Converting Data From Access 2000 To SQL Server 2000
Oct 18, 2004
Hi,
I worked on a project in ASP.NET using SQL server 2000 as the back end. Its a conversion application that I rewrote in ASP.NET using C#. I need to import the old data in Access db into SQL server 2000 and I have very little knowledge about doing it. The data in not a direct one -one transformation. There are considerable changes to the Database design and data types. Any help and suggestions wud be really helpful. Also, any article links wud be great.
I have a large (huge) database that I want to copy onto my new slq 2005 test server. I'm leaning toward detaching the data on my 2000 box, duplicating it, copying it to my new 2005 machine, and attaching it. Is it possible that it could be that simple? If not, how is it done? Thanks a bunch for any help or pointers to the articles I was totally unable to find on the subject.
Hi,Simple question: A customer has an application using Access 2000frontend and SQL Server 2000 backend. Data connection is over ODBC.There are almost 250 concurrent users and is growing. Have theysqueezed everything out of Access? Should the move to a VB.Net frontendtaken place ages ago?CheersMike
I've created a small company database where the tables reside in a SQLServer database. I'm using Access 2000 forms for a front end.I've got a System DSN set-up to SQL Server and am using links withinAccess 2000 to get to the SQL Server tables.My forms worked fine until I made a few minor changes to the databaseschema on SQL Server (e.g. added a foreign key, or added a column).After that, all the links break - I click on a table link and get anerror msg like "invalid object name."Deleting the links after a schema change and re-adding the links seemedto fix the problem. The forms I'd already created seemed to work fineafter re-creating the links.But then I got more advanced with my forms. I have it set up so thatfor certain entry fields, the combobox gets populated with values froma table (the description appears in the drop-down and the correspondingprimary key value gets populated in the table). I created a number offorms using this technique, entered data, and everything worked fine.Made a small schema change and it broke everything -- not the actualtable links, but the functionality for the drop-downs. My values nolonger appeared, and this was true for forms that accessed tables whoseschemas did not change.This is driving me nuts. Is there any way to keep my forms frombreaking each time I make a small schema change?Thanks.- Dana
We have a SQL Server 7.0 system in NT 4.0 environment. We upgraded our users to Access 2000 and started to work with this. Now we installed a new server which is Windows 2000 based and the domain is different from the SQL servers domain. We then installed Access 2000 on Windows 2000 to use with terminal server. But I noticed that there was a problem with the program. I then looked at the program which was written on Access 2000 and saw that the tables and views can't be seen. The program runs but I can't see the views and tables. Another thing is access disconects from SQL Server when I want to see the tables. So what can be the problem.
In one part there is an Access 2000 on Windows 2000 server. On the other part SQL Server 7.0 on Windows NT 4.0. And Access can't see the tables in SQL server.
I am converting a MS Access 2000 project to use SQL Server. This project has uncovered a number of problems, my latest seems to be very odd.
When I query using ADO against the SQL Server database, the results don't seemed to be returned immediately. It's like the access methods being used are waiting too long to write/read the data.
This could be a simple ADO configuration error, but I cannot find any settings that would make this behave so strange.
I'm using OLE/DB drivers with trusted security and attaching using client-side recordsets (I tried server-side as well, same results) to get data for the Access form. In many instances, the data from the form is not yet retrieved when I check the results using the debugger. If I execute the same section of code just seconds later, it works without fail.
I ran the SQL Server Profiler just for grins and found that records were not getting written to the database as I would have expected. Apparently ADO had generated a transaction and rolled it back. (why I don't know) I have looked in Microsoft's support database and on MSDN to no avail. Rather then rewriting my T-SQL as stored procedures for these functions, I'm hoping for some insights from anyone else who has been down this nasty road.
Here is the exact scenario:
Problem #1: A form that accepts data and has an update button does not update the recordset being used to populate the form. I even coded a rst.Update statement into the code. The record within the recordset isn't updated until the DoCmd.GotoRecord , , acNewRec call has been made. I suppose I could code the insert statement myself, but shouldn't Access be updating the database for me. (it does have r/w access)
Problem #2: A subform that performs a query and allows records to be added to a table does not correctly detect data returned from the query. A check is made in the code for a field (which has a value of 0) but the code detects a null value. If I step through this code in the debugger, enough time passes that the value is present and I never see the problem. If I set a breakpoint at the error, the null condition is indicated, even though the debugger shows a value of 0 for the field.
SQL Server version is 2000, with SP3a applied.
