Exception in syntax error of operating access datagram system. Data. oledb. oledbexception: insert into statement

Exception in syntax error of operating access datagram system. Data. oledb. oledbexception: insert into statement

In the past two days, I promised my friend to create a standalone version of the management system for him. Therefore, access is used for databases. In the past, SQL-server was used for development. However, they are all from Microsoft, so it should be okay to use them. However, when I insert data, the system reports system. Data. oledb. oledbexception: the syntax error of the insert into statement. Check the insert statement carefully and the "syntax error" cannot be found ",
Database Name: grade. MDB
Field: Cid char
Cname char
Note char
CodeAs follows:

# Region database connection

Public class dbconnection
{
Private oledbconnection conn;

Public oledbconnection oledbconn
{
Get
{
String Path = directory. getcurrentdirectory ();
String connstring = "provider = Microsoft. Jet. oledb.4.0;" +
"Data Source =" + path + "http://www.cnblogs.com/ForEverKissing/admin/file://grade.mdb ";
If (conn = NULL)
Conn = new oledbconnection (connstring );
Return conn;
}
}
}

# Endregion

// Insert new data
Public int addnewinfo ()
{
Oledbconnection myconn = dbconn. oledbconn;
Int val = 0;
Try
{
Myconn. open ();
String myinsertstring = "insert into collegeinfo (CID, cname, note)" +
"Values ('a11', 'aaa', 'bbb ')";
Oledbcommand cmd = new oledbcommand (myinsertstring, myconn );
Val = cmd. executenonquery ();
}
Catch (exception ex)
{
MessageBox. Show ("error:" + ex. tostring ());
Val =-1;
}
Finally
{
Myconn. Close ();
}
Return val;
}
When an exception is reported during running, I checked a lot of information on the Internet to find out the keyword of access when the field note is used. In SQL Server, the keyword can be used normally. If it is depressing, I only need to change the insert statement
Insert into collegeinfo (CID, cname, [note]) values ('a11', 'aaa', 'bbb ')
You can!

So I posted the problem. If a netizen encounters such a problem, you can check whether the field is a keyword.

It seems that there are still a lot of access keywords. Thanks to songmeiying.
