This is a very common sql server interview question. Object explorer with in sql server management studio can be used to get the list of tables in a specific database. However, if we have to write a query to achieve the same, there are 3 system views that we can use. 1. SYSOBJECTS - Supported in SQL Server version 2000, 2005 & 2008 2. SYS.TABLES - Supported in SQL Server version 2005 & 2008 3. INFORMATION_SCHEMA.TABLES - Supported in SQL Server version 2005 & 2008 -- Gets the list of tables only Select * from SYSOBJECTS where XTYPE='U' -- Gets the list of tables only Select * from SYS.TABLES -- Gets the list of tables and views select * from INFORMATION_SCHEMA.TABLES To get the list of different object types (XTYPE) in a database Select Distinct XTYPE from SYSOBJECTS Executing the above query on my SAMPLE database returned the following values for XTYPE column from SYSOBJECTS IT - Internal table P - Stored procedure PK - PRIMARY KEY constraint S - System table SQ - Service queue U - User table V - View Please check the following MSDN link for all possible XTYPE column values and what they represent. http://msdn.microsoft.com/en-us/library/ms177596.aspx

In this video ,we will generate the script that will return us all the table names with column names and data type of those columns. We often need this information. Let's say we are going to prepare mapping document for load the data from Source Database to Destination database. We can get the list of all tables with column names and data types from Source Database and Destination Database and then paste in Excel and map the required input columns to output columns for ETL Process.

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

08 of  13 - Oracle APEX 5 - List of values (LOV) for a field in a form; display a hidden column
 
13:22
A new series using APEX 18.1 is now available. https://youtu.be/vgrkiIpJEiQ This is one in a series of videos about creating an application using Oracle APEX 5. In this video we create two lists of values (LOVs) in the Shared Components section of our application. We use each LOV in place of a field in a form. We see how APEX will help us write the SQL for a LOV. The difference between a "display value"and a "return value"is discussed. Finally, we display the primary key field in a form, which APEX hides by default. See the primary key field in a form can be helpful during application development.

21:25
A new series for APEX 18.1 is available. https://youtu.be/vXkNH3ktdaI This is one in a series of videos about creating an application using Oracle APEX 5. In this video we create a view that uses one-sided outer joins to show ALL records from one table and any related records from other tables. We use a full outer join to to show ALL records in both tables. (By default, when you join 2 tables you only see records that are related between the two tables.) Next, we modify the main navigation menu. Last, we make some pages public so no login is required to view these pages. SQL scripts for this series are available to download at: http://db.kreie.net

SELECT * FROM Students WHERE Name LIKE 'M%' We can use any one of the following 3 SQL Server functions, to achieve exactly the same thing. CHARINDEX LEFT SUBSTRING The following 3 queries retrieve all student rows whose Name starts with letter 'M'. Notice none of the queries are using the LIKE operator. SELECT * FROM Students WHERE CHARINDEX('M',Name) = 1 SELECT * FROM Students WHERE LEFT(Name, 1) = 'M' SELECT * FROM Students WHERE SUBSTRING(Name, 1, 1) = 'M'

There are many ways to get data into DataTables. If the data is small you can retrieve all the data at once and the processing (i.e paging, searching, ordering) is done on the client-side. On the other hand if the database data is large, server-side processing can be enabled. With server-side processing enabled, all paging, searching, ordering actions that DataTables performs are handed off to the server. In this video we will discuss retrieving all the data at once. The datatables plugin performs all the processing (i.e paging, searching, ordering etc) on the client-side. We want to retrieve data from the following database table tblEmployee. The database data should then be displayed using jQuery datatables plugin

