How To Update A Table From A Link
Jan 16, 2007
I need to append data to the existing Table1 from a .txt file stored in a link e.g. "http://xx00xx0123.abcdef.net/ABC_REPORTS/DATA/Table1.csv"
(Columns in both tables are identical)
This .csv contains a rolling 7 days of stats. which means if it is added every Morning 6 of those Days will have been added before and must be Deleted.
I would like to schedule an automatic procedure to create a temp table in the server every day and a script removing duplicates.
I have a few questions:
*) Can I shedule from the Enterprise Console to read/create table from the above link to do this?
**) I heard I need an SQL agent. If so why and what is it?
***) Is it better to append data and then script removing Duplicates, or is it better to import into a temp table run comparison between the 2, Delete from Temp what is Common and then append whats left of the Temp to the Table1?
****) Please could someone paste a sample of CREATE TABLE from a http link like the one above?
Thanks for your help,
Gezza

When trying to link to an SQL table in Access 2003, the software appears to be malfunctioning.
The sequence of events is File - Get External Data - Link Tables - Files of Type: ODBC Databases().
The Problem: On two of my computers, the select data source window does not pop up, preventing me from linking to any ODBC data source.
Observations: This function has worked normally in the recent past and works on other computers running Access 2003. One difference between the computers working and non-working computers is Norton Antivirus 2006 (recent upgrade).
Has anyone experienced anything like this? What's going on?

Hi Folks,
Somehow i am stuck at a very basic step. I have two pages -
1. DomainList.aspx which just displays all the records from the Domains table.2. DomainAddEdit.aspx which displays the selected record in FormView(Edit Mode) with two link for Update and Cancel.
The Update link in the FormView does nothing on the first click. It just reloads the page with the new data I entered. If I click again on the Update link, it throws me an error:
"Cannot insert the value NULL into column 'DNS', table 'MSInteractive.dbo.Domains'; column does not allow nulls. UPDATE fails.The statement has been terminated. "
I have no clue why all this is happening. I have spent more than two days on this and this is very very frustrating.
Just to mention, I haven't written any code for this. Its developed all using the VWD tools available. I have posted this message earlier but haven't got any response. I am sure most of you guys must have been doing these steps everyday. So, please post your thoughts.
Thanks a million.
Here is the relevant code for my DomainADDEdit.aspx:
<asp:FormView ID="FormView1" runat="server" DataSourceID="SqlDataSource1" DefaultMode="Edit"> <EditItemTemplate> Id: <asp:TextBox ID="IdTextBox" runat="server" Text='<%# Bind("Id") %>'></asp:TextBox><br /> RegistrarAccountId: <asp:TextBox ID="RegistrarAccountIdTextBox" runat="server" Text='<%# Bind("RegistrarAccountId") %>'></asp:TextBox><br /> Registrar: <asp:TextBox ID="RegistrarTextBox" runat="server" Text='<%# Bind("Registrar") %>'></asp:TextBox><br /> DNS: <asp:TextBox ID="DNSTextBox" runat="server" AutoPostBack="True" OnTextChanged="DNSTextBox_TextChanged" Text='<%# Bind("DNS") %>'></asp:TextBox><br /> EmailHost: <asp:TextBox ID="EmailHostTextBox" runat="server" Text='<%# Bind("EmailHost") %>'></asp:TextBox><br /> Registered: <asp:TextBox ID="RegisteredTextBox" runat="server" Text='<%# Bind("Registered") %>'></asp:TextBox><br /> Expires: <asp:TextBox ID="ExpiresTextBox" runat="server" Text='<%# Bind("Expires") %>'></asp:TextBox><br /> MsiResponsible: <asp:CheckBox ID="MsiResponsibleCheckBox" runat="server" Checked='<%# Bind("MsiResponsible") %>' /> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:MSInteractiveConnectionString %>" SelectCommand="SELECT [Id], [RegistrarAccountId], [Registrar], [DNS], [EmailHost], [Registered], [Expires], [MsiResponsible] FROM [Domains] WHERE ([Id] = @Id)" UpdateCommand="UPDATE Domains SET DNS = @txtDNS WHERE (Id = @Id)"> <UpdateParameters> <asp:FormParameter FormField="DNSTextBox" Name="txtDNS" /> <asp:QueryStringParameter Name="Id" QueryStringField="Id" /> </UpdateParameters> <SelectParameters> <asp:QueryStringParameter Name="Id" QueryStringField="Id" Type="String" /> </SelectParameters> </asp:SqlDataSource><br /> <asp:LinkButton ID="UpdateButton" runat="server" CommandName="Update" Text="Update" OnClick="UpdateButton_Click"></asp:LinkButton> <asp:LinkButton ID="UpdateCancelButton" runat="server" CausesValidation="False" CommandName="Cancel" Text="Cancel"></asp:LinkButton> </EditItemTemplate>

