tHL7Input reads an HL7 structured file and extracts data row by row.


Opens an HL7 structured file and reads it row by row to split them up into fields then sends the fields as defined in the Schema to the next component, via a Row link.

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.

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.


Usually used as a Start component. An output component is required.
