand with parameters in aspx lke
updatecommand = "Update table set departtime = @departtime" . How can
i update my column as datetime by getting the data from 2 texboxes as
now i have 2 textboxes displaying data for single column means if user
edit the data in txt1 as(10/19/2007) then on click of update i need to
populate the column daparttime as (10/19/2007 9:00 PM).Please let me know if you have any questions.
Concatinating String Values From Multiple Rows
Nov 4, 2006I currently have some SQL code that is used to build a string that is a concatination of string values across multiple rows. The subqueries in the script sometimes return NULL values so I use the following statement to change the default behavior of the concatination operator which prevents my query from returning NULL:
SET CONCAT_NULL_YIELDS_NULL ON
Here's the code snippet:
select DISTINCT
(SELECT CASE WHEN (t1.MaskValue & HDR.TranTypeID)=1 THEN ' ' + t1.description ELSE '' END FROM transactiontypes t1 WHERE (t1.MaskValue & HDR.TranTypeID)=1) +
(SELECT CASE WHEN (t2.MaskValue & HDR.TranTypeID)=2 THEN ' ' + t2.description ELSE '' END FROM transactiontypes t2 WHERE (t2.MaskValue & HDR.TranTypeID)=2) +
(SELECT CASE WHEN (t3.MaskValue & HDR.TranTypeID)=4 THEN ' ' + t3.description ELSE '' END FROM transactiontypes t3 WHERE (t3.MaskValue & HDR.TranTypeID)=4) +
(SELECT CASE WHEN (t4.MaskValue & HDR.TranTypeID)=8 THEN ' ' + t4.description ELSE '' END FROM transactiontypes t4 WHERE (t4.MaskValue & HDR.TranTypeID)=8) +
(SELECT CASE WHEN (t5.MaskValue & HDR.TranTypeID)=16 THEN ' ' + t5.description ELSE '' END FROM transactiontypes t5 WHERE (t5.MaskValue & HDR.TranTypeID)=16)) as 'Transaction Type'
FROM HDResponse HDR
Here's the underlying table structure:
CREATE TABLE [dbo].[TransactionTypes](
[ID] [int] IDENTITY(1,1) NOT NULL,
[Description] [varchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL, [MaskValue] [int] NOT NULL) ON [PRIMARY]
CREATE TABLE [dbo].[HDResponse](
[ResponseID] [int] IDENTITY(1,1) NOT NULL,
[LoggedDateTime] [datetime] NULL,
[ResponseTypeTripID] [int] NULL,
[ResponseTypeID] [int] NULL,
[ResponseTypeObjectID] [int] NULL,
[ObjectID] [int] NULL,
[IDHolderID] [int] NULL,
[TransportCode] [int] NULL,
[CardID] [int] NULL,
[IssueCode] [smallint] NULL,
[EventDateTime] [datetime] NULL,
[Response] [bit] NULL,
[TranTypeID] [int] NULL)
ON [PRIMARY]
The problem I am having is I need to be able to use the query above in a view used for reporting. Unfortunately, you cannot use SET CONCAT_NULL_YIELDS_NULL ON in a view. This causes my query to return NULL if any of the subqueries return NULL. I could create a function to do something similar and reference the function in the query but I can't help but think there must be a way to get this done in a single query.
Any thoughts or ideas would be greatly appreciated.
Thanks!!!!!
Transact SQL :: STATIC Defines A Cursor That Makes Temporary Copy Of Data To Be Used By Cursor
Aug 12, 2015 In MSDN file I read about static cursor
STATIC
Defines a cursor that makes a temporary copy of the data to be used by the cursor. All requests to the cursor are answered from this temporary table in
tempdb; therefore, modifications made to base tables are not reflected in the data returned by fetches made to this cursor, and this cursor does not allow modifications
It say's that modifications is not allowed in the static cursor. I have a questions regarding that
Static Cursor
declare ll cursor global static
for select name, salary from ag
open ll
fetch from ll
while @@FETCH_STATUS=0
fetch from ll
update ag set salary=200 where 1=1
close ll
deallocate ll
In "AG" table, "SALARY" was 100 for all the entries. When I run the Cursor, it showed the salary value as "100" correctly.After the cursor was closed, I run the query select * from AG.But the result had updated to salary 200 as given in the cursor. file says modifications is not allowed in the static cursor.But I am able to update the data using static cursor.
Dynamic Cursor Versus Forward Only Cursor Gives Poor Performance
Jul 20, 2005Hello,I have a test database with table A containing 10,000 rows and a tableB containing 100,000 rows. Rows in B are "children" of rows in A -each row in A has 10 related rows in B (ie. B has a foreign key to A).Using ODBC I am executing the following loop 10,000 times, expressedbelow in pseudo-code:"select * from A order by a_pk option (fast 1)""fetch from A result set""select * from B where where fk_to_a = 'xxx' order by b_pk option(fast 1)""fetch from B result set" repeated 10 timesIn the above psueod-code 'xxx' is the primary key of the current Arow. NOTE: it is not a mistake that we are repeatedly doing the Aquery and retrieving only the first row.When the queries use fast-forward-only cursors this takes about 2.5minutes. When the queries use dynamic cursors this takes about 1 hour.Does anyone know why the dynamic cursor is killing performance?Because of the SQL Server ODBC driver it is not possible to havenested/multiple fast-forward-only cursors, hence I need to exploreother alternatives.I can only assume that a different query plan is getting constructedfor the dynamic cursor case versus the fast forward only cursor, but Ihave no way of finding out what that query plan is.All help appreciated.Kevin

