Created this content a decade ago as I joined with IFS.

1. Best Practices in PL/SQL

2. Why Do we Need to follow
Best Practices???
• Good practices help to ensure that code is
developed properly
• Best practices help to ensure that code is in a
maintainable fashion

4. SPOD
• SPOD is well known as “Single Point of
definition”
• SPOD simply implies that define once and use
every where!!!!
• Therefore, developer does not need to repeat
the code.

5. Explicit Vs Implicit
• Use Explicit cursors as much as possible in
code.
• Avoid to use ‘select’ implicit cursor
• Nevertheless, Steven Feuerstein has
recommended to use implicit cursor in the
code.
• BUT in IFS context, ‘Explicit’ cursors are
recommended!!!

6. Avoid!!
• Avoid Hard coding
• Avoid to use VARCHAR2(N) declaration
• Avoid to use ‘Literal’ value. But, use
name%type or name%rowtype

7. Data encapsulation

8. Data encapsulation
• Hide business rules and formulas!
• Move blocks of complex code such as Function
and Procedure
• Write small, Narrowly focused code
easy to reuse package

10. Error Handling
• Handles the errors separately and have
package for that
