Use an existing
connection

Select this check box and in the Component List click the relevant connection component to
reuse the connection details you already defined.

This component supports Neo4j version V3.2.X only and does not support the remote mode. Therefore, do not reuse the connection to versions other than V3.2.X defined in a tNeo4jConnection component and do not select the Remote server check box in tNeo4jConnection.

Do
not use a 2.X.X version and a 3.X.X version in the same Job. Otherwise,
class conflict issues occur.

Database path

This field
appears only if you do not select the Use an
existing connection check box.

Shutdown after
job

Select this check box to shutdown the Neo4j database connection when no more
operations on Neo4j are going to be performed after the current
component.

Alternatively, you can use tNeo4jClose to shutdown the
database.

This avoids errors such as “Id file not properly shutdown” at next execution
of Jobs involving Neo4j.

This check box is available only if the Use an existing
connection check box is not selected.

as well as at each component level.

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.
