Schema and Edit Schema |
A schema is a row description. It defines the number of fields (columns) to be processed and passed on to the next component. The schema is either Built-In or stored remotely in the Repository. Since version 5.6, both the Built-In mode and the Repository mode are available in any of the Talend solutions. |
|
|
Built-in: The schema is created and stored locally for this component only. Related topic: see Talend Studio User Guide. |
|
|
Repository: The schema already exists and is stored in the Repository, hence can be reused. Related topic: see Talend Studio User Guide. |
Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

Attribute table |
Set the position value of each column for single records from the recordset. |
Global Variables |
NB_LINE: the number of rows processed. This is an After variable and it returns an integer. 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. To fill up a field or expression with a variable, press Ctrl + Space to access the variable list and choose the variable to use from it. For further information about variables, see Talend Studio User Guide. | |
