I am trying to update my database to a new migration, but it gets stuck on a part where it needs to drop an index. It says: Cannot drop the index 'Player.IX_Player_OrganizationId1', because it does not exist or you do not have permission.
What I am doing is the following:
I open my package manager and run the command: add-migration [name]
Then I run the command: update-database
Then in proceeds to do some tings, altough its gets stuck on the command:
Microsoft.EntityFrameworkCore.Database.Command[20102]
Failed executing DbCommand (2ms) [Parameters=[], CommandType='Text', CommandTimeout='30']
DROP INDEX [IX_Player_OrganizationId1] ON [Player]; Failed executing DbCommand (2ms) [Parameters=[], CommandType='Text',
CommandTimeout='30'] DROP INDEX [IX_Player_OrganizationId1] ON
[Player]; Microsoft.Data.SqlClient.SqlException (0x80131904): Cannot
drop the index 'Player.IX_Player_OrganizationId1', because it does not
exist or you do not have permission.
So what i did was checking if the index is there, i did this with the sp_help player command in an SQL Query. This shows the following:
index_name
PK_Player
Player.IX_Player_OrganizationId1
So it does exist, which means i do not have permission to drop it. So then I runned the SQL query
Drop INDEX "Player.IX_Player_OrganizationId1"
on Player
Which did the job, but my data is not showing correctly in the web application (ASP.NET MVC)
I think this is because i didnt use a migration to update it, but i am not sure. Can anyone help me with either making sure the migration succeeds/giving the PM Console permissions or make sure the data shows correclty in my ASP.NET application.
Thank you in advance!
NOTE: using nuget.org package & Microsoft Visual Studio Offline Packagaes
I have solved this problem; I manually added the index using "indexname", where it should have been [indexname].

What is the right way to backup and restore a MariaDB database that has sequence generation enabled (i.e. NOT autoincrement)? (This includes migrating to a new server.)
Is it possible to instruct the sequence generator to pick up indexing table data at a specific ID value? How?
Steps I take to create my issue
I wish to transfer an application to a new server:
Backup data on source server:
mysqldump --skip-opt --no-create-db --no-create-info --hex-blob [database-name] [...list of tables...] > data-backup.sql
On target server, create new empty database (same name)
Build/run JHipster Spring application on target server: java -jar myapp.jar (Running this application recreates/configures a new instance of the database on the target server.)
Restore data:
mysql [database-name] < data-backup.sql
All the above steps produce no errors (so far).
Problem
When I follow these steps, the database is restored (apparently perfectly). I can log in to the application and access all information. BUT when I attempt to create new entities (i.e. save something to the database), I get an ID 'Duplicate entry' error in the server logs:

Clearly my backup/restore process is not accounting properly for the sequence generator, which generates ID values that conflict with the existing data.
What I am doing wrong? What is the right process of backing up/restoring such a database?
Environment: JHipster 7.7.0 (Angular, monolithic), MariaDB 10.4, OpenJDK 16.0.2_7, OS Windows 10 Pro and openSUSE 15.2, Firefox 98.0.2 and Chrome 99.0.4844.84.
PS: I previously reported this issue here, aimed at the JHipster community, but got limited response. I think I need a MySQL/MariaDB expert opinion on this.
(Apologies in advance: I'm not a database expert. The technique I outline above has served me well for years, but previously I was dealing with AUTO_INCREMENT. This sequence generator has me baffled.)
Ok! I have solutions.
[For the sake if these notes, let's call the database: mydata. Also, in JHipster, the MariaDB sequence generator is called: sequence_generator]
Let's consider two situations:
(1) Simple migration
If you are merely migrating the application to a new server, the process is straight forward:
Step 1: On the original server backup and secure your database: mysqldump -u root -p mydata > mydata.sql
Step 2: Transfer the SQL file to the new server, along with the JHipster JAR file
Step 3: On the new server, create an empty database with the same name, and restore the data: mysql -u root -p mydata < mydata.sql
Step 4: Now launch your JHipster application, and everything should work
(2) Model modification
The assumption is that you have modified your model in some way (e.g. added properties to one or more entities). This solution is fiddly, but it works (for me).
