I have look everywhere for this issue. And after six hours yesterday and an hour today I decided to break down and ask the good fellows of stack overflow.
I set up Oracle 10.2.0 (which was an uphill battle) and finally got sql loader working, which I need because TOAD takes 15+hours to load 400k records. So my question is not how to resolve this error, I know the error. I have read nearly 4 tutorials on fixing the error. I want to know, since my TOAD is connected to the database just fine, is there a way I can get all the info from TOAD to populate/verify that my TNSNAMES.ora and sqlnet.ora files are correctly configured? I copy and pasted the information but it won't work anyway.
Also, aside from those two files, are there any other issues that could be preventing this, as a bit of background, I had to reinstall oracle 10g because the admin tools were not in place for the sql loader. Since the sql loader runs, I figured the install is just fine. If you need more info from me comment and I will edit.
Thanks guys,
Instead of using a tns name you can try connecting using ezconnect:
sqlldr username/password#//localhost:1521/orcl
If this solves the issue the tns name used could not be resolved properly. As you say you had to reinstall oracle to get the admin tools I suspect you might be looking at the tnsnames.ora file from the wrong oracle home.

I am completely baffled by SQL Server and OPENROWSET permissions.
Our team has an AD Group. This group is included in the DEV server's Windows Administrators local group. This same AD group has SysAdmin privilege on the local installation of SQL Server 2017.
Attempting to run the command:
SELECT *
FROM OPENROWSET('Microsoft.ACE.OLEDB.12.0','Excel 12.0;Database=C:\Work\test.xls;HDR=YES',['sheet1$'])
works for me, but for none of my teammates.
If there is a definitive document on the security requirements for using the OPENROWSET command - I have not found it (and please - don't refer me to learn.microsoft.com - that documentation is not written in any way that I understand).
There are other issues I have found including if I change the name of the sheet in the Excel workbook - the command fails (and yes - I closed the book after making the change).
Finally - some feedback on the use of OPENROWSET - is it generally a good idea? a bad idea? pretty much neutral but be prepared for these kinds of problems?
I hope this question is specific enough to be answered - I have probably spent 20+ hours trying to figure out how to understand how this works so I can make it work and use it consistently.
Thanks!
So honestly troubleshooting security/permissions and errors with SQL Server is probably the most frustrating aspects of my job.
First few questions and thoughts about your dilemma.
Do you really want to be granting your team connected to your db
sysadmin rights? I wouldn't do that period, full-stop.
Will the data be refreshed? If yes, I suggest you ingest this data
into a sql table with a process, perhaps python, ssis, dts package,
powershell, whatever you fancy.
If the data will always be static in that one excel file, I'd suggest perhaps making it act like a linked server for (hopefully) fewer permission issues? Also, it's easier to query that way, from my memory.
In any event, this article (non msdn link) may help? I've done it this way once before and had slightly less of a difficult time, but then again it involves adding a driver (usually) to the sql server. BUT, then I did not have to allow multiple users sysadmin - and I think ANYTHING is better than that.
https://www.sqlshack.com/query-excel-data-using-sql-server-linked-servers/
Sometimes the issue is not with the user running the query, but SQL Server using the account it runs as - to get permissions on the file. This article goes over that aspect as well. I'm not sure that is your issue as you say it works for me but not for thee, but maybe read that portion of the article at least?
While trying to generate the diagram for a database (in SQL Server 2017), I am getting an error
Array out of Index
When I restart the application, it works fine for some time, and after few minutes, when I try to add a new table to the Diagram, it shows that same error again.
Is there any solution to avoid this problem?
This sounds like it's a bug with SSMS (v17.4 in my case).
Others have reported similar issues here: https://stackoverflow.com/a/44914581/4768230.
Alternatively, others have suggested making sure you have schema declared for all your tables can possibly help - https://stackoverflow.com/a/44660066/4768230 (I haven't tried this though).
Below is an alternative answer that applies to a very specific situation.
The above answer will most likely solve your problem. However if you run SSMS as a different user than you are logged into Windows as you may get this error.
The workarounds are to either
Use your normal Windows to connect to the SQL Server (which may not be allowed depending on your situation)
User Remote Desktop to connect to a machine with your SQL Account.
Tested with:
Windows 7 64bit
SSMS 17.7
This situation might be related to the computer not being enabled to use Kerberos Double-Hop active directory but this statement is complete conjecture.
I am getting an error frequently while converting access database to sql which is given below as
Conversion Error , There is nothing to process in ssma while converting from access to sql
If anyone has faced same problem
please share the answer
Thanks in advance.
i got the answer here it is..
According to the log, in your start menu you should have two shortcuts, one to 32-bit version, another to 64-bit. Or you can go to the folder where ssma is installed (again by looking at the shortcut), and see if there are two similar executables. Try both.

After hours, I realized that the access file corrupts after a few tries. When i could, I took the original access file and made the complete convertion.

I initially thought my database password was compromised. So I changed my password to a more difficult one, but after a couple of days, it appeared again. Anyone knows how it got into the database like that and how to prevent it?
UPDATE:
After some investigation, I suspect this might be caused by a software which I downloaded to schedule backup SQL databases. I've reformatted my local machine and start all over again, it did not happened anymore.

I'm in a database class and the teacher wants us to connect through ssh to an oracle database setup on a school server and it's been extremely frustrating. She wants us to turn in an sql file that will create all the necessary table, insert tuples, run certain select commands which I've found to be very hard to get an sql file with everything after i get everything right and I haven't found a way to test the sql file against the server and I don't think I have permission to drop tables anyway. Anyway my question is there a way I can take an sql file with create table and insert commands to convert it to something like an access .mba database or something local i can mess around with? and help would be greatly appreciated didn't find much help on google.
You seem to be confusing terminology a bit; SQL*Plus is a client application, and the database is a shared server resource. You want to create schema objects from an SQL file, I think. But anyway...
There's a very useful online resource for experimenting with bits of SQL in various flavours, SQL Fiddle. Technically not 'offline' of course, but I'm taking that to mean off your school's network, not necessarily completely isolated. You can create tables and run your inserts in the schema panel, and then run queries against that. Make sure you pick the right database product from the drop-down menu so you're using syntax that is valid for your class. You'll see a lot of answers here with links to demonstration fiddles.
That's great for a lot of things but if you want something a bit more robust and scalable, and entirely offline, you can install VirtualBox and get a pre-built developer VM image which gives you a ready-to-go Linux environment with a database installed and running. You can run whatever you want against that, you have SQL*Plus and SQL Developer available, and you can connect to the DB from your host machine if you want to. You can create and test your scripts against that, and in a format that will be closer to what you have to hand in than you'd use with SQL Fiddle.
This is much less work than installing the Oracle software yourself and learning how to create and manage the database, which I'm guessing is a bit more advanced than you need at the moment, based purely on the kinds of thing your question suggests you're dong at the moment. I think you'd learn a lot from the installation and build process, but I'd get comfortable with Oracle first, and maybe practice in a VM first as it's so much easier to trash it and start again when you mess something up.
If I wanted 'something local I can mess around with', I would go for a VM image. Mo posted a walkthrough of the VM setup as a comment to a previous similar answer, which you might find helpful.
"Something local I can mess around with" in terms of Oracle Database is Oracle Database 11g Express Edition. It's free and can be downloaded from oracle.com. You certainly can test sql-files run through sqlplus on Oracle Database XE.
To get the MS Access (GUI) feeling, download SQL Developer. It's free.
Best of luck!
