Lesson Objectives

Oracle Database 11g: Packages, Dynamic SQL, and Coding Considerations

recognize the steps for overloading subprograms, using forward declarations, writing package initialization blocks, and maintaining persistent package state.

identify the steps for using the Oracle-supplied packages DBMS_OUTPUT, UTL_FILE, and UTL_MAIL.

recognize the steps for using Oracle-supplied packages to generate a simple Web page and schedule PL/SQL code for execution.

identify the steps for constructing and executing SQL statements at run time, using native dynamic SQL statements in PL/SQL.

alter a package so that it contains overloaded subprograms, use an Oracle-supplied package, and execute dynamic SQL in a given scenario.

identify the steps for designing packages so that code is easy to maintain, efficient, and readable, and so that PL/SQL applications perform better.

Identify the steps for binding whole arrays of values in a single operation, and for retrieving information about a row affected by a SQL operation.
