This is my first time using Julia and I've written a test script to connect to a database as follows:-
using ODBC
db = ODBC.DSN("DRIVER={SQL Server};SERVER=MyServer;DATABASE=MyDatabase;Trusted_Connection=Yes;");
However, when I execute the code in Jupyter, I get a pop-up each time as shown below. I would like to be able to login automatically using windows authentication and not have to manually enter the login details. Can someone help?
Shoudn't it be True vs Yes:
Trusted_Connection=True;
Also I think you shoud define an ODBC data source in your system and use it's name (e.g. MyDSN) in connection string:
db = ODBC.DSN("DSN=MyDSN;DATABASE=MyDatabase;Trusted_Connection=Yes;");
I found the answer, which is to pass the prompt parameter as follows:
using ODBC
db = ODBC.DSN("DRIVER={SQL Server};SERVER=MyServer;DATABASE=MyDatabase;Trusted_Connection=Yes;";prompt=false);

I have been working on SQL Server 2017 via R (on Rstudio as well as R on SSMS) and i am unable to connect to a specific database. I mention the database name in the connection prompt but, it gets connected only to the master database. Is there something that I am missing while connecting?
The syntax I use for connection is:
conn = "Driver={ODBC Driver 13 for SQL Server};server=;Uid=uid; pwd=pwd;Database = mydb"
I am trying to use both RevoscaleR as well as ODBC() package in Rstudio to connect to a specific database but, it still gets connected to master database. Using RStudio connections pane, if i try to explore the other databases, it shows only dbo schemas and no other schemas even if they exist. Can someone help me in figuring out what might have gone wrong?
Most likely the login you use (the uid) is not authorized for that particular database (it is not created as a user in that database).
Some example code you can run in SSMS as - for example - sa:
--switch over to the database in question
USE mydb
GO
CREATE USER uid FOR LOGIN uid;
The above code creates a user in the database in question with the same name as the login.
Hope this helps!
I am using the NSIS nsODBC plugin to create an systemdsn entry.
When I call the command as shown below it works and creates my system dsn odbc.
nsODBC::AddSysDSN "ODBC Driver 11 for SQL Server" "DSN=test" "server=localhost" "DATABASE=test" "Trusted_Connection=Yes"
Pop $0
Pop $0 Returns "Successful" and in my ODBC Data Source Administrator I see my connection and it works.
But I need to create my system dsn with a username and password, on the forums and site I have seen they say it should look like the following:
nsODBC::AddSysDSN "ODBC Driver 11 for SQL Server" "DSN=test" "server=test" "DATABASE=test" "UID=test" "PWD=test"
Pop $0
When I run this command Pop $0 returns the text "error" and no system dsn is created.
I have checked the SQL server instance it has the test database, a login account called test which is a system admin account, it is in mixed mode authentication.
Any suggestions as to what I am doing wrong as to why it will not create a system dsn with a username and password?
Thanks in advance

That plug-in is badly designed because it uses everything on the stack as its parameters. It is also a very thin wrapper around the database API so as long as your stack is empty before calling then the problem is most likely a missing/wrong parameter and not a bug in the plug-in.
Calling the plugin with parameters like "foo=1" "bar=baz" is "translated" to foo=1\0bar=baz\0\0 which is what you see on MSDN and that is the C/C++ syntax for a double null terminated key-pair string.
Why is Server set to test and not localhost?
The code listed on the MSDN page for ConfigDSN says:
For example, to configure a data source that requires a user ID, password, and database name, a setup application might pass the following keyword-value pairs:
DSN=Personnel Data\0UID=Smith\0PWD=Sesame\0DATABASE=Personnel\0\0
Maybe the pair order matters, I don't know.
I am trying to connect R to Teradata and am not sure what the input items are to the RODBC::odbcDriverConnect(). There is a teradataR package, but it is only used with R versions 3 and under, which I neither have nor want to switch to. Below is a list of the input parameters to get ODBCDriverConnect to work. "Connection" I believe is most important. I need to get an address for a driver that I don't even know if I have. This is what I need most help with. How do I get a driver for Teradata to connect to R? IT at my work is not sure how to do this. Also, if anyone knows of another way to connect Teradata to R (some other package?), please let me know.
connection = ""
case
believeNRows = TRUE
colQuote, tabQuote = colQuote
interpretDot = TRUE
DBMSencoding = "",
rows_at_time = 100
readOnlyOptimize = FALSE
Thank you for your help!
I was able to connect R to Teradata using RODBC package. Here is how to do it if you are working on a pc and have a Teradata driver.
