Oracle SQL Tutorial 32 - VARCHAR2 and NVARCHAR2
 
03:06
This video we are going to discuss the VARCHAR2 and the NVARCHAR2 data types. The previous videos are a good foundation to this video. I've actually discussed so much stuff in those videos that I don’t have a whole lot to say. Good for you, right? I discussed over the previous videos that you should prefer to use VARCHAR2 over CHAR. That's because there is not a difference in performance or storage for a VARCHAR2 column. The only difference is that an CHAR column forces each value to take up a certain length even if it's not. There is one difference between the variable length and fixed length data types here that you need to know about, and that is storage limits. CHAR has a limit of 2000 bytes, while VARCHAR2 has a limit of 4000 bytes. That means you can store twice as much junk in a VARCHAR2 column! Other than that, these data types work exactly the same. I recommend you always use the VARCHAR2 data types instead of the CHAR data types, and only use NVARCHAR2 if you have a non-Unicode database. This will allow you to store Unicode characters in a column. Now, the amount of storage you can put in a VARCHAR2 column is twice what you can put in a CHAR column, but 4000 characters is still not very many characters. This is where the LOB data types come in, which we will discuss in the next video! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle EMPTY_BLOB Function
 
01:58
https://www.databasestar.com/oracle-lob-functions/ The Oracle EMPTY_BLOB function is used to initialise a LOB column to an empty value. You can use it in an INSERT statement, an UPDATE statement, or with a variable in PL/SQL. The syntax of the EMPTY_BLOB function is: EMPTY_BLOB That’s it - no parameters. Why would you set a BLOB value to empty? It means you have initialised it but not given it a value. It’s good to know this function exists if you ever need to use it. For more information about the Oracle EMPTY_BLOB function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-lob-functions/

What's Inside Oracle Data Block?
 
19:53
Join the biggest Oracle community online: https://dbagenesis.com/ Oracle manages the storage space in the datafiles of a database in units called data blocks. A data block is the smallest unit of data used by a database. In contrast, at the physical, operating system level, all data is stored in bytes. Each operating system has a block size. Oracle requests data in multiples of Oracle data blocks, not operating system blocks.

Full Transportable Export/Import into the DBaaS Cloud - Oracle 12c
 
20:54
Video provided by Roy Swonger - Database Upgrade and Utilities Product Manager and Senior Director at Oracle Corporation Video lenght: 20 minutes This video demonstrates first of all how to use the Oracle Database 12c feature "Full Transportable Export/Import". This feature utilized Transportable Tablespaces as a cross-version and cross-platform migration technology but let Oracle Data Pump handle all the manual stuff involved with TTS and xTTS in just one command. Furthermore the feature can be combined with RMAN Incremental Backups to decrease the downtime if necessary and desired. Please find a presentation at the Database Upgrade Blog at: https://blogs.oracle.com/UPGRADE/ in the Slides Download Center titled: Full Transportable Export/Import with RMAN Incrementals In addition Roy is demonstrating also how to utilize this feature to migrate a database into the Oracle DBaaS Cloud. Interesting fact: Even though Full Transportable Export is an Oracle Database 12c feature included in the standard license set it can be used with an Oracle 11.2.0.3 or Oracle 11.2.0.4 database - but the destination version must be at least an Oracle Database 12.1.0.1 (or newer). Further question? Please get in touch with us via the Oracle Database Upgrade Blog: https://blogs.oracle.com/UPGRADE/ Thanks!

