SAMPLE SAMPLE=[[schema_name.]table_name:]sample_percent
Allows you to
specify a percentage of the data rows to be sampled and unloaded from the
source database.
This parameter allows you to export subsets of data
by specifying the percentage of data to be sampled and exported. The
sample_percent indicates the probability that a row will be selected as part of
the sample. The sample_percent can be applied to specific tables. In the
following example, 50% of the HR.EMPLOYEES table will be exported:
SAMPLE="HR"."EMPLOYEES":50
If you specify a schema, then you must also specify a
table. However, you can specify a table without specifying a schema; the
current user will be assumed. If no table is specified, then the sample_percent
value applies to the entire export job.
