What are the conditions under which a function can be schema bound?

What are the conditions under which a function can be schema bound?

A function can be schema bound only if the following conditions are true:
  • The function is a Transact-SQL function.
  • The user-defined functions and the views it references are also schema-bound.
  • The objects that the function references are referenced using a two-part name.
  • The function and the objects it references belong to the same database.
  • The user who executed the CREATE FUNCTION statement has REFERENCES permission on the database objects that the function references.
  • SCHEMABINDING cannot be specified for functions that reference alias data types or CLR functions.

Attitude



An old man lived alone in a village.

He wanted to spade his potato garden, but it was very hard work.

His only son, who would have helped him, was in prison.

The old man wrote a letter to his son and mentioned his situation:

Dear Son,

I am feeling pretty bad because it looks like I won't be able to plant my potato garden this year.

I hate to miss doing the garden, because your mother always loved planting time.

I'm just getting too old to be digging up a garden plot.

If you were here, all my troubles would be over.

I know you would dig the plot for me, if you weren't in prison.

Love,

Dad

Shortly the old man received this telegram:

"For Heaven's sake, Dad, don't dig up the garden!! That's where I buried the GUNS!!"

At 4 a.m the next morning, a dozen FBI agents and local police officers showed up and dug up the entire garden without finding any guns.

Confused, the old man wrote another note to his son telling him what happened, and asked him what to do next.

His son's reply was:

"Go ahead and plant your potatoes, Dad.. It's the best I could do for you from here."


Moral:
"NO MATTER WHERE YOU ARE IN THE WORLD,
IF YOU HAVE DECIDED TO DO SOMETHING DEEP FROM YOUR HEART YOU CAN DO IT. IT IS THE THOUGHT THAT MATTERS.. NOT WHERE YOU ARE OR WHERE THE PERSON IS"

Install multiple versions of IE on your PC


















Install multiple versions of IE on your PC

Ever wanted to test your website in various versions of Internet Explorer?

Every time you install a newer version of Internet Explorer, Windows has a tendency to overwrite previous versions. And generally, that's a good thing. You're missing out on an awful lot if you're using Internet Explorer 3 to browse the web these days. AJAX, Flash, and other newfangled features just aren't going to work as well, or at all.

But if you're a developer and you want to see how your website looks to someone running an ancient browser, you might want to install an old copy of Internet Explorer alongside your IE7. And it turns out that this is completely doable if a little complicated. You need to alter some settings, redirect some DLLs, and rename a few things here and there.

If you have a PC running Windows XP (it doesn't work for Vista) and you want to test your application in multiple versions of Internet Explorer, you need to install this software.

XML structure





Key terminology


The material in this section is based on the XML Specification. This is not an exhaustive list of all the constructs which appear in XML; it provides an introduction to the key constructs most often encountered in day-to-day use.

 (Unicode) Character

By definition, an XML document is a string of characters. Almost every legal Unicode character may appear in an XML document.

Processor and Application

Software which processes an XML document. It is expected that a processor works in the service of an application. There are certain very specific requirements about what an XML processor must do and not do, but none as to the behavior of the application. The processor (as the specification calls it) is often referred to colloquially as an XML parser.

Markup and Content

The characters which make up an XML document are divided into markup and content. Markup and content may be distinguished by the application of simple syntactic rules. All strings which constitute markup either begin with the character "<" and end with a ">", or begin with the character "&" and end with a ";". Strings of characters which are not markup are content.

 Tag

A markup construct that begins with "<" and ends with ">". Tags come in three flavors: start-tags, for example
, end-tags, for example
, and empty-element tags, for example .

Element

A logical component of a document which either begins with a start-tag and ends with a matching end-tag, or consists only of an empty-element tag. The characters between the start- and end-tags, if any, are the element's content, and may contain markup, including other elements, which are called child elements. An example of an element is Hello, world.. Another is .

Attribute

A markup construct consisting of a name/value pair that exists within a start-tag or empty-element tag. In this example, the name of the attribute is "number" and the value is "3": Connect A to B. This element has two attributes, src and alt: by Raphael An element must not have two attributes with the same name.

XML Declaration

XML documents may begin by declaring some information about themselves, as in the following example.

xquery xpath expressions

XQuery uses XPath  expressions to locate nodes in a document and to navigate from one location to another within a single document or across documents. Navigation paths defined using XPath consist of a sequence of steps separated by /. A single step comprises an axis, a node test, and zero or more step qualifiers.

The axis specifies the direction of movement, relative to the context node. Supported axes in SQL Server 2005 are child, descendant, parent, attribute, self and descendant-or-self.

child : the children of the context node





descendant : all descendants (children, childrens children, ...)




parent : the parent (empty if at the root)




ancestor : all ancestors from the parent to the root




following-sibling : siblings to the right




preceding-sibling : siblings to the left




following : all following nodes in the document, excluding descendants

preceding : all preceding nodes in the document, excluding ancestors

attribute : the attributes of the context node

namespace : namespace declarations in the context node

self : the context node itself

descendant-or-self :  the union of descendant and self


ancestor-or-self : the union of ancestor and self

Sub Query

















The SQL subquery feature lets you use the results of one query as part of another query.

A subquery is a query within a query.



A sub-query is a SQL Server statement embedded inside of another SQL Server statement.

Sub-query execution is dependent upon the nesting level of the query. The execution tree goes from inner-most queries to outer-most queries. The higher nested queries can access the results returned by the lower nested queries.


Paranthesis
  • A sub‐query must be enclosed in the parenthesis
comparison operator
  • A sub‐query must be put in the right hand of the comparison operator
Order By
  • A sub‐query cannot contain an ORDER‐BY clause
Number Of SubQuery's
  • A query can contain more than one sub‐query
Types
  • Sub Query
  • Correlated Sub Query
Results
  • Single Row
  • Multipe Row
  • Multiple Columns

Correlated Sub Query Sample
A correlated sub-query is dependent upon the outer query. The outer query and the sub-query are related typically through a WHERE statement located in the sub-query. The way a correlated sub-query works is when a reference to the outer query is found in the sub-query, the outer query will be executed and the results returned to the sub-query. The sub-query is executed for every row that is selected by the outer query.
