SEVERE:NULL Preferences during startup Oracle SQL Developer - oracle-sqldeveloper

While I compile and debug every procedure I'm getting error SEVERE: NULL Preferences during startup And oracle SQL developer getting hung.

I faced this issue yesterday. As I was looking for an answer, I came across this unanswered question of yours - !
However by going through how some queries of the stored procedure were written, I realized that:
There was another way of writing it with the same result set.
I was missing single quotation for a query assigned to a variable.
Thus, making those corrections, I found the problem gone - !

keep the backup by renaming the system_cache folder at below path:
C:\Users\{username}\AppData\Roaming\SQL Developer\system17.4.0.355.2349
The error will be gone.

How to remove Routine Group error from workbench?

I'm using MySQL Workbench and I am trying to create a routine. However, At the time of creating routine some error comes,then i deleted that routine. Now I synchronize the model with the existing database, the Routine group error is coming, though i remove that routine group. Can anyone help me how to remove this error from Model?
The _SYNTAX_ERROR suffix is added by MySQL Workbench to indicate that it found a syntax error in your routine code. Once you fixed that the name will change back to what you gave it. And then you can also synchronize your model.
I faced the same issue, cause i copy&pasted some c# code into a routine group, and it immediately became invisible by workbench. Synchronization now always reporte errors, even after deleting the whole routine group. The faulty code was stuck somewhere, inaccessible through the Workbench UI.
Just found a solution atm:
Do a regular synchronization and tell Workbench to change the sync-direction on the error entries. This will remove the faulty lines of code, even if they are not accessible through the Workbench UI.

ODBC: Export from Microsoft Access to Postgres fails

I have a large database that I am currently exporting from Microsoft Access (Version 2006 Build 13001.20384) to PostgreSQL 10.12 (Ubuntu 10.12-0ubuntu0.18.04.1). So far this worked very well, but I have problems with one particular table. When I start the export, I get the following error message:
ERROR: syntax error at or near '/';
Error while executing the query (#1)
Unfortunately I do not know how to deal with this error message and I have not found any information about this message on the Internet. Maybe someone here can help me.
[I copy my previous comment, since it contains useful content for the solution, so this question can appear as solved... and it contains also suggestions for someone in the future with the same problem.]
You say "with one particular table"... maybe the name of that table or a column name of that table is a keyword for postgresql and not for access (it seems the name contain a '/').
Try to split the import if you don't know the table to isolate the problem. E.g. divide the query in 2 halves, then do the same for the half that give the syntax error. If you update your question with the table definition that gives error we can help you find the exact problem if you can't figure it out.

The method .map in the type AbstractJavaRDDLike<<>> is not applicable for the arguments

I am getting an error in talend. PFA.
Please find more details of the mapping.
Can you please help me here?.
Thank You
Tom
This was an issue with code generation of Talend Bigdata version.
There were 5 subjobs in my job.
I was testing the functionality of last three subjobs.(Off late i have added 3 extra tSql components into my 4th subjob , which you can see in the screenshot).
For that i have de-activated the first two subjobs.(I have de-activated the first two subjobs earlier as well and unit tested which was fine)
I assumed this was the issue with code generation of talend.
(Earlier also I faced similar issue with .map() function of tSql component. That time i deleted tSql component and created it again and issue went away.)
I proceeded with the following trial and error method.
I closed the job and reopened again ( issue exists)
I restarted Talend tool and reopened again (issue exists)
I deleted the tSql components and created them again (issue exists)
I activated the de-activated subjobs and then checked again(ISSUE DISAPPEARED)

Strange ORA-06508 error

While working on one of the production issue I came across one error in oracle.
ORA-06508: PL/SQL: could not find program unit being called
When i checked in the database i can't found any invalid objects using below query.
select * from user_objects where status <> 'VALID';
Once all the packages are recompiled by me and then tried there was no error. This is occurring in Database from sometime. Did anyone faced any such issues in past.
Can you please help me finding the RCA for this issue.

Crystal Reports - Failed to open a rowset

What can be done to resolve the exception:
CrystalDecisions.CrystalReports.Engine.InternalException: Failed to open a rowset.
This is a generic error in Crystal Reports whenever the report query fails. There can be a number of causes. If your report was targeted to a specific database and then the database was changed without updated the report, this can cause it. It can also be caused by something in the query itself failing, such as if the report is based on a stored procedure that doesn't exist on the database against which the report is running. Try verifying the database for the report.
As said this is a generic error, and like all such errors it's a very frustrating one. The problem is that VS 2003 has no preview option for crystal reports so it's hard to track down the source of the problem. So best way to solve this is to create a blank project in vs 2005 or later, import the crystal report, and run preview. You will get a more specific error then.
I had the same issue, and received this error message:
One ore more fields could not be found in the result set. Use Verify Database to update the report.
Error in File filename {9FEE6406-1613-409A-B9BD-C5FDA24E3DEE}.rpt:
The rowset column could not be found.
I was using a stored procedure to collect data for the report, and sure enough I was passing an invalid parameter for the SP. Double check the type and value of the parameters if you are using a SP to populate the report data.
Good luck!
I have also gone through same error with report having sub reports. Issue resolved as i switch to each sub report and make it verify again with database/tables/views.
This is caused by some discrepancy in your relations, like opposite left joins or something similar. CR has also the bad habit to create 'default' links each time you modify the list of tables and views needed for the report. It can even sometimes automatically create recursive links that might not be viewable 'at once' in the relations screen.
If you cannot find which relation(s) is causing the trouble (sometimes it is not so obvious), you'll have to make some trial & errors test by adding/removing tables from your report.
Every time you add a new table in crystal it adds its own links on already linked tables, some times it even links the 2 fields from the same table.
Make sure you know your links in order to go through after you add a table and scroll all tables to see for any links create from to the same table
I received :
CrystalDecisions.CrystalReports.Engine.InternalException was unhandled
Message=The Report Application Server failed
Google brought me here. For those that have similar problems.
For the record: I had a byte[] array with an image and removed the log from the report and the error stopped. I now have to figure out what I have done wrong with the logo.
I had this problem - we use SQL logins for our security (not integrated / DSN connections)
By granting execute permissions to the user for my stored procedure I fixed the problem.
Really, really couldn't hate Crystal more for their exception masking - let this be a lesson to all programmers;
Try
'your code here
Catch
Throw new exception("Hey, here's a really friendly but completely useless error message")
End Try
will result in pain for future developers - DON'T DO IT!
When you verify your database it might tell you that it is up to date, in that case you have two more options to check for:
a) Refreshing the report (a lightning-shaped icon), if you have a problem with a field, such as a SQL Field, it will give you the error and then show you the edit window for the field.
b) Running the query directly on SQL, if there is a problem with the query itself you will also get this message in Crystal but SQL will tell you exactly what went wrong.
Check Changing Crystal Report Database logon information at runtime in VS2005 for help.
Important line in it is:
table.Location = Database & ".dbo." & table.Name
For me, the problem was fixed when I logged of and logged back to the SQL server that the report was connecting to
In your store procedure If you are using
SET NOCOUNT ON;
Then just remove this
--SET NOCOUNT ON;
Now verify your report database, build & run your solution.
