I added new rows to my database through SQLiteManager but I cannot see those values in my tableview. My old values are seen. More interestingly, I deleted my database file but I can see my old values again in my tableview. When I created new database with new name, it sees that. How can I make it perceive new values?
Not directly an answer as there are at least two SQLite Managers.
SQLiteManager (standalone) and SQLite Manager the Firefox Plugin.
If you haven't tried the Firefox Plugin yet I'd strongly recommend doing so. I'm very happy with it and have never touched another SQLite Browser since.

I am really sorry to ask a simple question like this, but it is getting frustrating. I installed neo4j 4.0.4 on my Windows machine, created a new project as shown in the official tutorial video and set a password for my local graph. Funnily, the tutorial video ends after setting the password and opening the browser not showing how to perform Cypher queries on this newly created database. In neo4j Desktop my database is shown correctly and it seems to be up and running.
However, when I try to connect to this database via the browser, I do not see the database at all. It is so confusing when connecting to the server to specify a username and password, if you only need to set a password for your database?! The default neo4j user can see the system and default database but not my project database. In addition, I cannot link files from the project directory in Cypher queries. I tried to disable authentication, but it did not help at all.
When I issue SHOW DATABASES command, it does not list my database as well.
Update / Edit:
Seems I misunderstood the concept of projects. Every database is named neo4j - default, regardless of the name specified in the project ?!. However, I still cannot access project files. So far, I copied the files manually in the database directory under "imports". But I guess that is not the intended way.
After importing data to this default database, it still shows no data in the project itself.
Data files in the imports directory are not automatically imported into the DB. That is because neo4j has no idea how you want to store that data as nodes and relationships.
So, it is up to you to determine your desired data model, and then write the appropriate code to enforce that data model.
You can take a look at this page to learn about how to import CSV data (probably the most commonly used import data format).
I am working on a iOS mobile application using Xcode as the IDE and Swift as the language of choice. I added a column to the SQLite database that interacts with my application but unfortunately when I attempt to perform any database operations through the application the column is not recognized.
The following error is sent:
DB Error: 1 "table xyz has no column named column_name"
When I added the column I also increased the database version or user_version in SQLiteStudio.
Is there something else I should be doing to cause the application to recognize the changes? I know uninstalling and reinstalling would work but that is not an option of course as I cannot lose the data currently housed in the database. My other idea was to put all the data in temporary variables or something like that, drop and recreate the tables and reinsert the data. I wasn't sure if this was a good course of action though. Any help with this is appreciated.
I'm trying to overcome the following issue...
I have a MariaDB database that is used for an IOS application.
I'm about to release a new version to the apple store that uses a different version of the schema of the database. means all achievement related tables are modified.
can liquibase be used to configure the changes and allow selected users to connect and work with the schema as if the old schema version is configured, and to actually make the actual changes to the new schema?
before I release the application I need to provide apple with a test version so they will confirm it. so I want users that are connected from apple to see the new achievements features and to work with the new schema while regular users to still be able to user to previous version of the application and to work with the old schema that behind the scenes will actually update the database according to the new schema.
I hope I explained myself properly.
can Liquibase do that ? or it's just like a git for db changes ?
thank you! :)
I've deleted all my nodes and relationships (Delete all nodes and relationships in neo4j 1.8), but I see that in Neo4j Browser the "property keys" that existed before the deletion remain.
See the picture below:
How can I make all the "Property Keys" go away too, so I can end up with a fresh new database? I understand this orphan property keys do not pose a problem themselves, but they clutter the browser experience and will start confusing with newer properties.
Thanks!
You should be able to clear everything out by:
stopping your Neo4j database
deleting everything matching data/graph.db/* (look inside the graph.db folder)
starting up again.
What version of Neo4j are you using? Prior to to version 2.3 there is a file named keystore in the data/ directory that was used to populate this in the browser. Deleting this file will clear out the Labels, Relationship Types, and Property Keys listed in the browser.
Looks like this has changed now with Neo4j 2.3 so if you are using the latest version I don't think you'll have this file.
In the manual you can see that there is currently no way to disentangle which property keys are currently used without traversing the graph.
http://neo4j.com/docs/stable/rest-api-property-values.html#_property_keys
Which is a bummer because I'd like to do the same thing. TBC.
I have Neo4j Community Edition 3.2. To get rid of the property keys (and get rid of the entire DB), I completely uninstalled Neo4j, deleted the Neo4j folder in C:\Program Files and then reinstalled the package again so that I had a fresh DB to work with. Not ideal to delete everything but it worked for me.
I got rid of the properties by open a new DB.|(I didn't want to delete my old folder )
Create a new folder beside the default folder
stop the server
choose the new folder and start again a new DB with new PW
Actually, there is not a way to just delete the unused properties. You need to recreate the graph or use a tool to copy neo4j stores called "store-utils".
Webmatrix is hanged while I query cmsDocument table in SQL CE database, I can query other tables but this gives me error, and it says that "Unable to cast object of type 'System.DBNull' to type 'System.String'.". I also found out that cmsDocumentType table query is also a problem. How will I fix this?
And another issue is the content, document type and template I created previously are gone and just the old content is available. I renamed the main node in umbraco 6.16 site and added new nodes , saved and published. Now all new contents are lost.
I think these two issues are linked. I appreciate any suggestion.
I just found out that after there is any change in the content, the whole website should be refreshed in the WebMatrix. Otherwise, all the changes will be disappeared when the project is closed.
