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?
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
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.
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.
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:
" 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
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")
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 would like to get in the textbox all the cutomer name seperated by ",".
Is the same as I can use join(Parameters!CustomersName.Value,",") but I need to do that from the data set and not from the parameters since I don't have parameters for my customer name
I have this case where I need to multiply the value of my dataset and finally deduce one to it. For instance if I have a dataset with three values, 2, 5, 15, I need to end up with a value of 150 (2*5*15). How can I achieve this?
Hi, My server went dead(problems with the hard disk), but I have a copy of the whole sql server directory including the database in a external hard disk. I have a new server now and I would like to copy this database (with the reports from reporting services too) from the external hard disk to my new server. can anybody help me please? Thanks.
Note : I have a plain copy of all the sql server directory with all the files including the database not a SQLServer backup done with the wizards.
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);
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? How? If I can't, what are my options?Diane
I have an ssrs (report builder) with 2 dataset. the first dataset is a summary if records which the report has a column name qty and i put also a total qty summary in the last rows. the second dataset is a raw data and have a column name qty, also i put a total qty summary in the last row. The requirements is to be able to evaluate or check the total qty under dataset1 from total qty of dataset2 if equal else if not equal i have to make the font as red so that the user will inform that the total qty has a discrepancy. the users will validate from raw data which are the one items that have a missing qty. How to work on this or is this appilcable in report builder.
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.)
Hi All, I have written a stored procedure that has a return value (OUTPUT Parameter) and was wondering if there is any way to retreive this value in SQL Server Reporting Services 2005? I get the result fine, but cannot figure out how to get the return parameter.
I have a stored procedure "spDetailsByDay" which takes parameters @StartDateTime as datetime, @Day as int, @Hour as int, @Value1 as varchar(20), @value2 as varchar(20)
My report Parameters are StartDateTime as DateTime, Day as integer, Hour as integer, Value1 as string, Value2 as string, ReportType as string
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.
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?
I am new to SSIS.I am doing a left outer jon using the merge join.The output was wrong.I realised that may be we have to trim the key values.But when i do the trim in the derived column,the output of the derived columns shows that issorted is becoming false and the sort key position has become 0.So the merge join is showing error.How can i solve this error.
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?
I am getting the error Unable to open the physical file "E:Navision SqlDataForentaSQL_Data.mdf". Operating system error 5: "5(Access is denied.)". when I try to "attach" to a database located on an external hd. The database files on the external HD were copied from the original server location to the external HD. The file size is 51G+ which is why it is on the external HD. Can anyone provide me the syntax to do the sp_attach taht will allow me to send the necessary connection string: server, user, pswd etc.
I have the need to restore a database to a user's laptop on a dailybasis. This has been no problem using Enterprise Manager. I found astored procedure to run the restore and tried to call it from a visualbasic program. 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
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?
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.
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 ;)
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)
