SQL: Delete Vs Truncate Vs Drop
 
08:27
In this tutorial, you'll learn the difference between delete/drop and truncate. 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.

CASE Function( IF..THEN..ELSE) in SQL ORACLE Query With Example
 
04:03
ORACLE/PLSQL: CASE STATEMENT The Oracle/PLSQL CASE statement has the functionality of an IF-THEN-ELSE statement. Starting in Oracle 9i, you can use the CASE statement within a SQL statement. The syntax for the Oracle/PLSQL CASE statement is: CASE [ expression ] WHEN condition_1 THEN result_1 WHEN condition_2 THEN result_2 ... WHEN condition_n THEN result_n ELSE result END --------- ARGUMENTS: expression is optional. It is the value that you are comparing to the list of conditions. (ie: condition_1, condition_2, ... condition_n) condition_1 to condition_n must all be the same datatype. Conditions are evaluated in the order listed. Once a condition is found to be true, the CASE statement will return the result and not evaluate the conditions any further. result_1 to result_n must all be the same datatype. This is the value returned once a condition is found to be true. NOTE: If no condition is found to be true, then the CASE statement will return the value in the ELSE clause. If the ELSE clause is omitted and no condition is found to be true, then the CASE statement will return NULL. You can have up to 255 comparisons in a CASE statement. Each WHEN ... THEN clause is considered 2 comparisons. Lets apply this function on emp table. Emp table has 3 dept numbers like 10,20 and 30. So if I want to display the different dept names based on ID, I have to use IF THEN ELSE condition. IF deptno=10 THEN "DEPT1" ELSE deptno=20 THEN "DEPT2" ELSE deptno=30 THEN "DEPT3" This entire IF block can be achived using CASE. CASE deptno WHEN 10 THEN 'DEPT1' WHEN 20 THEN 'DEPT2' WHEN 30 THEN 'DEPT3' ELSE 'NO DEPT' END; Query used in Video: select empno,ename,deptno,CASE deptno WHEN 10 THEN 'DEPT1' WHEN 20 THEN 'DEPT2' WHEN 30 THEN 'DEPT3' ELSE 'No Dept' END from emp;

Welcome to the VIDEO 7 of PL/SQL In these video We will learn about the IF-THEN-ELSIF conditional statement in PL/SQL. Syntax:- IF condition1 THEN statements executed if condition1 is true; ELSIF condition2 THEN statements executed if condition2 is true; . . . ELSIF conditionN THEN statements executed if conditionN is true; ELSE statements executed if all the above condition is false; END IF; 1.Sometimes you want to choose between several alternatives. 2.You can use the keyword ELSIF (not ELSE IF) to introduce additional conditions. 3.If the first condition is FALSE, the ELSIF clause tests another condition. 4.An IF statement can have any number of ELSIF clauses; the final ELSE clause is optional. 5.Conditions are evaluated one by one from top to bottom. 6.If any condition is TRUE, its associated sequence of statements is executed and control passes to the next statement in the pl/sql block. 7.If all conditions are false, the sequence in the ELSE clause is executed. step 1 declare step 2 grade char:='B' grade has a value B step 3 begin step 4 if grade='A' it prints Very Good step 6 if grade='B' it prints Good step 8 if grade='C' it prints Poor step 10 if all the condition is false it prints no such grade as you can see it prints Good because grade='B' is true Please SUBSCRIBE to our Channel Thank you for Watching.

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

The ELSIF clause lets you add additional conditions. When using IF-THEN-ELSIF statements there are few points to keep in mind. It's ELSIF, not ELSEIF An IF-THEN statement can have zero or one ELSE's and it must come after any ELSIF's. An IF-THEN statement can have zero to many ELSIF's and they must come before the ELSE. Once an ELSIF succeeds, none of the remaining ELSIF's or ELSE's will be tested. Subscribe to our Channel for more videos https://www.youtube.com/channel/UC7sbHUgN8FnJEZkEjvKTwJg

DECODE Function ( IF..THEN..ELSE) in SQL ORACLE Query With Example
 
05:35
ORACLE/PLSQL: DECODE FUNCTION The Oracle/PLSQL DECODE function has the functionality of an IF-THEN-ELSE statement. The syntax for the Oracle/PLSQL DECODE function is: DECODE( expression , search , result [, search , result]... [, default] ) ARGUMENTS: expression is the value to compare. search is the value that is compared against expression. result is the value returned, if expression is equal to search. default is optional. If no matches are found, the DECODE function will return default. If default is omitted, then the DECODE function will return null (if no matches are found). Lets apply this function on emp table. Emp table has 3 dept numbers like 10,20 and 30. So if I want to display the different dept names based on ID, I have to use IF THEN ELSE condition. IF deptno=10 THEN "DEPT1" ELSE deptno=20 THEN "DEPT2" ELSE deptno=30 THEN "DEPT3" This entire IF block can be achived using single DECODE(). DECODE(deptno,10,'DEPT1',20,'DEPT2',30,'DEPT3') Query used in Video: select empno,ename,deptno,DECODE(deptno,10,'DEPT1',20,'DEPT2',30,'DEPT3') from emp;

