Redo is not generated while performing conventional path loads.
Only PRIMARY KEY, UNIQUE KEY, and NOT NULL constraints are checked.
No exclusive locks are acquired when the conventional path loads are performed.
Instead of performing transactions, SQL*Loader directly writes data blocks to the data files.

第2题:
Which two statements are true about constraints? ()
第3题:
Which two statements are true about a bitmap index? ()
第4题:
Which statement is true about loading data using the conventional path of SQL*Loader()
第5题:
You are using flat files as the data source for one of your data warehousing applications. You plan to move the data from the flat file structures to an Oracle database to optimize the application performance. In your database you have clustered tables. While migrating the data, you want to have minimal impact on the database performance and optimize the data load operation. Which method would you use to load data into Oracle database?()
第6题:
Which of the following choices correctly describes the difference between a data load via the conventional path and the direct path?()
第7题:
Redo is not generated while performing conventional path loads.
Only PRIMARY KEY, UNIQUE KEY, and NOT NULL constraints are checked.
No exclusive locks are acquired when the conventional path loads are performed.
Instead of performing transactions, SQL*Loader directly writes data blocks to the data files.
INSERT triggers are disabled before the conventional path load and reenabled at the end of the load.
第8题:
The constraint remains valid.
The index on the constraint is dropped.
It allows the loading of data into the table using SQL *Loader.
New data conforms to the constraint, but existing data is not checked.
It allows the data manipulation on the table using INSERT/UPDATE/DELETE SQL statements.
第9题:
Use the external table population.
Use the Oracle Data Pump export and import utility.
Use the conventional path data load of the SQL*Loader utility.
Use the INSERT INTO...SELECT command to load the data
第10题:
The UNIQUE constraint does not permit a null value for the column.
A UNIQUE index gets created for columns with PRIMARY KEY and UNIQUE constraints.
The PRIMARY KEY and FOREIGN KEY constraints create a UNIQUE index.
The NOT NULL constraint ensures that null values are not permitted for the column.
第11题:
It is not possible to disable the primary key constraint.
It is possible to have more than one primary key constraint in a single table.
The primary key constraint can be referred by only one foreign key constraint.
The primary key constraint can be imposed by combining more than one column.
The non-deferrable primary key constraint creates an unique index on the primary key column if it is not already indexed.
第12题:
One runs faster than the other
A conventional path data load bypasses most of the Oracle RDBMS, whereas a direct path load is a high-speed version of the SQL INSERT
A direct path data load bypasses most of the Oracle RDBMS, whereas a conventional path load is a high-speed version of the SQL INSERT
The conventional path runs when the CONVENTIONAL command-line parameter is set to TRUE
第13题:
Which two statements are true about the primary key constraint in a table? ()
第14题:
Which two statements about the SQL Management Base (SMB) are true? ()(Choose two.)
第15题:
In which two scenarios do you use SQL* Loader to load data?()
第16题:
You plan to move data from a flat file to a table in your database. You decide to use SQL*Loader direct pathload method to perform this task. The table in which you plan to load data is an important table having variousintegrity constraints defined on it. Which constraints will remain enabled by default during this operation()
第17题:
Which statement is true about loading data using the conventional path of SQL*Loader()
第18题:
Examine the following statement that is used to modify the primary key constraint on the SALES table: SQL> ALTER TABLE SALES MODIFY CONSTRAINT pk DISABLE VALIDATE; Which three statements aretrue regarding the above command()
第19题:
Redo is not generated while performing conventional path loads.
Only PRIMARY KEY, UNIQUE KEY, and NOT NULL constraints are checked.
No exclusive locks are acquired when the conventional path loads are performed.
Instead of performing transactions, SQL*Loader directly writes data blocks to the data files.
INSERT triggers are disabled before the conventional path load and reenabled at the end of the load
第20题:
Use the external table population.
Use the Oracle Data Pump export and import utility.
Use the conventional path data load of the SQL*Loader utility.
Use the INSERT INTO...SELECT command to load the data.
第21题:
The PRIMARY KEY is created along with a new index.
The PRIMARY KEY is created and it would use an existing unique index.
The PRIMARY KEY would be created in a disabled state because it is using an existing index.
The statement produces an error because the USING clause is permitted only in the CREATE TABLE command.
第22题:
use the external table population
use the Oracle Data Pump export and import utility
use the conventional path data load of SQL*Loader utility
use the direct path data load of Oracle export and import utility
