ISNULL()

It replace the NULL with the specified replacement value. The value of check_expression is returned if it is not NULL; otherwise, replacement_value is returned after it is implicitly converted to the type of check_expression, if the type is different.

Syntax

ISNULL ( check_expression , replacement_value )

check_expression

The expression to be checked for NULL. check_expression can be of any type.

replacement_value

Is the expression to be returned if check_expression is NULL. replacement_value must be of a type that is implicitly convertible to the type of check_expresssion.

COALESCE()

Returns the first nonnull expression among its arguments.

Syntax

COALESCE ( expression [ ,...n ] )

expression

It'can be of any type.

Note:
ISNULL()
and COALESCE() though both are equivalent, but they behave differently. An expression involving ISNULL with non-null parameters is considered to be NOT NULL, while expressions involving COALESCE with non-null parameters is considered to be NULL.

For More Inforamtion :

ISNULL() or COALESCE()?

Performance: ISNULL vs. COALESCE

How To Use The Order By Clause When Using UNION ALL Clause

SELECT TOP 1000000000 au_id, au_lname, au_fname,state from authors where state = 'CA' ORDER BY au_lname
union all
SELECT TOP 1000000000 au_id, au_lname, au_fname,state from authors where state = 'UT' ORDER BY au_lname


Msg 156, Level 15, State 1, Line 4
Incorrect syntax near the keyword 'union'.


To Over Come Problem use derived tables, think of these as a self-contained table, a bit like a temporary table within the query

SELECT * FROM (SELECT TOP 1000000000 au_id, au_lname, au_fname,state from authors where state = 'CA' ORDER BY au_lname) AS TEMP_COL_1
UNION ALL
SELECT * FROM (SELECT TOP 1000000000 au_id, au_lname, au_fname,state from authors where state = 'UT' ORDER BY au_lname) AS TEMP_COL_2,


when we want to use order by clause within the particular query then we need top else we will get the following error,
"
Msg 1033, Level 15, State 1, Line 1
The ORDER BY clause is invalid in views, inline functions, derived tables, and subqueries, unless TOP is also specified.
Msg 1033, Level 15, State 1, Line 3
The ORDER BY clause is invalid in views, inline functions, derived tables, and subqueries, unless TOP is also specified."

Attributes Of Highly Effective Programmers - Quality Of A Developer - Self-criticism

Today I had come across two articles and I feel that its good and all the programmers should read this articles.I like to share this for my blog readers.I'm posting the abstract here, so through the orginal articles.

Top 5 Attributes of Highly Effective Programmers

  • Humility
  • Love of Learning
  • Detail-orientedness
  • Adaptability
  • Passion

The most important quality of a developer: Self-criticism

"Don't just implement the first design you come out with, but try and refine looking at it from different angles before to start writing code.

Don't just release the first piece of code you come out with, but do a self review and try to make it clearer and better.

The best developers/architects are the ones that always criticized their own work in order to make it better."

What Is Stored Procedure Part - I

Stored procedures have a segment of code which contains declarative or procedural SQL statement. A stored procedure is resided in the catalog of the database, we can invoke (call) it from a program, stored procedure or even from a trigger.


Stored Procedure contains sql statements like insert, update and delete. In addition stored procedure supports If and while statements.

Advantages:
Once we created Stored Procedure then it can be reused over and over again by multiple applications.

Stored Procedure increase the performance of the application because once it compiled successfully then it’s stored in database catalog. When applications call them, they generally execute faster when compared with un-compiled SQL Statements which are sent from the applications.

Network Traffic between application server and database server is also signification reduced when compared with un-compiled SQL Statements which are sent from the applications.

Syntax
CREATE PROC [ EDURE ] [ owner. ] procedure_name [ ; number ]
[ { @parameter data_type }
[ VARYING ] [ = default ] [ OUTPUT ]
] [ ,...n ]

[ WITH
{ RECOMPILE ENCRYPTION RECOMPILE , ENCRYPTION } ]

[ FOR REPLICATION ]

AS sql_statement [ ...n ]

owner:
Is the name of the user ID that owns the stored procedure. owner must be either the name of the current user or the name of a role that a current user is a member.

procedure_name:
Is the name of the new stored procedure, procedure name cannot exceed 128 characters.
@parameter:
Is a parameter in the procedure. One or more parameters can be declared in a CREATE PROCEDURE statement. The value of each declared parameter must be supplied by the user when the procedure is .A stored procedure can have a maximum of 2,100 parameters. Specify a parameter name using an at sign (@) as the first character.

OUTPUT:
Indicates that the parameter is a return parameter.

;number:
Is an optional integer used to group procedures of the same name so they can be dropped together with a single DROP PROCEDURE statement.