we are running SQL7.0. I execute a store procedure on Server A that insert a data into the table on Server B. I use a Link Server to connect from Server A to Server B. When I execute the SP, I got the messege 'The command(s) completed successfully'. When I select from the table was inserted, I don't see the data that was inserted. Can we update or insert tabel using Link Server.
Thanks.

I have created an Access2003 project (existing data) that links to external data. First I connected to a SQL Server 2000 database. Success. Then I tried to set up a Transact SQL data connection to a legacy MDW-secured Access97 database. (A third-party VB6 application goes against it, and we don't have the source code, so we cannot upgrade it.)
The Transact SQL link tests OK but I cannot select any of the tables or queries from the list presented. However, with the same credentials, I can use these same objects in Excel 2003.
When setting up the link in Access2003, I specify JET 4.0 OLE DB Provider, I enter the MDW file on the All tab, a username and a password on the Connection tab where I browse to the MDB file, and specify Shared Deny None on the Advanced tab. When I test the connection, it tests OK ("Test connection succeeded"). Yet on the "Select the Database and Table/Cube which contains the data you want" dialog, "(Default)" appears in the grayed-out dropdown. Then, beneath that dropdown, there is a grid with Name and Description columns. The grid contains query names but the grid is not enabled. The list of queries is this table is grayed out. Neither of the scrollbars works.
BUT... if I use the SAME username and password in Excel2003, and specify the same MDW, there is no problem working with these same database objects in the legacy Access97 database. WHAT IS DIFFERENT ABOUT THE WIZARD IN EXCEL THAT ALLOWS IT TO SUCCEED AND THE WIZARD IN ACCESS THAT CAUSES IT TO FAIL HERE? In Excel, the list of available providers says Microsoft Access Driver, not JET 4.0 OLE DB Provider.
Thanks

I have used the Microsoft code below to create a link to SQL server from access. I am using DAO not ADODB. Someone said that I should use dblib instead of ODBC in the connection string below in order to get the connection to work.
Does anyone know the correct syntax for OLE DB connection string and can it be used with DAO? I am getting an error "ISAM path not found"?? Seems I have wrong connection string syntax?? Please advise.
Thanks again for your help.

Hi,
I'm looking for a possible way to access tables from SAP but in another database. This is not possible using ABAP from SAP. Therefore I wonder if it's possible to define some kind of virtual table in a database which in fact refers to a table in another MSSQL database...
Help and/or tips highly appreciated,
Paul

Tell me please how can I make a foreing key constraint for a table using from another not all primary key or not all data. For example, I need to link a table "subject" with primary key "dscp_num, depart" using depart as a foreing key. But there is no table with such primary key, there is only table "codif_values" where selecting records by condition "codif_num = 1" gives the relation with necesary primary key to link. Also I need to link "subject" table as a primary key table with the table "ses_curr". But this table doesn't include "depart" field. It includes field "reg_num" that is a primary key in table "students". This table include field "stgroup" as a foreing key for table "groups". The last table includes "speciality" field that is a foreing key for table "specialities". And only this table includes "depart" field. Tell me please how I can make a foreing key constraint for table "ses_curr" by table "subject".

Hello All,
I have a question on linking tables with SQL Server. I have SQL Server 2000 with database A on machine A. I have SQL Server 2000 with database B on machine B. I want to link tables from the database on machine A into a database on machine B. I am not quite sure how to do this - I believe this can be done as I have seen it before. Any information and or resources to direct me to would be greatly appreciated.
Thanks

Hi all,
We have lookup tables we share on 6 database servers. We keep copying these very large tables to every database we use on each server, obviously a great waste of space. We don't mind copying these tables onto each of the servers but we want to be able to link to these tables from each database from within our servers. How is this done? Thanks in advance.

