C# OleDBCommand SQL 语法错误

Question

我在通过 C# OleDbCommand 向 Access 后端表运行插入查询时遇到问题。如果您将 SQL 复制并直接在 Access 中运行，则该 SQL 可以正常运行，并且在命中此特定条目之前它可以很好地处理其他数据。

我试过更改数据，但没有成功。其来源是一个 XML 文件。正在正确加载 XML 数据。

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();

下面是试图运行但失败的 SQL。请注意，表名和字段名是从 XML 源文件生成的，因此是大写和下划线。

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 从 Access 中运行时没有失败，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。

如有任何帮助，我们将不胜感激。

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。

列名需要用方括号括起来。尽管与其他表一起工作并直接在 Access 中正常工作，但当通过 OleDbCommand 发送它时，一个(或多个)列名一定是导致问题的原因。

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)";
