Previously i was using godror package to connect to oracle database client. And now i want to implement ORM in my system and want to connect to oracle using GORM package but it seems i am unable to do it though.
I did found out a package https://github.com/CengSin/oracle but the package installation seem to fail. Trying:
go get github.com/cengsin/oracle
I seem to be stuck on this.
So, it seems that while installing package go get github.com/cengsin/oracle , gorm package needed to be of version less than or equal to v1.20.1. I downgraded my gorm package to version 1.20.1 and it solved my issue.

Old Question, but this might help others:
Seems like the friendly URL feature introduced in APEX 20.1 is causing this issue. A workaround for me is just disabling that in the Application Definition Atrributes.
I had the same problem after upgrading from Oracle Apex 19.2 to Oracle Apex 20.2. I tried everything and nothing happened. I found this:
https://docs.oracle.com/en/database/oracle/application-express/20.1/htmrn/index.html#HTMRN-GUID-175AC460-3BCB-4871-A14C-5A232EDF8CAD
I'm not sure if this is the case, but I can't find any other explanation - in section 2.1.1 Oracle Database Requirement it is said that version 20.2 is compatible with database version 11.2.0.4 and above. Mine is 11.2.0.3. Probably doesn't work for that. Check your version of the database and share if you are below the required one to know if I guess correctly. If so, and you want APEX 20.2, you may need to update your database version first, if a possible.
I hope I helped.
I have installed Neo4J 4.1.0 on Windows 10. When I run the following command I get the error.
CALL algo.list()
ERROR
Neo.ClientError.Procedure.ProcedureNotFound
There is no procedure with the name algo.list registered for this database instance. Please ensure you've spelled the procedure name correctly and that the procedure is properly deployed.
Neo4j 4.x does not support the Graph Algorithms library.
Instead, you should be using the new Graph Data Science library. In that library, the equivalent query would be gds.list(), as in:
CALL gds.list
I am trying to install ODT with ODAC in order to use Oracle with Entity Framework
it gives me the error
[INS-50016] Please install in a Regular Client Home, a new Oracle Home or an existing ODAC Home.
The error message is quite clear. You have to install also an Oracle Client (e.g. the Instant Client) - unless you use the Oracle Data Provider for .NET Managed Driver.
In case you have an Oracle Client already installed it might be the wrong version. Version of Oracle Client and Oracle Data Provider have to match exactly!
Instead of using ODAC, try the NuGet package. Oracle.ManagedDataAccess.EntityFramework
I am using Oracle SQL Developer version 4.1.0.19.
So this can be a very simple issue but I cannot seem to find the solution anywhere as I have just started using SQL Developer.
I type in this query
create table Student(Stu_id INTEGER,Stu_name VARCHAR(60),Stu_email VARCHAR(60))
select * from Student
And when I Run the SELECT query, I get an error something like this:
Method oracle/jdbc/driver/T4CCallableStatement.isClosed()Z is abstract
I have no idea as to why this is happening , this may be very stupid but I cannot seem to find a solution.
BTW I am using Oracle 11g version.
How did you install SQL Developer? Can you download the zip off of OTN and extract it to a fresh directory and try running it from there?
Your error message indicates something VERY bad is wrong with one of the drivers. Which makes me wonder if you messed with one of the JARs or are attempting to use an old Oracle Client with a THICK connection.
I am new to R and trying to connect to Oracle using the way told here.
I downloaded instant client but could not find anything apart from some .dll files there.
Request all to please guide me step by step as to how to connect to Oracle from R. I have had a look at some of the solutions but they couldnt work out.
Please tell me if at all there, the prerequisites to connecting to oracle from R.
BTW, I am using oracle sql developer.
If the client that you already use on your desktop uses JDBC, then it's probably simplest to use RJDBC package and use the same URLs that your desktop package used!
library(RJDBC)
drv <- JDBC("oracle.jdbc.OracleDriver",
"/home/sean/local/DbVisualizer/jdbc/oracle/ojdbc6.jar", "`")
conn <- dbConnect(drv, "jdbc:oracle:thin://localhost/test")
dbListTables(conn)
data(iris)
dbWriteTable(conn, "iris", iris)
dbGetQuery(conn, "select count(*) from iris")
d <- dbReadTable(conn, "iris")
You'll obviously have to change the path to the driver jar file and the connection string.
It might not be quite as fast as a native driver, but I found it easier to get working!
I advice best way is to install oracle R enterprise edition packages.
This will help to connect to oracle as well as it includes many other features.
You can download these packages for free from the below link.
http://www.oracle.com/technetwork/database/options/advanced-analytics/r-enterprise/ore-downloads-1502823.html
Download Client as well as Client Supporting packages and install these packages through either R console or R Studio.
Once installed use library(ore) to load the library.
you can use ore.connect() function to connect to oracle and ore.sync() function to sync the tables and views into r so that u can use that as r objects.
You can refer this document for the syntax for ore.connect() and also for other available functions.
http://www.oracle.com/technetwork/database/options/advanced-analytics/r-enterprise/ore-reference-manual-1882822.pdf
ore.ls() will help you to list the available ore objects.
to use it as an r data frame use the function:
data=ore.pull(table_name)
