are a Java developer and you are thinking about extending Exasol with new functionality, this tutorial takes you on a tour around Exasol's interfaces and the libraries we provide.\n\nNot only do you learn how to implement [User Defined Functions (UDF)](https://docs.exasol.com/database_concepts/udf_scripts.htm) in Java, but you also will see how to run automated integration tests.\n\nTopics we are touching in the tutorials:\n\n* Scalar Script UDF (a script with a single input)\n* Java code inlined into SQL code\n* Java UDFs provided as JAR archives\n* Exasol Scripting API for Java\n* How to get an Exasol instance you can test against in automated tests\n* How to set up tests and prepare test data\n* How to check the results from SQL queries in a compact and readable way\n\n## Tutorials\n\n### Hello World!\n\nStart your journey with the obligatory [hello world](hello-world-tutorial/doc/hello_world.md) tutorial to learn the basics of defining an inline Java extension that can be called from SQL.\n\n## Markdown Statistics as User Defined Function\n\nUp your game with a full-blown automated integration test that exercises a more complex Java extension that gets [statistics from Markdown](markdown-statistics-tutorial/doc/mdstats.md) text stored in an Exasol table. Learn to package the installation in a JAR archive in the course of this tutorial.\n\n## TLS Tutorial\n\nSetting up TLS is all but trivial in some scenarios, so a series of articles and some software examples guide you through the process.\n\n1. [Introduction to TLS](tls-tutorial/doc/tls_introduction.md)\n2. [TLS with Exasol (theoretical part)](tls-tutorial/doc/tls_with_exasol.md)\n3. [Using Your Own Certificates](tls-tutorial/doc/use_your_own_certificate.md) to run `IMPORT` from MySQL into Exasol\n4. [TLS in User Defined Functions (UDFs)](tls-tutorial/doc/tls_in_udfs.md)\n\n## Java Testing Tutorial\n\n* [Introduction](testing-tutorial/doc/introduction.md)\n* [Tests are an Executable Specification](testing-tutorial/doc/test_are_an_executable_specification.md)\n* [Automatic Testing](testing-tutorial/doc/automatic_testing.md)\n* [Test Driven Design and Behavior Driven Design](testing-tutorial/doc/tdd/tdd_and_bdd.md)\n* [Multiple Asserts in one Test Case](testing-tutorial/doc/multiple_asserts_in_one_test_case.md)\n* [Dealing with Randomness](testing-tutorial/doc/dealing_with_randomness.md)\n\n## Additional Information\n\n* [Changelog](doc/changes/changelog.md)\n* [Dependencies](dependencies.md)\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fexasol%2Fexasol-java-tutorial","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fexasol%2Fexasol-java-tutorial","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fexasol%2Fexasol-java-tutorial/lists"}
