我正在创建一个具有 Sql 查询通知的应用程序，但我遇到了一个问题.. 系统一直在循环，进入无限循环。我使用的查询在存储过程中，我使用了 7我的查询中的表。我的查询或我的应用程序似乎有什么问题？请帮我解决这个问题谢谢:)我会在这里发布我的代码这是我正在使用的存储过程
ALTER PROCEDURE [dbo].[INVENTORYLOG_VIEW]
AS
BEGIN
SELECT
ACCOUNT.Emp_Fname + ' ' + ACCOUNT.Emp_Lname AS [USERS],
INVENTORYLOG.ACTIVITYDATE AS [ACTIVITY DATE],
INVENTORYLOGDETAILS.ACTIVITYTIME AS [ACTIVITY TIME],
INVENTORYLOGDETAILS.LOG_ACTION AS [USER LOG],
CATEGORY.CATEGORY_NAME,
BRAND.Brand_Name AS BRAND,
PRODUCTDESCRIPTION.DESCRIPTION_TYPE,
COLOR.Color_Name AS [COLOR NAME],
SIZES.SIZE,
INVENTORY.QUANTITY_ON_HAND AS [CURRENT QTY],
INVENTORYLOGDETAILS.QUANTITY_LOG_ACTION AS [USER LOG QTY]
FROM
dbo.ACCOUNT INNER JOIN
dbo.INVENTORYLOG ON dbo.ACCOUNT.ACCOUNT_ID = dbo.INVENTORYLOG.Account_Id INNER JOIN
dbo.INVENTORYLOGDETAILS ON dbo.INVENTORYLOG.INVENTORYLOGID = dbo.INVENTORYLOGDETAILS.INVENTORYLOGID INNER JOIN
dbo.INVENTORY ON dbo.INVENTORYLOGDETAILS.INVENTORY_ID = dbo.INVENTORY.INVENTORY_ID INNER JOIN
dbo.PRODUCT_DTL ON dbo.INVENTORY.PRODUCT_DTL_ID = dbo.PRODUCT_DTL.PRODUCT_DTL_ID INNER JOIN
dbo.COLOR ON dbo.PRODUCT_DTL.COLOR_ID = dbo.COLOR.Color_Id INNER JOIN
dbo.BRAND ON dbo.PRODUCT_DTL.BRAND_ID = dbo.BRAND.Brand_Id INNER JOIN
dbo.CATEGORY ON dbo.PRODUCT_DTL.CATEGORY_ID = dbo.CATEGORY.CATEGORY_ID INNER JOIN
dbo.PRODUCTDESCRIPTION ON dbo.PRODUCT_DTL.DESCRIPTION_ID = dbo.PRODUCTDESCRIPTION.DESCRIPTION_ID INNER JOIN
dbo.SIZES ON dbo.PRODUCT_DTL.SIZE_ID = dbo.SIZES.SIZE_ID
END
