What will you do if you need to create clustered index on more than one field? Is it possible?

Posted By :shah268     Posted Date :November 26, 2009    Points :10   Category :Sql Server 
The answer is yes and no.
You can create clustered index only one clustered index in table.
Either you can create index on entire table or you can create clustered index on a view covering entire table.
Suppose, you have created table with following:
CREATE TABLE [dbo].[Table1](
[field1] [int] IDENTITY(1,1) NOT NULL,
[field2] [nchar](10) ,
[field3] [nchar](10) ,
[field4] [nchar](10)
) ON [PRIMARY]
Create index on entire table:
CREATE INDEX idx_coverTable ON Table1(field1, field2) INCLUDE (field3, field4)
Create clustered index on a view covering entire table:
CREATE VIEW v1111 with SCHEMABINDING
AS
SELECT field1, field2, field3, field4 FROM dbo.Table1
GO
CREATE UNIQUE CLUSTERED INDEX idx_viewClustered ON dbo.v1111(field1, field2, field3, field4)
GO

Is it possible to create Cluster Index on Unique Key Column?

  
Unique key column by default creates a non-cluster index on the column. Primary key creates cluster index on the column. The only difference is Unique key column allows only one null value. So is it possible to have cluster index on Unique key column?

The answer is YES. Though Unique key allows null value but it still maintains the uniqueness of the column. (More...)

What is the basic difference between clustered and a non-clustered index

  
The difference is that, Clustered index is unique for any given table and we can have only one clustered index on a table. The leaf level of a clustered index is the actual data and the data is resorted in case of clustered index. Whereas in case of non-clustered index the leaf level is actually a pointer to the data in rows so we can have as many non-clustered indexes as we can on the db. (More...)

how many clustered and non-clustered index can a table have

  
In SQL 2005 and earlier there was a limitation of 250 indexes per table, one clustered and 249 non-clustered. In SqL 2008, with the addition of filtered indexes, that limitation was increased to 1000, one clustered and 999 non-clustered indexes. (More...)

What's the difference between a clustered and a non-clustered index

  
clustered index directly affects the way tabled data is stored on a specific disk. This means that when a clustered index is used, data is stored in sequential rows based on the index column value. This is why a table can only contain a single clustered index. Non-clustered indexes directly affect the way physical data is stored and managed within SQL Server. (More...)

What is Private Constructor? and it's use? Can you create instance of a class which has Private Constructor?

  
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...)

What is a Index?

  
To execute the Quesry faster (More...)

What are the requirements to create a CLR based user-defined type?

  
CLR must be enabled for the instance and A class created with a CLR-compatible language. (More...)
