Samples of SPís

This section is a tutorial aimed at explaining how stored procedures work through practical examples. Each piece of code is followed by a screenshot, showing the actual output from running the code in Query Analyzer.

The examples are identical or very similar to the ones from the chapter ďIntroduction to Extended Stored ProceduresĒ with the evident difference that they are coded in TSQL. The advantages of having stored procedures (SPís) functionally equivalent to XPís are:

* C++ programmers can learn more about SPís and TSQL by first understanding XPís because of their familiarity with C++.

* TSQL programmers can learn more about XPís and C++ by relating the parts of the code of an SP with its equivalent XP.

* Comparing SPís and XPís for performance, development time, maintenance issues, etc. is essential for understanding the differences between them.

XPís are not always a better choice than SPís; for simple tasks they will do as well as XPís but with less effort and time involved in the development. SPís and XPís will coexist and work together, like the infantry and artillery from the army of database tools.
