Schema and Edit schema

A schema is a row description, it defines the number of fields to be processed and passed on to the next component. The schema is either Built-in or stored remotely in the Repository.

Built-in: You create and store the schema locally for this component only. Related topic: see Talend Studio User Guide.

Repository: You have already created the schema and stored it in the Repository and thus reuse it when needed. Related topic: see Talend Studio User Guide.

Table Name

Enter the name of the table to be read.

Where clause

Enter a WHERE clause to define a row filter on the table.

You can use the WHERE clause to filter the rows you want to analyze in the table. This WHERE clause enables you then to retrieve valid and invalid data that match certain specified criteria or conditions.

Global Variables

NB_LINE: the number of rows read by an input component or transferred to an output component. This is an After variable and it returns an integer.

QUERY: the query statement being processed. This is a Flow variable and it returns a string.

ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.
