Nested Stored Procedures Two tricks can help you debug a set of nested stored procedures (that is, when a stored procedure calls another stored procedure). It is a useful practice to display the name of the stored procedure at the beginning and end of the stored procedure.

declare @chvProcedure sysname set @chvProcedure = 'prGetInventoryProperties_2' if @debug <> 0 select '**** '+ @chvProcedure + 'START ****' ... if @debug <> 0 select '**** '+ @chvProcedure + 'END ****' return 0

Systems with hundreds of megabytes of RAM are not uncommon. In fact, for benchmark activities, Microsoft runs programs under development with a memory configuration of as much as 2GB of physical RAM. Using SQL Server on a DEC Alpha processor, or using the Enterprise Edition of SQL Server, allows even more

When you call a nested stored procedure, you need to pass the value of the @debug parameter to it as well. In this way, you will be able to see its debugging information.

You should keep the following issues in mind when you are writing your code and testing Transact-SQL programs:

NULLS Assignment of variable from resultset No records affected Wrong size or datatype Default length Rollback of triggers Warnings and lower-priority errors Nested comments Deferred name resolution Cursors Overconfidence

During the load, the BulkLoad component will write fatal and nonfatal errors to the file specified by the ErrorLogFile property. The file is naturally an XML document:

Many errors are a result of the inadequate treatment of NULL values in Transact-SQL code. Developers often forget that local variables or table columns might contain NULLs. If such a value becomes part of any expression, the result will also be NULL. The proper way to test the value of an expression for NULLs is to use the IS NULL or IS NOT NULL clauses. Microsoft SQL Server treats

7:

the use of = NULL as another way to type IS NULL, but <> NULL is not the equivalent of IS NOT NULL. The result of such an expression is always simply NULL. It will never be true, and stored procedures will always skip statements after the If statement when you use the <> NULL clause.

If @intInventoryId IS NULL ... If @intInventoryId = NULL ... If @intInventoryId IS NOT NULL ... If @intInventoryId <> NULL ... -- WRONG!!!

Earlier, we discussed assigning the value(s) for a variable(s) using the resultset of the Select statement. This technique is fine when the resultset returns precisely one record. However, if the resultset returns more than one record, the variable(s) are assigned using the value(s) from the last record in recordset. Not perfect, but in some cases, you can live with it. It is sometimes difficult to predict which record will be returned as last in the recordset. It depends on the query and the index that SQL Server has used. A more serious problem occurs when the recordset is empty. The values of the variables are changed in this case, and the code is vulnerable to several mistakes. If you do not expect the resultset to be empty, your stored procedure will fail. If you expect the values of the variables to be NULL, your stored procedure will function correctly only immediately after it is started (that is, in the first iteration of the process). In such a case, the local variables are not yet initialized and will contain NULLs. Later, when variables are initialized, their values will remain unchanged. If you are testing the contents of the variables for NULLs to find out if the record was selected, you will just process the previous record again.

Developers sometimes assume that SQL Server will return errors if a Transact-SQL statement affects no records. Unfortunately, this error is semantic rather than syntactic and SQL Server will not detect it. In order to determine such an error, use the @@rowcount function rather than the @@error function:
