The Step Out (SHIFT-F11) command enables you to execute the rest of the nested stored procedures without pause and halts only when the stored procedure is completed in the calling stored procedure. Run To Cursor (CTRL-F10) enables you to position the cursor somewhere in the code and to execute everything to that point in a single step. It is also possible to use breakpoints in Query Analyzer. As we explained earlier, breakpoints are markers in code that serve to stop execution when certain conditions are met. In TSQL Debugger, the only such condition is when the execution has reached the position of the breakpoint. To set (or remove) a breakpoint, a user can click a line of code and then click the Toggle Breakpoints button (or press F9). Again, the program marks the breakpoint with a big red dot at the beginning of the line. Then, the user can simply run the procedure using the Go button (F5). It is not necessary to step through the code. The program stops execution when it encounters a breakpoint.

NOTE: T-SQL Debugger in Query Analyzer has one small limitation it is not possible to open more then one T-SQL Debugger. Only one stored procedure can be debugged at a time (along with the procedures that are nested in it).

You can debug your stored procedures even if you do not have TSQL Debugger (that is, if your environment does not comply with all the requirements). Before debuggers became part of the programming environment, developers used simple techniques to print the contents of variables and follow the execution of code. Some programming languages include commands (for instance, Assert in Visual Basic 6.0) that are active only during debugging. In others, you simply add print commands during the development stage and comment them out before releasing the code into production. In Transact-SQL, I use a very simple technique that allows me to view the contents of the variables and recordsets when I am testing a stored procedure from Query Analyzer. I add

I do not use the Print statement for this purpose because
w s v
It does not support the display of resultsets. In older versions, it was impossible to concatenate a string inside a Print statement. Some utilities handle messages from the Print statement differently than they do the resultset from the Select statement.
In the following example, you can see a stored procedure that is designed to support this kind of testing:
Alter Procedure prGetInventoryProperties_2 -- Return comma-delimited list of properties -- which are describing asset. -- i.e.: Property=Value unit;Property=Value unit;... @intInventoryId int, @chvProperties varchar(8000) OUTPUT, @debug int = 0 ) As (
