PLSQL FAQs
What is Advanced PL/SQL and how does it differ from basic PL/SQL?
Advanced PL/SQL builds upon the foundation of basic PL/SQL by introducing more complex features such as dynamic SQL, bulk operations (bulk collect and bulk bind), advanced exception handling, packages, and advanced data structures like collections. These features allow for more efficient processing, better performance tuning, and enhanced control over database operations
What are PL/SQL packages and why are they important?
PL/SQL packages are collections of related procedures, functions, variables, and other elements grouped together in a single unit. They provide modularity, reusability, and better organization of code, which simplifies maintenance and improves performance by reducing the need for recompilation of code.
How does bulk collect improve performance in PL/SQL?
Bulk collect allows fetching multiple rows from a query into a PL/SQL collection in a single operation, reducing context switches between the SQL and PL/SQL engines. This dramatically improves performance when working with large datasets, as it minimizes the number of interactions required to fetch data.
What is the difference between implicit and explicit cursors in PL/SQL?
Implicit cursors are automatically created by Oracle for single SQL statements like SELECT INTO, while explicit cursors are user-defined and allow for more control when handling query results. Explicit cursors are typically used when dealing with queries that return multiple rows.
What is dynamic SQL in PL/SQL and when would you use it?
Dynamic SQL is used to execute SQL statements that are built at runtime rather than being hard-coded. It is useful when the exact SQL query is not known until runtime, such as in cases where the query structure changes based on user input or other runtime variables.
How does exception handling work in Advanced PL/SQL?
Exception handling in PL/SQL allows developers to define how their program responds to runtime errors. Advanced PL/SQL offers better control over error handling with predefined exceptions, user-defined exceptions, and the ability to propagate or handle exceptions using the RAISE statement.
What is a mutating table error and how can it be resolved in PL/SQL?
A mutating table error occurs when a trigger tries to modify or query the table that caused the trigger to fire. This can be resolved by using compound triggers or by creating a separate procedure to handle the data modifications outside the context of the trigger, thus avoiding direct access to the table during its modification.
What are collections in PL/SQL and what are their types?
Collections in PL/SQL are data structures that can store multiple values. The three main types of collections are associative arrays (index-by tables), nested tables, and varrays (variable-sized arrays). They are useful for storing and manipulating sets of data in memory.
What is the purpose of the FORALL statement in PL/SQL?
The FORALL statement is used for bulk binding in PL/SQL to execute the same DML operation (INSERT, UPDATE, DELETE) on a collection of values in one go. It helps improve performance by minimizing context switches between SQL and PL/SQL engines during bulk operations.
How do you manage security in PL/SQL using definer’s rights and invoker’s rights?
Definer’s rights means that the PL/SQL code executes with the privileges of the user who defined the object (e.g., procedure, function), while invoker’s rights execute with the privileges of the user who invoked the code. This allows for flexible control over database access and security management.
How can PL/SQL code be optimized for better performance?
PL/SQL code can be optimized by using techniques such as bulk collect and FORALL to minimize context switches, writing efficient SQL queries, using indexes appropriately, avoiding unnecessary cursors or loops, and implementing proper exception handling. Code profiling and tracing tools can also help identify performance bottlenecks.
What is the purpose of autonomous transactions in PL/SQL?
An autonomous transaction is a separate transaction that can commit or roll back independently of the main transaction. It is used in scenarios where an action, such as logging or auditing, needs to be saved to the database, even if the main transaction fails.
What is the difference between a procedure and a function in PL/SQL?
A procedure performs an action but does not return a value, while a function performs a specific task and returns a value. Functions are typically used for computations and can be used in SQL statements, whereas procedures are used for more complex operations that may not necessarily return a result.
How do you use triggers in PL/SQL and what are their limitations?
Triggers are PL/SQL blocks that automatically execute in response to certain events on a table, such as INSERT, UPDATE, or DELETE. They are used to enforce business rules, maintain audit trails, or replicate data. However, triggers can cause performance issues if overused or if they lead to mutating table errors.
What is dynamic PL/SQL and how does it differ from static PL/SQL?
Dynamic PL/SQL refers to PL/SQL code that generates and executes SQL statements at runtime using the EXECUTE IMMEDIATE or DBMS_SQL package, allowing for greater flexibility in handling different scenarios. In contrast, static PL/SQL is compiled at the time of coding and cannot adapt to changing requirements at runtime.
