PL/SQL is a combination of SQL along with the procedural features of programming languages. It was developed by Oracle Corporation in the early 90's to enhance the capabilities of SQL. The PL/SQL Engine: Oracle uses a PL/SQL engine to processes the PL/SQL statements. A PL/SQL language code can be stored in the client system (client-side) or in the database (server-side) Exercises are designed to enhance your ability to write well-structured PL/SQL programs.

PL/SQL Function. The PL/SQL Function is very similar to PL/SQL Procedure. The main difference between procedure and a function is, a function must always return a value, and on the other hand a procedure may or may not return a value. Except this, all the other things of PL/SQL procedure are true for PL/SQL function too. Syntax to create a. PL/SQL is a modern, block-structured programming language. It provides several features that make developing powerful database applications very convenient. For example, PL/SQL provides procedural constructs, such as loops and conditional statements, that are not available in standard SQL For more working examples of Boolean values in PL/SQL see the code depot download in the book Easy Oracle PL/SQL Programming. Boolean values are great for checking complex evaluations in PL/SQL. A Boolean function can be wither a one (1) for TRUE and a zero (0) for FALSE: function false return boolean is begin return 0;. PL/SQL is more than SQL, which allows you to query, transform, update, design and debug data and provides more features than SQL.

In this Oracle PL/SQL tutorial, learn CASE and SEARCHED CASE Statement PL SQL Package. A package is an object in the form of a schema that segregates logically connected items, types, and subprograms in PL/SQL.

PL/SQL transaction is a series of SQL data manipulation statements that are work logical unit. Transaction is an atomic unit all changes either committed or rollback PL/SQL program unit. The main feature of SQL (non-procedural) is also a drawback of SQL: one cannot use control statements (decision-making or iterative control) if only SQL is to be used.PL/SQL is basically a procedural language, which provides the functionality of decision making, iteration and many more features like other procedural programming languages

This Oracle tutorial explains how to use the Oracle / PLSQL CASE statement with syntax and examples. The Oracle / PLSQL CASE statement has the functionality of an IF-THEN-ELSE statement.

Using PRINT command Like DBMS_OUTPUT statement print command also displays the current value of the bind variable except that you can write this command in host environment rather than inside any PL/SQL.
  3. Printing Variables Sometimes we might want to print the value of a PL/SQL local variable. A ``quick-and-dirty'' way is to store it as the sole tuple of some relation and after the PL/SQL statement print the relation with a SELECT statement. A more couth way is to define a bind variable, which is the only kind that may be printed with a print command. . Bind variables are the kind that must be.

It's no new feature in 11g but it's worth to describe it. Package DBMS_TRACE enables to trace execution of PL/SQL code in database.Oracle collects the trace data as the program executes and writes it to database tables.. Configuration. You must create database tables into which the DBMS_TRACE package writes output. Otherwise, the data is not collected Note: The demos on this page are intended to show valid syntax but it is far easier to use a hint to make a mess of things than it is to improve things. So many, if not most, of the demos will increase the cost. Join methods: In the loop join algorithm, an outer loop is formed that is composed of a few entries that are to be selected. Then, for each entry in the outer loop, a look-up is.

19.10. Examples. Here are only a few functions to demonstrate how easy it is to write PL/pgSQL functions. For more complex examples the programmer might look at the regression test for PL/pgSQL.. One painful detail in writing functions in PL/pgSQL is the handling of single quotes. The function's source text in CREATE FUNCTION must be a literal string DECODE function is used to perform procedural IF-THEN-ELSE logic in SQL. The function is a close relative of CASE statements. It is a built-in function in ORACLE / PL SQL database management servers. Recommended Articles. This is a guide to SQL DECODE(). Here we discuss how DECODE() function works in SQL with query examples for understanding.

Unlike SQL, PL/SQL is procedural, not declarative. This means that your code specifies exactly how things get done. As in SQL, however, you need some way to send your PL/SQL code up to the server for execution. PL/SQL also enables you to embed SQL statements within its procedural code XML-SQL Utility for PL/SQL. XMLDOM Package. The examples use the well known tables DEPT (the master table) and EMP (the detail table): Every employee has exactly one department assigned. One department has no, one, or more employees.
