我在通过C#OleDbCommand向Access后端表运行插入查询时遇到问题。如果你复制它并直接在Access中运行它,SQL运行正常,并且在点击这个特定条目之前它适用于其他数据。
我尝试过改变数据,没有成功。这个源是一个XML文件。正确加载XML数据。
失败的命令是dbCommand.ExecuteNonQuery(),错误为“INSERT INTO语句中的语法错误”。
dbCommand = new OleDbCommand(string.Format(INSERT_RECURRING, tableName, fieldList, valueList), dbCon);
dbCommand.ExecuteNonQuery();
尝试运行和失败的SQL如下所示。请注意,表和字段名称是从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', '', '', '', '');
正如我前面提到的,这个SQL在Access中运行时没有失败,并且其他插入命令在此失败之前工作正常(在其他表上)。我删除了可能导致问题的所有SQL特殊字符。
非常感谢任何帮助。

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。尽管与其他表一起使用并且直接在Access中工作,但是当通过OleDbCommand发送它时,一个(或多个)列名称必然导致问题。
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)";
答案 1 :(得分:1)
使用parameters
代替字符串连接。
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();
}
