an empty string. For all other types, a field containing only white space is rejected and the
record is written to the

“baddatafile” (page 47)

file.

For an extract operation:

•

This option specifies the character string that should be written to targets to represent NULL
values.

•

For delimited data formats, if nullstring is not specified, Transporter does not write any
data characters to the target field to represent a NULL value.

•

For fixed-width data formats, if nullstring is not specified, Transporter rejects any
retrieved record containing NULL values and writes the record to the baddatafile file.

operation

operation = "insert" | "update" | "upsert"

The default is “insert”.

For a load operation, this option specifies the type of Neoview SQL operation to be performed:

•

“insert”

— inserts data into a Neoview SQL table

•

“update”

— updates data in a Neoview SQL table

•

“upsert”

— updates data in a Neoview SQL table if the data exists, otherwise inserts data

This option is ignored for extract operations.

parallel

parallel = "true" | "false"

“true”

— all job entries of a given job execute in parallel

“false”

— all job entries of a given job execute serially

The default is “false”.

parallelstreams

parallel = number

This option specifies the number of data connections Transporter establishes for accessing the
Neoview database.

number

must be an integer greater than or equal to one.

For a load operation or a TABLE extract operation:

•

Transporter internally limits the maximum value of parallelstreams to the number of
partitions for the table.

•

If this option is not specified, Transporter establishes one data connection for every four
partitions of the table.

For a Neoview SQL extract operation:

•

Transporter internally limits the maximum value of parallelstreams to the number of
CPUs on the Neoview system.

•

If this option is not specified, Transporter establishes one data connection for every four
CPUs on the Neoview system.
