PL/SQL also has CASE expression which is similar to the CASE statement. A CASE expression evaluates a list of conditions and returns one of multiple possible result expressions. The result of a CASE expression is a single value whereas the result of a CASE statement is the execution of a sequence of Summary: in this tutorial, you will learn how to use the PL/SQL IF statement to either execute or skip a sequence of statements based on a specified condition.

In this chapter, we will discuss arrays in PL/SQL. The PL/SQL programming language provides a data structure called the VARRAY, which can store a fixed-size sequential collection of elements of the same type.A varray is used to store an ordered collection of data, however it is often better to think of an array as a collection of variables of the same type.

The result of a CASE expression is a single value whereas the result of a CASE statement is the execution of a sequence of In this tip we are going to compare the SQL Server (T-SQL) and Oracle (PL-SQL) extensions of the SQL language. The tip will compare both T-SQL and PL-SQL languages with respect to retrieving data, creating databases, tables, variables, etc. Solution.

It also has a large number of libraries which give it a great range of capabilties. However, undoubtedly its main use is building stored procedures which embed SQL statements for retrieving and working with data. So to that extent PL/SQL is a superset of SQL. The syntax is as follows: SELECT Column FROM Table; Oracle uses the ANSI standard concatenation operator, .

Dynamic SQL is a programming methodology for generating and running SQL statements at run time. It is useful when writing general-purpose and flexible programs like ad hoc query systems, when writing programs that must run database definition language (DDL) statements, or when you do not know at compilation time the full text of a SQL statement or the number or data types PL/SQL evaluates lower_bound and upper_bound once, when the FOR LOOP statement is entered, and stores them as temporary PLS_INTEGER values, rounding them to the nearest integer if necessary. If lower_bound equals upper_bound, the statements run only once.
