SQL with Oracle 10g XE - Using ALTER TABLE to Modify Table Columns
 
05:23
In this video I use the ALTER TABLE command to modify an existing field column. The command will allow you to change the data types, whether the field can be null, or even the primary key. When using the ALTER TABLE command you would use the keyword MODIFY to make changes to an existing column. Be careful when changing a data type of the null field as existing data may cause an error if not in compliance with the new change. The code I used to alter the Books table is : ALTER TABLE BOOKS MODIFY ISBN_10 VARCHAR(13); This video is part of a series of videos with the purpose of learning the SQL language.

SQLPLUS: LineSize & PageSize
 
03:49
In this tutorial, you'll learn how to set linesize and pagesize . 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.

We can also say that SQL tables are kind of data structure which are used by database for efficient storage of data. To create a table in our database we use SQL CREATE TABLE command. SQL CREATE TABLE is a type of DATA DEFINITION LANGUAGE also known as DDL. To Create a table in your schema you will require CREATE TABLE system privilege. In our future videos we will see what are system and object privileges and how to grant them to a user. Today for this video we will be using Sample schema HR which already has all the necessary privileges. Ohk Let's see the syntax. CREATE TABLE table name ( column name1 Data-Type(size), column name2 Data-Type(size), ..... ); CREATE TABLE is an oracle reserved word or say an Oracle key word whereas There are 3 different ways of creating a table in Oracle database. Creating a table using Command Line Interface (CLI) in Oracle database For demonstrating how to create table in oracle database using CLI, I'll be using Command prompt. Thats how we create table using command prompt. you can check your table structure by DESCRIBE command for that just write DESC and your table name. Like this Another way of creating a table is by using Graphic user interface (GUI) in Oracle database To demonstrate how to create table using GUI we will use SQL developer. Lets open our SQL developer I am connected to HR schema if you do not know how to create a connection to database using SQL developer please watch my oracle database tutorial 4 that explains database connectivity using SQL developer and command prompt. Link for this video is in the description below. So lets create a table. Creating a table using SQL developer is very easy we do not have to fire any query here. Let's start First of all right click on your connection in which you want to create a table and choose schema browser. This will open a separate schema browser pane or you can expend your connection by clicking this + sign and then right click on table and choose New Table. However I prefer working with schema browser so let's skip to schema browser pane here from the first drop-down list you can choose connection name and in the second drop down list you can choose what database objects you want to work with we want to create a table thus I'll choose table and then click this arrow here and choose option for new table Ok we have created a table wizard first of all give a unique name to your table and add some column as well. For this, click the green plus button. Now we already have a column so give it some name. Also choose a datatype from the list and specify any size you can check this not null column if in case you want to make this a mandatory column you can also specify default value and constraint If you want to make this column a primary key you can click here In my future video i'll show you what are these constraints and different ways of applying them on a column in a table. for this video we will concentrate on create table only so when you are done with all your columns click ok Thats your table You can double click on your table here and can see its structure. Thats it

A Story of Indexes and Full Table Scans: Finding All the Red Sweets Part 1
 
08:43
"Why isn't Oracle using my index?!" is a common question people have when tuning SQL queries. In this episode Chris compares two methods for finding all the red candies from party bags he's prepared. He shows how these are like a full table scan and an index range scan. He goes on to compare the performance of these two approaches. He shows when a full table scan becomes more efficient than an index range scan and vice versa. ============================ The Magic of SQL with Chris Saxon Copyright © 2015 Oracle and/or its affiliates.

