Copy Over

You are looking at an older version of the documentation. The latest version is found here.

The CopyOver method retrieves the current data from a given source and puts it into the local table. If a table with the same name already exists, it will be handled according to the selected cleanup method.

source_table

DROP (table will be dropped and recreated); default
DELETE (table will be emptied via deletion of all rows)

PIPES_PREFER_DROP not set and cleanup_method not set => DROP
PIPES_PREFER_DROP set and cleanup_method not set => PIPES_PREFER_DROP
PIPES_PREFER_DROP not set and cleanup_method set => cleanup_method

CopyOver Jobs

In addition to the CopyOver() method, the Data Virtuality Server also allows using the CopyOver technique on data sources via two procedures:

createCopyOverSourceTableJob()
createCopyOverSQLJob()

For changing existing CopyOver jobs, two more procedures are available:

changeCopyOverSourceTableJob()
changeCopyOverSQLJob()
