如题。
如果我不插入from字段，就没问题，就是将:
String sql_send= "insert into SMS(to,from,title,content,ptime) values( ' "+to+ " ', ' "+from+ " ', ' "+title+ " ', ' "+content+ " ', ' "+ptime+ " ') ";
改成:
String sql_send= "insert into SMS(to,title,content,ptime) values( ' "+to+ " ', ' "+title+ " ', ' "+content+ " ', ' "+ptime+ " ') ";
就OK
但一旦插from字段，就报错:
数据库更新出错:[Microsoft][ODBC Microsoft Access Driver] INSERT INTO 语句的语法错误。
究竟是怎么回事啊？究竟是我数据库设计错了还是其他问题啊？
大侠们快帮帮我啊，快愁死啦……
