Lesson 1: Connect to a database and start the debugger Next Page

Lesson 2: Debug a stored procedure

This lesson illustrates how to use the debugger to identify errors in stored procedures. To set the stage, you introduce a deliberate error into the debugger_tutorial, which is part of the SQL Anywhere sample database.

The debugger_tutorial procedure should return a result set that contains the name of the company that has placed the highest value of orders, and the value of their orders. It computes these values by looping over the result set of a query that lists companies and orders. (This result could be achieved without adding the logic into the procedure by using a SELECT FIRST query. The procedure is used to create a convenient example.) The procedure has an intentional bug in it. In this tutorial you diagnose and fix the bug.
