R tutorial: connecting to a database
 
03:38
Learn more about connecting to databases with R: https://www.datacamp.com/courses/importing-data-in-r-part-2 Welcome to part two of importing data in R! The previous course dealt with accessing data stored in flat files or excel files. In a professional setting, you'll also encounter data stored in relational databases. In this video, I'll briefly talk about what a relational database is and then I'll explain how you can connect to it. In the next video, I'll explain how you can import data from it! So, what's a relational database? There's no better way to show this than with an example. Take this database, called company. It contains three tables, employees, products and sales. Like a flat file, information is displayed in a table format. The employees table has 5 records and three fields, namely id, name and started_at. The id here serves as a unique key for each row or record. Next, the products table contains the details on four products. We're dealing with data from a telecom company that's selling both with and without a contract. Also here, each product has an identifier. Finally, there's the sales table. It lists what products were sold by who, when and for what price. Notice here that the ids in employee_id and product_id correspond to the ids that you can find in the employees and products table respectively. The third sale for example, was done by the employee with id 6, so Julie. She sold the product with id 9, so the Biz Unlimited contract. These relations make this database very powerful. You only store all necessary information once in nicely separated tables, but can connect the dots between different records to model what's happening. How the data in a relational database is stored and shuffled around when you make adaptations, depends on the so-called database management system, or DBMS you're using. Open-source implementations such as MySQL, postgreSQL and SQLite are very popular, but there are also proprietary implementations such as Oracle Database and Microsoft SQL server. Practically all of these implementations use SQL, or sequel, as the language for querying and maintaining the database. SQL stands for Structured Query Language. Depending on the type of database you want to connect to, you'll have to use different packages. Suppose the company database I introduced before is a MySQL database. This means you'll need the RMySQL package. For postgreSQL you'll need RpostgreSQL, for Oracle, you'll use ROracle and so on. How you interact with the database, so which R functions you use to access and manipulate the database, is specified in another R package called DBI. In more technical terms, DBI is an interface, and RMySQL is the implementation. Let's install the RMySQL package, which automatically installs the DBI package as well. Loading only the DBI package will be enough to get started. The first step is creating a connection to the remote MySQL database. You do this with dbConnect(), as follows. The first argument specifies the driver that you will use to connect to the MySQL database. It sure looks a bit strange, but the MySQL() function from the RMySQL package simply constructs a driver for us that dbConnect can use. Next, you have to specify the database name, where the database is hosted, through which port you want to connect, and finally the credentials to authenticate yourself. This is an actual database that we're hosting, so you can try these commands yourself! The result of the dbConnect call, con, is a DBI connection object. You'll need to pass this object to whatever function you're using to interact with the database. Before we do that, let's get familiar with this connection object in the exercises!

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.

External Table in ORACLE Creating and Loading data from external tables
 
24:30
External Table in ORACLE Creating and Loading data from external tables. To Learn or Teach Linux visit www.theskillpedia.com, A Marketplace for Learners and Trainers. Creating and Loading an External Table Using ORACLE_LOADER The steps in this demonstration show an example of using the ORACLE_LOADER access driver to create and load an external table. A traditional table named emp_list is defined along with an external table named emp_load. The external data is then loaded into an internal table. Step 1. Log in as oracle user and create a Directory to place the data file /u01/app/datafiles: $ mkdir –p /u01/app/datafiles Step 2 Create a file emp_data.dat file with some sample records in /u01/app/datafiles: 45 october, 25, 1968 Sangwan Ram N 09/01/1993 67 december, 25, 1971 Dahiya Sunil D 01/01/1994 Step 3. Execute the following SQL statements to set up a default directory. Notes about this example: • The employee_number field in the datafile is converted to a character string for the employee_number field in the external table. • The datafile contains an employee_dob field that is not loaded into any field in the table. • The substr function is used on the employee_middle_name column in the external table to generate the value for middle_initial in tableemp. • The character string for employee_hire_date in info.dat is automatically converted into a DATE datatype at external table access time, using the format mask specified in the external table definiition. • Unlike employee_hire_date, the DATE datatype conversion for employee_dob is done at SELECT time and is not part of the external table definition.

Read from (SELECT) Database table - SQLite3 with Python 3 part 3

In the previous tutorials, we've covered creating a database and populating one, now we need to learn how to read from the database. Reading from a database is where the power of using something like SQLite over a flat file starts to make sense. While we can query the entire table, we can instead just query a single column, or even based on specific row values.

