The edit page populates, but when I hit ‘Submit’ It brings up the Error "incorrect syntax near ‘Make’. When I put a breakpoint on the command.Parameters.AddWithValue("Make", car.Make); it has the correct value of "Honda".

The start of the HTML form is:

<form method="POST">
<input type="hidden" name="Id" value="@Model.car.Id" />
<div class="row mb-3">
    <label class="row mb-3"></label>
        <label class="col-sm-3 col-form-label">Make</label>
        <div class="col-sm-6">
            <input type="text" class="form-control" name="Make" value="@Model.car.Make" />
        </div>
</div>

This is the table in the sql database:

CREATE TABLE [dbo].[listCars] (
[Id]           INT             IDENTITY (1, 1) NOT NULL,
[Make]         NVARCHAR (MAX)  NULL,
[CarModel]     NVARCHAR (MAX)  NULL,
[Year]         INT             NOT NULL,
[Colour]       NVARCHAR (MAX)  NULL,
[Registration] NVARCHAR (MAX)  NULL,
[Price]        DECIMAL (18, 2) NOT NULL,
CONSTRAINT [PK_listCars] PRIMARY KEY CLUSTERED ([Id] ASC)

);

I have looked over this and tried to find solutions for hours with no luck.

>Solution :

string sql = "UPDATE listCars" +
             " SET Make=@Make, CarModel=@CarModel, Year=@Year, Colour=@Colour, Registration=@Registration, Price=@Price" + 
             " WHERE Id=@Id";

You missed a space between the table name and SET, the same goes for WHERE.
