我正在使用 Spring Boot 开发 JavaFX 应用程序，当我尝试从复杂的 SQLite 数据库表中列出记录时遇到标题异常。
之前我已经能够从另一个简单的表中进行选择，但在这种情况下，是一个具有多个外键的表：
这是创建表的脚本：
CREATE TABLE citas (
id_cita INTEGER PRIMARY KEY AUTOINCREMENT
NOT NULL,
dni_paciente TEXT (20) CONSTRAINT dni_paciente REFERENCES pacientes (dni_paciente) MATCH SIMPLE
NOT NULL,
dni_sanitario TEXT (20) NOT NULL
CONSTRAINT dni_sanitario REFERENCES sanitarios (dni_sanitario),
id_tratamiento INTEGER CONSTRAINT identificador_tratamiento REFERENCES tratamientos (id_tratamiento)
NOT NULL,
fecha DATE NOT NULL,
hora_inicio TIME NOT NULL,
hora_fin TIME NOT NULL,
observaciones TEXT (100),
paciente_dni VARCHAR,
sanitario_dni VARCHAR,
tratamiento_identificador INTEGER,
dni VARCHAR
);
CREATE TABLE pacientes (
dni_paciente TEXT (20) PRIMARY KEY
NOT NULL,
nombre TEXT (50),
apellidos TEXT (50),
direccion TEXT (100),
telefono TEXT (20),
adjunto BLOB,
dni INTEGER
);
CREATE TABLE sanitarios (
dni_sanitario TEXT (20) PRIMARY KEY,
nombre TEXT (50),
apellidos TEXT (50),
especialidad TEXT (50)
);
CREATE TABLE tratamientos (
id_tratamiento INTEGER PRIMARY KEY ASC AUTOINCREMENT,
nombre TEXT (50),
descripcion TEXT (100),
identificador INTEGER
);
这是我的 Java 实体：
@Entity
@Table(name = "citas")
public class Citas {
@Id
@Column(name = "identificador", nullable = false, unique = true)
private Integer identificador;
@OneToOne
@JoinColumn(name = "dni_paciente")
private Pacientes paciente;
@OneToOne
@JoinColumn(name = "dni_sanitario")
private Sanitarios sanitario;
@OneToOne
@JoinColumn(name = "id_tratamiento")
private Tratamientos tratamiento;
@Column(name = "fecha,", nullable = true, unique = false)
private LocalDate fecha;
@Column(name = "hora_inicio", nullable = true, unique = false)
private LocalTime horaDesde;
@Column(name = "hora_fin", nullable = true, unique = false)
private LocalTime horaHasta;
@Column(name = "observaciones,", length = 100, nullable = true, unique = false)
private String observaciones;
// GETTERS AND SETTERS
@Entity
@Table(name = "pacientes")
public class Pacientes {
@Id
@Column(name = "dni_paciente", length = 20, nullable = false, unique = true)
private String dniPaciente;
@Column(name = "nombre", length = 50, nullable = true, unique = false)
private String nombre;
@Column(name = "apellidos", length = 50, nullable = true, unique = false)
private String apellidos;
@Column(name = "direccion", length = 100, nullable = true, unique = false)
private String direccion;
@Column(name = "telefono", length = 20, nullable = true, unique = false)
private String telefono;
@Lob
private byte[] adjunto;
@OneToOne
@JoinColumn(name="dni")
private Citas citas;
// GETTERS AND SETTERS
@Entity
@Table(name = "sanitarios")
public class Sanitarios {
@Id
@Column(name = "dni_sanitario", length = 20, nullable = false, unique = true)
private String dniSanitario;
@Column(name = "nombre", length = 50, nullable = true, unique = false)
private String nombre;
@Column(name = "apellidos", length = 50, nullable = true, unique = false)
private String apellidos;
@Column(name = "especialidad", length = 50, nullable = true, unique = false)
private String especialidad;
@OneToOne
@JoinColumn(name="dni_sanitario")
private Citas citas;
// GETTERS AND SETTERS
@Entity
@Table(name = "tratamientos")
public class Tratamientos {
@Id
@Column(name = "id_tratamiento", nullable = false, unique = true)
private Integer idTratamiento;
@Column(name = "nombre", length = 50, nullable = true, unique = false)
private String nombre;
@Column(name = "descripcion", length = 100, nullable = true, unique = false)
private String descripcion;
@OneToOne
@JoinColumn(name="identificador")
private Citas citas;
// GETTERS AND SETTERS
这是我的 Spring 数据存储库：
public interface CitasRepository extends PagingAndSortingRepository<Citas, Integer>, JpaRepository<Citas, Integer> {
}
服务实现：
@Service()
public class CitasServiceImpl implements CitasService {
@Autowired
private CitasRepository citasRepository;
@Override
public List<Citas> listarCitas() {
return citasRepository.findAll();
}
}
我已经在记录器中激活了 SQL：
select
citas0_.identificador as identifi1_1_,
citas0_.fecha,
as fecha2_1_,
citas0_.hora_inicio as hora_ini3_1_,
citas0_.hora_fin as hora_fin4_1_,
citas0_.observaciones,
as observac5_1_,
citas0_.dni_paciente as dni_paci6_1_,
citas0_.dni_sanitario as dni_sani7_1_,
citas0_.id_tratamiento as id_trata8_1_
from
citas citas0_
Hibernate:
select
citas0_.identificador as identifi1_1_,
citas0_.fecha,
as fecha2_1_,
citas0_.hora_inicio as hora_ini3_1_,
citas0_.hora_fin as hora_fin4_1_,
citas0_.observaciones,
as observac5_1_,
citas0_.dni_paciente as dni_paci6_1_,
citas0_.dni_sanitario as dni_sani7_1_,
citas0_.id_tratamiento as id_trata8_1_
from
citas citas0_
Hibernate 正在创建错误的选择

答案 0 :(得分：0)
@Column(name = "observaciones,", length = 100, nullable = true, unique = false) 名称末尾有一个逗号，这对 SQL 造成严重破坏。去掉逗号！ fecha, 也一样。
