ODBC, ADP, Or Simply The VB Route.
Jun 8, 2004
Hello All,
I have an application running off an Access database. Im trying to convert the application to a server-client architecture and thus moving everything to SQL Server 2000.
I have read alot of articles about ways to accomplish that but I've still yet to decide on which approach is the best (best as in robust and scalable).
I pretty much eliminated the ODBC route due to all the layers of translation a request has to go through to reach SQL Server, although this route seems to be the quickes to accomplish.
Mind you I have plenty of time on hand and am willing to re-write the whole thing from scratch if it means a better app.
Now should I go the ADP route and keep Access as the user interface or should I rebuild the whole front End in pure Visual Basic that interacts with SQL Server? Im leaning towards the latter solution.
I haven't read any articles talking about rebuilding the whole app. using VB and SQL Server instead of just using ADP. Why so and which solution do you think is a better solution for a client-server architecture??
Thanks in advance for any replies to my questions.

Hi,
I am trying to generate scripts for route optimization, that is in what order a machine should operate on different sites with lowest cost of transportation.
I alreday have generated the matrix with distances between all sites.
And the problem now is how to generate the lists of all possible routes.
That is all possible combinations of in which order the sites can be operated.
Does anyone have a clue?
Thank you in advance

Hi
I have a very simple and probably stupid question. I am new to SB. My question is when I create a service and queue do I have to create a route always?. whats the purpose of creating a route?. what happens if i dont create a route. As I understand creating a route creates a routing table in the database but i am perplexed as to what is the actual use of this routing table and in what way it helps.
Thanks
AK

I am using the TRANSPORT and self-routing and it works great. My question is: is there ever a need for more than one transport route when using multiple services, or should there just be one per database, generally speaking? What exactly does the presence of this route tell service broker? It seems as though it just signals service broker to use self-routing if it can't resolve the service any other way....similar to the way the LOCAL route works, only for remote services.

I have two databases (A and B )on the same SQL Server instance. Both have SSB enabled and running fine within themselves. All athorizations are at present set to dbo.
Recently I had a requirement to start a dialog and send a message from within data base A to a queue via a service that is in database B.
I tried coding the SSB instance in the BEGIN DIALOG then I set up a route and tried that. On both occoasions I got the following on sys.transmission_queue
"An exception occurred while enqueueing a message in the target queue. Error: 916, State: 3. The server principal "sa" is not able to access the database "B" under the current security context."
Is this sometjhing to do with security lock downs in 2005?

Hi Remus,
I am experiencing the same problem, and I can't get the easy fix to work. I drop and create the DB's in between tests, so it is not related to having an old certificate in the DB, as in the case of Tilfried.
The situation is as follows:
DB1 owned by login1, has a user for login2; this DB is for the initiator
DB2 owned by login2, has a user for login1; this DB hosts the target
Both DB's have TRUSTWORTHY flag set to ON
Error in sys.transmission_queue: 'Error 916, State 3: The server principal "Login1" is not able to access the database "DB2" under the current security context.
Going on a limp, I decide to add a remote service binding in DB1, binding the user for Login2 to the target service, even though BOL explicitly states that this is only required for cross-server communications. This does change the situation - I still get an error, but a new message is sys.transmission_queue: "Dialog security is unavailable for this covnersation because there is no certificate bound to the database principal (Id: 5). Either create a certificate for the principal, or specify ENCRYPTION = OFF when beginning the conversation." I already know that the first option works, but I wanted to get the simple solution running. As for the second option, I doublechecked and the initiating procedure DOES already specify ENCRYPTION = OFF in the BEGIN DIALOG CONVERSATION command. My theory is that the remote service binding somehow forces SB to use encryption, but (a) that is not stated in the error message, and (b) if so, then how to get the messages sent over to the target service without using the binding?
==> EDIT: Just saw that you confirmed this theory in your last reply to Tlifried. So I am indeed back to having to find out how to get this to work without remote service binding - it should be possible, but how???
BTW, SELECT @@VERSION shows that I'm on build 3054, in case it matters.
Between all the errors in BOL and less than helpfull error messages produced by SB, I feel like I'm slowly losing my sanity. Please help!
Best regards,
Hugo Kornelis

