  1. Use a Column Exporter to perform the type conversion.

  2. DataStage handles the type conversion automatically

  3. Use the TimestampFromDateTime function in a Transformer.

  4. Use the Modify stage to perform the type conversion.

Correct Option: D

AI Explanation

To answer this question, we need to understand how DataStage handles type conversion when mapping a VARCHAR field to a date field.

Option A) Use a Column Exporter to perform the type conversion. This option is incorrect because a Column Exporter is used to export data from DataStage to an external target, not for performing type conversions within DataStage itself.

Option B) DataStage handles the type conversion automatically. This option is incorrect because DataStage does not automatically handle type conversions. It is important to explicitly convert data types to ensure accurate mapping and processing.

Option C) Use the TimestampFromDateTime function in a Transformer. This option is incorrect because the TimestampFromDateTime function is used to convert a DateTime field to a Timestamp field, not a VARCHAR field to a date field.

Option D) Use the Modify stage to perform the type conversion. This option is correct because the Modify stage in DataStage allows for data transformation and type conversion. By using the Modify stage, you can convert the VARCHAR field to a date field.

The correct answer is D) Use the Modify stage to perform the type conversion. This option is correct because the Modify stage can be used to convert the VARCHAR field to a date field.