I updated the MDAC to 2.8, JET to 8.0 and still the same problem. I cannot find anything in my ADO or Access books for a setting that would cause this behavior. My connection is using the following info:
Set Conn = New ADODB.Connection Conn.CursorLocation = adUseClient Set rst = New ADODB.Recordset Connection string: Provider=SQLOLEDB;Data Source=myserver;Initial Catalog=mydb;Trusted_Connection=Yes;Integrated Security=SSPI; Recordset Cursor type: adOpenDynamic Recordset LockType: adLockOptimistic
I open the recordset using: rst.Open mytable, Conn, adOpenDynamic, adLockOptimistic, adCmdTableDirect
Problem # 1
After manipulating the data in the form, I press a "save" button on the form. This button calls a number of subroutines, eventually executing the code below:
Problem # 2 I set the recordsource using: (in the form_open) Me.RecordSource = "Select * from mytable where myfield = 'data'"
In the form_unload, the problems occur. It tests for a value stored in the form from the query. This value is null at the time of the code execution, it has a value when inspected within the debugger however.
Maybe I'm missing something here, this project was originally coded using DAO. My conversion to ADO is 95% complete. (all of these two components are converted to ADO) This problem is causing me to miss out on sleep and look like a rookie.
Has anyone seen or heard of something such as this? Is there any hope for this snarled mess of 25K lines of code?
Hi,I have developed an application using VB 6 (SP 5), MS Access 2000 andCrystal Reports 9. I migrated from from access to SQl Server 2000.This wasn't a problem as i could import all the tables to SQL Server.Also, i could make VB6 talk to SQl Server.The problem arsies when i run my application. The sql syntax foraccess seems to be different than that for SQL Server. A simpleexample being: In access boolean datatype is true/false ,whereas inSQL Server the boolean equivalent is bit (numerical 1 or 0). Thesekind of issues are causing problems and most queries don't run.Would i need to go and change all the queries in accordance with SQlServer syntax ,which would be very time consuming or is there anyfunction which will convert the access datatype into its equivalentSQl Server datatype??Any input/thoughts/suggestions would be appreciated.ThanksJatin
hi All, I tried following piece of code in SQL 2005 , is working fine. Select * from Table FOR XML RAW('RECORDS')ELEMENTS,ROOT('MyTable'). But when i tried the same thing in SQL 2000 , it was not working . Plz suggest a way in 2000 to get the XML output with custom RootNode Name in 2000 also like in 2005 ? Thanks in advance. Mohit
We are experiencing a problem with Sql Server 2000 linking to anAccess 97 file. We have two machines that link to this .mdb file, andwe recently upgraded one to newer hardware, SP3a, MDAC 2.8, etc. Thelink on this upgraded machine no longer works, giving this message:Server: Msg 7399, Level 16, State 1, Line 1OLE DB provider 'Microsoft.Jet.OLEDB.4.0' reported an error.[OLE/DB provider returned message: Cannot open a database created witha previous version of your application.]OLE DB error trace [OLE/DB Provider 'Microsoft.Jet.OLEDB.4.0'IDBInitialize::Initialize returned 0x80004005: ].The link on the older machine still works. We decided to tryconverting a copy of the file to Access 2000 to see if the newerpatches/drivers/whatever no longer supported 97. We set up a link onboth machines to this file, and they both work. However, on theupgraded machine, the following error is receievedServer: Msg 7399, Level 16, State 1, Line 1OLE DB provider 'Microsoft.Jet.OLEDB.4.0' reported an error.[OLE/DB provider returned message: System resource exceeded.]OLE DB error trace [OLE/DB Provider 'Microsoft.Jet.OLEDB.4.0'ICommandText::Execute returned 0x80004005: ].when making 1-3 connections to the the linked server, while the oldermachine supports at least 7 simultaneous queries connecting to thelinked server and still hasn't produced that error.Does anyone have any idea if there is a known issue with linking toAccess 97/2000 files under MDAC 2.8, Jet 4.0, etc? Any light anyonecan shine on this subject would be greatly appreciated.
I am getting the error message as "DIAG [00000] [ODBC Access Driver 52.1.150.0] -26 Driver not capable (-26)" at the time of retrieving the catalog infromation by SqlTables methode. it is shown "?" as catalogname but this not supported by odbc access driver. can you please help out how can i resolve using C++ code in SqlTables methode.
