Correct Option: C

You need to read data from three oracle tables that store sales data from three regions to load into a single oracle table. These three tables are having the same table definitions and the only difference is that each table contains data for a particular region. Which of the following will do the required task?

  1. Create a task with single oracle enterprise stage that executes a custom SQL statement with FETCH ALL, that outputs to an Oracle enterprise stage.

  2. Create a job with three Oracle Enterprise stages to read from the tables and output to a collector stage which in turn outputs the data to an Oracle Enterprise stage.

  3. Create a job with a single Oracle Enterprise stage that executes a custom SQL statement with UNION ALL that outputs the data to an oracle enterprise stage.

  4. Create a job with three Oracle Enterprise stages to read from the tables and output to a Funnel stage which in turn outputs the data to an oracle enterprise stage.


Correct Option: C,D

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Create a task with a single Oracle Enterprise stage that executes a custom SQL statement with FETCH ALL, that outputs to an Oracle Enterprise stage.

This option is incorrect because using FETCH ALL in a custom SQL statement will only fetch all rows from a single table, not from multiple tables.

Option B) Create a job with three Oracle Enterprise stages to read from the tables and output to a collector stage which in turn outputs the data to an Oracle Enterprise stage.

This option is incorrect because using a collector stage will not combine the data from the three tables into a single table. It will only collect the data from each table separately.

Option C) Create a job with a single Oracle Enterprise stage that executes a custom SQL statement with UNION ALL that outputs the data to an Oracle Enterprise stage.

This option is correct because using UNION ALL in a custom SQL statement will combine the data from the three tables into a single result set. The Oracle Enterprise stage can then output this combined data to a single table.

Option D) Create a job with three Oracle Enterprise stages to read from the tables and output to a Funnel stage which in turn outputs the data to an Oracle Enterprise stage.

This option is correct because using a Funnel stage will combine the data from the three Oracle Enterprise stages into a single stream. The combined data can then be output to an Oracle Enterprise stage to load into a single table.

The correct answer is C, D. These options will allow you to read data from the three Oracle tables and load it into a single Oracle table. Option C uses UNION ALL in a custom SQL statement, while Option D uses a Funnel stage to combine the data.

How could repetition element identified on an XML input stage, which is processing an XML file?

  1. Auto detect by XML stage.

  2. Check the "Repetition Element Required" box on the output link tab.

  3. Set the key property for the column on the output link to 'Yes'

  4. Set the 'Nullable' property for the column on the output link to 'Yes'


Correct Option: C

AI Explanation

To identify repetition elements in an XML input stage while processing an XML file, the correct option is C) Set the key property for the column on the output link to 'Yes'.

Here's an explanation for each option:

Option A) Auto detect by XML stage - This option is incorrect because the XML stage does not have an automatic detection feature for repetition elements.

Option B) Check the "Repetition Element Required" box on the output link tab - This option is incorrect because there is no "Repetition Element Required" box on the output link tab. This option is not applicable.

Option C) Set the key property for the column on the output link to 'Yes' - This option is correct. By setting the key property for a column on the output link to 'Yes', you are indicating that the column represents a repetition element in the XML file.

Option D) Set the 'Nullable' property for the column on the output link to 'Yes' - This option is incorrect. The 'Nullable' property is used to indicate whether a column allows null values or not, and it is not directly related to identifying repetition elements in an XML file.

Therefore, the correct answer is C) Set the key property for the column on the output link to 'Yes'.

  1. Call the DSLoggFatal function from a stage variable derivation

  2. Call the DSStopJob function from a stage or column derivation

  3. Use the SETENV function to set the environmental variable APT_PM_KILL_NOWAIT

  4. Create a dummy output link with a constraint that tests for the condition to abort on; set the 'Abort After rows' property to 1


Correct Option: D
