I am creating web service in zend framework which uses DynamoDB. So I installed DynamoDB in local. But it's not easy to use. Even for inserting data and update any data for testing for purpose I have to write a script.
Is there any DynamoDB client available for MAC ? In which we can insert/update/delete data from UI.
EDIT
Doubts
1) Do I have to run a SQL to see table data? I thought there would be GUI for this.
2) I am not able to use where clause in SQL. What if I want to see one or two records from all? Is there a way to use conditions in this?
3) All fields of a row is not visible and I am not able to scroll it horizontally ?
YES! I've finally found a solution after struggling with this myself:
Run your local dynamodb jar with the following command java -jar DynamoDBLocal.jar -dbPath . [this will create a file in whatever directory the Dynamo jar is located in].
Download SQLite Database Browser and extract/install it.
Start SQLite Database Browser
Navigate to "Open Database" from the file menu
Navigate to the directory from 1. Select the file [in this case, ****_us-east-1]
You should then see the database contents!!
Hope this helps - it's been frustrating me no end!
!! EDIT !! - in response to original question edit.

Yes - you can do a simple "select" statement, for instance in my examples: "SELECT * FROM tweet_item" returns me the following screenshot:
Seemingly inadvertanyl - whilst I couldn't get the direct SELECT * FROM XX WHERE XX to work, the like statement does. For instance SELECT * FROM tweet_item where tweet_item.hashKey like "%425665354447462400%" returns me the tweet with tweet_id [my hashKey] of 425665354447462400:
Strange - I seem to be able to scroll quite happily [although it is Windows not Mac]. It also automatically tries to re-size the outer frame, too.
I ran into this problem and found a relatively new solution : https://github.com/aaronshaf/dynamodb-admin
It has provision for GET/POST/PUT/DELETE.
Although its a paid product, which is a bummer, RazorSQL now supports DynamoDB as well, and does let you change the AWS endpoint to point to a local installation.
The mac version (with a free trial) is available here:
http://razorsql.com/download_mac.html
Here is a very useful ui tool https://github.com/YoyaTeam/dynamodb-manager，It supports almost all data operations。
For Eclipse users:
Amazon provides AWS Toolkit for Eclipse IDE. It can view local and cloud databases. Also if you are using different regions, it has ability to choose from different regions.
You can create attributes, add keys etc..
For installation follow this link: http://docs.aws.amazon.com/toolkit-for-eclipse/v1/user-guide/getting-started.html
Dynobase is new DynamoDB GUI Client which also lets you browse and manipulate local DynamoDB instances: https://dynobase.dev/dynamodb-local-admin-gui/
Unfortunately, it's paid but there's free 7-days trial, works on Mac, Windows and Linux: https://dynobase.dev/

So a friend of mine asked me to help him configure an automatic replication of a table on his MariaDB database to another table that's supposed to be an exact copy of the source/primary table.
The databases are on the same server. MariaDB version 10.2.44. The databases are on a cPanel managed webserver run by a webhost. We are accessing the databases using HeidiSQL, which is what I'm hoping I can use to configure everything.
Upon lots of googling, this is the article I suspect makes the most sense for what we want to do, but it doesn't look like this is automatic to any extent: https://mariadb.com/kb/en/setting-up-replication/
Is this the best way to do what we're trying to do? Is there a better way? Any suggestions?
Thanks!
Like #ysth said, in this case, triggers can be used.
When creating a trigger that "works between different databases", you need to specify the database on the trigger name. So for example:
CREATE TRIGGER database_name.trigger_name
Otherwise you'll get an "Out of schema" error.
The database you need to specify is the one where the "listener" is located. Basically, the place where the condition for the trigger is being checked.
I have a Node-RED flow. It uses a sqlite node. I am using node-red-node-sqlite. My OS is Windows 10.
My sql database is configured just with name "db" :
My question is, where is located the sqlite database file?
I already search in the following places, but didn't found:
C:\Users\user\AppData\Roaming\npm\node_modules\node-red
C:\Users\user\.node-red
Thanks in advance.
Edit
I am also using pm2 with pm2-windows-service to start Node-RED.
If you don't specify a full path to the file in the Database field it will create the file in the current working directory for the process, which will be where you ran either node-red or npm start.
Use full path location with file name.
It should work i guess.
This isn't a valid answer, just a workaround for those who have the same problem.
I could't find my database file. But inside Node-RED everything worked just great. So. this is what I have done as a workaround:
In Node-RED, make some select nodes to get all data from tables
Store the tables values somewhere (in a .txt file or something like that)
Create your database outside Node-RED, somewhere like c:\sqlite\db.db. Check read/write permissions
Create the tables and insert the values stored from old database
In Node-RED, inside "Database", put the complete path of the database. For example, c:\sqlite\db.db
In my case this was easy because I only had two database with less than 10 rows.
Hope this can help others.
Anyway, still waiting for a valid answer :)
I'm looking at switching from MySQL Workbench to Navicat because we're using MariaDB and the incompatibilities are starting to annoy me.
I'm working through the issues of getting Navicat to run on Centos under WINE but assume I will succeed (edit: this failed. The "linux" version requires WINE. Navicat will sort of run with a bit of hacking, but critical features rely on MS-Windows/WINE)
How do I get Navicat to work with git (or any other source code control)? Workbench is sufficiently primitive that file changes either get picked up automatically or completely ignored (almost always a dialog "file on disk has changed, reload?")