Set up DSN:
Go to: control panel-> administrative tools -> Data Sources (ODBC) -> User DSN tab -> click add-> select Teradata driver (or whatever driver you will be using. ie. could be sql) and press finish.
A box will pop up that needs to be filled in. The following fields need to be filled:
Name: Can be any name you would like. I chose TeraDataRConnection, for example.
Name or IP address (DBC name or address): Mine for example is: Databasename.companyname.com. I looked to see how Microsoft access was connected to the database and in doing that, found the DBC address.
Username: username that you use to connect to database.
Password: password use to connect to databases (if you don't put your password in here, you will have to manually type it into R every time you connect.
In R:
Download RODBC package
library(RODBC)
ch=odbcConnect("TeraDataRConnection", uid="USERNAME HERE",pwd="PASSWORD HERE")
If you want to confim you are connected, you can type in this code to see the tables:
ListOfTables=sqlTables(ch,tableType="TABLE")
That's it!
I am able to connect to Teradata and created a Shiny app which reads data from it.
Firstly we need to install RODBC package in our R. Prerequisite of it is R (≥ 4.0.0) version. No admin access is required to upgrade R even in enterprise laptops.
Follow below steps to successfully setup connection.
Create ODBC Data Sources to connect to Teradata. The connection should be either in 64bit or 32bit, depending on R software.
Use below code snippet to get the data into reactive variable
data <- reactive({
ch <- odbcConnect(dsn = "DSNName", uid = "username", pwd = "password")
sqlQuery(ch,paste('select * from emp ')
})
DSNName - Name of DSN connection created
You can use data() to display and use the value stored in it.
Enjoy!
I am using R 32 bit and am having an issue trying to get the odbcDriverConnect function to work when trying to connect to an Access database. I have successfully connect to the database using odbcConnect, but am also trying to learn how to use the odbcDriverConnect function.
My code is
scallopdata<-odbcDriverConnect("Driver={Microsoft Access Driver (*.mdb, *.accdb)};Dbq=S://adv/Scallop Central/2014 RSARR/2014 RSA Database_9_3_2014.mdb;
Uid=admin;Pwd=")
When I run the code, I get an error message of
ODBC Microsoft Access Driver Login Failed. Could not find file S://adv/Scallop Central/2014 RSARR/2014 RSA Database_9_3_2014.mdb.
I click the OK button which takes me to a Login box. I select the Database... button. This brings me to a Select Database box where I can select the same database that is specified in the Dbq section of code. Once I select the correct database and click OK I am connected to the database.
I am hoping to use the odbcDriverConnect function so that I do not have to set up a new odbc DSN for each database I would like to access. This may just be me not fully understanding the function.
If any one can provide so insight, it would be very helpful.
I am very new to AS400, and I am stuck. I have read documenation but cannot find what I need.
I have an odbc connection to an AS400 server. When I run this command I get an Outfile with everything I need:
CALL QSYS.QCMDEXC('DSPUSRPRF USRPRF(*ALL) OUTPUT(*OUTFILE) OUTFILE(CHHFLE/TEST3)', 0000000061.00000)
Instead of the results going to an outfile I need to receive the results of this command to my script that is connecting through odbc. If I change 'OUTPUT(*OUTFILE)' to 'OUTPUT(*)' I get no results when I try to 'fetchall()'.
Is there any way to get this information through the odbc connection to my script?
EDIT: I am on a linux server, in a python script using pyodbc to connect. I can run sql queries successfully using this connection, but I can't figure out how to get the results of a command to come through as some sort of record set.
I hope I'm interpreting what you're asking correctly. it looks like you're accessing user profile data and dumping it to a file. It looks like you then want to use the contents of that file in a script or something that's running on Windows. If that's the case:
In general, when accessing data in a file from the Windows world, whether through ODBC and VBScript, or .NET, the AS/400 is treated like a database. All files in libraries are exposed via the built-in DB2 database. It's all automatic, and part of the Universal DB2 database.
So, after creating this file, you should have a file named TEST3 in library CHHFLE
You'd create a connection and execute the following SQL statement to read the contents:
Select * From CHHFLE.TEST3
This, of course, assumes that you have proper permissions to access this. You should be able to test this using the iSeries Navigator tool, which includes the ability to run SQL Scripts against the database before doing it in your script.
Added after reading comments above
There's info at this question on connecting to the DB2 from Python. I hope it's helpful.
OUTPUT(*) is not stdout, unfortunately. That means you won't be able to redirect OUTPUT(*) to an ODBC connection. Dumping to a DB2 table via OUTPUT(*OUTFILE) is a good plan. Once that's done, use a standard cursor / fetch loop as though you were working with any other DB2 table.
