How to create and use database link in Oracle
Database link are used to connect to database which is on different host and different instance, where you cannot use schema.table_name. But it gives you the freedom to manipulate the remote database table as if they are located in you own schema. This is the first part of database link video, on next videos will show you how database link can be used in datawarehousing.

Using Oracle to read data from SQL Server
Hi everyone, Andy from Easysoft Limited here, what I want to show you today is how to get data from SQL Server into Oracle. Now for this we will be accessing SQL Server 2014 from Oracle 12 and getting data across. This could be quite easily be any SQL Server version from 2008 and any Oracle version from 11.2, the configuration and process is the same. We can obviously get access to data on SQL Server prior to 2008 and Oracle prior to version 11.2 but it will need a different configuration to what I am going to show you today The plan is also to add more data to the SQL Server table and show this new data back in Oracle. To start off you'll need access to ensure that you have access to your SQL Server and Oracle databases. You'll also need the Easysoft SQL Server ODBC Driver available from www.easysoft.com; just download it, install it and request the free 14 day trial licence. Before we start we need to make some changes to the standard Easysoft config files. cat /etc/odbc.ini Here I have changed Mars Connection to Yes. It must be set to "Yes" if you are connecting to SQL Server 2005 or newer. Easysoft supports all SQL data types from the version of SQL Server from version 7. Oracle supports data types that are common to most ODBC Drivers, but not some of the SQL Server ones. If you intend to access VARCHAR(MAX) for example, then there are some additional settings that need to be set up. Now as I would like to show you VARCHAR(MAX) data moving from SQL Server to Oracle, I have made the relevant change. As you can see, VarMaxAsLong says "Yes" We now need to create a link from Oracles Database Gateway (DG4ODBC) to the ODBC datasource that we already have, this is done in an init(sid) oracle file; let's have a look at our file. cat $ORACLE_HOME/hs/admin/initsqlsrv.ora Please note that HS_NLS_NCHAR must be set to UCS2 Oracle assume that most database vendors use UTF-8 for wide characters, however Easysoft, like almost all ODBC Driver vendors (including Oracles own ODBC Driver) uses UCS2 for wide characters. So that's the link between DG4ODBC and the datasource setup correctly. Next we need to set up the Listener entry The Oracle Listener waits for incoming requests from the Oracle database. For the Oracle Listener to listen for requests, information about DG4ODBC must be added to the Oracle Listener configuration file, listener.ora cat $ORACLE_HOME/network/admin/listener.ora The PROGRAM=dg4odbc tells the Listener that we are wanting to use the Oracle database gateway to communicate with ODBC. The ENVS=LD_LIBRARY_PATH tells Oracle what library to load Now that's all set up and OK we need to tell Oracle which server to attach the listener entry to. This is done in tnsnames.ora, and he is the file that we ensured was set up earlier. cat $ORACLE_HOME/network/admin/tnsnames.ora The Oracle Listener now needs to be restarted. lsnrctl stop lsnrctl start OK, that's now started the Listener up again. So we have ensured that all the configuration files are set up correctly. The Listener and tnsnames.ora both set up OK. The final step is to create a link from the Oracle database to the "tnsnames.ora" entry. CREATE PUBLIC DATABASE LINK ODBC CONNECT TO "test" IDENTIFIED BY "test" USING 'sqlsrv_ptr'; Right, that's all done. Let's access the data in SQL Server now. select * from [email protected]; Where 'demo' is the name of the SQL Server table and 'odbc' is the public database link name. OK, there we have the data. So to recap, I'm in Oracle and we have managed to read the data from SQL Server. Let's just add an additional row in that SQL Server table and retrieve the new data in Oracle. quit; /usr/local/easysoft/unixODBC/bin/isql.sh -v sqlsrv insert into demo values (2,'Easysoft') select * from demo select * from [email protected]; And there is the new data. Easysoft Limited can help you with your data access ... for our full range of ODBC and JDBC Drivers, Bridges and Gateways visit easysoft.com Be sure to let us know if you have any comments or questions. Until next time, thanks again and we'll see you again soon.

