ACCESS的System.Data.OleDb.OleDbException: INSERT INTO 语句的语法错误
一直用的是SQL 数据库，突然改用Access了，使用起来就是没有SQL 顺畅，老是出来些意想不到的错误。今天用Access做的网站程序进行添加数据，调试了一下午，总是异常……
提示ACCESS的System.Data.OleDb.OleDbException: INSERT INTO 语句的语法错误，刚才才在网络上找到了解决的方法，觉得有点不可思议~~在网络上看了看，也是学习ADO.net的人常犯的错误。所以写此日志，以提醒自己
/// <summary> /// 增加一条数据 /// </summary> public int Add(Model.article_comment model) { int newId; using (OleDbConnection conn = new OleDbConnection(DbHelperOleDb.connectionString)) { conn.Open(); using (OleDbTransaction trans = conn.BeginTransaction()) { try { StringBuilder strSql = new StringBuilder(); strSql.Append("insert into " + databaseprefix + "article_comment("); strSql.Append("channel_id,article_id,parent_id,user_id,user_name,user_ip,content,is_lock,add_time,is_reply,reply_content,reply_time,tel,zhengjian,zhengjianNum,workadd,address,youzhengbm,email,type,title,purpose,describe,newsway,getway)"); strSql.Append(" values ("); strSql.Append("@channel_id,@article_id,@parent_id,@user_id,@user_name,@user_ip,@content,@is_lock,@add_time,@is_reply,@reply_content,@reply_time,@tel,@zhengjian,@zhengjianNum,@workadd,@address,@youzhengbm,@email,@type,@title,@purpose,@describe,@newsway,@getway)"); OleDbParameter[] parameters = { new OleDbParameter("@channel_id", OleDbType.Integer,4), new OleDbParameter("@article_id", OleDbType.Integer,4), new OleDbParameter("@parent_id", OleDbType.Integer,4), new OleDbParameter("@user_id", OleDbType.Integer,4), new OleDbParameter("@user_name", OleDbType.VarChar,100), new OleDbParameter("@user_ip", OleDbType.VarChar,255), new OleDbParameter("@content", OleDbType.VarChar), new OleDbParameter("@is_lock", OleDbType.Integer,4), new OleDbParameter("@add_time", OleDbType.Date), new OleDbParameter("@is_reply", OleDbType.Integer,4), new OleDbParameter("@reply_content", OleDbType.VarChar), new OleDbParameter("@reply_time", OleDbType.Date), new OleDbParameter("@tel", OleDbType.VarChar,30), new OleDbParameter("@zhengjian", OleDbType.VarChar,30), new OleDbParameter("@zhengjianNum", OleDbType.VarChar,50), new OleDbParameter("@workadd", OleDbType.VarChar,30), new OleDbParameter("@address", OleDbType.VarChar,30), new OleDbParameter("@youzhengbm", OleDbType.VarChar,30), new OleDbParameter("@email", OleDbType.VarChar,30), new OleDbParameter("@type", OleDbType.VarChar,30), new OleDbParameter("@title", OleDbType.VarChar,50), new OleDbParameter("@purpose", OleDbType.VarChar,100), new OleDbParameter("@describe", OleDbType.VarChar,255), new OleDbParameter("@newsway", OleDbType.VarChar,30), new OleDbParameter("@getway", OleDbType.VarChar,30)}; parameters[0].Value = model.channel_id; parameters[1].Value = model.article_id; parameters[2].Value = model.parent_id; parameters[3].Value = model.user_id; parameters[4].Value = model.user_name; parameters[5].Value = model.user_ip; parameters[6].Value = model.content; parameters[7].Value = model.is_lock; parameters[8].Value = model.add_time; parameters[9].Value = model.is_reply; parameters[10].Value = model.reply_content; parameters[11].Value = model.reply_time; parameters[12].Value = model.tel; parameters[13].Value = model.zhengjian; parameters[14].Value = model.zhengjianNum; parameters[15].Value = model.workadd; parameters[16].Value = model.address; parameters[17].Value = model.youzhengbm; parameters[18].Value = model.email; parameters[19].Value = model.type; parameters[20].Value = model.title; parameters[21].Value = model.purpose; parameters[22].Value = model.describe; parameters[23].Value = model.newsway; parameters[24].Value = model.getway ; DbHelperOleDb.ExecuteSql(strSql.ToString(), parameters); //取得新插入的ID newId = GetMaxId(conn, trans); trans.Commit(); } catch { trans.Rollback(); return -1; } } } return newId; }
修改后的代码如下：

总结：在System.Data.oleDb 命名空间下使用SQL语句插入内容要在字段名与表名加“[]”