Using an MS A2K front end running on WinXP and ODBC connections to SQLServer 7 on Win 2K server; there are about 10 users who access thefront end via Terminal Server and use the same front end; there areabout another 10 users who run a copy of the db on their local machine.SQL server has 2 databases, with approx. 20 tables between them (oneis for processing ckts from a remote sql server for local use, theother is a site database).There is one user that always has to refresh the same single table eachtime a release of the db is copied to his local machine. Once thetable is refreshed in link manager, the front end is good to go...untilthe the next release is made (about every 2 months--for changes inbusiness rules). We have gone and checked his WINS and DNS settingsand at this point, the only difference between other users and this onewho can't get the table normally, is that he is using a different brandmachine (he uses a toshiba satellite, all others use a ibm thinkpad).Since purchasing a new laptop for him is out of the question, doesanyone have a suggestion for correcting this problem?TIA for the help,EricO.

How can make link to a table stored in an sql express 2005 database in access 2003 ? the classic method doesen't work. i tried to use odbc databases as file type to link, then build a data source using SQL native clint driver, but in the combo for default database i don't have the database created before, only master,msdb, model, tempdb. If i try to use the attach database filename text box i receive an error "the datadase entered is not valid". Any suggestions ?

i'm pretty familiar w/ mysql, but relatively new to ms sql. Since i can do a lot more w/ ms sql, I have been trying to do all tasks in sql queries or scripts, but i'm stumped on this one. I have a table that links two things together. t1 has rows id1 and id2. When a row has these two id's, there is a "link" between them. I'm trying to make a command or script that will see if there is only 2 links for any given id.
for example, it would loop through each row, and run this command:
SELECT COUNT(*) AS Expr1
FROM links
WHERE (Id1 = this_rows_id1) OR (Id2 = this_rows_id1)
and again w/ id2
and then i would be interested in any row that only had a count of 2. is this possible?

I am designing a database schema where several tables have one-to-many relationships to records in other tables. One way to implement it is to create a link table for each pair of tables that have a relationship:
identity
Table1_ID
Table2_ID
1
12
9
2
12
15
3
18
42With the SQL 2005 support for the XML data type, there is the possibility of storing the IDs in an XML column. The XML stored with a record (equivalent to record 12 from the above example) might look like this:
<Links>
<Table2_LinkType>
<ID>9</ID>
<ID>15</ID>
</Table2_LinkType>
<Table8_LinkType>
. . .
</Table8_LinkType>
</Links>The XML column method has the advantage of not requiring that a separate table be created but does not enforce referential integrity. The link table method has the advantage of allowing constraints to enforce referential integrity but has the disadvantage of requiring the creation of a separate table for each pair of tables having a relationship and joining to an additional table has performance implications. Implementing standard Add, List and Delete operations for the link table method is straightforward. As a test and to familiarize myself with the new XML features, I created Set, List and Delete stored procedures for the XML method. Both methods will work.
In deciding which method to go with are there any other issues I should be considering besides database integrity, complexity and possible performance issues?
From the standpoint of best practices and coding standards is one method preferred over the other?
Here is some additional information. The data set I will be working with has table sizes numbering in the hundreds of thousands. Any given record will only be linked to at most a half-dozen records in any other table.
I searched on-line for information and I was able to find plenty of good articles discussing how to use the new XML data type in SQL. However, I was not able to find any information on when not to use the XML data type over equivalent joined-table methods.

Hi all,
This is a bit of a general question regarding SQL Server link tables that i hope someone can find the time to answer.
I am looking for the best practice. If I have 3 tables
1) tblCompetition
2) tblTeams
3) tblTeamsInCompetition (this is the link table)
I know the link table should have a related CompetitionID and TeamID,
but should the link table also have a primary key that is an identity
autoincrement by 1 just as you would with the other two tables. In
Access I have never done this, however in SQL Server I have read that
you should do this (but now I can't find the documentation again which
prompts me to ask the question here).
Thanks for taking the time to answer this question.