The view then renders the data. Model can be entities or business objects. In part 7, we have built Employee entity. public class Employee { public int EmployeeId { get; set; } public string Name { get; set; } public string Gender { get; set; } public string City { get; set; } } In this video, we will discuss, retrieving data from a database table tblEmployee using entity framework. In a later video, we will discuss using business objects as our model. Step 1: Install entity framework, if you don't have it installed already on your computer. At the time of this recording the latest version is 5.0.0.0. Using nuget package manager, is the easiest way to install. A reference to EntityFramework.dll is automatically added. Open visual studio - Tools - Library Package Manager - Manage NuGet Packages for Solution Step 2: Add EmployeeContext.cs class file to the Models folder. Add the following "using" declaration. using System.Data.Entity; Copy & paste the following code in EmployeeContext.cs public class EmployeeContext : DbContext { // Replace square brackets, with angular brackets public DbSet[Employee] Employees {get; set;} } EmployeeContext class derives from DbContext class, and is responsible for establishing a connection to the database. So the next step, is to include connection string in web.config file. Step 3: Add a connection string, to the web.config file, in the root directory. Step 4: Map "Employee" model class to the database table, tblEmployee using "Table" attribute as shown below. [Table("tblEmployee")] public class Employee { public int EmployeeId { get; set; } public string Name { get; set; } public string Gender { get; set; } public string City { get; set; } } Note: "Table" attribute is present in "System.ComponentModel.DataAnnotations.Schema" namespace. Step 5: Make the changes to "Details()" action method in "EmployeeController" as shown below. public ActionResult Details(int id) { EmployeeContext employeeContext = new EmployeeContext(); Employee employee = employeeContext.Employees.Single(x =] x.EmployeeId == id); return View(employee); } Step 6: Finally, copy and paste the following code in Application_Start() function, in Global.asax file. Database class is present "in System.Data.Entity" namespace. Existing databases do not need, database initializer so it can be turned off. Database.SetInitializer[MVCDemo.Models.EmployeeContext](null); That's it, run the application and notice that the relevant employee details are displayed as expected.

This new video checks that and makes sure it automatically redirects any request to the login page when it finds out that the user isn't logged in. - - - - - - - - - - - - - - - - - - - C O U R S E S - - - - - - - - - - - - - - - - - - - { B O O T C A M P S } - - The Web Developer Bootcamp: http://bit.ly/2NpDcKR - - The Complete Web Developer in 2018: Zero to Mastery: http://bit.ly/2N0ZW4F { P H P } - - PHP for Beginners - Become a PHP Master - CMS Project: http://bit.ly/2u5QMIw - - Create a REAL Social Network like Facebook in PHP + MySQL: http://bit.ly/2wUv3om - - PHP with Laravel for beginners - Become a Master in Laravel: http://bit.ly/2QcbeRf - - PHP OOP - Understand Object Oriented Programming in PHP: http://bit.ly/2CysNs3 { P Y T H O N } - - Complete Python Bootcamp: Go from zero to hero in Python 3: http://bit.ly/2wSybRs - - Complete Python Masterclass: http://bit.ly/2oNWfQW { J A V A S C R I P T } - - Modern JavaScript From The Beginning: http://bit.ly/2wUHdwD - - The Complete JavaScript Course 2018: Build Real Projects!: http://bit.ly/2wUlZ1L - - Modern React with Redux: http://bit.ly/2QcWBx0 - - MERN Stack Front To Back: Full Stack React, Redux & Node.js: http://bit.ly/2CAaeDY

Part 6   Transform rows into columns in sql server
 
08:53
Link for all dot net and sql server video tutorial playlists http://www.youtube.com/user/kudvenkat/playlists Link for slides, code samples and text version of the video http://csharp-video-tutorials.blogspot.com/2014/06/part-6-transform-rows-into-columns-in.html This is another common sql server interview question. We will be using Countries table in this example. SQL to create the table Create Table Countries ( Country nvarchar(50), City nvarchar(50) ) GO Insert into Countries values ('USA','New York') Insert into Countries values ('USA','Houston') Insert into Countries values ('USA','Dallas') Insert into Countries values ('India','Hyderabad') Insert into Countries values ('India','Bangalore') Insert into Countries values ('India','New Delhi') Insert into Countries values ('UK','London') Insert into Countries values ('UK','Birmingham') Insert into Countries values ('UK','Manchester') Here is the interview question. Write a sql query to transpose rows to columns. Using PIVOT operator we can very easily transform rows to columns. Select Country, City1, City2, City3 From ( Select Country, City, 'City'+ cast(row_number() over(partition by Country order by Country) as varchar(10)) ColumnSequence from Countries ) Temp pivot ( max(City) for ColumnSequence in (City1, City2, City3) ) Piv