Oracle SQL Tutorial 33 - NUMBER Data Type
 
07:18
This video we are going to discuss the NUMBER data type. The Number data type is used to store integers, and real numbers. When you create a column as a NUMBER, you can store pretty huge or pretty small numbers in this column. Now there are two things you need to consider when working with numbers, and that is the precision as well as the how big the number is. For example, we can store the number 9.9. This has two significant digits. We could also store the number 9.9 X 10^4. In this situation, the number is much larger, but the number of significant digits is the same. 9.9 are the significant digits. When we expand this out we just have 99000, and the zeros are just used for size and are not considered "significant" in this situation. In fact, you get a max precision of 38, but a maximum value of 9.99 * 10^125. You can also use this data type to store very small numbers. Check the docs for the specifics on maximums and minimums. You can provide it with two pieces of information: Precision - The total number of digits. Scale - The number of digits to the right of the decimal. You do it in this format: NUMBER (precision, scale). The important thing to remember in this is that when you specify a precision, you will be limiting the max size of the numbers. The secret behind this data type is that it is actually stored in scientific notation. That is we store a number and then we can multiply it by 10 raised to some power. This allows us to store much larger numbers without taking up a ton of space. The oracle docs actually gives a formula that you can use to see how much storage is going to be required for a specific NUMBER data type. How much precision can be used? The acceptable range is 1-38. What about scale? The range is actually -84 to 127. I'll explain the scale in more detail in an upcoming video. That's because there is a lot of confusing things here…What does it mean for the scale to be negative? How can we have a scale that is bigger that the total number of digits available through the precision. That's a topic for another video. It's important to understand that when we increase our scale, we decrease the max size of the number. For example if we have a precision of 5 and a scale of 3, the highest number we can store is 99.999. This is in contrast to a precision of 5 and a scale of 2 which allows for up to 99.999. Either way you get 5 significant digits, but the numbers of digits to the left and right of the decimal change. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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 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!)

The numbers are same for Latin characters but they are different for Unicode and other encodings. How to represent ENUMs and SETs internally? A:ENUMs and SETs are used to represent powers of two because of storage optimizations. What is the usage of ENUMs in MySQL? A:ENUM is a string object used to specify set of predefined values and that can be used during table creation. Define REGEXP? A:REGEXP is a pattern match in which matches pattern anywhere in the search value. Difference between CHAR and VARCHAR?

Importing Data from Excel into Oracle Database using SQL Developer 4.1
 
02:23
One of SQL Developer’s most popular features has undergone a significant upgrade. Users can quickly define and recall delimited or Excel files to be imported to a new or existing Oracle table. Data preview and validation is provided for each column, as well as ‘best guess’ data type and date format mask mapping. This process can now be automated via the SQL Developer command line interface (SDCLI) ‘Import’ command. NOTE: This is a video only. There is no audio. Copyright © 2015 Oracle and/or its affiliates.

Oracle Tuning Tutorial - Long Full Table Scans Part 2 of 5
 
06:33
See all 5 tutorials, free, at SkillBuilders.com/OracleTuningFullTableScans Number Eight in the "Performance tuning Guide, Top Ten Mistakes Found in Oracle Systems" Long Full Table Scans is described as follows: "Long full table scans for high-volume or interactive online operations could indicate poor transaction design, missing indexes, or poor SQL optimization. Long table scans, by nature, are I/O intensive and unscalable." Actually, there are many cases where the full table scan is your friend. But whether they are good or bad for the performance of the SQL that invokes them, there may be implications (for better or for worse) for performance of other statements. This is particularly true in 11.2.x, where direct reads are possible for serial scans, and indirect reads are possible for parallel scans. Do you trust the optimizer? The change in behaviour in recent releases may need some investigation, and revisiting older code. As always with a SkillBuilders Tutorial, we shall illustrate the issues and solutions with live demonstrations using release 11g (11.2.0.3). Audience: Operating System Administrators, Storage Administrators, Oracle Administrators and Management responsible for Storage and / or Oracle Databases.

Every VARCHAR2(N) Declaration a Bug in PL/SQL!?
 
07:51
Every VARCHAR2(N) Declaration a Bug!? That's right. VARCHAR2 declarations mean that you have to provide an "N" or constraint on the size of the variable. If you have such declarations all over your code, that's a form of hard-coding and you are likely to get hammered by VALUE_ERROR exceptions. This video shows how to fix this problem.

