Implicit conversion from data type varchar to varbinary is not allowed

Error :-Implicit conversion from data type varchar to varbinary is not allowed

Solution :- This Problem Occur when we define the wrong data type declaration for create the table 
Example as Shown Below

CREATE TABLE [dbo].[issue_tab](
 [id] [int] IDENTITY(1,1) NOT NULL,
 [name] [varchar](255) NULL,
 [party] [varchar](255) NULL,
 [address] [text] NULL,
 [related_person] [varchar](255) NULL,
 [type_selection] [varchar](255) NULL,
 [contactno] [VARBINARY(MAX)](10) NULL,
 CONSTRAINT [PK_issue_tab] PRIMARY KEY CLUSTERED 
(
 [id] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF

, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON,

 ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

GO

In this Above table Lock at the highlight contactno coloumn .The datatype is[VARBINARY(MAX)](10) NULL show we get the error .

Result : - So Change the Data Type Like Varchar and According to You Want to Enter From the Form

CREATE TABLE [dbo].[issue_tab](
 [id] [int] IDENTITY(1,1) NOT NULL,
 [name] [varchar](255) NULL,
 [party] [varchar](255) NULL,
 [address] [text] NULL,
 [related_person] [varchar](255) NULL,
 [type_selection] [varchar](255) NULL,
 [contactno] [varchar]](255) NULL,
 CONSTRAINT [PK_issue_tab] PRIMARY KEY CLUSTERED 
(
 [id] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF

, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON,

 ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

GO
