プリペアドステートメントに値を渡すときは、パラメータを使用する必要があります。しかし、そうでなければ、日付は一重引用符で囲む必要があります。だから、代わりに：

SET @item1inv = CONCAT('UPDATE running_inventory SET `', item1_id, '` = `', item1_id, '` - ', item1_qty, ' WHERE date = ', invdate); 

それは次のようになります。

SET @item1inv = CONCAT('UPDATE running_inventory SET `', item1_id, '` = `', item1_id, '` - ', item1_qty, ' WHERE date = ''', invdate, '''');
