存储过程解析表菜单并输出JSON格式字符串

2024-07-26 06:06:35 221人阅读

表结构如下：

SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [dbo].[T_4s_Menu](
	[F_MenuID] [int] IDENTITY(1,1) NOT NULL,
	[F_MenuName] [nvarchar](50) NULL,
	[F_MenuUrl] [varchar](100) NULL,
	[F_ParentID] [int] NULL,
	[F_MenuCode] [varchar](10) NULL,
	[F_Order] [int] NULL,
	[F_IsMenu] [bit] NULL,
	[F_IsWindow] [bit] NULL,
 CONSTRAINT [PK_T_4s_Menu] PRIMARY KEY CLUSTERED 
(
	[F_MenuID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
SET ANSI_PADDING OFF
GO

存储过程如下：

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

结果如下：

然后前台就可以通过JS解析来构建菜单了。
