将OLEDB转换为SQL Server之后的.updateall中的SqlException

Question

I'm writing an app in C# with a MS Access backed ( .accdb ). I made the call (on advisement) that SQL Server was a much better idea for my system, thus I spent the last 8 hrs re-coding to SQL Server.

As a background;

• Changed all OLEDB connection, command etc etc to Sql
• Fixed all parameters and variables from ? to @value
• Fixed all SQL string errors

Now all my forms are working with the exception of the ones using BINDING done by Visual Studio 'wizard' (if that's what it's called).

I have 5 forms which are filled using

this.tbljobTableAdapter.Fill(this.websterdbDataSet.tbljob);

They are all using a DataGridView depending upon that info.

On "Save and Close", this code runs:

this.Validate();
this.tbluserBindingSource.EndEdit();

this.tableAdapterManager.UpdateAll(this.websterdbDataSet);

_owner.PerformRefresh();
this.Close();
this.Dispose();

This works 100% still with my .ACCDB version (I'm checking from a backup) but not now that it is SQL Server.

If I press Save and Close and haven't changed ANYTHING, it closes, but if I change any field at all it fails with this (from my log):

Data Time:21/08/2017 12:12:20 AM
Exception Name:Incorrect syntax near '`'.
Event Name:System.Windows.Forms.MouseEventArgs
Control Name:BtnSave
Error Line No.:86
Form Name:frmjoblist

Any ideas how I can further debug this?

I thought it was something I did when adding Try and Catch to all my sections, but in the end this is happening to the specific 5 forms that I used the wizard instead of manually creating, binding and writing SQL update strings for.

Thanks for any advice/direction.

因此，设计者仍然全部在OLEDB中，因此我最终删除了数据集并使用正确的连接重新创建，从而在SQL中重建了设计器
