How to : Selecting oracle long or long raw using odp.net in c#
 
02:34
Selecting oracle long or long raw using odp.net in c# Selecting data using the Oracle Data Provider for .NET (ODP.NET) is quite simple, however, if you forget a simple step, you may end up selecting blank fields for your LONG or LONG RAW's. As usual, you'll need the proper using clause (or else your code will be overly verbose): using Oracle.DataAccess.Client;using System.Data; Then in your code, simply do: string connstr = "PutYourConnectionStringHere"; OracleConnection conn = new OracleConnection(connstr); OracleCommand cmd = new OracleCommand("SELECT * FROM MYTABLE", connstr); // next line says to fetch first 1000 characters of LONG or LONG RAW fields.  If you omitted this, it would bring back blank fields instead. cmd.InitialLONGFetchSize = 1000; DataSet ds = new DataSet(); OracleDataAdapter da = new OracleDataAdapter(cmd); // use the data adapter to fill the dataset da.fill(ds); // now if any results came back, ds.Tables[0] will have your data. At this point, you should be able to use the data, as you would any other datasource.

Oracle SQL Tutorial 1 - Intro to Oracle Database
 
10:18
As illustrated in the video, Oracle Database is a program designed to hold lots of information, or data. There are all kinds of different databases and they all have their uses. Some of the most common ones are MySQL, SQL Server, Sybase, and MongoDB. All of these have different uses. The differences will be easier to understand after you learn more about each kind of database. We did not discuss it much in the video, but if you are wondering what “SQL” means in the title, it stands for structured query language. Structured query language is a human readable computer language that is used to tell databases to do things. We will discuss SQL and Oracle SQL Developer more in future videos. Databases are better than spreadsheets because they allow multiple users at one time, different levels of access given to users, recovery options and transactions, and it is more protected from hacking and malicious destruction. Programming languages often have very useful functions or methods that can be used to communicate to a database and therefore they are a naturally good option for the back end of programs. This course will go over all of the major parts of database programming using Oracle SQL. We will be using Oracle 11g, but these videos should still work with other versions, including the most recent 12c. Q and A ~~~~~~ How much does Oracle cost? The full enterprise edition costs thousands. They have other versions for less and they even have a FREE VERSION! This is known as the XE version (eXpress Edition). That is the one we will be using. How long does it take to learn SQL? You can learn all of the basics and be an efficient beginner database developer in only about a month of practice. To become an intermediate it can take anywhere from an additional 3 - 6 months with a only a few hours of studying and practicing each day. How can I learn SQL faster? Take notes and actually mess around with making your own database. Watch these videos until you understand the concepts within them, read articles and books that teach in more depth.

Oracle NVL2 Function
 
03:05
https://www.databasestar.com/oracle-nvl-nvl2-logical-functions/ The Oracle NVL2 function is an extension of the NVL function and can be used to handle NULL values. It allows you to specify a value to check for NULL, a separate value to return if the value is NULL, and another value to return if the first value is not NULL. It’s very similar to NVL but allows for more flexibility. The syntax for NVL2 is: NVL2( value_to_check, value_if_not_null, value_if_null ) What are these parameters: Value_to_check is the value the function checks to see if it is NULL. Value_if_not_null is the value to return if the first value, value_to_check, is not NULL. Value_if_null is the value to return if the first value, value_to_check, is NULL. These parameters can have almost any data type (the second and third parameter can’t be a LONG data type). Oracle will determine the data type from the supplied parameters. There are quite a few of these conditional checking functions in Oracle, so the one to use would depend on your needs. But it’s good to know this function exists. For more information about the Oracle NVL2 function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-nvl-nvl2-logical-functions/

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!

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.

Welcome back to another tutorial on Java JDBC. In this video we're going to learn how to read and write BLOBs. For this tutorial we're going to use the employees table. I have a SQL script that will create the table and add sample data for you. You can download it from the link below. The file is sql/table-setup.sql. Time - 00:28 So what exactly is a BLOB? Well a BLOB is basically binary data that we store in the database. You normally use BLOBs to keep track of documents, images, audio, or any other binary object that you have. Note that not all databases have support for BLOBs. In this example we’re going to make use of MySQL and they have BLOB support. Time - 00:48 On this slide we will learn how to create a BLOB column. So when we create a table in MySQL we add a column with the BLOB data type. On this slide I want to learn how to write a BLOB to a database. For this example I'm going to add a resume for an employee. I'm going to read a local PDF file and I'll take that file and update the database with the binary data that's the actual content of PDF file. Let's walk through the code. Time - 01:17 At the beginning I’ll set up a SQL statement. I’ll say update employees set resume equals to question mark where the email address equals [email protected] We’re only going to make a change for this John Doe employee, set up a prepared statement, and then I go, we’re going to create a file that's an actual handle to the local file sample_resume.pdf. Then I’ll set, on my statement I’ll set the binary stream, that first parameter for the resume comma the input. That's the input stream I have for that file. Then I actually call my statement .executeUpdate. That will actually update the database with the binary data. Time - 01:54 All right so let's switch over to Eclipse and let’s look at a very simple demo. I have a program called WriteBlobDemo. In this program we're going to actually read a resume from a local file system and write it as a BLOB to the database. I’ll walk through the code here. The first thing we do is we get a connection to the database. We prepare a statement. We're going to update employees, set resume equals to question mark where email equals [email protected] So we’re going to update the resume for John Doe. Time - 02:22 Then I’ll move down, I’ll set up a file handle for this file sample_resume.pdf. I’ll set up an input stream on that file and then I’ll set that as the parameter for our binary stream for our prepared statement. Then I’ll move through and I’ll actually do an execute update. This will actually store this binary file from the file system into the actual database column. Time - 02:47 I just ran the application and here's the output of the program. So beginning it says that it’s reading the file and gives me the full path to the file just for sanity sake, I know which file is actually reading. Then it tells me that it's storing the resume in the database for our employee [email protected] and then it says that it completed successfully. Excellent. Time - 03:10 Now let's move over to MySQL tool and verify this. I'll take a look at the employees there in the database right now. l’ll run this query select * from employees and I'll get a list of the actual employees. Notice here for John Doe there’s an entry here for a resume, there's a BLOB entry. Note all the other entries are null. So we have a BLOB entry here. I can select this entry. I can right click. I can say, “Open Value in Editor” and it’s going to show me this BLOB. Again, it's a binary large object so we see all this binary data. Actually it should be displayed as hex. Time - 03:50 Instead of looking at it in this fashion there's a tab here called “Image.” I can select this tab and now it'll actually show me this image or the actual data as a PDF that I can view. This is the actual PDF document for this employee, John Doe. This looks really good. We know that we were successful in storing the BLOB in the actual database. Time - 04:18 Now that we know how to write BLOBs in the database let's learn how to read a BLOB from the database. In this example I'm going to read the employee’s resume from the database as a BLOB and then store it as a file on my local files system. Let's walk through the code.

The game is set in Ancient Greece, and will feature RPG elements, including dialogue options and the ability to select between a male or female protagonist. The player takes control of a Spartan rejected by their family, making the journey from outcast mercenary to legendary hero, learning the truth about their past along the way. Both Alexios and Kassandra start the game as a mercenary and a descendant of the Spartan king Leonidas I. They inherit his broken spear, which is forged into a blade to become a weapon that grants the player special abilities in combat. The game uses a skill tree system that allows the player to unlock new abilities. The three skill trees include "hunter", which improves player character's archery, "warrior" which puts emphasis on combat, and "assassin" which focuses on stealth. This replaces the system used in Origins, which granted the player a series of passive abilities.
