Before you can add a table, you first have to select a database. you can create a new database with: CREATE DATABASE database_name you can connect to a specific database with: String url = “jdbc:mysql://localhost/databasename”; String username = “test”; String password = “test”; Connection connection = DriverManager.getConnection(url, username, password);
I can confirm that I can connect to a MySQL database with SSL within Google Apps Script. It’s important to note useSSL=true is indeed necessary I was able to get it working by following the example at https://issuetracker.google.com/issues/36761592#comment18 (relevant snippet repeated below): var conn = Jdbc.getConnection(‘jdbc:mysql://<ip address>/<db name>?useSSL=true’, { user: ‘<user>’, password: ‘<pass>’, _serverSslCertificate: ‘—–BEGIN … Read more

Keeping the connection open for an undertemined time is a bad practice. The DB will force a close when it’s been open for a too long time. You should write your JDBC code so that it always closes the connection (and statement and resultset) in the finally block of the very same try block where … Read more
I think I’m qualified to answer, being the author of jOOQ, which was already suggested in another answer. As I’ve shown, it’s totally possible to achieve what you’re trying to do, but there is a long long road ahead for you, if you want to roll your own. Let’s talk about JDBC JDBC is an … Read more
You can definitely have a single config with multiple jdbc input and then parametrize the index and document_type in your elasticsearch output depending on which table the event is coming from. input { jdbc { jdbc_driver_library => “/Users/logstash/mysql-connector-java-5.1.39-bin.jar” jdbc_driver_class => “com.mysql.jdbc.Driver” jdbc_connection_string => “jdbc:mysql://localhost:3306/database_name” jdbc_user => “root” jdbc_password => “password” schedule => “* * * … Read more
I have set up a table with 4000 rows and 10 columns with 10 characters each and made a simple performance test using the following approach (RealTimeCounter is a class which measures the real time between start() and stop()): List<String> myResult = new ArrayList<>(); ResultSet rs = s.executeQuery(“SELECT * FROM Performance”); RealTimeCounter rtc = new … Read more
I’m using myBatis with Oracle. I guess there is something similar in other DB. Actually you always can create procedures in DB, which usually is better for the future, when you have to support the project. <delete id=”deleteUnfinishedData” parameterType=”map”> {call declare begin delete from TABLE1 where id = #{valueFromMap1}; delete from TABLE2 where id = … Read more
tl;dr myPreparedStatement.setObject( … , java.util.UUID.randomUUID() ) Details (a) Show us your code. PreparedStatement::setObject does work when passing a java.util.UUID. You likely have some other issue in your code. (b) See my blog post UUID Values From JDBC to Postgres for a bit of discussion and example code. // Generate or obtain data to store in … Read more
I find that a ScheduledExecutorService is an excellent way to do this. It is arguably slightly more complex than a Timer, but gives more flexibility in exchange (e.g. you could choose to use a single thread or a thread pool; it takes units other than solely milliseconds). ScheduledExecutorService executor = Executors.newSingleThreadScheduledExecutor(); Runnable periodicTask = new … Read more