Hi all,
I would like to simply link two tables that are in two different databases in the SAME server.
I know that I could use the replication method (snapshot or merge) but I need a simpler method like the Access link table method.
Any suggestions?
Thanks

Hello all,
I need some help in simplyfying the following update statement -
update table <table_a> set <col_1> = NULL where <col_1> = 'N/A'
update table <table_a> set <col_2> = NULL where <col_2> = 'N/A'
update table <table_a> set <col_3> = NULL where <col_3> = 'N/A'
update table <table_a> set <col_4> = NULL where <col_4> = 'N/A'
update table <table_a> set <col_5> = NULL where <col_5> = 'N/A'
update table <table_a> set <col_6> = NULL where <col_6> = 'N/A'
update table <table_a> set <col_7> = NULL where <col_7> = 'N/A'
....and there are 73 columns
Anyway I can create a loop or array and store the column name as a parameter and then pass it to the update statement?
Thanks in advance,
Saurav

I'm just getting started with SSIS and need pointing in the right direction with my first attempt to create a simple transform lookup.
The objective is to copy some columns from a table in one SQL Server 2005 db into another table in a different db on the same server. There are some simple column transforms involved but one column in the target table needs populating from a lookup as a result of a SQL Query.
So far, I have one OLE DB Source object linked to one OLE DB Destination in 'Data Flow'. I've configured the column transforms and these appear ok. However, the problem is that I can't see how to setup the Lookup. I have added a lookup transform object to the Data Flow space, linked from the appropriate OLE DB Source. The simple sql query returns the correct value when previewed. If I try to connect the output of this lookup object with the same OLE DB Destination that is the output from the first column transform, I get a warning message : -
"Cannot create connector. The destination component does not have any available inputs for use in creating a path"
There is column in the destination table available but I don't know how to direct the lookup output to it. I can see this available column by looking at the OLE Destination object properties and clicking 'Mappings'. The other columns are showing the links in the transformation with the destination column intended for the lookup output is not showing any links.
How do I linkup the output from the lookup object to the OLE Destination object? Is it ok to have two inputs into the OLE Destination object (ie. 1. the output from the OLE DB Source; and 2. The output from the lookup object)?
Thanks in advance,
Clive

I am developing a asp.net app and I have a long, very long list of data fields.
The values of the data fields have to be saved to a SQL database. The list is so long that it a pain in the ass to have to write all the code even to declare an object and all its properties by hand. So...
I made a list of all the field names and types and load it all up in an array. Then I wrote a bunch of macros to write all the properties one by one with the corredt type for the object I needed to create instead of doing it all one by one by hand.
I want to do the same thing with the Database. I dont want to have to hand define all the fiedls 1 by 1 by hand in the IDE. I want to write a simple macro, a loop theat loops thru my array and creates a field with the field name and type that it says in the array.
Simple enough.. Now I have the table defined already since that was simple enough. It is the 200 ++ fields that I dont wanna do.
So, please what is the code I need (in VB) to create 1 simple field in an existing table. Say the table is called "Table1" in the database "Database1" and the field I want is to be called "Field1" and to be 250 chr string..... ???
Thank you Marc

Hi.
A newbie question. I am tearing my hair out trying to work out how in Sql Server 2005 to get a printout (or even better a file I can save that i could incroporate in a wrod document), or both, which shows the structure of all the tables in my database.
I want to list all tables (or selected tables perhaps) , and all columns in those tables, with the attributes of each column (nvarchar(2) etc or decimal(18,5) etc). Just a simple listing of all tables and their columns and the attributes of those columns.
Surely this must be possible with a simple one click operation in Sql Server 2005. I have created a database diagram which gives me part of what I want, but that just shows the tables, relationships, and column names, not the attributes of each column which is what I need as well.
I don't want to have to start installing third party products to do this, and I have no great script writing capabilities. Surely such a basic function is easily acheivable with one or two clicks in Sql Server 2005 from a menu somewhere in sql server mangaement studio?
Thanks in Advance for your help.

