Jquery HTML Tag Select


Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero.

* Operator Pointer

Pointer is a special type of variable which hold address of a location in memory. * symbol is use to make pointer. You can manipulate any variable data though pointer from other function. Change will be permanent when it been done with pointer because pointer has actual physical location of a variable.

You can manipulate a variable data using pointer. By
  • First make a pointer variable
  • Assign address of variable to pointer
  • Access variable data though * operator

SQL Server output parameter


Output Parameter

Store procedure is a set of some sql statement which saved on server. Store procedure takes argument for database operation which is known parameter. There are two type of parameter.

Input parameter

When user provides a value as parameter and passes to store procedure.

Output Parameter

When user hold something returns from store procedure through parameter known as output parameter.

Advantage

  • Decrease complexity because it help you to do more than one task in single procedure
  • when inserting data to a table and you need to get the identity value back
  • when perfoming select statements and you need some extra data,
  • when updating or inserting data and you need some way to know if the operation was successful
  • for most if not all of the reasons you need out or ref parameters in c#
