  2. java - Finding Installed JDBC Drivers - Stack Overflow

    stackoverflow.com/questions/1839671

    As the doc says. Retrieves an Enumeration with all of the currently loaded JDBC drivers to which the current caller has access. That means loaded drivers (with Class.forName ()), not installed (say available thru a JAR). Normally you would deliver your software with all JDBC driver jars that your program can work.

  3. Connecting and testing a JDBC driver from Python

    stackoverflow.com/questions/46353440

    1. I'm trying to do some testing on our JDBC driver using Python. Initially figuring out JPype, I eventually managed to connect the driver and execute select queries like so (reproducing a generalized snippet): from __future__ import print_function from jpype import * #Start JVM, attach the driver jar jvmpath = 'path/to/libjvm.so' classpath ...

  4. 2. You need to add the JAR file containing the JDBC driver to the runtime classpath. The linked answer explains that in detail. If you're using an IDE, just add JAR file as Library to Build Path. If you're using java.exe, then you need to specify its path in -cp argument.

  5. Compatibility of JDBC driver with Oracle 19c Database

    stackoverflow.com/questions/74374087/compatibility-of-jdbc-driver-with-oracle...

    We are currently using ojdc14(Java 1.6) with Oracle 11g Database and want to upgrade the DB to 19c version. I wanted to know which ojdbc jars are compatible with Oracle 19c database?

  6. java - About JDBC drivers - Stack Overflow

    stackoverflow.com/questions/9575367

    Newer JDBC drivers now register themselves automatically. You can't tell just by looking at the code that uses it (that's the whole point), but the mysql jdbc driver is a type 4 driver. As you can't tell the difference by using the driver, the sample code to use a type 2 driver is the same as what you've provided in the question.

  7. The four types are: Type 1: JDBC-ODBC Bridge driver (Bridge) Type 2: Native-API/partly Java driver (Native) Type 3: AllJava/Net-protocol driver (Middleware) Type 4: All Java/Native-protocol driver (Pure) They will have different performance characteristics.

  8. JDBC Class.forName vs DriverManager.registerDriver

    stackoverflow.com/questions/5484227

    The JDBC spec requires a driver to register itself when the class is loaded, and the class is loaded via Class.forName (). In JDBC 4 the drivers are able to be loaded automatically just by being on the class path. DriverManager.registerDriver () manually is potentially dangerous since it actually causes the Driver to be registered twice.

  9. The Oracle JDBC drivers are now available in Maven Central. Here is the Link: Oracle JDBC Drivers - Maven Central. Oracle developers article announcing the availability of the Oracle JDBC drivers in Maven Central: Oracle announcing - Oracle JDBC drivers available in Maven Central. Example:

  10. In order to include the driver for postgresql you can do the following: from pyspark.conf import SparkConf conf = SparkConf() # create the configuration conf.set("spark.jars", "/path/to/postgresql-connector-java-someversion-bin.jar") # set the spark.jars ... spark = SparkSession.builder \ .config(conf=conf) \ # feed it to the session here .master("local") \ .appName("Python Spark SQL basic ...

  11. communication - How does jdbc work - Stack Overflow

    stackoverflow.com/questions/2716733

    10. Communication with the database is handled by JDBC drivers that can use various strategies to "talk" to a database (from "translation" to the use of "native" language). Depending on the strategy used, drivers are categorized into 4 types. Types of JDBC technology drivers provide a good description of each of them:
