How to Debug your Stored Procedure?
In many cases, you might want to test your SP on various scenarios and go through each step on how your data gets changed at each step. The below steps should help you to achieve the goal:
a) Go to SQL Enterprise Manager -> Query Analyzer
b) Click on Object Browser link (1) on the Top Menu to display all the databases in your Server
c) Browse through to your Stored Procedure from the Left menu.
d) Select your SP and right click.
e) Select the Option “Debug”.
f) The “Debug Procedure” dialog box shows up with options to enter your test data in “Value” for the selected input parameter displayed in “Parameters”. If you have multiple input parameters, select each parameter and enter valid values. You could select the checkbox “Set to NULL”, if the input parameter can accept NULL values. The debug procedure also displays the “Parameter Type” and the direction (input or output) of the variable.
g) Once the input parameters are entered, click on “Execute”.
h) The SP will be displayed on the SQL pane and the “Debug” arrow shows up on the first line.
i) You will be able to see your input parameters passed on to the variables and also any other variables that you are using in your Stored Procedure.
j) You can debug to the next step by pressing “F10”
k) You can use “F5” to execute all the steps in SP without toggling at each step.
l) You can use “F11” to “step into” each step i.e., if you go one step further inside the current step to debug especially if you have used any other SP in your SP.
m) There are many other options for debugging and you can find them at the top of your SQL pane.
