SQLSTATE[42000]：语法错误或访问冲突：1064 您的 SQL 语法有误；查看与您的 MariaDB 对应的手册

Question

我在 Laravel 8

中收到此错误

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '*)

这就是我尝试进行查询的方式

$totalCitasGenero = DB::table('citas')->selectRaw('idEspecialidad, genero,  count (*) as totalCitas')->join('personas', 'personas.id', '=', 'citas.idPersonaP')->groupBy('idEspecialidad','genero')->get();

这是我的表格的样子

CREATE TABLE `personas` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `nombre` varchar(50) NOT NULL,
  `apellido` varchar(50) NOT NULL,
  `cedula` varchar(10) NOT NULL,
  `email` varchar(40) DEFAULT NULL,
  `telefono` varchar(13) DEFAULT NULL,
  `direccion` varchar(100) NOT NULL,
  `ciudadResi` varchar(50) NOT NULL,
  `fechaNacimiento` date NOT NULL,
  `genero` varchar(100) NOT NULL,
  `estado` binary(1) NOT NULL,
  `idTipoPersona` int(11) NOT NULL,
  `idPersona` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `personas_FK` (`idTipoPersona`),
  KEY `personas_FK_1` (`idPersona`),
  CONSTRAINT `personas_FK` FOREIGN KEY (`idTipoPersona`) REFERENCES `tipo_personas` (`id`),
  CONSTRAINT `personas_FK_1` FOREIGN KEY (`idPersona`) REFERENCES `personas` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=73 DEFAULT CHARSET=utf8mb4

CREATE TABLE `citas` (
  `idPersonaD` int(11) NOT NULL,
  `idPersonaP` int(11) NOT NULL,
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `fecha` date NOT NULL,
  `hora` time NOT NULL,
  `idEspecialidad` int(11) NOT NULL,
  `estado` int(11) NOT NULL DEFAULT 1,
  PRIMARY KEY (`id`),
  KEY `citas_FK` (`idPersonaD`),
  KEY `citas_FK_1` (`idPersonaP`),
  KEY `citas_FK_2` (`idEspecialidad`),
  CONSTRAINT `citas_FK` FOREIGN KEY (`idPersonaD`) REFERENCES `personas` (`id`),
  CONSTRAINT `citas_FK_1` FOREIGN KEY (`idPersonaP`) REFERENCES `personas` (`id`),
  CONSTRAINT `citas_FK_2` FOREIGN KEY (`idEspecialidad`) REFERENCES `especialidades` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=88 DEFAULT CHARSET=utf8mb4

在 DBeaver 上查询工作正常，这就是它的样子

select idEspecialidad, genero,  count (*) as totalCitas 
from citas as c join personas
where c.idPersonaP = personas.id 
group by genero, idEspecialidad ;

我期待的结果就是下图中的结果。

将查询翻译成 Laravel 有什么问题？

如果我在将 ->get() 切换为 toSql() 之后对变量进行添加 -> 按照建议我得到了这个结果

"select idEspecialidad, genero,  count (*) as totalCitas from `citas` inner join `personas` on `personas`.`id` = `citas`.`idPersonaP` group by `idEspecialidad`, `genero`

我什至尝试再次将查询复制到 DBeaver 中，它工作正常，它只是在 Laravel 中不起作用，不知道为什么。

查询看起来不错，所以我不知道为什么在这种情况下它不起作用。

Answer 1

尝试删除 count (*)

中的白色 space

$totalCitasGenero = DB::table('citas')->selectRaw('idEspecialidad, genero,  count(*) as totalCitas')->join('personas', 'personas.id', '=', 'citas.idPersonaP')->groupBy('idEspecialidad','genero')->get();
