COL11: Set-Level Manipulation of Nested Tables (MULTISET)
 
22:23
Oracle offers set-level operators and functions to manipulate nested tables. You can perform unions and intersects, check nested tables for equality and more. This lessons explores the MULTISET features of nested tables in detail.

Oracle CAST Function
 
03:23
https://www.databasestar.com/oracle-cast/ The Oracle CAST function allows you to convert one data type to another. It’s similar to the TO_NUMBER, TO_DATE, and TO_CHAR functions, but allows for more functionality, including converting to many other data types. The syntax of the CAST function is: CAST( {expr | MULTISET (subquery) } AS type_name ) The structure of this function is different to other functions, because it uses the word AS to separate parameters rather than a comma. You can run this function like many other functions, on a single row, which would look like this: CAST( expr AS type_name ) Or, you can run it as though it’s a subquery, using the MULTISET feature: CAST( MULTISET (subquery) AS type_name ) The parameters of the CAST function are: - expr (mandatory choice): This is the value or expression that is to be converted to another data type. - MULTISET (optional): This keyword indicates that the subquery results will return multiple rows, and are then CAST into a collection value. If this is omitted, and the subquery returns multiple rows, it will only return a single row. - subquery (mandatory choice): This is the subquery that can be run to be converted into a collection data type. - type_name (mandatory): This is the Oracle data type that the expr or subquery will be converted to. There are several data types that are compatible with the CAST function, both for converting from and to. You can find the full list in the article mentioned below. For more information about the Oracle CAST function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-cast/

Dates in Oracle PL SQL is definitely the most powerful among all other databases. It gives us full flexibility to manipulate it of our choice, whether you are calculating days, months or year, printing date and time in various format. Useful date functions add_months, months_between, last_day, next_day and to_char helps us a lot in handling date time in our pl sql programming.

Top Nine Coding Guidelines for Oracle PL/SQL
 
08:00
My take, as of November 2015, of some of the most helpful guidelines to follow when writing PL/SQL code: 1. MAXSQL - maximize use of SQL first and foremost 2. SPOD - single point of definition 3. TRACE - production-available application-level tracing 4. LOG - consistent, encapsulated error logging 5. BULK - avoid row by row 6. OBVIOUS - make your code tell its own story, comment when it can't 7. NESTPROG - use nested subprograms 8. DECLARE - use declarative features of language 9. WARN - use compile-time warnings Accompanying blog post: http://stevenfeuersteinonplsql.blogspot.com/2015/10/your-ideas-for-more-important-plsql.html ======================================== Practically Perfect PL/SQL with Steven Feuerstein Copyright © 2015 Oracle and/or its affiliates.

PL/SQL: Brief on Nested tables
 
04:00
In this tutorial, you'll learns the points to be noted on Nested tables PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.
