OBIEE Dynamic Session Variables - Creating and Using in an Analysis - OBIEE Online Training
 
12:33
This video tutorial demonstrates how to create an OBIEE database-driven session variable using the BI Admin Tool. The initialization block selects data from a database table to set the value of the variable. After creating the session variable and init block, we can then use the variable in an analysis filter, and well as display the value in the title view.- https://www.fireboxtraining.com/obiee-training

Connection Pool with an Oracle Database - DBArch  Video 19
 
08:06
In this video you will learn the concept of a Connection pool an application uses with a Database. You will learn the need for connection pool and how it helps in optimizing resource utilzation on the Database Server. You will learn that Logon and Logoff are the most resource intensive tasks in a database, and hence both tasks should be avoided during normal operations of the application and database.

BluePrism - Environment & Session Variables || Reality & Useful
 
35:23
Hi Friends, Let's come into the development/implementation part. Environment variables We have two types of environment variables, mean we can declare process level and business level in System Manager. See here, You saw this, I created one environment variable in Business level but I can see under process also. Then why the tool differentiated under process and business object? It's a categorizing the variables that's it. we will access the created environment variable in process Here is my process, let's access the varible into internal data item. I Created the local data item. to access the environment variable configure the local data item. We have the Expose option in data item, open it and see 'Environment - Read the corresponding Environment variable from System Manager' But I didn't find my 'hello' variable. Let's close and reopen it. See I got it and select the env variable name from the list. But how can I see value for that environment variable. Let's do it. 1. I created another local variable and using calculation stage copying the value from configured data item to local variable. Can we edit the environment variable value? Try that once. See, before executing the bot while reset, I am getting error message open and see that what is the message 'Cannot store data in an environment variable' even If you run it won't work. See that I got the internal exception. Environment variables are final variables, once you declare the varible only you can change the value in System Manager and cannot be possible through process/Business Object. ----------------------------------------------------------------------------------- Let's create/open another process or business object and see can we able to access the same environment variable or not? See I got the environment variable and it's value in newly created process. ------------------------------------------------------------------------------------ Now we will see about Session Varible. let's revert the code of existing process as I will concatenate the environment variable value to local variable and storing the result into local variable. Let's run and check it. I got the concatenated value. If we run through control room can we see these value? Let's publish our process and run it from control room. process started and finished. Where we can see the session variables. There is a link to see session variables 'Show Session Variables' I enabled, let's run and check it Started and finished, but we cannot see the data item value. Because we didn't configured the data item to show in session variables list. For this, we need to expose the local data item to show in session variables list. Open the process and open the data item and choose the option called 'Session - Expose the data item to Control Room' Now run and check it once We did the right way to show the data item in session variables list but why can't we see the variable value? To that the process/business object show wait for some to before complete it. Because our process is very small. let's use the wait stage before end Ohh! We don't have wait stage in process, how use the sleep Action in General Business Object. drag the Action stage and choose the values. I choosen the 'Utility - General' and Sleep and passed the how many seconds should wait our process let's run and see it See that while the process is in running mode we can see the configured session variable. After finished the process it's gone. Thank you for watching video

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.

Structured Query Language(SQL) as we all know is the database language by the use of which we can perform certain operations on the existing database and also we can use this language to create a database. SQL uses certain commands like Create, Drop, Insert etc. to carry out the required tasks. These SQL commands are mainly categorized into four categories as discussed below: 1. DDL(Data Definition Language) : DDL or Data Definition Language actually consists of the SQL commands that can be used to define the database schema. It simply deals with descriptions of the database schema and is used to create and modify the structure of database objects in database. Examples of DDL commands:  CREATE – is used to create the database or its objects (like table, index, function, views, store procedure and triggers).  DROP – is used to delete objects from the database.  ALTER-is used to alter the structure of the database.  TRUNCATE–is used to remove all records from a table, including all spaces allocated for the records are removed.  COMMENT –is used to add comments to the data dictionary.  RENAME –is used to rename an object existing in the database. 2. DML(Data Manipulation Language) : The SQL commands that deals with the manipulation of data present in database belong to DML or Data Manipulation Language and this includes most of the SQL statements. Examples of DML:  SELECT – is used to retrieve data from the a database.  INSERT – is used to insert data into a table.  UPDATE – is used to update existing data within a table.  DELETE – is used to delete records from a database table. 3. DCL(Data Control Language) : DCL includes commands such as GRANT and REVOKE which mainly deals with the rights, permissions and other controls of the database system. Examples of DCL commands:  GRANT-gives user’s access privileges to database.  REVOKE-withdraw user’s access privileges given by using the GRANT command. 4. TCL(transaction Control Language) : TCL commands deals with the transaction within the database. Examples of TCL commands:  COMMIT– commits a Transaction.  ROLLBACK– rollbacks a transaction in case of any error occurs.  SAVEPOINT–sets a savepoint within a transaction.  SET TRANSACTION–specify characteristics for the transaction.