Step 1: Backup your database, and secure it (in case something goes wrong): mysqldump -u root -p mydata > mydata.sql
Step 2: Backup and secure the original JHipster JAR that works with the original database
Step 3: Duplicate your database (schema and data) in a new table: mydata_bk
Step 4: Drop your original database, and create a new empty database
Step 5: Launch your new JHipster JAR, and give it time to create the new database schema, then stop the application
Step 6: Use a tool (DataGrip, sqlYog, etc) to compare the old (mydata_bk) and new schema (mydata), and modify the old schema to match the new schema
Step 7: Restore/copy all data from mydata_bk to mydata, EXCEPT for the tables DATABASECHANGELOG, DATABASECHANGELOGLOCK and the special sequence_generator table
Step 8: Open the mydata.sql SQL file, and at the top, after initial comments, one of the first instructions will read:
--
-- Sequence structure for `sequence_generator`
--
DROP SEQUENCE IF EXISTS `sequence_generator`;
CREATE SEQUENCE `sequence_generator` start with 2000 minvalue 1 maxvalue 9223372036854775806 increment by 50 cache 1000 nocycle ENGINE=InnoDB;
SELECT SETVAL(`sequence_generator`, 201050, 0);
The specific numbers may vary, but the broad details will be similar. In a MariaDB SQL console type/execute each of those SQL statements: DROP SEQUENCE ...;, CREATE SEQUENCE ...;, and SELECT SETVAL(...);
Step 9: Launch your JHipster application.
Hope this helps others that run into similar issues. Let me know if you have a better approach!

Delete all existing migrations and Add-Migration from scratch.
Be sure there's not an existing database (that specified in the connection string) while you add-migrations. If you have an already created database before, migrations cannot be built correctly.

I'm trying to Install SQL Server R Services. I'm using SQL SERVER 2016 RC1. I'm following this step by step tutorial https://msdn.microsoft.com/en-us/library/mt604883.aspx Everything seems to install ok, but I get the following error when testing an R script.
Msg 39021, Level 16, State 1, Line 1
Unable to launch runtime for 'R' script. Please check the configuration of the 'R' runtime.
Msg 39019, Level 16, State 1, Line 1
An external script error occurred:
Unable to launch the runtime. ErrorCode 0x80070490: 1168(Element not found.).
Msg 11536, Level 16, State 1, Line 1
EXECUTE statement failed because its WITH RESULT SETS clause specified 1 result set(s), but the statement only sent 0 result set(s) at run time.
I'm using the following code:
exec sp_execute_external_script #language =N'r',
#script=N'OutputDataSet<-InputDataSet',
#input_data_1 =N'select 1 as hello'
with result sets (([hello] int not null));
go
Any ideas as to what may be going wrong?
Thank You
I had the same issue initially. I had mistakenly skipped the post-installation steps, specifically the step to register the R runtime with SQL Server. See MSDN post: https://msdn.microsoft.com/en-us/library/mt590536.aspx
Try to uninstall using RegisterRext first and then install. Only this worked for me:
"C:\Program Files\Microsoft SQL Server\130\R_SERVER\library\RevoScaleR\rxLibs\x64\RegisterRExt" /uninstall
Then
"C:\Program Files\Microsoft SQL Server\130\R_SERVER\library\RevoScaleR\rxLibs\x64\RegisterRExt" /install
set User Account Control to never notify when apps try to install software or make changes to your computer.
I would like to get HTML content from a certain webpage in my function. I read I can do it with the UTL_HTML package in PLSQL. So I made the following code in the project:
v_webcontent := utl_http.request(v_weblink);
Here the v_webconent and v_weblink are declared earlier. running this in de function gives an PLSQL exception: PLS-00201: identifier 'UTL_HTTP' must be declaredI guess this problem is because the package isn't available (from this link: same error message).
