题目：
98. Which two statements are true regarding the usage of the SQL*Loader utility? (Choose two.)
A.You can load data into multiple tables during the same load session.
B.You can load data from multiple files to a table during the same load session.
C.You cannot perform selective data loading based on the values available in the records.
D.You can use an export file generated by the EXPDP utility as an input data file to load the data.
E.You can load data only if the input file is available on the disk and tape but not in a named pipes.
参考答案 AB
解析
题目意思问，哪两个SQL Loader的特性是正确的。
在同一个加载会话期间将数据加载到多个表中。 所以A正确
在同一个加载会话期间从多个数据文件加载数据。所以B正确
有选择地加载数据（您可以根据记录的值加载记录）。所以C错误。
SQLLoader针对的是平面文件，而expdp数据泵程序出来的是二进制文件。所以D错误。
从磁盘，磁带或命名管道加载数据 。所以E错误。

SQL*Loader Features
SQL*Loader loads data from external files into tables of an Oracle database. It has a powerful data parsing engine that puts little limitation on the format of the data in the data file. You can use SQL*Loader to do the following:
-
Load data across a network if your data files are on a different system than the database. (See Loading Data Across a Network)
-
Load data from multiple data files during the same load session.
-
Load data into multiple tables during the same load session.
-
Specify the character set of the data.
-
Selectively load data (you can load records based on the records' values).
-
Manipulate the data before loading it, using SQL functions.
-
Generate unique sequential key values in specified columns.
-
Use the operating system's file system to access the data files.
-
Load data from disk, tape, or named pipe.
-
Generate sophisticated error reports, which greatly aid troubleshooting.
-
Load arbitrarily complex object-relational data.
-
Use secondary data files for loading LOBs and collections.
-
Use either conventional or direct path loading. While conventional path loading is very flexible, direct path loading provides superior loading performance. See Chapter 12.
A typical SQL*Loader session takes as input a control file, which controls the behavior of SQL*Loader, and one or more data files. The output of SQL*Loader is an Oracle database (where the data is loaded), a log file, a bad file, and potentially, a discard file. An example of the flow of a SQL*Loader session is shown in Figure 7-1.
