Unfortunately, SQL Server does not support user-defined global variables. Modules, and therefore module variables, do not even exist in Transact-SQL. One way to pass a recordset is to create and fill a temporary table. Inner stored procedures will be able to see and access its content. The following example consists of two stored procedures. The first is business-oriented and collects a list of properties associated with an inventory asset. The list is implemented as a temporary table:

The nested stored procedure is not business-oriented. It loops through records in the temporary table (which was created in calling the batch or stored procedure) and assembles them into a single varchar variable:

You can execute this example from Query Analyzer, as shown in Figure 10-5. You may ask when is this kind of solution justified and are these stored procedures coupled It is true that neither of these stored procedures can function without the other. If we have other stored procedures that also use prConvertTempTbl, I would consider this solution justified.

Using temporary tables to pass a recordset to a nested stored procedure

Using a Cursor to Pass a Recordset to a Nested Stored Procedure
Similar solutions can be implemented using cursors. Cursors are also visible and accessible from nested stored procedures. The following example also consists of two stored procedures. The first is business-oriented and creates a cursor with properties associated with specified inventory.
create Procedure prGetInventoryProperties_Cursor_Nested /* Return comma-delimited list of properties that are describing asset. i.e.: Property = Value unit;Property = Value unit;Property = Value unit; Property = Value unit; Property = Value unit; Property = Value unit; */ ( @intInventoryId int, @chvProperties varchar(8000) OUTPUT, @debug int = 0 ) As Select @chvProperties = '' Declare curItems Cursor For Select Property + '=' + [Value] + ' ' + Coalesce([Unit], '') + '; ' Item From InventoryProperty Inner Join Property On InventoryProperty.PropertyId = Property.PropertyId Where InventoryProperty.InventoryId = @intInventoryId Open curItems Exec prProcess_Cursor_Nested @chvProperties OUTPUT, @debug
SQL Server 2000 Stored Procedure Programming
Close curItems Deallocate curItems Return 0 Go
The second stored procedure is generic and converts information from cursors into a single variable:
Create Procedure prProcess_Cursor_Nested -- Process information from cursor initiated in calling sp. -- Convert records into a single varchar. ( @chvResult varchar(8000) OUTPUT, @debug int = 0 ) As Declare @intCountProperties int, @intCounter int, @chvItem varchar(255), @insLenItem smallint, @insLenResult smallint Fetch Next From curItems Into @chvItem While (@@FETCH_STATUS = 0) Begin If @debug <> 0 Select @chvItem Item -- check will new string fit Select @insLenItem = DATALENGTH(@chvItem), @insLenResult = DATALENGTH(@chvResult) If @insLenResult + @insLenItem > 8000 Begin Select 'List is too long (over 8000 characters)!' Return 1 End