Working with the Trace File Analyzer Collector
 
28:22
The Trace File Analyzer (TFA) Collector Tool is a utility for collecting first failure diagnostics when creating Service Requests with Oracle Support. Using TFA Collector to make diagnostic collections removes questions about what files to collect and upload. TFA knows about all the well known Oracle and operating system diagnostic locations and collects only files that have been modified proximate to problem time specified from any of those well known locations. Larger files are also pruned proximate to problem time specified to reduce the size of the upload. If the system is a clustered environment TFA collects relevant diagnostics from the remote nodes as well. All of this can be accomplished with one simple command. Key features of TFA Collector include: RAC and single instance non-RAC support Time-based collection of relevant files OS Clusterware ASM DB OSW and CHMOS etc Large file pruning Cluster-wide time-relevant collections Analytics for key files DB alert logs Clusterware alert logs ASM alert logs system messages OSWatcher top and slabinfo data Flexible command-line interface Copyright © 2014 Oracle and/or its affiliates.

MySQL 27 - TEXT, TINYTEXT, MEDIUMTEXT, LONGTEXT
 
03:42
The TEXT data types have not yet been discussed, but they are another string data type. They are similar to the VARCHAR data type with some minor differences that are important to know. The first thing to note is that there are four versions used to determine different sizes. From least to greatest size is TINYTEXT, TEXT, MEDIUMTEXT, LARGETEXT. These each have different maximum byte sizes: 255, 65535, 16 million something, and 4 billion something. You create a column as one of these data types just as you would with a varchar column. You work with them exactly the same, too. If that is the case, what are the primary differences between these and VARCHAR? The first difference is that VARCHAR is restricted by the row limit of a table. TEXT tables do not contribute nearly as much (max of 12 bytes) because the data is not stored inline in the table. This means that if you need to allow for extra space for other rows, you can use a TEXT column. And even though the table only contains a pointer to the data, it is all hidden to us and working with a TEXT column is the same as working with a VARCHAR column. The second primary difference is that TEXT data types do not allow for a default other than NULL. Thirdly, VARCHAR is limited to just under 64KB, whereas you can use MEDIUMTEXT or LARGETEXT to allow for more storage. So if what you are trying to store as an individual value is over 64KB, use a text column. Other than those three things, VARCHAR will usually work just fine for our text needs. Now, last thing is that these data types are often called CLOB data types. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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!)

This video explains basic SAP OpenSQL by reading records from a table in the SAP database, storing those records in an internal table and then displaying the contents. I'm using data declarations for internal tables and type-definitions as well as the newer (ver 7.4 and above) inline declarations. The code. Please note that the angle bracket (>) is not allowed in YouTube video descriptions. If you intend to copy this code then please substitute the > for the smaller keyboard version. There are four programs here.

How will you eliminate duplicate values from a query result in MySQL?
 
02:45
Q. How will you eliminate duplicate values from a query result in MySQL? MySQL provides DISTINCT keyword to remove duplicates from a query result. With DISTINCT keyword, a value will be displayed only once. Eg. SELECT DISTINCT NAME FROM EMPLOYEE; This query will return each name in Employee table only once. Q. How will you get the size of data in a MySQL table? In MySQL, there is an information_schema that contains the TABLES object. We can run a query on TABLES to get the size of data in a table. Eg. If we have a table named EMPLOYEE, the query to get the size of data will be as follows: SELECT table_name "Table Name",sum( data_length + index_length ) / 1024 / 1024 "Table Size (MB)" FROM information_schema.TABLES WHERE table_name='EMPLOYEE'; Learn more MySQL interview questions, join our popular MySQL Interview Questions Preparation Course with more than 50 questions for $10 only today!! https://www.udemy.com/mysql-interview-questions-preparation-course/?couponCode=KPOWER10 Source: http://www.knowledgepowerhouse.com/video-course