I'm a long-time Access developer who is looking to migrate his approach to SQL Server CE 3.5 instead of having all these MDBs. One thing that I do like is using Access to surf through databases; it's a lightweight way to see the data without having to fire up the overhead of Visual Studio etc. Plus there's the QBE grid for easy query design for those of us whose tool-less SQL coding is a bit rusty...
Anyway, I was wondering whether it was possible to "attach" to a SSCE database so you can see it in Access. I've tried but haven't found a way of doing it. Any thoughts? Or is this an intentional lack of capability so we have to use a more robust tool such as Management Studio or Visual Studio?
Thanks in advance!

I initially created an Access application within Access 2003 which I subsequently migrated to SQLExpress 2005 (Tables only) using Microsoft SQL Migration Assistance for Access 2003 (SSMAA) and continue to use Access 2003 as a front end, this really was easy and worked perfect. Now I added a new table to my SQLExpress DB and need to link to it from my Access application but can not find a way to do so in the same way that the SSMAA does. I need to run the Access 2003 application in share mode from multiple PC in the LAN. If I try linking to the table using an ODBC connection I can only access from the PC where the link was done! Any ideas? THanks in advance.

Hi SQL fans,I realized that I often encounter the same situation in a relationdatabase context, where I really don't know what to do. Here is anexample, where I have 2 tables as follow:__________________________________________ | PortfolioTitle|| Portfolio |+----------------------------------------++-----------------------------+ | tfolio_id (int)|| folio_id (int) |<<-PK----FK--| tfolio_idfolio (int)|| folio_name (varchar) | | tfolio_idtitle (int)|--FK----PK->>[ Titles]+-----------------------------+ | tfolio_weight(decimal(6,5)) |+-----------------------------------------+Note that I also have a "Titles" tables (hence the tfolio_idtitlelink).My problem is : When I update a portfolio, I must update all theassociated titles in it. That means that titles can be either removedfrom the portfolio (a folio does not support the title anymore), addedto it (a new title is supported by the folio) or simply updated (atitle stays in the portfolio, but has its weight changed)For example, if the portfolio #2 would contain :[ PortfolioTitle ]id | idFolio | idTitre | poids1 2 1 102 2 2 203 2 3 30and I must update the PortfolioTitle based on these values :idFolio | idTitre | poids2 2 202 3 352 4 40then I should1 ) remove the title #1 from the folio by deleting its entry in thePortfolioTitle table2 ) update the title #2 (weight from 30 to 35)3 ) add the title #4 to the folioFor now, the only way I've found to do this is delete all the entriesof the related folio (e.g.: DELETE TitrePortefeuille WHERE idFolio =2), and then insert new values for each entry based on the new givenvalues.Is there a way to better manage this by detecting which value has to beinserted/updated/deleted?And this applies to many situation :(If you need other examples, I can give you.thanks a lot!ibiza

I'm working on a report to show financial transactions from a table over a certain period. For most transactions there is a PDF document that is stored in a separate table in a binairy format. In my report I would like to include a link on every line with transaction information in the report that opens the PDF that is linked to that transaction. Just to be clear, I don't want to embed the PDF in the report but I want the users of the report to have the option to view the PDF that is related to that transaction in their standard pdf reader (adobe).
Code to do the following:
Once a user clicks on the link to view the PDF I need the code to get the binairy data of the PDF file from the table, convert it back to a PDF and open it in the default pdf reader (for example adobe reader). If it can't directly open the file then it's maybe possible to activate the 'open or download' pop up that you also get when you download something from a website.

I have a table where table row gets updated multiple times(each column will be filled) based on telephone call in data.
Initially, I have implemented after insert trigger on ROW level thinking that the whole row is inserted into table will all column values at a time. But the issue is all columns are values are not filled at once, but observed that while telephone call in data, there are multiple updates to the row (i.e multiple updates in the sense - column data in row is updated step by step),
I thought to implement after update trigger , but when it comes to the performance will be decreased for each and every hit while row update.
I need to implement after update trigger that should be fired on column level instead of Row level to improve the performance?