I followed the advice. So I created a new database connection in sql developer as the SYSTEM role (SYS didn't work, it sayd I could only logon using SYSDBA or SYSOPER but both wouldn't take the standard password I created with the database). Then I entered the code in the link above.
GRANT EXECUTE ON SYS.UTL_HTTP TO [database];
The user I created is named 'Database'. It first gave me an error without the [] square brackets. Table or view does not exist so I then put the brackets around it. Now it gives error:
Error starting at line : 1 in command -
GRANT EXECUTE ON SYS.UTL_HTTP TO [database]
Error report -
SQL Error: ORA-00987: missing or invalid username(s)
00987. 00000 - "missing or invalid username(s)"
*Cause:
*Action:
So I have no idea how to fix this. In the link above OP said that he got an other error, so I also checked if I didn't have the same problem. I entered:
SELECT * FROM dba_objects WHERE object_name='UTL_HTTP'
It returned 4 entry's. With owners: SYS, SYS, PUBLIC and APEX_040000.
Can somebody help me? Do I need to logon as SYS and with what passwords?
Since 11g you also have to create an access control list ('ACL') which specifies which users have access to particular domains, it is no longer sufficient to just grant users execute privileges on utl_http!
Something like this should work in 11g(after granting execute privileges on UTL_HTTP to your database user, as specified by the accepted answer) :
SQL> BEGIN
2 DBMS_NETWORK_ACL_ADMIN.CREATE_ACL(acl=>'mikesacl.xml',
3 description=>'access control list example',
4 principal=>'HR',
5 is_grant=>TRUE,
6 privilege=>'connect');
7 commit;
8 end;
9 /
PL/SQL procedure successfully completed.
SQL> begin
2 DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL(
3 acl=>'mikesacl.xml',host=>'*');
4 commit;
5 end;
6 /
PL/SQL procedure successfully completed.
Here is a very helpful link which explains the parameters of the above two functions :
http://www.oracleflash.com/36/Oracle-11g-Access-Control-List-for-External-Network-Services.html
Good luck!
Log on as SYS AS SYSDBA.
Execute grant execute on sys.utl_http to "Database"; Do not use any square brackets!
That should work.
Piece of advice: Do not name your DB user 'Database'.
To reset your SYS password
Run cmd.exe as administrator.
cd to your ${ORACLE_HOME}/database.
Find the PWDsomething.ora file there (where something will be your instance name), copy its name (into clipboard).
Run orapwd file=PWDsomething.ora password=SomePasswordOfMine force=y, where PWDsomething.ora will be replaced with the file name from the step 3 and SomePasswordOfMine must be replaced by whatever password you wish to have.
That might work.
When using korma.db, defdb can take a sqlite3 helper to establish a connexion to a sqlite3 database. However, I've tried placing the database on the root of the project directory, alongside project.clj, and on the resources directory, but when I try to use the db I get:
Failure to execute query with SQL:
SELECT "examples".* FROM "examples" :: []
SQLException:
Message: [SQLITE_ERROR] SQL error or missing database (no such table: examples)
Needless to say my sqlite database contains an examples table. When trying to do this, I get a sqlite.db file of zero bytes placed on the root project dir.
I'm doing this from lein repl within the project, by the way.
Edit: This is what I do when it fails:
(use 'korma.db)
(defdb db (sqlite3 {:db "filename.db"}))
(use 'korma.core)
(defentity examples)
(select examples)
Just in case anybody is wondering or runs into this...
Using version [korma "0.4.2"]
and [org.xerial/sqlite-jdbc "3.7.15-M1"]
in my project.clj:
My project structure looks like:
root/project.clj
root/db/dev.sqlite3
root/src/...
and this is how I use korma to access the db:
(use 'korma.db)
(defdb mydb {:classname "org.sqlite.JDBC"
:subprotocol "sqlite"
:subname "db/dev.sqlite3"})
Basically, using subname, I'm able to search in the root of the lein project. I added db/ in the subname per my dir structure above.
