tGreenplumOutputBulk
Prepares the file to be used as parameter in the INSERT query to feed the Greenplum database.
The tGreenplumOutputBulk and tGreenplumBulkExec components are used together in a two step process. In the first step, an output file is generated. In the second step, this file is used in the INSERT operation used to feed a database. These two steps are fused together in the tGreenplumOutputBulkExec component, detailed in a separate section. The advantage of using a two step process is that it makes it possible to transform data before it is loaded in the database.
Writes a file with columns based on the defined delimiter and the Greenplum standards
