     Oracle supports 4 types of tables based on how data is organized in storage:

     Ordinary (heap-organized) table

     •A basic, general purpose table •Data is stored as an unordered collection (heap)

     Clustered table

     •A part of a cluster •Cluster: A cluster is a group of tables that share the same data blocks as they share common columns and are often used together.

     Index-organized table

     •Data is stored in a B-tree index structure in a primary key sorted manner. •Each index entry in the B-tree stores the non-key column values as well.

     Partitioned table

     •Data is broken down into smaller, more manageable pieces called partitions or sub-partitions. •Each partition can be managed individually •Each partition can operate independently

     IMO you should use this

     SELECT a, b, c, CASE WHEN NOT ((a+b>c) AND (a+c>b) AND (b+c>a)) THEN 'Not A Triangle' WHEN a = b AND b = c THEN 'Equilateral' WHEN a = b OR b = c OR c = a THEN 'Isosceles' ELSE 'Scalene' END AS resultFROM table_name;

     Tested in rextester

     If you use output parameters, marked with the "out" keyword, you must pass a variable for that parameter. Output params are not optional. From the error, I gather that you have not done so.

   • Types of SQL Injection (SQLi)

     SQL Injection is an attack that employs malicious SQL code to manipulate backend databases in order to obtain information that was not intended to be shown, The data may include sensitive corporate data, user lists, or confidential consumer details. This article contains types of SQL Injection with their examples. SQL Injections-LABS (a platform to learn SQL Injections) to showcase how you can perform each type of SQL Injections.

      

     1. Error-Based SQL Injections:

     Error-based SQL Injections obtain information about the database structure from error messages issued by the database server. In rare circumstances, an attacker may enumerate an entire database using only error-based SQL injection.

     Example:

     In SQL Injections labs, if you type ?id=1 in the URL and press enter, it gives you the login name and password.

     But if we type ?id=1’ it gives an error.

   • Dividing SQL Into Sublanguages. Structured Query Language, or SQL, is a comprehensive language for manipulating databases. It is the language used in database systems such as PostgreSQL, MySQL, Microsoft SQL Server, and Oracle Database.
   • Data Query Language (DQL) The Data Query Language, or DQL for short, is the group of commands responsible for querying data from a database. The principal DQL command in SQL is the SELECT command, which retrieves data from one or more tables.
   • Data Manipulation Language (DML) The Data Manipulation Language, or DML for short, is the group of commands responsible for manipulating data in a database; this generally entails inserting, editing, or deleting rows in SQL tables.
   • Data Definition Language (DDL) The Data Definition Language, or DDL, is made up of the commands responsible for creating, editing and deleting SQL tables.