How to create Virtual Columns in Oracle Database
 
09:02
How to create Virtual Columns in Oracle Database 12c When queried, virtual columns appear to be normal table columns, but their values are derived rather than being stored on disc. The syntax for defining a virtual column is listed below. column_name [datatype] [GENERATED ALWAYS] AS (expression) [VIRTUAL] If the datatype is omitted, it is determined based on the result of the expression. The GENERATED ALWAYS and VIRTUAL keywords are provided for clarity only. The script below creates and populates an employees table with two levels of commission. It includes two virtual columns to display the commission-based salary. The first uses the most abbreviated syntax while the second uses the most verbose form. CREATE TABLE employees ( id NUMBER, first_name VARCHAR2(10), last_name VARCHAR2(10), salary NUMBER(9,2), comm1 NUMBER(3), comm2 NUMBER(3), salary1 AS (ROUND(salary*(1+comm1/100),2)), salary2 NUMBER GENERATED ALWAYS AS (ROUND(salary*(1+comm2/100),2)) VIRTUAL, CONSTRAINT employees_pk PRIMARY KEY (id) ); INSERT INTO employees (id, first_name, last_name, salary, comm1, comm2) VALUES (1, 'JOHN', 'DOE', 100, 5, 10); INSERT INTO employees (id, first_name, last_name, salary, comm1, comm2) VALUES (2, 'JAYNE', 'DOE', 200, 10, 20); COMMIT; Querying the table shows the inserted data plus the derived commission-based salaries. SELECT * FROM employees; ID FIRST_NAME LAST_NAME SALARY COMM1 COMM2 SALARY1 SALARY2 ---------- ---------- ---------- ---------- ---------- ---------- ---------- ---------- 1 JOHN DOE 100 5 10 105 110 2 JAYNE DOE 200 10 20 220 240 2 rows selected. SQL The expression used to generate the virtual column is listed in the DATA_DEFAULT column of the [DBA|ALL|USER]_TAB_COLUMNS views. COLUMN data_default FORMAT A50 SELECT column_name, data_default FROM user_tab_columns WHERE table_name = 'EMPLOYEES'; COLUMN_NAME DATA_DEFAULT ------------------------------ -------------------------------------------------- ID FIRST_NAME LAST_NAME SALARY COMM1 COMM2 SALARY1 ROUND("SALARY"*(1+"COMM1"/100),2) SALARY2 ROUND("SALARY"*(1+"COMM2"/100),2) 8 rows selected. SQL Notes and restrictions on virtual columns include: 1)Indexes defined against virtual columns are equivalent to function-based indexes. 2)Virtual columns can be referenced in the WHERE clause of updates and deletes, but they cannot be manipulated by DML. 3)Tables containing virtual columns can still be eligible for result caching. 4)Functions in expressions must be deterministic at the time of table creation, but can subsequently be recompiled and made non-deterministic without invalidating the virtual column. In such cases the following steps must be taken after the function is recompiled: a)Constraint on the virtual column must be disabled and re-enabled. b)Indexes on the virtual column must be rebuilt. c)Materialized views that access the virtual column must be fully refreshed. d)The result cache must be flushed if cached queries have accessed the virtual column. e)Table statistics must be regathered. 5)Virtual columns are not supported for index-organized, external, object, cluster, or temporary tables. 6)The expression used in the virtual column definition has the following restrictions: a.It cannot refer to another virtual column by name. b.It can only refer to columns defined in the same table. c.If it refers to a deterministic user-defined function, it cannot be used as a partitioning key column. e.The output of the expression must be a scalar value. It cannot return an Oracle supplied datatype, a user-defined type, or LOB or LONG RAW.

PL/SQL: Object Type
 
08:31
In this tutorial, you'll learn what is a object type in sql/plsql 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.

PLS-4: PL/SQL Variables

View & manage your progress/pace 3. In-class projects and code reviews 4. Personal guidance from your Mentors ---------------------------------------------------------------------------------------- A variable is nothing but a name given to a storage area that our programs can manipulate. Each variable in PL/SQL has a specific data type, which determines the size and layout of the variable's memory; the range of values that can be stored within that memory and the set of operations that can be applied to the variable. The name of a PL/SQL variable consists of a letter optionally followed by more letters, numerals, dollar signs, underscores, and number signs and should not exceed 30 characters. By default, variable names are not case-sensitive. You cannot use a reserved PL/SQL keyword as a variable name. PL/SQL programming language allows to define various types of variables, which we will cover in subsequent chapters like date time data types, records, collections, etc. For this chapter, let us study only basic variable types. With PL/SQL you can declare variables and then use them in SQL and procedural statements anywhere that an expression can be used. Variables can be used for the following: • Temporary storage of data: Data can be temporarily stored in one or more variables for use when validating data input and for processing later in the data flow process. • Manipulation of stored values: Variables can be used for calculations and other data manipulations without accessing the database. • Reusability: After they are declared, variables can be used repeatedly in an application simply by referencing them in other statements, including other declarative statements. • Ease of maintenance: When using %TYPE and %ROWTYPE (more information on %ROWTYPE is covered in a subsequent lesson), you declare variables, basing the declarations on the definitions of database columns. If an underlying definition changes, the variable declaration changes accordingly at run time. This provides data independence, reduces maintenance costs, and allows programs to adapt as the database changes to meet new business needs. More information on %TYPE is covered later in this lesson. Types of Variables" All PL/SQL variables have a data type, which specifies a storage format, constraints, and valid range of values. PL/SQL supports four data type categories—scalar, composite, reference, and LOB (large object)—that you can use for declaring variables, constants, and pointers. • Scalar data types hold a single value. The main data types are those that correspond to column types in Oracle server tables; PL/SQL also supports Boolean variables. • Composite data types, such as records, allow groups of fields to be defined and manipulated in PL/SQL blocks. • Reference data types hold values, called pointers, that designate other program items. Reference data types are not covered in this course. • LOB data types hold values, called locators, that specify the location of large objects (such as graphic images) that are stored out of line. LOB data types are discussed in detail later in this course.
