Cursor - Changing name table

Hallo, is it possible write statement with some parameter in after definition of cursur ?
I usually work with cursor, but in cycle i need to change name of table


Declare au_cursor Cursor

FOR

SELECT id,tabs FROM k_Tabs
Open au_cursor
Fetch Next FROM au_cursor into @id, @tabs

WHILE (@@FETCH_STATUS = 0)

BEGIN

Set @tmp= @tabs ' @tmp is name of table which i reed from another table and work with it

Declare ns_cursor Cursor
FOR

set @sqlCommand='Select ns, price from '+@tmp
execute(@sqlCommand)

Open ns_cursor
Fetch Next From ns_cursor into @ns,@cena

WHILE (@@FETCH_STATUS = 0)
BEGIN
.
.
.
Fetch Next From zar_cursor into @program,@interval1,@interval2,@zlavaPerc
END
Close ns_cursor
Deallocate ns_cursor
.
.
.
Fetch Next FROM au_cursor into @id, @tabDatabaza
END

Close au_cursor
Deallocate au_cursor