Client Side Cursor Vs Sever Side Cursor?
Jul 20, 2005I having a difficult time here trying to figure out what to do here.I need a way to scroll through a recordset and display the resultswith both forward and backward movement on a web page(PHP usingADO/COM)..I know that if I use a client side cursor all the records get shovedto the client everytime that stored procedure is executed..if thisdatabase grows big wont that be an issue?..I know that I can set up a server side cursor that will only send therecord I need to the front end but..Ive been reading around and a lot of people have been saying never touse a server side cursor because of peformance issues.So i guess im weighing network performance needs with the client sidecursor vs server performance with the server side cursor..I am reallyconfused..which one should I use?-Jim
View 1 Replies View RelatedNeed Help With A Cursor
Jul 25, 2006I hope this is the appropriate forum for this question, if not then I apologize.
I've got a SQL Server 2000 stored procedure that returns data to be used in a crystal report in Visual Studio 2005. Most of the stored procedure works well, but there is a point where I need to calculate an average number of days been a group of date pairs.
I'm not familiar with cursors, but I think that I will need to use one to achieve the result I am looking for so I came up with the code below which is a snippet from my stored procedure. In this part of the code, the sp looks at the temporary table #lmreport (which holds all of the data that is returned at the end to crystal) and for every row in the table where the terrid is 'T' (the territory is domestic), it selects all of those territories from the territory table and loops through them to determine the date averages (by calling a nested stored procedure, also included below) for each territory and then updates #lmreport with that data.
When I try to run the stored procedure, I get "The column prefix '#lmreport' does not match with a table name or alias name used in the query." on the line indicated.
Does anyone have any idea what might be wrong or if this will even work the way I need it to?
Thank you in advance.

Apr 4, 2006Hello, I'm trying to construct a cursor that will sequentually increment a number and then update a column with the incremented number. My propblem is that all the rows in the table are being updated with the base number +1. So all rows are updated with 278301. BUT, what I really want is for only the items with adrscode of 'bill to' to be given an incremented number.
For example, if there are only five rows of 100 with an adrscode = 'bill to' then only five rows will be updated and the value of the custnmbr should be, 278301, 278302, 278303 .....
I could really use some help with this cursor:

Cursor Help!
Apr 22, 1999This is what I am trying to do:
Table 1 has numerous resume's for each person. Each resume has a unique id.
ie: Table 1
res_id fname lname userid pwd address city state etc...
100 John Doe jd ok xxxx xxxx xx xxxx
104 Sally May sm sm ccccc cc c cc ccc
643 John Doe jd ok ssss null null
1003 John Doe jd ok 123 elm Nome AK ...
5000 Tom Cat tc tc null null null
I need to insert into Table 2 only the demographic information for each person appearing in Table 1. The catch is that Table 2 doesn't have the same unique id that appears in Table 1. userid and pwd are unique to Table 2 but are numerous in Table 1.
Table 2
new_ident userid pwd address city state etc..
10 jd ok 123 elm Nome AK ....
11 Sally May sm sm ccccc cc c cc ccc
12 Tom Cat tc tc null null null
Basically I need to choose the most current "max(res_id)" occurance for John Doe above to get only one row out of his three rows. Then I need to get all the other unique rows from table 1.
I hope that is clear. I was considering a cursor. Any ideas??

Can I Do This Without A Cursor?
Jul 8, 2002Here's what I' trying to do...
I am writing an application for a training facility. I have three tables in particular that I'm concerned with.
Here they are with the relevent keys
1. Registrations - contains a customerid and a classid
2. Sessions - contains a classid (multiple sessions can exist for a class)
3. Attendence - contains a session and a customerid.
Whenever I insert a session record for a class, I want to automatically create a corresponding record in the attendence table for every student in the class . My only thought is to create an insert trigger on the session table than creates creates a cursor containing the customerid for every student registered in the class. Then I can walk through the cursor and insert an Attendence record for each student.
I really don't want to use a cursor if I can help it, but I can't think of a way to write an single INSERT statement to put into my trigger. Is there a way to do this without using a cursor?
Any thoughts would be appreciated.

It Is Possible With Cursor?
Jul 5, 2004I need to fill a cursor with 3 columns.
A want to use a Select sprocs (for re-use de code), but this sproc return 15 columns and the 3 a need was not the 3 frist. :confused:
Do I need to map the 15 columns with 15 variables locally? Or they have a way easier?
Thanks
Can I Use SQL Instead Of Cursor?
Oct 6, 2004Hi,
I'm currently converting a VB function to SQL-Server. The function uses a cursor to find the "terms of delivery" (TOD) with the highest priority.
I have a table with articlenumber, tod (and lots of other columns that doesn't matter now)
ABC123 , AFG
ABC123 , AFG
ABC123 , BGH
ABC123 , BGH
ABC123 , CDD
"CDD" has the highest priority and therefore ALL with the same articlenumber should use that tod.
The existing function uses a cursor and loops through a recordset and updates every row with the same articlenumber as the current row with the tod with the highest priority (of the ones read) with the same articlenumber.
One update per row takes "forever" to run...
I figured it would be possible to select the tod with the highest priority for one articlenumber into a temp table and then do ONE update to set the tod on all rows...