Dynamic SQL in Stored Procedure
 
09:32
In this video we will discuss, using dynamic sql in a stored procedure and it's implications from sql injection perspective. We will discuss performance implications of using dynamic sql in a stored procedure in a later video. Text version of the video http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-in-stored-procedure.html Slides http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-in-stored-procedure_11.html All SQL Server Text Articles http://csharp-video-tutorials.blogspot.com/p/free-sql-server-video-tutorials-for.html All SQL Server Slides http://csharp-video-tutorials.blogspot.com/p/sql-server.html All SQL Server Tutorial Videos https://www.youtube.com/playlist?list=PL08903FB7ACA1C2FB All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists Consider the following stored procedure "spSearchEmployees". We implemented this procedure in Part 139 of SQL Server tutorial. This stored procedure does not have any dynamic sql in it. It is all static sql and is immune to sql injection. Create Procedure spSearchEmployees @FirstName nvarchar(100) = NULL, @LastName nvarchar(100) = NULL, @Gender nvarchar(50) = NULL, @Salary int = NULL As Begin Select * from Employees where (FirstName = @FirstName OR @FirstName IS NULL) AND (LastName = @LastName OR @LastName IS NULL) AND (Gender = @Gender OR @Gender IS NULL) AND (Salary = @Salary OR @Salary IS NULL) End Go Whether you are creating your dynamic sql queries in a client application like ASP.NET web application or in a stored procedure, you should never ever concatenate user input values. Instead you should be using parameters. Notice in the following example, we are creating dynamic sql queries by concatenating parameter values, instead of using parameterized queries. This stored procedure is prone to SQL injection. Let's prove this by creating a "Search Page" that calls this procedure. Create Procedure spSearchEmployeesBadDynamicSQL @FirstName nvarchar(100) = NULL, @LastName nvarchar(100) = NULL, @Gender nvarchar(50) = NULL, @Salary int = NULL As Begin Declare @sql nvarchar(max) Set @sql = 'Select * from Employees where 1 = 1' if(@FirstName is not null) Set @sql = @sql + ' and FirstName=''' + @FirstName + '''' if(@LastName is not null) Set @sql = @sql + ' and LastName=''' + @LastName + '''' if(@Gender is not null) Set @sql = @sql + ' and Gender=''' + @Gender + '''' if(@Salary is not null) Set @sql = @sql + ' and Salary=''' + @Salary + '''' Execute sp_executesql @sql End Go Add a Web Page to the project that we have been working with in our previous video. Name it "DynamicSQLInStoredProcedure.aspx". Copy and paste the HTML and code available on my blog at the following link http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-in-stored-procedure.html At this point, run the application and type the following text in the "Firsname" text and click "Search" button. Notice "SalesDB" database is dropped. Our application is prone to SQL injection as we have implemented dynamic sql in our stored procedure by concatenating strings instead of using parameters. ' Drop database SalesDB -- In the following stored procedure we have implemented dynamic sql by using parameters, so this is not prone to sql injecttion. This is an example for good dynamic sql implementation. Create Procedure spSearchEmployeesGoodDynamicSQL @FirstName nvarchar(100) = NULL, @LastName nvarchar(100) = NULL, @Gender nvarchar(50) = NULL, @Salary int = NULL As Begin Declare @sql nvarchar(max) Declare @sqlParams nvarchar(max) Set @sql = 'Select * from Employees where 1 = 1' if(@FirstName is not null) Set @sql = @sql + ' and [email protected]' if(@LastName is not null) Set @sql = @sql + ' and [email protected]' if(@Gender is not null) Set @sql = @sql + ' and [email protected]' if(@Salary is not null) Set @sql = @sql + ' and [email protected]' Execute sp_executesql @sql, N'@FN nvarchar(50), @LN nvarchar(50), @Gen nvarchar(50), @sal int', @[email protected], @[email protected], @[email protected], @[email protected] End Go On the code-behind page, use stored procedure spSearchEmployeesGoodDynamicSQL instead of spSearchEmployeesBadDynamicSQL. We do not have to change any other code. At this point run the application one more time and type the following text in the "Firstname" textbox and click the "Search" button. ' Drop database SalesDB -- Notice "SalesDB" database is not dropped, So in this case our application is not succeptible to SQL injection attack. Summary : Whether you are creating dynamic sql in a client application (like a web application) or in a stored procedure always use parameters instead of concatnating strings. Using parameters to create dynamic sql statements prevents sql injection.

