This is a common error occurred during the database operation in ADO.Net. The cause for this error is the column name matches some reserved words. To solve this issue suffix and prefix with “] and [” in column names.

Command object

OleDbCommand cmd = new OleDbCommand(“insert into acgroup(gname,parent,[note]) values(‘” + gname + “‘,'” + gparent + “‘,'” + gdescription + “‘” + “)”, Globals.con);
cmd.ExecuteScalar();

here ‘note’ cause the error.

Dataset and Command builder

If you are using dataset, adapter and command builder to insert records, use command builder Quickfix method to solve the issue as follows

dr = Globals.GroupDataSet.Tables[0].NewRow();
dr[“gname”] = gname;
dr[“parent”] = gparent;
dr[“note”] = gdescription;
Globals.cmdbuilder = new OleDbCommandBuilder(Globals.GroupAdapter);
Globals.cmdbuilder.QuotePrefix = “[“;
Globals.cmdbuilder.QuoteSuffix = “]”;
Globals.GroupDataSet.Tables[0].Rows.Add(dr);
Globals.GroupAdapter.InsertCommand = Globals.cmdbuilder.GetInsertCommand();
int stat = Globals.GroupAdapter.Update(Globals.GroupDataSet.Tables[0]);
if (stat > 0)
{
MessageBox.Show(“Group Information saved”);
