Hi there,
I am not sure if this is possible that automatically let a table feed a stored procedure with parameters:
tableParam has columns:
ID | Year | Month | Week |
A stored procedure run as
exec sp_ClculateValue year, month, week
here year, month and week are the parameters coming from table tableParam with year, month, week order. How can i let the table feed the sp with all parameters in the order of
exec sp_ClculateValue 2010, Jan, week1
exec sp_ClculateValue 2010 Feb, week2
...
exec sp_ClculateValue 2010 Dec week1
...
exec sp_ClculateValue 2011, Jan, week1 ...
exec sp_ClculateValue 2011, Feb, week1
exec sp_ClculateValue 2011, Dec, week1
till all values in tableParam run out?
thanks in advance.

you've to use a cursor based logic in t-sql for this
Is this requirement to do it native sql or one to call from ssis package?

Another method to do is
declare @sql varchar(max)
set @sql=''
select @sql=@sql+' exec sp_ClculateValue '+cast(year as varchar(4))+','+cast(month as varchar(2))+','+cast(week as varchar(4)) from table
order by id
select @sql
If the select gives all you want , add exec(@sql) at the end

if its called from an ssis package you can do the following
1. Create a variable of type object
2. Use an execute sql task to retrieve values from tableparam and populate the object variable
3. Use a For each loop with ADO .NET enumerator and map to above object variable
4. Create three other variables of type int to hold the Year,Month,Week values from loop during each iteration and map inside for each loop
5. Add another execute sql task inside for each loop to call the sp
make the statement as
exec sp_ClculateValue ?, ?, ?
and map to variables in parameter mapping tab as
variable type direction parametername
User::Year long Input 0
User::Month long Input 1
User::Week long Input 2