Isn't it great how you "extend" Oracle SQL by calling your own user-defined PL/SQL functions from within SQL statements? Yes, it really is nice, but there are things you need to know about and take into consideration, from read-consistency to optimizer nuances. Chris Saxon gave an overview of the key issues from performance to correctness. Highlights include: 03:30 - performance comparison of plain SQL vs. calling PL/SQL function 04:30 - SQL to PL/SQL context switches; what they are and how they affect performance 06:10 - Techniques to make calling PL/SQL from SQL faster: scalar subquery caching, deterministic keyword, function result cache, pragma UDF 14:00 - Performance comparison of these options 21:20 - Performance comparison when calling non-deterministic functions 35:30 - The danger when you have SQL that calls PL/SQL that calls SQL 41:30 - Calling PL/SQL in SQL dos and don'ts AskTOM Office Hours offers free, monthly training and tips on how to make the most of Oracle Database, from Oracle product managers, developers and evangelists. https://asktom.oracle.com/ Oracle Developers portal: https://developer.oracle.com/ Sign up for an Oracle Cloud trial: https://cloud.oracle.com/en_US/tryit

Best Way to Write Basic SQL Queries
 
13:33
SQL Server Query writing strategies is something I have yet to find in any book. When enthusiastic SQL students do this, they experience a revelation. The number of errors drops significantly and the speed at writing complex queries increases immediately. Knowing how to narrow down what we are looking for amongst a vast list of choices helps immensely. Grabbing the right tables first and then the fields second is akin to grabbing the right menu before ordering an item from it. In fact, one student named Tim took this back to his team of SQL developers and they immediately implemented this process. We are all used to following steps. Most of the time, actions are sequential from top to bottom or left to right. Other times we complete things in phases. The two phases we are going to use in this exercise apply to joining tables. This is easy to implement as we only need remember to organize first and clean up second. When visiting a new restaurant, we will ask to see the menu, because we want to see all they have to offer. The odds are that we might be interested in half of the items, but only need a few dishes for our group at the table. Looking at the menu is like starting a query with a ‘SELECT *’ statement. Once we have looked at all the fields, we narrow our choice(s) to only the items we want at the time. Sometimes restaurants have multiple menus. My favorite restaurant has a kids’ menu, an adult menu, a gluten-free menu and a drink menu. These menus were each gathered at our table. Ultimately, in my head, a selection was narrowed to what was needed. Phase I: Organize. When building a new query from many tables, we often find ourselves wondering, “Where do I start?” First, lay the steps out by identifying which tables contain the essential data. Second, get all the table joins working with a basic ‘SELECT *’ statement. Third, add any basic filtering criteria. Phase II: Itemize. Once all joins and criteria, such as SELECT, FROM and WHERE are working, we are ready for Phase II. This entails going back and changing our ‘SELECT *’ to an itemized SELECT field list as the final step. Let’s explore how this two-phase process of Organize and then Itemize can be a big time-saver. We are going to use one of the challenges from the last lab. In Lab 3.2 (Outer Joins), Skill Check 2, we needed to get four fields from two different tables. If we were to list all four desired fields and test one table at time, we will get an error as seen on the right side of the figure below. In the figure below we write a SELECT statement and part of the FROM clause. When completed, the FROM clause will have two tables, but for now we just want to get the Location table working. By using the ‘SELECT *’ strategy, we remove any possible errors from line 1. From there, we can focus on the more complicated logic used for joining tables together. We can add tables one at a time until everything is working. This is the Organize phase. NOTE: SELECT * never results in an Error message stating “invalid column name”, however; a SELECT list with itemized field(s) can have this error. After our query is organized and working, we can go back and itemize the SELECT field list to display only the fields that are necessary. This is done during Phase II (Itemize). The steps for this system are broken down as follows: Since SELECT is always the first statement in a query, it’s natural to want to write the field names before writing the FROM clause. However; we can save time and trouble by using the ‘*’ until the entire query is working properly. When this is complete, it is very easy to itemize the field list, with the confidence of knowing it will not cause any problems. Exercise: Simple membership for a club: Table1 (id_Member,name_Member, email_member, title, age, company) Table2 (id_Club,club_name, club_Location, address) Table3 (id_club, id_member,membership_date) Q1: Show all member names, email, age, and company from Table1 Q2: Show all club name, location, and address data Q3: Show member name, club name, club location (hint: Use joins and all 3 tables) You can find all other classes related to this video here: http://www.joes2pros.com/joes2pros/Course/Introduction_To_Microsoft_SQL_Server Enroll Today & Get the First Month for only $1!