CAPTIONS AVAILABLE - I assume that it's the "I like!" votes that keep this video at or near the top when you search on "oracle". Thank you to all. S. Faroult View on www.konagora.com where Youtube is blocked. Full transcript (with some screenshots) available for a small fee at http://stores.lulu.com/konagora/. A pretty reckless description of what happens when you start Oracle and when you execute a statement. If you're a developer, it could influence how you code. If you're a junior DBA, or would be junior DBA, I hope it will help you make sense of some parts of the "Concepts" manual.

Part 7   Using stored procedures with entity framework

Step 1: Create and populate Employee table. Step 2: Create Insert, Update and Delete stored procedures Step 3: Create a new empty asp.net web application Step 4: Add a new ADO.NET Entity Data Model. a) On Choose Model Contents screen select "Generate from database" option and click Next b) On "Choose Your Data Connections" screen give a meaningful name for the connection string that will be stored in the web.config file. I have named it EmployeeDBContext. Click Next. c) On "Choose Your Database Objects" screen, select Employees Table and the 3 strored procedures (InsertEmployee, UpdateEmployee, DeleteEmployee). Provide a meaningful name for the Model namespace. I have named it EmployeeModel. CLick Finish. At this point on the ADO.NET Entity Model designer surface, we should be able to see the Employee entity but not the stored procedures. To view the stored procedures, 1. Right click on entity model designer surface and select "Model Broswer" from the context menu. 2. Expand Stored Procedures folder Step 5: Add a webform to the project. Drag and drop the following 3 controls and build the solution. 1. GridView 2. DetailsView 3. EntityDataSource Step 6: Configure EntityDataSource control a). Right click on EntityDataSource control and select "Show Smart Tag" option b) Click on Configure Data Source link c) Select EmployeeDBContext from the Named Connection dropdownlist and click Next d) Select the options on "Configure Data Selection" screen as shown in the video Step 7: Configure GridView control a). Right click on GridView control and select "Show Smart Tag" option b) Click on "Auto Format" link and select "Colourful" scheme c) Select "EntityDataSource1" from "Choose Data Source" dropdownlist d) Select Enable Editing and Enable Deleting checkboxes Step 8: Configure DetailsView control a) Right click on DetailsView control and select "Show Smart Tag" option b) Click on "Auto Format" link and select "Colourful" scheme c) Select "EntityDataSource1" from "Choose Data Source" dropdownlist d) Select Enable Inserting checkbox e) Set DeafultMode=Insert. Use properties window to set this. f) Set InsertVisible="false" for the ID BoundField. You can do this directly in the HTML Source. g) Generate ItemInserted event handler method for DetailsView control. Copy and paste the following code. protected void DetailsView1_ItemInserted(object sender, DetailsViewInsertedEventArgs e) { GridView1.DataBind(); } At this point if you run the application, and if you insert, update and delete employees, by default entity framework will use the sql it autogenerates and not our custom stored procedures. To tell the entity framework to use the stored procedures, we have to map them to the Employee entity. Here are the steps. 1. Right click on "Employee" entity on "EmployeeModel.edmx" and select "Stored Procedure Mapping" option from the context menu. 2. In the "Mapping Details" windows specify the Insert, Update and Delete stored procedures that you want to use with "Employee" entity At this point, 1. Run SQL Prrofiler 2. Run the application 3. Insert, Update and Delete Employee, and notice that the respective stored procedures are being called now.
