MySQL错误: Unknown column in 'field list' error

Question

大家好，我的 MySQL 有问题，我正在尝试将数据插入表中，但它返回此错误消息

Fatal error: SQL: SELECT e.idtarea AS 'idTarea', e.detalle AS 'detalle', e.precio AS 'precio', e.idOrdenReparacion AS 'idOrdenReparacion', e.fecha AS 'fecha', concat( 'Editar ', 'Eliminar' ) AS Opciones FROM Tarea e WHERE e.idtarea like '%%' ORDER BY e.idtarea;, Error: Unknown column 'e.fecha' in 'field list' in /opt/lampp/htdocs/scep/tareas.php on line 75

这是我的代码:

    $SQL="

      SELECT 
        e.idtarea AS 'idTarea', 
        e.detalle AS 'detalle', 
        e.precio AS 'precio', 
        e.idOrdenReparacion AS 'idOrdenReparacion', 
        e.fecha AS 'fecha', 
        concat('<a href=\'editarTarea.php?id=',e.idtarea,'\'>Editar</a>&nbsp;','<a href=\'eliminarTarea.php?id=',e.idtarea,'\' onclick=javascript:confirm(\'Eliminar?>\')>Eliminar </a>') AS Opciones 
      FROM Tarea e ".$FILTRAR_POR." 
      ORDER BY e.idtarea;";

      $RESULT = mysql_query($SQL) or trigger_error("SQL: $SQL, Error: " . mysql_error(), E_USER_ERROR); 

来自数据库的表 Tarea:

CREATE TABLE IF NOT EXISTS `Tarea` (
   `idTarea` int(11) NOT NULL AUTO_INCREMENT,
   `detalle` varchar(45) COLLATE latin1_danish_ci DEFAULT NULL,
   `precio` varchar(45) COLLATE latin1_danish_ci DEFAULT NULL,
   `idOrdenReparacion` int(11) NOT NULL DEFAULT '0',
   `fecha` date DEFAULT NULL,
   PRIMARY KEY (`idTarea`,`idOrdenReparacion`),
   KEY `fk_Tarea_OrdenReparacion1_idx` (`idOrdenReparacion`)
  ) ENGINE=InnoDB DEFAULT CHARSET=latin1 COLLATE=latin1_danish_ci AUTO_INCREMENT=2 ;

.....

  ALTER TABLE `Tarea`
  ADD CONSTRAINT `fk_Tarea_OrdenReparacion1` FOREIGN KEY (`idOrdenReparacion`) 
  REFERENCES `OrdenReparacion` (`idOrdenReparacion`) ON DELETE NO ACTION ON UPDATE NO ACTION;

您是否已验证该列不存在的情况下该表的先前版本不存在？如果该表已经存在一个版本，那么您的 SQL 将不会对表中的列进行更改。