Specific problems:
when adding new query files Navicat only seems to rescan the folder when I add a new query. Is there a smart way to do that? (edit: no. You can manually refresh one file at a time by right clicking)
model and query files are buried deep in the WINE tree. Can I relocate them or or symlinks work? I'd rather keep all the DB-related code in one repo, rather than having a special Navicat repo. (edit: yes, but the explanation of how to do so is lengthy)
is there a way to merge a model file if more than one person has changed it? Workbench can't do this but I'd really like the feature. (edit: no, never. Merge the schema SQL files instead)
Also, bonus question: can we make multiple edits using Navicat other than repeated use of the GUI? If I want to change (say) a bunch of columns from VARCHAR(255) to CHAR(20) I'd normally script that in SQL but Navicat models don't do reverse engineering, only "delete the table from the model then re-import it" so there doesn't seem to be a non-tedious way to do that. (edit: no, but they might look at it in the future)
Final edit: I used the Navicat forums and the team were very helpful, but fundamentally Navicat is Windows software and the 64-bit purists behind Centos will never support WINE. For most Linux users this is not a problem, but I work with Centos enthusiasts and have long since lost the argument about which distro to use.
To the 1st question, you can sync it in different ways with a remote database/folder, when you are managing the database with Navicat, just right-click in your current connection and press "refresh", so you will be updated with the server changes. You also can do it with a programmed task.
Another matter is, why would you want to run navicat from wine when it has a native linux version? (I hope that answers the 2nd question)
For the 3rd question note that Navicat has an internal utility to sync data between servers, so you don't need git at all, or at most, you can automate the structure exportation and then sync it with a git repository (in form of a .sql file)
IMHO you need to review your concepts about mariadb and navicat, both are quite flexible and offer several ways to do such things you propose, like sync the data and they also allow to insert git in the workflow, just review your strategy and try to apply some new perspective with the available features.
I'm writing a Ruby program to manage courses run at a university, the modules associated with those courses, and the students registered on the courses and modules. I'm using RubyMine to write the program, and I now want to connect what I've written so far to an SQLite database to check that it works as I expect. But I'm not too sure how to do this in RubyMine.
I've opened the database tool window, and it says "No data sources configured", as well as having two "loading" messages at the top of the window.
If I right click on the window, I get a few options, one of which says "Add data source", from which I can add a "DB data source", or a "DDL data source".
I've only ever written one Ruby program before (about 10 months to a year ago), and I used the command line to write it then, also using the command line to create and edit the SQLite database. How can I set up an SQLite database to run with my program from RubyMine?
Also, is there a huge difference between SQLite and SQLite 3? Are there reasons for using one over the other? Which one would people recommend I use?
EDIT 24/08/2012 at 13:50
I tried selecting the option "Run rake tast" from the 'Tools' menu in RubyMine- it then asked me to enter task name or its part, I tried entering "db:migrate", but it said "no matches found".
Any idea what I should do instead?
Please refer to the documentation, RubyMine connects to the database via the JDBC driver. Most likely you want to use SQLite 3 version, as it's the current version at the moment. Check this video for the overview of the Data Sources features.
To connect your program to the database you don't need JDBC driver, it can be done with the sqlite3-ruby gem.
You can also consider some ORM, like Rails ActiveRecord or DataMapper, or Sequel.
With unixODBC you can use a simple command line utility called "isql" to test your connection and permissions of some queries. Without having to write extra code or install libs or bloated programs, is there a simple way to open up X data source send some sql commands and be done with it?
Doing this on the command line would be preferable.
One way to create a quick test query in Windows via an ODBC connection is using the DQY format.
To achieve this, create a DQY file (e.g. test.dqy) containing the magic first two lines (XLODBC and 1) as below, followed by your ODBC connection string on the third line and your query on the fourth line (all on one line), e.g.:
XLODBC
1
Driver={Microsoft ODBC for Oracle};server=DB;uid=scott;pwd=tiger;
SELECT COUNT(1) n FROM emp
Then, if you open the file by double-clicking it, it will open in Excel and populate the worksheet with the results of the query.
Make a file SOMEFILENAME.udl then double click on it and set it up as an ODBC connection object, username, pwd, target server
You can use the "Test Connection" feature after creating the ODBC connection through Control Panel > Administrative Tools > Data Sources.
To test a SQL command itself you could try:
http://www.sqledit.com/odbc/runner.html
http://www.sqledit.com/sqlrun.zip
Or (perhaps easier and more useful in the long run) you can make a test ASP.NET or PHP page in a couple minutes to run SQL statement yourself through IIS.
For ad hoc queries, the ODBC Test utility is pretty handy. Its design and interface is more oriented toward testing various parts of the ODBC API. But it works quite nicely for running queries and showing the output. It is part of the Microsoft Data Access Components.
To run a query, you can click the connect button (or use ctrl-F), choose a data source, type a query, then ctrl-E to execute it and ctrl-R to display the results (e.g., if it is a SELECT or something that returns a cursor).
a simple way is:
create a fake "*.UDL" file on desktop
(UDL files are described here:
https://msdn.microsoft.com/en-us/library/e38h511e(v=vs.71).aspx.
in case you can also customized it as explained there. )
It's been a while but since I precisely have the answer to the question, I'll share it and maybe someone will benefit from it.
Jaime de Los Hoyos wrote a very nice program to precisely do that: ODBC Query Tool.
Unfortunately, Jaime's website is defunct but you can still find the program and its source code at this location:
https://sourceforge.net/projects/odbc-query-tool/files/latest_release/
The program is GUI based and consists of a single executable file, no need to install anything on the machine.
