Hello.
How can I call some functions on MSDE when working in Access (.mdb) that is
connected to MSDE via ODBC linked tables ? Especially
in-line functions, that I would like to use as recordset for my forms and
reports.
Can I call in-line functions using ADO ? I tried, but it seems that only
stored procedures are allowed (adCmdStoredProc)....
Thanks.
Problem: Have to call SPs reside in 2 SQL server DBs which will return the table information, need to merge and perform sort the result and return the final result set. this is something like wrapper SP calling other SPs asynchronoulsy.
Can this be possible in SP / SQL functions to make asynchronous calls?
If yes can you please guide me to achive this.
If no, any alternative approach, or the reason why.
I appreciate your views on this.

Dear fellow developers,
I have successfully developed a Transact-SQL stored procedure which calls a CLR function, which calls a web service. I am using a Visual Studio 2005 SQL Server Project to perform the necessary magic.
Is there a neat way to deploy this stuff to a production server?
It is bad enough deploying the sp and function, but the web server proxy also needs to be changed to refer to the production web service.
This all looks very nasty and complicated.
Am I missing something?
Hello all.
Please excuse my lack of poper terminology when describing my issue to you, as I am very new to databases.
I have set up a SQL Server database which connects via MS Access. The application works fine, except when trying to connect through VPN.
Through System DSN, I changed the server name (FSERVER) to the server IP address, and test completed successfully. I am also able to ping the server when connected via VPN. However, when I try to start the application, I receive the following error after several seconds:
ODBC-- call failed.
That's it. No other information about the error. I read somewhere to make sure the MDAC versions are the same, which they are.
As I say, I am quite new to this, but would really appreciate any guidance to help me through.
Thanks in advance!

Hello all,
I have a problem which I can't seem to understand what is the cause. Please help!!!
I have this access which run under oracle 10g. Here is the code (below) that I always get error in. When I got into this error, I go to Control Panel -> Administrative Tools-> Data Sources (ODBC) then I choose on acc (microsoft Access Driver (*.mdb)) and click Configure. I select the access and click repair. It get through and I thought that I solve the error, but every time that I close and open the access when try to run, I receive the same error again. If I goes to the same process, click repair. It work, but I have to do it every time that I close and re-open the access. Does anyone know how to make it default so that I don't have to go the same process every time. Thank you.
Run-time error '-2147467259 (80004005)':
ODBC -- call failed.

View 2 Replies View RelatedI moved a sql 2000 database to a sql 2005 server. I have a front end in access 2003. I manually created an ODBC data source system DSN using the ODBC Data Source Administrator just like it was on the other server. I can connect fine but users are saying their getting an odbc call fail. I created the connection and relinked the tables to the new server with the moved database. I completed the same task with another database and the user can connect fine. What could be the problem?
View 1 Replies View RelatedWe have this fairly simple Access database with a link table to a view in an SQL Server. The Select Query in Access is a simple select from this view with a view criteria set. Nothing fancy. What is driving is moderately crazy is that this Select Query in Access seems to work fine for months and than all of a sudden (same query performed around the same time with about the same workload on the SQL-Server) it responses with the helpful "ODBC-Call Failed" message. Closing the Access database, taking a coffee, coming back againg and try the exact same Select Query normally works, no "ODBC-Call Failed" message.
It not happens always, mosty we're fine.
When it happens it happens for all subsequent queries tried. We have to close and reopen the Access database and pray to the good Lord that it works.
We would be very interested in someone with a solution to this problem.
I am having an issue that i can't seem to resolve. By no means am I an expert with odbc connections and what not but any help would be great.
here is my issue. I have a 64 Bit terminal server that is running MS Access. I have defined my DSN within the 32 bit admin utility and it connects without a problem As soon as i try to link tables and make a connection to the database from within Access i recieve an "ODBC CALL FAILED" message.
I enabled tracing and here is what i got.....this doesn't mean anything to me but hopefully it does to someone.....

Hi All,
I have a database with primary and Unique key contraints on SQL Server 2000. I'm front ending it with Access 2k.
I want to trap the error when the Unique key constraint is hit, but i can't capture the error number. All attempts return error 0.
The error i get is
[Microsoft][ODBC SQL Server Driver][SQL Server]Violation of UNIQUE KEY constraint 'IX_lut_Referral_Source'. Cannot insert duplicate key in object 'lut_Referral_Source'. (#2627)[Microsoft][ODBC SQL Server Driver][SQL Server]The statement has been terminated. (#3621)
I've tried the soultion given here http://support.microsoft.com/kb/q185384 but now get a Type mismatch error on errStored

Hi Everyone,
I am fairly new to MS-SQL so excuse my ignorance if I have any.
I am trying to add and link a new table to an existing database. I can add the database and colums and add some data into it, and even run a query on it. However, if I try to run a query using the new table and and existing table (linked) I get the following error:
ODBC--call failed.
[Microsoft][ODBC SQL Server Driver][SQL Server]Cannot resolve collation conflict for equal to operation. (#446)
Any ideas?
my Server and SQL specs: SBS2003 & MSSQL ver 8.0
I have recently moved some native Access tables to SQL Server 7. These tables are updated in code. When the update is done via a SQL statement, I get
"This record is being modified by another user. . . Save, Copy to Clipboard, Drop Changes"
When the record is being updated via DAO code, I get,
"ODBC Call Fail"
Both errors are most irritating and I desperately need to find a way around this. Any suggestions would be greatly appreciated.