Hi, I am trying to edit some data from a SQL2000-datasource in ASP.NET 2.0 and have a problem with a column that has bit-data and is used for selection. SQL2005 works fine when declaring <SelectParameters> <asp:Parameter DefaultValue="TRUE" Name="APL" Type="boolean" /> </SelectParameters>When running this code with SQL2000, there are no error-msgs, but after editing a record the "APL"-column looses its value of 1 and is set to 0. Looks like an issue with type-conversion, we've hit incompatibilities between SQL200 and 2005 with bit/boolean several times before. So, how is this done correctly with SQL2000? (I've tried setting the Type to "int16" -> err. Also setting Defval="1" gave an err) ThanksMichael
Hi.. I want to convert .dbf files to sql server 2000 tables.. without using any tools. I need to create a different structure for sql server tables other than contains in the .dbf files. May be the dbf files contain only 3 columns. but i need 5 columns and some calculations to determine the values of some fields to insert into sql server table... i need to code this using c# in asp.net.. can u help me? thanks in advance.. Fraijo
OK, I have some SQL Server 2000 databases that I want to convert to 2005. My question: how do I do that? I tried importing the data, but it only picked up 3 tables out of 7 user tables in one of my SS2K databases. Plus, it did not pick up any stored procedures or any other kind of objects. So I tried restoring from a backup, but predictably it could not do that because the original backup was on a different server. I also tried the upgrade advisor utility that comes with SS2K5, but it could not seem to connect to my SS2K server -- it said it could not find any SQL Server objects on the server, even though I am connected using Enterprise Manager and have been using this server for a long time. Is it looking for 2005 databases? That wouldn't make a lot of sense. Anyway, I am stumped... can anyone provide help on this? Thanks!
I am struggling rewriting my query from MS Access' IIF, Then to SQLServers TSQL language. I am hoping some one can give me someguidance. I believe I have the first portion of the query correct butdo believe this requires a "NESTED" argument. This is where I amlost.My Original MS ACCESS Query reads--SELECT DISTINCTROW REGION_TRAFIC.*,IIf(Mid([SWITCH CLLI],5,2)=[TERM STATE],IIf([CARRIER]="VENDOR4",[DOMESTIC LD RATES]![INTRA_VENDOR4],IIf([CARRIER]="VENDOR3",[DOMESTIC LD RATES]![INTRA_VENDOR3],IIf([CARRIER]="VENDOR2",[DOMESTIC LD RATES]![INTRA_VENDOR2],IIf([Carrier]="VENDOR1",[DOMESTIC LDRATES]![INTRA_VENDOR1])))),IIf([CARRIER]="VENDOR4",[DOMESTIC LD RATES]![INTER_VENDOR4],IIf([CARRIER]="VENDOR3",[DOMESTIC LD RATES]![INTER_VENDOR3],IIf([CARRIER]="VENDOR2",[DOMESTIC LD RATES]![INTER_VENDOR2],IIf([Carrier]="VENDOR1",[DOMESTIC LDRATES]![INTER_VENDOR1]))))) AS CPM,[CPM]*[MOU] AS COSTINTO INTRALATA_LDFROM REGION_TRAFIC LEFT JOIN [DOMESTIC LD RATES] ONREGION_TRAFIC.RATEKEY = [DOMESTIC LD RATES].RATEKEYWHERE (((REGION_TRAFIC.[TERM LATA])=[REGION_TRAFIC]![LATA]))ORDER BY REGION_TRAFIC.[TERM LATA] DESC;I have tried to re-write this in SQL SERVER as --SELET DISTINCT REGION TRAFIC.*,CASEWHEN [CARRIER]="VENDOR4" THEN [DOMESTIC LDRATES].INTRA_VENDOR4WHEN [CARRIER]="VENDOR3" THEN [DOMESTIC LDRATES].INTRA_VENDOR3WHEN [CARRIER]="VENDOR2" THEN [DOMESTIC LDRATES].INTRA_VENDOR2WHEN [CARRIER]="VENDOR1" THEN [DOMESTIC LDRATES].INTRA_VENDOR1ELSEWHEN [CARRIER]="VENDOR4" THEN [DOMESTIC LDRATES].INTER_VENDOR4WHEN [CARRIER]="VENDOR3" THEN [DOMESTIC LDRATES].INTER_VENDOR3WHEN [CARRIER]="VENDOR2" THEN [DOMESTIC LDRATES].INTER_VENDOR2WHEN [CARRIER]="VENDOR1" THEN [DOMESTIC LDRATES].INTER_VENDOR1ENDAS CPMCPM*MOU AS COSTINTO INTRALATA_LDFROM REGION_TRAFIC LEFT JOIN [DOMESTIC LD RATES] ONREGION_TRAFIC.RATEKEY = [DOMESTIC LD RATES].RATEKEYWHERE (((REGION_TRAFIC.[TERM LATA])=[REGION_TRAFIC]![LATA]))ORDER BY REGION_TRAFIC.[TERM LATA] DESCMy challenge is the Case portion of the query and the nesting!

