Oracle Database Administration from Zero to Hero - Using SQL Loader (Part 4 of 4)

The video tutorial covers advanced SQL Loader concepts, including field definitions, SYSDATE parameter, sequence numbers, and handling filler fields. It explains the differences between conventional, direct path, and external table loading methods. The tutorial also highlights the use of case study files for practical learning.

What does the SYSDATE parameter do in SQL Loader?

• It assigns a fixed date to all rows.

• It retrieves the current database date and time.

• It converts character data to date format.

• It generates a unique identifier for each row.

How does SQL Loader handle the job code column when it contains only spaces?

• It converts spaces to underscores.

• It leaves the column unchanged.

• It sets the job code to NULL.

• It removes the spaces.

Which function is used to ensure all inserted data is in uppercase?

• UPPER

• INITCAP

• CAPITALIZE

• LOWER

What is the purpose of the sequence parameter in SQL Loader?

• To generate unique sequence numbers.

• To sort data before loading.

• To convert data formats.

• To validate data types.

What does the COUNT keyword do when used with the sequence parameter?

• Starts the sequence from a specified integer.

• Starts the sequence from the maximum value in the column.

• Starts the sequence from the total number of records.

• Starts the sequence from zero.

How can SQL Loader skip columns that do not correspond to any database column?

• By using the IGNORE clause.

• By marking them as filler fields.

• By setting them to NULL.

• By using the SKIP clause.

What is the advantage of using the direct path loading method?

• It is the default method.

• It is faster than the conventional method.

• It supports all loading scenarios.

• It requires no configuration.

What is a key feature of external table loads?

• They do not support SQL functions.

• They are slower than conventional loads.

• They are saved inside the database tablespace.

• They allow parallel loading of large files.

Where can you find case study files for SQL Loader?

• In the Oracle Database Examples product.

• In the Oracle Database Utilities documentation.

• In the Oracle HOME/RDBMS/demo directory.

• In the SQL Loader installation directory.

What type of files are included in the SQL Loader case studies?

• SQL, CTL, and DAT files.

• Only DAT files.

• Only SQL files.

• Only CTL files.
