Steps to create a cursor in sql

When you write a multilingual or multi-cultural application in .NET, and want to distribute the core application separately from the localized modules, the localized assemblies that modify the core application are called satellite assemblies.

Steps to Create Satellite Assembly
a. Set the paths for resgen and al.exe:
b. Create a .resources file.
c. Create the satellite assembly.
d. The assembly should have the naming convention for .NET to be able to search for it.
e. Specify the settings for culture.
f. Put the satellite assembly in the appropriate folder.
g. Once the satellite assembly is created, physically copy it to the appropriate directory.
h. Repeat the process for each language in which you are creating an assembly.

When a class declares only private instance constructors, it is not possible for classes outside the program to derive from the class or to directly create instances of it. (Except Nested classes)
Make a constructor private if:

1) You want it to be available only to the class itself. For example, you might have a special constructor used only in the implementation of your class' Clone method.

2) You do not want instances of your component to be created. For example, you may have a class containing nothing but Shared utility functions, and no instance data. Creating instances of the class would waste memory. (More...)

CREATE TABLE .. AS SELECT command

Explanation :

To copy only the structure, the WHERE clause of the SELECT command should contain a FALSE statement as in the following.
CREATE TABLE NEWTABLE AS SELECT * FROM EXISTINGTABLE WHERE 1=2;
If the WHERE condition is true, then all the rows or rows satisfying the condition will be copied to the new table. (More...)

Cursor is a database object used by applications to manipulate data in a set on a row-by-row basis, instead of the typical SQL commands that operate on all the rows in the set at one time.
In order to work with a cursor we need to perform some steps in the following order:
. Declare cursor
. Open cursor
. Fetch row from the cursor
. Process fetched row
. Close cursor
. Deallocate cursor

Cursor plays there row quite nicely but although there are some disadvantage of Cursor .Because cursor doing roundtrip it will make network line busy and also make time consuming methods. First of all select query gernate output and after that cursor goes one by one so roundtrip happen.


Another disadvange of cursor are ther are too costly because they require lot of resources and temporary storage so network is quite busy. (More...)

A cursor is used to access the result set stored in the memory on execution of a query. It is a special programming construct that allows data to be manipulated on a row-by-row basis. They point to a certain location within a record set and allow the operator to move forward (and sometimes backward, depending upon the cursor type) through the results one record at a time (More...)