SQL SERVER PART-12: Oracle Linked Database Server
 
03:46
HOW TO CREATE LINKED SERVER AND HOW TO QUERY ORACLE DATABASE FROM SQL SERVER MANAGEMENT STUDIO. SQL server 2017 makes it easy to configure linked server. You can use open-query to get or manipulate data of linked server database. CONFIGURATION SUMMARY: PROVIDER : oracle provider for oledb. DATA SOURCE : It is usually a combination of oracle server IP: port number/t.n.s listener name. e.g. 192.168.1.10:5121/orcl OPEN QUERY : select * form openquery(linked_server_name, ' sql query statement ') Configure a linked server to enable the SQL Server Database Engine to execute commands against OLE DB data sources outside of the instance of SQL Server. Typically linked servers are configured to enable the Database Engine to execute a Transact-SQL statement that includes tables in another instance of SQL Server, or another database product such as Oracle. Many types OLE DB data sources can be configured as linked servers, including Microsoft Access and Excel. Linked servers offer the following advantages: • The ability to access data from outside of SQL Server. • The ability to issue distributed queries, updates, commands, and transactions on heterogeneous data sources across the enterprise. • The ability to address diverse data sources similarly. An oracle linked server require OLE DB provider. An OLE DB provider is a DLL that manages and interacts with a specific data source. If your oracle database is not in same server then you have to install The Oracle Data Access Components (ODAC) for Windows consists of Oracle client side drivers. An OLE DB data source identifies the specific database that can be accessed through OLE DB. Although data sources queried through linked server definitions are ordinarily databases, OLE DB providers exist for a variety of files and file formats. These include text files, spreadsheet data, and the results of full-text content searches. Typically, linked servers are used to handle distributed queries. When a client application executes a distributed query through a linked server, SQL Server parses the command and sends requests to OLE DB. The row set request may be in the form of executing a query against the provider or opening a base table from the provider.

Connect to the CDB Where Database has to be Plugged in Using the Noncdb Manifest File and Plug the PDDB12C Database. ==- set environment to CDB ==- sqlplus / as sysdba ==- CREATE PLUGGABLE DATABASE NCDB USING 'E:\app\oracle\manifest\NCDB_manifest_file.xml' COPY FILE_NAME_CONVERT = ('E:\APP\ORACLE\ORADATA\NCDB\', 'E:\app\oracle\oradata\CDB1\'); Note: "Below options are supported and you can chose one based on the env" 1) COPY: The datafiles of noncdb remains intact and it is copied to create PDBs at new locations and keep original datafiles intact at the original location. (This would mean that a noncdb database would still be operational after the creation of a PDB). 2) MOVE: The datafiles of noncdb are moved to a new location to create a PDB. In this case, noncdb database would not be available after a PDB is created. NOCOPY: The datafiles of noncdb are used to create a PDB2 and it uses same existing location. In this case, a noncdb database would not be available after a PDB is created. You can use FILE_NAME_CONVERT parameter to specify the new location of the datafiles while using COPY or MOVE option. Step 8. Once Step 7 Completes Successfully, Switch to the PDB Container and Run the "$ORACLE_HOME/rdbms/admin/noncdb_to_pdb.sql". ==- set environment to CDB ==- sqlplus / as sysdba ==- alter session set container=NCDB ==- @$ORACLE_HOME/rdbms/admin/noncdb_to_pdb.sql Step 9. Startup the PDB and Check the Open Mode. ==- set environment to CDB ==- sqlplus / as sysdba ==- ALTER PLUGGABLE DATABASE OPEN; ==-SELECT name, open_mode FROM v$pdbs;

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

Using Oracle to read data from SQL Server
 
10:47
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.

MySQL Workbench Database Export and Import
 
08:08
Learn Database Export and Import using MySQL Workbench. Open MySQL Workbench and logged in to MySQL database server using 'root' username and password. In previous couple of videos we learned how to Create, Alter, Drop Databases and Tables and also how to Insert, Read, Update, Delete data rows using MySQL Workbench. In this lecture we will learn how to Export and Import the database using MySQL Workbench. First of all to Export the databases or tables, from top menu 'Server' select 'Data Export' Option, which opens a new window of data export settings and options. The left section on the window displays all the existing databases on our MySQL database server. When we select a database by clicking on it, it displays all the respected tables under the selected database. We can select one or multiple database check-boxes to include the database in the Export file. Under 'Export Options' section, You can change the default export path of you choice. I'll keep the default one. By selecting first option that is 'Export to Dump Project Folder'. MySQL Workbench will save the save all tables as separate SQL file under one folder. Which is useful when you will be importing or restoring the export file one by one table. I'll go ahead quickly and first save as 'Export to Dump Project Folder', MySQL Workbench displays the progress bar and log. Now, I'll again export the database using 'Export to Self-contained File' option. To demonstrate the import first I'll delete the existing 'students' table under 'mytestdb' database. Display database details by clicking on 'i' symbol, select 'tables' tab. Select and right click 'students' table, and click 'Drop Table' option, confirm and delete the table. Click 'refresh' to update the tables section and we have no table in our 'mytestdb' database. Now select the database and from 'data import' window, select 'import from dump folder. 'Load folder contents' and select only 'mytestdb' database and click start import button to import 'students' table again. Go to 'mytestdb' database information window again and click 'refresh' button to reload table list again. and the 'students' table is back.