Hi
Wrote this snipet of code to use Insert Into. I have an ODBC connection to Oracle with the Tables linked. I can edit, add write querries and do everything I need to do except do an Insert Into. So I am thinking it is my code and seeking guidance.
I select add data from a button on the form. It then calls the code below. I know it is making it up to the db.execute statement and failing at that point. Funny thing is I only get the error "ODBC Call Failed" and no other snippets of information. On top of that I can not relink to the tables as they are now unaccessible and I have to completely close down the program and restart. Any help/assistance will be greatly appreciated.

Hi,
I have a ms access application with a button. Clicking this button runs a sql server 2000 stored procedure. The stored procedure updates product information. When I click the button it updates the products fine. When the users (with lesser permissions than me) click the button, no error message is sent but the transactions are rolled back. Does anyone know why or how this could happen? Please let me know before I pull out the last strands of hair from my head.
Thank you,

Hello, all:
I am connecting to SQL Server 2000 with a trusted connection, and that is working fine. I then am issuing a SQLGetInfo call to find out the SQL_USER_NAME, which is always returning dbo instead of (my) Windows NT login name, which I expect to see. THe authentication is (apparently) confirmed by the SQL Server session monitor where it shows the right Windows NT user name logged in, over ODBC. With a standard SQL Login, untrusted, I definitely get the right user name back, not dbo.
So:
Login Type / user id /returned value from SQLGetInfo
Windows Authentication / Windows login / dbo
SQL Authentication / Windows login (UID) / UID
The problem is that I am trying to confirm that the userid entered in a dialog or passed on the command line to my application matches the actual connected user name inside SQL Server....
My questions:
Is there some pathology in Trusted_Connections that masks the Windows/NT login name and always returns UID 'dbo' from a call to SQLGetInfo? Is there a MSS (public) stored procedure that can robustly give back the logged in user name so I can bypass the SQLGetInfo call?
Hi,
I am producing a php report using SQL queries to show the SLA status of our calls. Each call has response, fix & completion targets. If any of these targets are breached, the whole SLA status is set as 'Breach'.
The results table should look like the one below:

Whereas I can pick the results for the first 6 columns from my Select query, the 'SLA Status' column requires the following calculation:
if (due_date < completed_date)
{ sla_status = 'OK';
}
else sla_status = 'Breach';
The Select statement in my query is looking like this...
Select Distinct CallRef, Description, Severity, ProblemRef, Logdate, Status, Due_date, Completed_date;
The problem is that my query is returning multiple entries for each stage of the call (see below), whereas I just want one entry for each call, with SLA status 'Breach' if any of the stages for the call were out of SLA.

Any help will be much much appreciated, this issue has been bothering me for some time now!!!
I was playing around with the new SQL 2005 CLR functionality andremembered this discussion that I had with Erland Sommarskog concerningperformance of scalar UDFs some time ago (See "Calling sp_oa* infunction" in this newsgroup). In that discussion, Erland made thefollowing comment about UDFs in SQL 2005:[color=blue][color=green]>>The good news is that in SQL 2005, Microsoft has addressed several of[/color][/color]these issues, and the cost of a UDF is not as severe there. In fact fora complex expression, a UDF in written a CLR language may be fasterthanthe corresponding expression using built-in T-SQL functions.<<I thought the I would put this to the test using some of the same SQLas before, but adding a simple scalar CLR UDF into the mix. The testinvolved querying a simple table with about 300,000 rows. Thescenarios are as follows:(A) Use a simple CASE function to calculate a column(B) Use a simple CASE function to calculate a column and as a criterionin the WHERE clause(C) Use a scalar UDF to calculate a column(D) Use a scalar UDF to calculate a column and as a criterion in theWHERE clause(E) Use a scalar CLR UDF to calculate a column(F) Use a scalar CLR UDF to calculate a column and as a criterion inthe WHERE clauseA sample of the results is as follows (time in milliseconds):(295310 row(s) affected)A: 1563(150003 row(s) affected)B: 906(295310 row(s) affected)C: 2703(150003 row(s) affected)D: 2533(295310 row(s) affected)E: 2060(150003 row(s) affected)F: 2190The scalar CLR UDF function was significantly faster than the classicscalar UDF, even for this very simple function. Perhaps a more complexfunction would have shown even a greater difference. Based on this, Imust conclude that Erland was right. Of course, it's still faster tostick with basic built-in functions like CASE.In another test, I decided to run some queries to compare built-inaggregates vs. a couple of simple CLR aggregates as follows:(G) Calculate averages by group using the built-in AVG aggregate(H) Calculate averages by group using a CLR aggregate that similatesthe built-in AVG aggregate(I) Calculate a "trimmed" average by group (average excluding highestand lowest values) using built-in aggregates(J) Calculate a "trimmed" average by group using a CLR aggregatespecially designed for this purposeA sample of the results is as follows (time in milliseconds):(59 row(s) affected)G: 313(59 row(s) affected)H: 890(59 row(s) affected)I: 216(59 row(s) affected)J: 846It seems that the CLR aggregates came with a significant performancepenalty over the built-in aggregates. Perhaps they would pay off if Iwere attempting a very complex type of aggregation. However, at thispoint I'm going to shy away from using these unless I can't find a wayto do the calculation with standard SQL.In a way, I'm happy that basic SQL still seems to be the fastest way toget things done.

