mysql - フィールド リストの不明なテーブル (vb.net の MySQL)

Question

MySql.Data.MySqlClient.MySqlCommand と MySqlConnection を使用します

Public fillGridCmdTxt As String = "SELECT tblItems.part_num AS Part#, tblCategory.category_description AS Category, " _
            & " tblItems.item_name AS 'Item Name', tblItems.item_desc AS Description, " _
            & "tblItems.item_qty AS Qty, tblUnit.unit_name AS Unit, tblItems.item_price AS 'Selling Price(Php)' " _
            & "FROM tblUnit INNER JOIN tblItems ON tblUnit.unit_id = tblItems.unit_id INNER JOIN tblCategory " _
            & "ON tblItems.category_id = tblCategory.category_id "

MySqlCommandでexecuteNonQueryを使用すると、エラーが発生します...「不明なテーブル '* tblItems in field list *」と表示されますが、テーブルはデータベースに実際に存在します...少し助けてください?