Advanced setting options for flatfiles were tried, but didn't work.
For solving this problem i am also using Script Component for column 58.
I am also geting more then 60 warnings of truncation

Hi,
I am using VB.NET 2005 and set up an ODBC connection via ODBC.ODBCConnection to a MDB database. Therefor, I use the "Microsoft Access ODBC Driver (*.mdb)".
When I set up a ODBCCommand like "ALTER DATABASE..." or "CREATE TABLE..." and issue it with the com.ExecuteNonQuery() command, I get an error from ODBC driver, that a SQL statement has to begin with SELECT, INSERT, UPDATE or DELETE.
How can I use DDL statements via ODBC?
I would appreciate if you could help me to use ODBC for that - no OLE, no ADO.
Thanks for help!

I apologize if this is not the correct forum for this posting. Looking at the descriptions, it appeared to be the best choice.
I am running Windows XP Pro SP2. I have installed the SQL Native Client for
XP. However, when I try to add a new data source through ODBC Connection
Manager, SQL Native Client is not listed as an option. I have followed this procedure on three other systems with no problems. What would be causing the
SQL Native Client to not show up in the list of available ODBC data sources?

Hi all,I am having trouble getting linked Oracle 9 server in MS SQL Server2005 Express to work properly. My machine is running Windows XP.The Microsoft and Oracle OLE DB Providers have problems dealing withOracle's Numeric Data Type, so I decided to use Microsoft's OLE DB forODBC Provider and an Oracle ODBC source. When using the Microsoft ODBCfor Oracle Driver in my ODBC source I have inconsistent behavior.Sometimes my queries are processed properly, then other times I get thefollowing errorOLE DB provider "MSDASQL" for linked server "ODBCBEAST" returnedmessage "[Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttrfailed".OLE DB provider "MSDASQL" for linked server "ODBCBEAST" returnedmessage "[Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttrfailed".OLE DB provider "MSDASQL" for linked server "ODBCBEAST" returnedmessage "[Microsoft][ODBC driver for Oracle][Oracle]".Msg 7303, Level 16, State 1, Line 1Cannot initialize the data source object of OLE DB provider "MSDASQL"for linked server "ODBCBEAST".I have no idea why sometimes I can connect to the linked server with noproblems andwhy other times it performs like this. I'm not changing anything aboutthe system I can think of. When I use an Oracle client (PL/SQL) I haveabsolutely no problems connecting. TNSPING returns that the connectionis good.This is unacceptable so I decided to try my luck with the Oracle 10gODBC driver. However when I use this and perform an openquery selectagainst the linked server I get back only 11 rows, when I know that thedatabase has over 100 rows (in fact when using the Microsoft ODBCdriver and it works that's what I get). I figured maybe the buffersetting needed to be raised in the ODBC configuration so I took it from64000 to 600000 (a magnitude of 10) but I still get back only 11 rows.I'm at my wit's end.Any suggestions on resolving one or the other problem would be muchappreciated.Thanks much

Hi,
Please help share with me if you know the version compatibility matrix of Ms SQL Server, ODBC driver (sqlsrv32.dll), Driver Manager (odbc32.dll) and ODBC API spec. For instance, how can I know Ms SQL Server 2000 can work with which version of sqlsrv32.dll, a particular version of sqlsrv32.dll can work with which version of odbc32.dll and a certain version of sqlsrv32.dll/odbc32.dll conforms to which version of ODBC API spec (e.g. 3.5).
Any help will be appreciated.

HeyI have developed a asp.net 2 system on my local machine using a local sql2000 server.Now i'm trying to deploy it to a windows 2003 server, using a sql2000 server on another windows 2003 server. I thought the only thing i had to do was to create a ODBC connection to the sql server, and change the connectionstring. But no :)
What kind of changes do i need to do. Do i need to change the dataprovider.
I get this error:
An error has occurred while establishing a connection to the server. When connecting to sql Server 2005, this failure may be caused by the fact that under the default settings sql Server does not allow remote connections. (Provider: Named Pipes Provider, error: 40 - Could not open a connection to sql server)
But i don't use a sql 2005 server.
Pleace help :)
