The design workspace in Talend Studio allows the user to graphically connect components in a Job to run a dataflow process. The design workspace is the main area where the user can design the data integration logic by dragging and dropping components from the palette and linking them with connectors. The design workspace also shows the schema of each component, which defines the structure and type of the data.

The tMap component allows you to configure multiple outputs for your data transformation and mapping. You can apply filter expressions on each output to filter out the rows that meet certain criteria. For example, if you want to send only the rows that have CA as the state value to one output, you can use CA.equals(row1.state) as the filter expression for that output. The filter expression evaluates to true or false for each row, and only the rows that evaluate to true are sent to the output. In this case, only Thomas Coolidge and Andrew Taylor have CA as their state value, so they are sent to the CA output. Similarly, only Calvin Adams has NY as his state value, so he is sent to the NY output. The Rejects output has no filter expression, so it receives all the rows from the input by default. However, since there is a conflict between the CA and NY outputs and the Rejects output, only the rows that are not sent to any other output are sent to the Rejects output. In this case, there are no such rows, so the Rejects output receives no data. References: Talend Open Studio: Open-source ETL and Free Data Integration | Talend,

To trigger auto-completion in Talend Studio, you can use the keystrokes Ctrl + Space. This will display a list of possible suggestions based on what you have typed so far. For example, if you type context. and press Ctrl + Space, you will see a list of all the context variables you have defined. You can then select the one you want from the list or continue typing to narrow down the choices. Auto-completion can help you avoid typing errors and save time when configuring components or writing expressions. References: Talend Open Studio: Open-source ETL and Free Data Integration | Talend

Talend Studio provides two types of SQL templates: system SQL templates and user-defined SQL templates. SQL templates are predefined SQL queries that can be used in various components that execute SQL statements, such as tDBInput, tDBRow, tDBOutput, etc. System SQL templates are provided by Talend Studio and cover common SQL operations, such as creating, dropping, or altering tables, inserting, updating, or deleting data, etc. User-defined SQL templates are created by the user and can be customized according to specific needs. User-defined SQL templates can be created by using the SQL Templates view in Talend Studio and can be organized into categories and subcategories. There are no custom SQL templates orsystem-defined SQL templates in Talend Studio. References: Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [SQL Templates - 7.3]

You need to use the following code in a tJava component to write a nb_line variable:

int nb_line = (Integer)globalMap.get(“tFileInputDelimited_1_NB_LINE”);

This code retrieves the value of the global variable tFileInputDelimited_1_NB_LINE, which stores the number of rows processed by the tFileInputDelimited component, and assigns it to an integer variable named nb_line. You can then use this variable to print or manipulate the number of rows in your Job. Note that you need to use globalMap.get, not globalMap.put, to access the value of a global variable.
