Question

i want to realize a construct in MS SQL that would look like this in Oracles PL/SQL:

declare
asdf number;
begin
for r in (select * from  xyz) loop
   insert into abc (column1, column2, column3) 
   values (r.asdf, r.vcxvc, r.dffgdfg) returning id into asdf;

    update xyz set column10 = asdf where ID = r.ID;
end loop;
end;

Any idea how to realize this would be helpful.

Thanks in advance

Answer 1

declare @asdf int/varchar -- unsure of datatype
declare @vcxvcint/varchar -- unsure of datatype
declare @dffgdfg int/varchar -- unsure of datatype
declare @id int    
declare db_cursor CURSOR FOR SELECT asdf, vcxvc, dffgdfg FROM xyz

OPEN db_cursor
FETCH NEXT FROM db_cursor
INTO @asdf, @vcxvcint, @dffgdfg

WHILE @@FETCH_STATUS = 0
BEGIN    
  insert into abc (column1, column2, column3) values (@asdf, @vcxvcint, @vcxvcint)    
  set @id = scope_identity() -- This will get the auto generated ID of the last inserted row
  update xyz set column10 = @asdf where id = @    
  FETCH NEXT FROM db_cursor INTO @name    
END

CLOSE db_cursor
DEALLOCATE db_cursor

Of course basically all DBA’s will kill you if you try and sneak a cursor into production code.
