SQLSERVER 4: Creating Tables in SQL Server

The basic building block of storing data in SQL Server Database is a “Table” aka “Relation”. It’s a collection of rows and columns grouped together.

Ø Rows in a table are aka Tuples, Records.

Ø Columns in a table are aka Fields, Attributes, Columns.

The following figure clearly explains the terminology:

We can see that the above figure represents a Relation / Table named “DEPT” and it has got fields like “Deptno”, “Dname” etc.

The following command is used to create a table:

Create Table Dept

(

Deptno numeric(10),

Dname varchar(100),

Loc varchar(100)

)

We are creating a table with 3 columns. And two columns have “varchar” datatype and Deptno has got “numeric” datatype. DataType means what kind of Data we can store in that field. Numeric as name suggests can store numbers and Varchar can store alphanumeric.

We will have more on DataTypes in the coming posts for different data types in SQL Server.

So we have created our first table in SQL Server.

Stay tuned for more.!!!

How to use QueryExtenderControl in ASP.NET with LINQ

Queryextender control is a control that helps in doing actions like filtration, searching, sorting etc. on the LINQ Data source with few steps. In fact we don’t have to write any code with this. Screenshot given below is just an example that can easily be achieved through this control. In the above screenshot, we can see that there is a GridView Control that has been binded to a LINQData Source Control. And we have a DropDownlistBox that is also binded to another LINQData Source Control and displaying only grouped jobs. The GridView display all the employees who are matching the Job Parameter. This is done through QueryExtender Control. Also we can search for any name in the employee name's through Query Extender control. The code in the HTML goes like: < form id ="form1" runat ="server"> < div > Select Job: < asp : DropDownList ID ="Job" runat ="server" DataSourceID ="LinqDataSource2...

Using GUID or UniqueIdentifiers in SQL Server

In order to differentiate between two rows, we normally use primary keys or identity values which may be same across two tables. In order to overcome this problem we can use a special type named "GUID" . Its a hexadecimal number (Base 16) and the advantage is that they are unique across all databases and tables. In SQL Server the same concept is implemented through UNIQUEIDENTIFIER data type. In order to generate a new value, we use the NEWID() function. For e.g. a. Creating a table that uses the UNIQUEIDENTIFIER datatype Create table Test ( Empno uniqueidentifier, Ename varchar(20) ) b. Inserting rows in the tables with the use of NEWID() function insert into Test values (newId(),'ABC') insert into Test values (newid(),'XYZ') insert into test values (newid(),'MNO') c. Selecting the rows from the table. Select * from test Empno ...

How to Delete Record through Knex.

This post is all about of deleting records through KNEX ORM in Nodejs. The following code shows how to achieve this: knex("depts").where("deptno","50").del() .then(function (count) { console.log(count); }) .finally(function () { knex.destroy(); }); The above code deletes a record from a table "Depts" where Deptno = 50. It has a "then" Promise attached that will show how many records were deleted with this command. Also "finally" is the method that will always execute and will close the KNEX connection. Happy Coding !!!
