我在通过 C# OleDbCommand 对 Access 后端表运行插入查询时遇到问题。如果您复制它并直接在 Access 中运行，SQL 运行良好，并且在点击此特定条目之前它适用于其他数据。

我曾尝试更改数据，但没有成功。其来源是一个 XML 文件。XML 数据正在正确加载。

失败的命令是带有错误“INSERT INTO 语句中的语法错误”的 dbCommand.ExecuteNonQuery()。

dbCommand = new OleDbCommand(string.Format(INSERT_RECURRING, tableName, fieldList, valueList), dbCon);
dbCommand.ExecuteNonQuery();

下面是尝试运行但失败的 SQL。请注意，表和字段名称是从 XML 源文件生成的，因此需要大写和下划线。

INSERT INTO LIST_CONTACTSGP (RID, CONTACT_TYPE, SURNAME_OR_FAMILY_NAME, GIVEN_NAMES, ORGANISATION, ADDRESS_GP, PHONE, MOBILE, WORK, FAX, EMAIL, COMMENTS) VALUES ('1-8HZAZN', 'Daughter, Other Emergency Contact', 'Smith', 'Ms Jenny', '', '', '49123456', '0416123456', '', '', '', '');

正如我之前提到的，此 SQL 在 Access 中运行不会失败，并且在此失败之前其他插入命令（在其他表上）工作正常。我删除了所有可能导致问题的 SQL 特殊字符。

任何帮助将不胜感激。

好的，我有一个答案（感谢 ralf.w）。非常感谢 AVD 和 Remou 花时间帮助解决这个问题。

列名需要封装在方括号中。尽管使用其他表并直接在 Access 中工作正常，但通过 OleDbCommand 发送它时，一个（或多个）列名肯定会导致问题。

所以 SQL 代码应该是：

string sql="INSERT INTO LIST_CONTACTSGP ([RID], [CONTACT_TYPE], [SURNAME_OR_FAMILY_NAME], 
            [GIVEN_NAMES], [ORGANISATION], [ADDRESS_GP], [PHONE], [MOBILE], [WORK], [FAX], [EMAIL], 
            [COMMENTS]) VALUES (@RID, @CONTACT_TYPE, @SURNAME_OR_FAMILY_NAME, 
            @GIVEN_NAMES, @ORGANISATION, @ADDRESS_GP, @PHONE, @MOBILE, @WORK, @FAX, 
             @EMAIL, @COMMENTS)";

使用parameters而不是字符串连接。

string sql="INSERT INTO LIST_CONTACTSGP (RID, CONTACT_TYPE, SURNAME_OR_FAMILY_NAME, 
            GIVEN_NAMES, ORGANISATION, ADDRESS_GP, PHONE, MOBILE, WORK, FAX, EMAIL, 
            COMMENTS) VALUES (@RID, @CONTACT_TYPE, @SURNAME_OR_FAMILY_NAME, 
            @GIVEN_NAMES, @ORGANISATION, @ADDRESS_GP, @PHONE, @MOBILE, @WORK, @FAX, 
             @EMAIL, @COMMENTS)";

using(OleDbCommand dbCommand = new OleDbCommand(sql,conn))
{
  dbCommand.Parameters.Add("@RID",OleDbType.VarChar,20).Value="10";
  dbCommand.Parameters.Add("@CONTACT_TYPE",OleDbType.VarChar,20).Value="Somethig";
  .....
  conn.Open();
  dbCommand.ExecuteNonQuery();
  conn.Close();
}
