Job Example 7: Mini-Batch Loading
Read data directly from one or more external flat files and write it to a Teradata Database table.
Note: This job represents a special case of high speed loading, where the destination table is already populated, or has join indexes or other restrictions that prevent it from being accessed by the Load operator. Because of this, the job includes an intermediate step that loads the data into a staging table and then uses the DDL operator with INSERT…SELECT to move the data into the final destination table.
