Need An Optimal Way To Merge External Dataset To Database Values
Jan 3, 2008
C# .Net Application as front end
Sql Server2000 as back end
I need to merge an external dataset from .Net app(in XML format) with the information in database with one column in database table as the merging criteria. A situation similar to Left Outer Join, wherein i need all records from external dataset and if matched in database the corresponding values from there too, the only difference here is that the join is not between two Tables its between a table and external dataset.
There is no need to store the external dataset in the database in persistent form, its just a query - merge - response operation.
So, can anyone suggest the best possible solution for this? A table variable / temporary table / some other schema, what and how?
Thanks in advance..

Hello,First, I tried to find the answet to this question, but no luck - so I decided to post it.
When I was creating my applications in asp.net - for the first time I decided to start using external DataSets. I think they are great and work very nice!But once I pushed the application to GoDaddy, I got an error of this nature:I was trying to access the exterbal dataSet like this:Dim productsAdapter As New NorthwindTableAdapters.ProductsTableAdapter()
Dim products as Northwind.ProductsDataTable...And got an error saying that it couldn't find this type (but it worked fine on my local machine in visual studio).So did I miss something that prevented this application working on GoDaddy? or there are some limitations on GoDaddy? ...or something else.Thank you for looking into this for me.Valera

I need to create a report in SSRS 2015 but I need to bind that report to an external dataset .
I need it to work with parameters and stored procedure.
Another issue is that the report is standalone -rdlc.
Can I call the report from a webservice .asmx not wcf and render it automatically in pdf format?

What is more efficient for a database design - a lot of tables with only a few records or a few tables with lots of records.
I'm starting a new site and each user will have numerous records but I'm not sure whether to have a few very large tables (over 100,000 rows) or start a new table for each user which would result in approx 1500 tables most of which would be the same table design with different rows.
I'm using SQL2000.
I guess this is quite a basic question, but I'm a bit unsure.
Any references anyone could point me too as well.
Thx

Hi,
I have two datasets in my report, D1 and D2.
D1 is a list of classes with classid and title
D2 is a list of data. each row in D2 has a classid. D2 may or may not have all the classids in D1. all classids in D2 must be in D1.
I want to show fields in D2 and group the data with classids in D1 and show every group as a seperate table. If no data in D2 is available for a classid, It shows a empty table.
Is there any way to do this in RS2005?

Hello all,
I am trying to think my way through a solution which I believe others have probably come across... I am trying to implement a matching routine wherein I need to match an address against a high value and a low value (or, for that matter an input date vs. a start and end date) to return the desired row ... i.e. if I were to use a straight vb program I would just use the following lookup:
"SELECT DISTINCT fire_id, police_ID, fire_opt_in_out, police_opt_in_out FROM ipt_tbl " & _
" WHERE zip_code = @zip_code AND addr_prim_lo <= @street_number AND addr_prim_hi >= @street_number " & _
" AND addr_prim_oe = @addr_prim_oe AND street_pre = @street_pre AND street_name = @street_name " & _
" AND street_suff = @street_suff AND street_post = @street_post " & _
" AND (expiry_date = '' OR expiry_date = '00000000' OR expiry_date > @expiry_date)" & _
" GROUP BY fire_ID, police_ID, fire_opt_in_out, police_opt_in_out"
My question, then, is how would you perform this type of query using a lookup / merge join or script? I have not found a way to implement a way to set the input columns? I can set the straight matches without a problem, i.e. lookup zip code = input zip code, but can't think of the correct way to set comparisons, i.e. lookup value 1 <= input value AND lookup value 2 >= input value
Any suggestions?
thanks for your time...

Hello guyz,
I am using SQL server and I want to merge two datasets. I have two tables which are similar in structure-(same number of columns). I want to display these two tables in one datagrid. I have 5 rows in the first table and 3 on the other. So in the datagrid it should have 8 rows. Part of my code is below…
ConnectToDatabaseServer()
Dim querystr As String = ("Select username, password from PublicAccounts")
Dim da As SqlDataAdapter = new SqlDataAdapter(querystr, myConnection)
Dim ds1 As DataSet = new DataSet()
da.Fill(ds1, "firsttable")
querystr = ("Select username, password from EmployeeAccounts")
Dim da2 As SqlDataAdapter = new SqlDataAdapter(querystr, myConnection)
Dim ds2 As DataSet = new DataSet()
da2.Fill(ds2, "secondtable")
ds1.Merge(ds2,False, System.Data.MissingSchemaAction.Add)
MergeGrid.DataSource = ds1
MergeGrid.DataBind()
myConnection.Close()
This code only displays the contents of ds1 (5 rows).
My table structure are as follows:
PublicAccounts (username Char(50), password char(50), pid integer primary key)
EmployeeAccounts (username Char(50), password char(50), eid integer primary key)
I really would appreciate any help.
Thank you..

