Oracle SQL Tutorial – Downloading Oracle Database and Installing SQL Developer.Configure the connection to the server and database.built-in SYS_CONNECT_BY_PATH function for ordered concatenation of received numbers.pseudo table level to create a pseudo table t1 containing numbers from 1 to 16.Bine formula and mathematical functions ROUND, POWER and SQRT to calculate the n-th Fibonacci number.SQL does not support cycles or recursions, and concatenation of fields from different rows in a table or query is not a standard aggregate function. Line “0! = 1” will not be included in the result set of strings, because an attempt to calculate ln(0) leads to an exception. and mathematical functions ln and exp, allowing to replace the work (necessary for calculating the factorial) with the sum (provided by SQL).the aggregate function sum, which allows you to sum the elements of a set without explicitly using the cycle,.pseudo table level to create pseudo tables t1 and t2 containing numbers from 1 to 16,.This example illustrates a possible workaround using a bypass: SQL does not support cycles, recursions or custom functions. The ‘Hello, World!’ string is selected from the built-in dual table used for queries that do not require access to these tables.

PL/SQL supports program blocks (in the form of functions, procedures and packages that are stored in the database in compiled form and can be executed later, or anonymous blocks that cannot be compiled and are used only with the form of scripts). The third key language used in Oracle DBMS on par with SQL and PL/SQL is Java. The SQL procedural extension developed by Oracle is called PL/SQL (Procedural Language/Structured Query Language) and is based on the syntax of the Ada and Pascal languages.