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!

Stefan D.
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

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.

Guys I need help with sql server 2005 syntax
My goal is up update a table called UserStats.
I have numerous functions in SQL that return Scalars (one for each statistics I want to use)
How do I then use a stored proceedure to return a table of the values for use on my site?
WIthin SQL Server 2005, there are functions. This feature is new to me and I haven't found anyone that has written their own fucntions? I'm wondering if functions are written the same as stored procedures, and can a function be called from a stored procedure or even from within a query.
hello Im having a difficult time translating this query from Access to SQL because it uses the First/Last functions.
I have a 'Projects' Table and a 'Project_Comments' table, each has a 'Project_ID' field which links the 2 together. What I need to do is retrieve a Project List from the Projects Table and also the first Comment of each project based on the Commend_date field in the Project_Comments table. This is the MS ACCESS query:
SELECT Projects.Project_Number, Projects.Project_Name, First(Project Comments.Comment_Date), First(Project_Comments.Notes)
FROM Projects Left Join Projec_Comments ON
Projects.Project_Number = Project_Comments.Project_Number
GROUP BY Projects.Project_Number, Projects.Project_Name
Now I can use Min() for the Date instead of First, however I dont know what to do with the Notes field. Any help on how to get this over to sql would be greatly appreciated!
Hi,
I have created a function that returns a comma seperated list of product id's from a table. I need to call this function from a stored procedure to help filter my product results, something like the following:
SET @SQL = 'SELECT dbo.Products.ProductID FROM dbo.Products WHERE dbo.Products.ProductID IN (' + dbo.GetModels('dbo.Products.ProductID', '') + '))'
The problem I am having when executing the above is:
"Conversion failed when converting the varchar value 'dbo.Products.ProductID' to data type int."
Can anyone shed some light on how I can call the function, feeding through the product ID from the row of the select statement I am trying to execute (if this makes sense).
Any help would be great.
Matt
Iam trying to convert a date string to date format.....in access I could just use CDate, but SQL apparently does not allow this.
Any help appreciated
Thanks

View 1 Replies View RelatedHi,,I'm having a problem with calling a function from an activex scriptwithin a data transformation. the function takes 6 inputs and returnsa single output. My problem is that after trying all of the stuff onBOL I still can't get it to work. It's on the same database and I'mrunning sql 2000.when I try to call it I get an error message saying "object requiredfunctionname" If I put dbo in front of it I get "object required dbo".Can anyone shed any light on how i call this function and assign theoutput value returned to a variable name.thanks.
View 7 Replies View RelatedHello,
I've created a function that performs modulo. I understand that SQL server 2000 / 2005 uses % for modulo, but we have an application that was written for Oracle. Oracle has a mod(dividend, divisor) function.
As to not rewite the queries, I would like to implement the function below:
the function executes properly but I must prefix it with the dbo schema.
Net: I can execute --- select dbo.mod(9,2) and it returns a 1 just like it should.
but I can not execute --- select mod(9,2) I receive the error "'mod' is not a recognized function name." on SQL 2000 and 2005.
If I can execute select mod(9,2) then I won't need to re-write any queries.
Also, on SQL 2005, I have tried to adjust the default shema, and the execute as clause, but neither helped my cause.
I'm going to try building the function in the CLR, but I think I will be faced with the same problem.
Can someone point me in the right direction?
Thanks
Tom
create function mod
(
@dividend int,
@divisor int
)
RETURNS int
as
begin
declare @mod int
select @mod = @dividend % @divisor
return @mod
end
Hi,
I have to calculate data in function with "EXEC". During runtime I get the Error:
"Only functions and extended stored procedures can be executed from within a function."
I would use a Stored Procedure, but the function is to be called from a view. I don't understand, why that should not be possible. Is there any way to shut that message down or to work around?
btw: Storing all the data in a table, would mean a lot of work, I rather not like to do. ;-)
Thx for any help

I just installed SSRS 2005 and I have experience with SQL.
How come this function does not work?
SELECT SUBSTRING(YEAR_MONTH, 1, 2) AS Expr1
FROM table1
I get a message which states that this command is not supported by the provider?
It works fine with other SQL tools like winsql?
thanks