Hello, I have the following query in Access 2000 that I need to convertto SQL 2000:UPDATE tblShoes, tblBoxesSET tblShoes.Laces1 = NullWHERE (((tblShoes.ShoesID)=Int([tblBoxes].[ShoesID])) AND((tblBoxes.Code8)="A" Or (tblBoxes.Code8)="B"))WITH OWNERACCESS OPTION;The ShoesID in the tblShoes table is an autonumber, however the recordsin the tblBoxes have the ShoesID converted to text.This query runs ok in Access, but when I try to run it in the SQLServer 2000 Query Analizer I get errors because of the comma in the"UPDATE tblShoes, tblBoxes" part. I only need to update the tblShoesfield named Laces1 to NULL for every record matching the ones in thetblBoxes that are marked with an "A" or an "B" in the tblBoxes.Code8field.Any help would be greatly appreciated.JR
I recently had to reinstall a new instance of SQLServer 2000, but was unable to use the previous server name. As a result, my Access2000 front end is not happy with it's linked tables. I can't seem to find anyplace within Access to universally change the address of the SQLServer used as the back-end for all linked tables.
When I do try to access the linked tables through Access, I get an error, and the option to change the server location. When I try to type-in the new SQLServer location, there is an attempt to reconnect to SQLServer, but a whole lot of errors are generated, and none of the data is transferred into the Access table.
I really don't want to have to re-do my Access front end, so it seems it would be easiest to somehow reinstall SQLServer to have the same server location it used to. Is there a good way to completely erase all traces of SQLServer so that I can have better luck reinstalling it to the same location it used to be in? Just using the uninstall program from SQLServer doesn't seem to be cutting it.
We are using an Access 2000 project to view our SQL Tables and using Access 2000 Runtime to Access the forms in the project. We have written in a locking system in VB and removed the video controls to prevent users from accessing the same records. But of course now we need to make the video controls available. This has now thrown up the problem of multiple users accessing the same records. We have tried to write code to lock records when then video controls are used but this is not working as well as we hoped. Can anyone please suggest any way of setting up locking on SQL using triggers from the Access frontend? or any other types of locking systems that could be written in the Access front end.
When I try to make a connection to an Access .mdb I get the following error: "Unable to open application. The workgroup information file is missing or opened exclusively by another user"
Yet, I am able to open the file through Access and have necessary permissions and I know no one else has it opened. The mdb is password protected and I have provided the correct login information in the DTS connection.

Hi, i need some help, i have a problem trying to access data in my local network.
I have a PC with ms windows server 2003 and ms sql server 2000, and i want that the others PC in the network can access the data. I installed the client sql server in the others PC, but i can't make it work. What i have to do?
when i try to import data from Microsot Access to Microsoft OLDB DB Provider in the "DTS Import/Export wizard", an error occurs: Error Description: [DBNETLIB][ConectionOpen (Connect()).] SQL Server doesnt exist or the access was denied. I'm using windows autentication and the data base of destination is <default>.
Hi everyone, Well, it's a bit difficult to explain this issue. I have written an e-commerce asp.net web site the web site will be hosted on a regular web host that i bought from a hosting company. and we have 2 servers in our company which one of them has internal ip address and the other one has fixed ip address. I have to install my sql 2000 db on the first server(the one with internal ip), I wanted to know that how can I link the the data base to the website via the second server(the one with fixed ip address). I was thinking about using link servers in sql server.... Could any one told me that if it is a good idea or not????
To begin with, I aplogize for not posting a pure SQL Server question in this forum. I thought some of you might be able to help me out.
I have an Access application (both front and back ends built in Microsoft Access). I don't have the source code which has access forms and the VB code. All I have is an .mde (Access executable) and .mdb (Access database) that carries the actual data. All the forms in .mde are linked to data in this .mdb
We are planning to convert the whole thing into ASP & SQL Server, but before it gets ready, we want to change the back end to SQL Server leaving the front-end App in Access. My plan is to make all the tables in my MDB to linked tables that point to SQL Server. But since my .mde already has linked tables pointing to the access tables in MDB, it is not allowing me to have a linked table pointing to another linked table.
Can anyone let me know if there is any workaround to achieve this? Your help will be very much appreciated.
I am linking to an SQL table through an access database. I need to add records to the SQL table through the Acess .mdb but the linked table will not let me. How can I fix this? Any help is appreciated. Kelley
hi, somebody asked me this question but I haven't succeeded to give a good answer... The question was... Access 2000 is a DBMS and Sql server is an RDBMS,so what makes sql server a RDBMS in context of Codd's rule?What are the properties that Access doesn't have to be a RDBMS? May be this is not so important issue,if anybody wants to answer plz help,gurus are requested not to waste their valuable time....If any of the gurus come I would be delighted....:D
