This project is a collection of tools for use with the spatial types in SQL Server. This project does not provide an end-user application, but rather a set of reusable functions which applications can make use of. These functions may include data conver
In this chapter, we will discuss Variables in Pl/SQL. A variable is nothing but a name given to a storage area that our programs can manipulate. Each variable in PL/SQL has a specific data type, which determines the size and the layout of the variable's memory; the range of values th...
