Question

In my stored procedure I declared two table variables on top of my procedure. Now I am trying to use that table variable within a dynamic sql statement but I get this error at the time of execution of that procedure. I am using Sql Server 2008.

This is how my query looks like,

set @col_name =  'Assoc_Item_' 
              + Convert(nvarchar(2), @curr_row1);

set @sqlstat = 'update @RelPro set ' 
             + @col_name 
             + ' = (Select relsku From @TSku Where tid = ' 
             + Convert(nvarchar(2), @curr_row1) + ') Where RowID = ' 
             + Convert(nvarchar(2), @curr_row);

Exec(@sqlstat);

And I get the following errors,

Must declare the table variable “@RelPro”.
Must declare the table variable “@TSku”.

I have tried to take the table outside of the string block of dynamic query but to no avail.

Your EXEC executes in a different context, therefore it is not aware of any variables that have been declared in your original context. You should be able to use a temp table instead of a table variable as shown in the simple demo below.

create table #t (id int)

declare @value nchar(1)
set @value = N'1'

declare @sql nvarchar(max)
set @sql = N'insert into #t (id) values (' + @value + N')'

exec (@sql)

select * from #t

drop table #t
