c# - SqlException in .updateall after convert OLEDB to SQL Server -


i'm writing app in c# ms access backed (.accdb). made call (on advisement) sql server better idea system, spent last 8 hrs re-coding sql server.

as background;

  • changed oledb connection, command etc etc sql
  • fixed parameters , variables ? @value
  • fixed sql string errors

now forms working exception of ones using binding done visual studio 'wizard' (if that's it's called).

i have 5 forms filled using

this.tbljobtableadapter.fill(this.websterdbdataset.tbljob);

they using datagridview depending upon info.

on "save , close", code runs:

this.validate(); this.tbluserbindingsource.endedit();  this.tableadaptermanager.updateall(this.websterdbdataset);  _owner.performrefresh(); this.close(); this.dispose();

this works 100% still .accdb version (i'm checking backup) not sql server.

if press save , close , haven't changed anything, closes, if change field @ fails (from 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 can further debug this?

i thought did when adding try , catch sections, in end happening specific 5 forms used wizard instead of manually creating, binding , writing sql update strings for.

thanks advice/direction.
