Table-valued parameters offer more flexibility and in some cases better performance than temporary tables or other ways to pass a list of parameters.Table-valued parameters offer the following benefits: Using table-valued parameters is comparable to other ways of using set-based variables; however, using table-valued parameters frequently can be faster for large data sets.ID.value('.','VARCHAR(20)') FROM @Expense Report IDs.nodes('/Root/Expense Report ID') as Param Values(ID) INSERT INTO #ERTemp Table (Expense Report ID) SELECT Param Values.ID.value('.','VARCHAR(20)') FROM @Expense Report IDs.nodes('/Root/Expense Report ID') as Param Values(ID) UPDATE #ERTemp Table SET Expense Report Project ID = ( SELECT TOP 1 Expense Report Project ID FROM Expense Report Item WHERE(Expense Report ID = #ERTemp Table.When I attempt to update further fields in the temp tables the Table Variable fails but the Temp Table has no problem with the Update Statement. I would like to take advantage of the speed boost that Table Variables promise…
BULK INSERT Operations Example A table-valued parameter is scoped to the stored procedure, function, or dynamic Transact-SQL text, exactly like other parameters.
Transact-SQL passes table-valued parameters to routines by reference to avoid making a copy of the input data.
You can create and execute Transact-SQL routines with table-valued parameters, and call them from Transact-SQL code, managed and native clients in any managed language.
State what version of SQL Server you are using and specify the content of any error messages.
I have been reading about the differences between Table Variables and Temp Tables and stumbled upon the following issue with the Table Variable.