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

SQLAlchemy: Connecting to a database
Learn how to connect to your database: https://www.datacamp.com/courses/introduction-to-relational-databases-in-python In the python world, there are several great tools that we can use when working with databases. One of those is SQLAlchemy that we will be using throughout this course. SQLAlchemy will allow us to generate SQL queries by writing Python code. You should still consider learning how to write queries in SQL as well. SQLAlchemy has two main components. The part we will be focusing on is often referred to as "core" part of SQLAlchemy. It's really focused around the relational model of the database. Additionally, there is the Object Relational Model or ORM part of SQLAlchemy that is really focused around data models and classes that you as a programmer create. There are many different types of databases, and each database type has its own quirks and unique capabilities. You'll commonly find SQLite, PostgreSQL, MySQL, Microsoft SQL Server, and Oracle when working with data. SQLAlchemy provides a way to operate across all of these database types in a consistent manner. To connect to a database, we need a way to talk to it, and an engine provides that common interface. To create an engine, we import the create_engine function from sqlalchemy; we then use the create_engine function and supply it a connection string that provides the details needed to connect to a database. Finally once we have an engine, we are ready to make a connection using the connect method on the engine. It's worth noting that SQLAlchemy won't actually make the connection until we give it some work to execute. So to review, an engine is the common interface to the database, which requires a connection string to provide the details used to find and connect to the database. Before we go any further, let's talk a bit more about connection strings. In their simplest form, they tell us what kind of database we are talking to and how we should access it. In this example, you can see that we are using the sqlite database driver and the database file named census_nyc.sqlite which is in the current directory. Now that we have an engine and a connection, we need to know what tables are in the database. We'll start again by importing the create_engine function and creating an engine to our database. Finally, We can use the table_names method of the engine which returns a list of tables. Once we know what table we want to work on, we need a way to access that table with python. To do that we are going to use a handy process called reflection, which reads the database and builds a Table object that we can use in our code. We already have created our engine, so we begin by importing the MetaData and Table objects needed for reflection. The MetaData object is a catalog that stores database information such as tables so we don't have to keep looking them up. To reflect the table, we initialize a MetaData object. Next, we use the SQLAlchemy Table object and provide the table name we got earlier from the table_names method. We also supply our metadata instance, and then instruct it to autoload the table using the engine. Finally, we can use the function repr to view the details of our table that we stored as census. This allows us to see the names of the columns, such as 'state' and 'sex', along with their types, such as VARCHAR and INTEGER. This process of reflection may seem a bit of an overhead, but it will make understanding your databases and extracting information from them far easier downstream. Now it's your turn to practice writing connection strings, connecting to databases and reflecting tables. Then we'll be back here writing our first SQL queries.

If not, you can download one from the site listed here on the slide. Time - 00:20 Next, we’ll need to download and install a MySQL JDBC driver. This driver will allow the Java program to connect to the database. You can download it from this URL, and I’ll do that now. I’ll just take this URL, drop it into my favorite browser and here I am at the page. I’m on this page, this is for downloading the Connector/J browser. I’ll select the platform, platform independent. Now move down and I’ll select download and it will download a zip archive. Make sure you download the most recent version. In this case it’s 5.1.29. Make sure you download something at that version or later. Time - 01:04 Download, scroll down, select, “No thanks, just start my download.” This will start downloading the file for you. Now what we can do is show it in the finder. I’ll double click it to extract it. At this point I have the driver extracted. There’s a file in here called MySQL connector.jar that we’ll use later. Time - 01:34 Next, what I need to do is create a Java project in Eclipse. Let’s do that. On Eclipse I’ll say I’ll save file, new, Java project. This will be JDBC demo and I will select finish. What I’ll do is I will add a new class. New, class, this will be my driver and it will have a public static void main region. At this point we have a shell for our project created. Time - 02:28 Next, what we’ll do is we will talk to the actual development process and I really like this slide because it outlines exactly what we need to do. The first thing we’ll do is add the database driver to the classpath. Next, we’ll get a connection, we’ll submit a SQL query and then we’ll process the result set. Time - 02:48 Let’s start with step one, adding a MySQL database driver to the classpath. In our Eclipse project I’m going to add a new folder called lib, lib for library. In this lib folder I’m going to add the driver that I downloaded earlier. What I’ll do is I’ll just grab this driver. It’s the MySQL connector bin.jar and I’ll just drag and drop it to this lib folder. It will prompt me and I’ll say go ahead and copy the file. Time - 03:25 Next, I need to add the jar file, the driver to the classpath. I’ve set this up with properties, choose Java build path and then I’ll choose add jars. Expand this folder, that lib, I’ll grab that jar file and I’ll have it setup. Great. Time - 03:51 Now we can start coding. We need to get a connection, submit a SQL query and process a result set. Let me just sketch this out on a slide over here. The first thing I’ll do up top is I’ll just do an import on java.sql.* because all of the classes and interfaces that we need are in this package. Time - 04:17 I’ll also just setup a try catch block just to handle for any exception that may occur. Small typo there. Time - 04:40 Inside of this section I’m going to first get a connection to database. Then next I will create a statement. Then from here I will execute a SQL query and then I will process the result set. Time - 05:16 That’s my basic game plan, let’s fill it in with some real code. Here I’ll say connection, myConn = DriverManager.getConnection. I’ll give the jdbc:mysql://localhost:3306/demo student, student. Student is the user ID and student is also the password.
