I already assign data source and get these table, but I still can not Mapping my Column name (like the picture)
How should I do it?
I'm using H2 DB.
I think you have only selected the "current schema" - which is the one you used to create your datasource/connection. You need to add/select the owning schema for the objects you wish to map.
OPTION 1 -
During Datasource Setup:
Data Sources and Drivers Window
Select the "Schemas" tab (the tool opens on the "General" tab) and choose the schema under which the object you are looking to map exists.
OPTION 2 -
After Datasource Setup
You can follow the instructions for new datasource setup if you can get back to the window where you initially set up the datasource, however, there is a shortcut. If you were able to successfully create a datasource, you should see that data source in the IntelliJ "Database Tool Window" (View > Tool Windows > Database). There is a small pill icon that you can interact with. Mine says "3 of 2195" - this is telling you that you have visibility of 3 schemas of a total 2195 available. Click the pill icon. Find the schema that owns the table you need to map and select it.
After Option 1 OR 2
You should then be able to navigate to the persistence tool, right click your project, and select "Generate Persistence Mapping", then click "By Database Schema". Once you select a datasource in the "Import Database Schema Window" you should see all the objects(tables) available for mapping.
NOTE:
I am running IntelliJ Ultimate Edition v2020.1. I am connecting and mapping objects from an enterprise Oracle 12c database (can't really share screenshots so I will try to be descriptive)
I know I was pulling my hair out so I hope someone finds this helpful!

I recently installed Datagrip to view my Company's Postgres database, however I am currently unable to view the tables in the different schemas by clicking on the schema name:
In the image, I've clicked to open and show the ab-testing schema, however nothing appears below it. This behavior is consistent across all of the schemas in the database. I am able to use the query editor to query tables in the schemas (assuming i know the table names), yet I cannot see the names in the left-side panel. I am using datagrip 2020.2
Thanks!
I had the same problem with a MySQL database. As a test, I used the MariaDB driver instead of the MySQL driver as usual. This was intentional and not an oversight, but it was not a good idea!
The tables, views and server objects were not displayed. Although I was able to display the tables and views after activating Schema Properties -> Advanced -> "Introspect using JDBC metadata", the server objects were not displayed. Working with the displayed tables and views was not possible in the usual way.
Only when I used the MySQL driver again, everything worked correctly again. The tables, views and server objects were displayed correctly and the work with it was possible in the usual way.
As a small quintessence I would like to recommend to all who "struggle" with similar problems to check your chosen drivers. Maybe the problem is caused by choosing the wrong driver, as it was in my case.
Whick kind of message do you get when instrospecting the schema?
I had a java.io.CharConversionException caused by a not valid UTF-8 string.
If this is the case, you can add the following VM option -Ddb2.jcc.charsetDecoderEncoder=3.
I am connected to an Autonomous DB in Oracle Cloud. I created a TYPE database object in my schema. When I try to view the details of the TYPE, the metadata browser does not even list "Types" as a node in the tree structure.
The owner of the type is the schema that I am logged into. I accessed the Object Browser via SQL Workshop in Oracle APEX and I can see that the type that I have created is displayed there.
Is there any setting that I can modify within SQLDeveloper so that it will show me the Types node in the navigator?
sqldeveloper version: Version 19.2.1.247
Build: 247.2212
I am using this on MacOS
The Autonomous team asked us (SQLDev) to hide a bunch of stuff...like indexes, materialized views, etc.
They weren't supported in the first iteration of the service...but now they are.
In a future release (20.2, maybe) these objects will all be displayed again, whether you can create them or not.
Our Oracle database has 500+ database users ( one for each 'human' user ). We are using TOAD Version 11.5
After every logon, I have to switch to the application schema, which means choosing the schema from a very long "users" dropdown list.
Is there a way to set a default schema upon logon ?
If you just want to pre-select the schema in the Schema Browser, for example, then right-click the Schema Dropdown and choose the "Set XYZ as Default Schema" menu item. If you are referring to some other place in Toad then please be specific.
You can set an Auto Connect connection too. From the session/new connection window, scroll right and check the box for "Auto Connect" on the connection you want. When you start Toad, it will auto-connect to the entry you selected.
I'm trying to define a Redshift connection in DataGrip but couldn't find any Redshift driver in the UI. I tried using both Postgres and generic Database Driver with no luck.
Has someone been able to configure this?
If you want to connect DataGrip to Redshift I suggest you use the jdbc drivers from AWS. Just download them to a directory where you can keep them.
Then you open DataGrip and go to the data sources menu (⌘;).
Right-Click on one of the pre-installed drivers or somewhere in the driver section. And select 'Add → Driver'
Give it a good name like 'Redshift' and in the bottom part, click on the + Symbol under Driver files, select the driver you just downloaded and click OK.
Under class, select com.amazon.redshift.jdbc41.Driver, under Dialect, select PostgreSQL.
Now you can go to the data sources menu (⌘;) and click on the "+" symbol in the top left corner and select the Driver you just created (in my case it's called "Redshift") as the data source type.
Now copy your redshift jdbc url (you can find it in your cluster configuration under "Cluster Database Properties") into the URL field and fill the user and password fields with your credentials.
Now can you click on "Test Connection" and it should work.
I hope this helps. If you have further questions or problems to follow the instructions, feel free to comment.
DataGrip added the native support for Amazon Redshift. So now it became a lot easier.
I succeed after all with Postgres driver (I had to add SSH tunnel - not relevant for this problem
I am trying to reflect new changes or add a new table to my model in EDMX file using 'Update Model From Database.' Then i get this error message in Update Wizard saying "Error retrieving Database information. An Item with the same key has already been added."
I am using DB2 database and VS 2010.
Please let me know how i can add a new table or reflect the changes to my model with the changes made to the database. Right now i am deleting the entire model and recreating the new one.
Any help is appreciated.
I was getting this same error. In my case with DB2 9.5 LUW the solution was to remove duplicate named stored procedures on the server. DB2 lets you have multiple stored procs with the same name but different definitions (ie different parameters). But apparently this isn't compatible with Entity Framework. Fortunately for me the duplicates were actually unused old versions.
An alternative is to edit your EDM file in XML editor mode.
I have followed the solution provided by vikrantislav. And in addition to that, I made one more change. By default EF tool brings objects from all the exiting schemas. So make sure you don't have duplicate store procedures in any of those schemas or change the connection properties to filter out by a specific schema. In my case I have filtered out by specific schema as I don't want to mess up with someone else's store procedures in other schemas. And now "update model from database" wizard started working. what a relief.
