4/27/2024 0 Comments Dbeaver create table scriptLet’s try to write and execute a couple of simple queries to demonstrate the essential features of the SQL editor. For example, to convert a case, you need to select a part of the script, right-click and go to Format -> Upper case or Format -> Lower case.This feature can be useful when dealing with case-sensitive databases. The SQL editor also has a right-click context menu with a lot of options. For example, here you can change the work of the code completion which is one of DBeaver’s most useful and convenient features. Here you can change the formatting, script processing settings, and more. To do this, click on the gear icon and go to Editors -> SQL Editor. You can change the editor settings according to your personal needs. The editor highlights keywords, which is especially useful for large scripts.ĭifferent databases have different sets of reserved keywords and system functions, so highlighting depends on the database associated with the script. By default, each new script will open in a new tab, which you can change if you want. You can use the SQL Editor for executing full scripts and single queries like SELECT, INSERT, DROP etc. For example, you can set up a quick opening of the console by clicking on this button. The SQL button above the Navigation tree allows you to open SQL scripts, as well as change the default command. As scripts written this way are not saved in a file format, in some cases console is faster and more convenient to use. Many of our users prefer to write scripts in the SQL console, which is a possibility DBeaver provides. If you have not selected a specific database, a window will appear which will prompt you to choose a connection. To create a new SQL script or to open an existing one, go to the main menu, click SQL Editor and select an appropriate option. With the SQL Editor you can write and execute scripts, save them as files and reuse them later. Today we are going to tell you about its main features. The existing open source adapters provided by Exasol can be accessed from the Exasol GitHub Repository.SQL Editor is a powerful tool for creating and executing various SQL scripts.For more information about adapter scripts and virtual schemas, refer to the Virtual Schemas section.Adapter scripts can only be implemented in Java, Lua, and Python.You can also specify this clause in the function call within a SELECT statement. If you define the ORDER BY clause in the parameter list, the groups of the SET input data are processed in an ordered way.For more information, refer to UDF scripts section. You can also implement the MapReduce algorithms. In addition to scalar functions, you can also create aggregate and analytic functions.UDF scripts can be used directly within SELECT statements and can process big data volumes.For more information, refer to the Return Value of a Script section. If neither of the two options RETURNS TABLE and RETURNS ROWCOUNT is specified, the option RETURNS ROWCOUNT is implicitly used.Lua is the supported programming language for scripting programs.For more information, refer to the Scripting section. Scripting programs provide a way to control the execution of several SQL commands (for example, for ETL jobs) and are executed with the EXECUTE SCRIPT command.If you want to further integrate script languages for user-defined functions and adapter scripts, refer to the Expanding Script Languages Using BucketFS section. The content of a script is integrated in the corresponding system tables (for example EXA_ALL_SCRIPTS).The option OR REPLACE can be used to replace an existing script without having to explicitly delete it with DROP SCRIPT.
