关于操作Access数据报System.Data.OleDb.OleDbException: INSERT INTO 语句的语法错误异常问题
关于操作Access数据报System.Data.OleDb.OleDbException: INSERT INTO 语句的语法错误异常问题
这两天答应朋友给他做个单机版的管理系统，所以数据库选用Access，以往的开发都是选用的SQL-Server，不过他们都是微软的，使用应该没什么问题。可是在我进行数据插入时，系统报System.Data.OleDb.OleDbException: INSERT INTO 语句的语法错误异常问题，仔细查看Insert语句，找不到“语法错误”，
数据库名：Grade.mdb
字段：CID char
CName char
Note char
代码如下：
#region 数据库连接
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
//插入新数据
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;
}
运行报异常，上网查了好多资料，才晓得字段Note居然时Access的关键字，而在SQL-Server中可以正常使用，郁闷，只要将Insert语句改成
Insert Into CollegeInfo (CID, CName, [Note]) Values ('a11','aaa','bbb')
即可！
所以我把问题贴出来，如果有网友遇到此类问题，可以检查字段是否为关键字。