Hi,
I have developed an application where i am inserting all the records from the dataset into sql mobile 2005. Dataset contains a primary key which is an uniqueidentifier datatype. While inserting the data it is inserting properly into the database but it is changing the value of primary key which is in the dataset.
I am using the below syntax, please suggest me so that to avoid creating a different uniqueidentier key into the database.
conAdap = new SqlCeDataAdapter(strQuery, conSqlceConnection);
SqlCeCommandBuilder cmdBuilder = new SqlCeCommandBuilder(conAdap);
conAdap.AcceptChangesDuringFill = false;
conAdap.Fill(dsData);
conAdap.MissingMappingAction = MissingMappingAction.Passthrough;
conAdap.InsertCommand = cmdBuilder.GetInsertCommand();
conAdap.InsertCommand.Connection = conSqlceConnection;
int r =conAdap.Update(dsData.Tables[0]);
Thank you,

I have a strongly typed dataset, and I need to be able to do a search on multiple values of a parameter. The problem is I don't know how many. I have a textbox that the user can enter search words in. The select string is built from the string of words that are entered, like this:For iCount = 0 To UBound(sArray) strSQL = strSQL & "Description LIKE '%" & sArray(iCount) & "%' OR "Next Can I do this is a dataset method?

Hi,
I am mapping an entity from SQL 2005 to another entity in another system on SQL 2000. Since the destination system has its own ID generator, I want to keep the generated ID for each row of my table in a column of my table in SQL 2005. The new column is in the dataset now , but I don't know how to update my table to have that column values (The OleDbDestination just insert new items.)

I am using RDLC report with Microsoft visual studio 2005. In the first page of rdlc i have two text boxes and one table in body section. In the second and subsequent pages i want to repeat the data from textbox1 and textbox2 along with table data continuation of page1.
Currently the continuation of table data from page1 to page2 is working properly. But the textbox1 and textbox2 data also needs to be repeated in every pages.
I tried the following steps, but fails to work.
1. added two text boxes in header section and another two text boxes in Body section.
2. Assigns the dataset value to textboxes in body section.
(Ex: =first(Fields!Address.Value)
3. Assigns the textboxes value from Body section to the corresponding text boxes in header section.
(Ex : =first(ReportItems!textbox1.Value))
Result:
The header text box value displayed in the first page only and not repeated in the subsequent pages.
Expected:
Whatever assigned to the header section should be repeated in the subsequent pages. But only page number, date... is reflecting in other pages and not the text box values in header section.
Kindly give me the solution.
Thanks in advance.

Hi.
In my report, I need to display column names (and its values) from my dataset, which uses the stored procedure and within it use the PIVOT statement. I cannot use the matrix control in report since I need to add another static column to the right of the matrix, but since that cannot be done ni SQL SSRS 2005, I need to PIVOT it through stored procedure. The parameter passed to stored procedure is the year and it is used for pivot. The statement looks like this:
@sql = 'SELECT * FROM (SELECT YearId, SchoolId, ReportText, OutputValue_Text from AggregateTable) AS AGAM
PIVOT (MIN(OutputValue_Text) FOR YearId IN ([' + @YearId + '])) PVT'
EXEC(@sql)
So, since the years passed as parameters can change, I cannot hard-code it as column in my report, so I need to programatically display column names and values from my dataset, something like dataSet.Tables[0].Columns[].ColumnName; I have tried with writing the code, but I do not have much experience with it and I have not been very successful. Can someone help me with the code?
Thanks

Hi,
I have two servers, namely ServerA and ServerB. These two servers are on the same subnet. ServerB has a database called DatabaseB.
I'm logged in in ServerA and trying to pull data from DatabaseB.
This is the query I do when I'm logged in in ServerB (note im using Microsoft SQL Server Management Studio):
USE DatabaseB
SELECT distinct b.Subject
FROM dbo.F_Class_Exam a
LEFT OUTER JOIN dbo.D_Course_Catalog b
ON a.Course_ID = b.Course_ID
WHERE a.Term = '2071' AND a.Class_Exam_Type = 'FIN' AND b.Term = '2071'
ORDER BY b.Subject
How would I do this same query on ServerA? Ideas? Thoughts?
Thanks,
Mikhial

