From data type varchar to varbinary is not allowed

The issue:

Insert into tb_Admin values (1Jing 111, 'ricky',1234)

Implicit conversion from data type varchar to varbinary is not allowed. Use the CONVERT function to run this query.

Root Cause: the column 'AdminName' define as varbinary.

-- The table structure:CREATE TABLE [dbo]. [tb_Admin] ([ID] [int] NOT NULL, [AdminNum] [varchar] (50) NULL, [AdminName] [varbinary] (50) NULL, [AdminPwd] [varbinary] (50) NULL, CONSTRAINT [PK_tb_Admin] 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] GO

Resolution:

Insert into tb_Admin (ID,AdminNum,AdminName,AdminPwd) values (1mem111 as varbinary cast ('name' as varbinary (50)), cast (' 1234' cast (50)

Result1:

ID AdminNum AdminName AdminPwd

1 111 0x6E616D65 0x31323334

Search the original information:

SELECT TOP 10 [ID], [AdminNum], cast ([AdminName] as varchar (50)), cast ([AdminPwd] as varchar (50)) FROM [db_ExamOnline]. [DBO]. [TB _ Admin]

Result2:

ID AdminNum (No column name) (No column name)

1 111 name 1234
