    declare @ParenttableData table (id uniqueidentifier);

    set @UserId =(select UserId from Users where UserName= @Username)

    BEGIN

                insert into parenttable(
                    Parenttableid,
                    UserId

                )
                output inserted.Parenttableid into @parentTableData(id)
                values (
                    NEWID(),
                    @UserId,

                );

                select @parenttableid = id from @ParenttableData;

                insert into items(
                  parenttableid,
                    itemsID,

                )
                values (
                    @parenttableid,
                    NEWID()