While I can connect to the database, I get an errortelling me "exclusive access could not be obtained because thedatabase is in use".Does this mean the only way to run the restore is via EnterpriseManager?Thanks,Tom

Hi All,
Quick question ...
Is it possible to add an external server registration using SQL Server Management Studio Express CTP?
Reason being I have been doing some work from home and need to port the data back to the office who are on SQL 2000. I have a database with my web hosting company and wanted to export the data to the 'live' database so I could import to the office database - any ideas?
I've tried to connect using my login details and I know the live DB is operational as I can connect through my work system. I just can't seem to be able to do it on my system at home.
Any help would be greatly appreciated as it's been a real pain to get stuff transferred. I've so far had to generate SQL script to create the procs and tables for when I get to work - the proper down side is that I lose the content of the tables which not much right now but will be loads soon!
Many Thanks
--
I have just dicovered that the CTP management studio will not connect to SQL 7 - is there any alternative or does the new version compensate for this?

Ok,
I am a webdesigner who at the moment does not know SQL (although, I plan on remedying that) so I am developing a page with a DB designer - he is doing the DB work, I am doing the look/feel, but he asked me the following questions, of which I cannot seem to find an answer and the guys who tend our server are useless - so I am hoping someone here can help me. In general what he needs to know is:
"what is the external address (either in domain format or IP) and the equivalent internal address so that we can access the msSQL running on your server. The internal address is needed for the webpages to talk to it, while the external address is needed for development of the pages in visual studio and the database tools." Also, he later sent me an email asking that when I get this info (from someone) that it would be usefull to get a sample string/query to get access to the DB. I am running SQL 2000 and have enterprise manager. Where can I find this information? or how do I figure this out????
Thank you for all the help -- Please let me know if you need any more info.

MS-SQL 2005, C# 2.0
I will have many client databases that will be updated. When they are updated I need to transfer some of that data to a central Server database somewhere on the Internet. Note, schemas do not necessarily match.
Transfering the data (Web Services, Remoting) is not a problem.
What I am looking for is a cool, correct, advisable way, for the client database to notify me of an Insert, Update or Delete. I can then initiate the connection to the Server and 'push' the data (maybe pull some back from the Server too).
Obviously Triggers may be a place to start... But I need to know 'external to the database' that an update has happened or can I send the data from within the SQL Server assembly?
Anyone have any ideas or a technique, maybe something new in SQL Server 2005 (all databases will be 2005), for acheiving this? Just so I don't go down the 'wrong' path...
There are some BLOB's involved (1-2 page PDF's), if that makes a difference.
I envisage that the process transfering the data will be a Windows Service running on each client. The connection may not always be available, so some kind of 'to do' list of outstanding data to be transfered is required.
I'm just starting on this, so any pointers would be great, I'm sure it's all been done before ;)
Thanks
Rob.

Please excuse what is probably a no-brainer, but here goes.Is there any difference, in terms of performance or any other pertinentfactor, between:SELECT * FROM tblCustomers INNER JOIN tblCustomerOrders ONtblCustomers.fldCustomerID = tblCustomerOrders.fldCustomerIDandSELECT * FROM tblCustomers, tblCustomerOrders WHEREtblCustomers.fldCustomerID = tblCustomerOrders.fldCustomerIDI note that if I type the latter into the SQL pane in a Data window,SQL Server replaces it with the former.TIAEdward--The reading group's reading group:http://www.bookgroup.org.uk

I'm trying to use merge data from a staging table to a production table. There are a lot of duplicate values for serverName and I only want to insert one instance where there are duplicates.
How I can adapt the code I have so far to achieve this?
MERGE tblServer AS TARGET
USING tblTemp AS SOURCE
ON (TARGET.serverName = SOURCE.serverName)
WHEN MATCHED THEN
UPDATE SET TARGET.serverName = SOURCE.serverName, TARGET.serverLocation = SOURCE.serverLocation
WHEN NOT MATCHED BY TARGET THEN
INSERT (serverName, serverLocation)
VALUES (SOURCE.serverName, SOURCE.serverLocation)
WHEN NOT MATCHED BY SOURCE THEN
DELETE;
