操作数类型冲突：datetime2与tinyint不兼容

Question

我无法用现有信息解决我的问题

Operand type clash: datetime2 is incompatible with tinyint

只有在使用mssql时才会出现此问题，希望有人已经知道此问题的解决方案

切换到mssql时出现了很多问题，它仍然只是其中之一，因为我设法解决了一些问题

@Entity
@Table
public class DoseAssignment {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@JsonProperty(access = JsonProperty.Access.READ_ONLY)
private Integer id;

@NotNull
@Size(min = 2, max = 30)
@Column(length = 30, nullable = false)
private String number;

@NotNull
@Column(columnDefinition = "tinyint", nullable = false)
private Integer unit;

@Temporal(TemporalType.DATE)
@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd", 
timezone = "UTC")
private Date date;

@NotNull
@Column(nullable = false)
@Temporal(TemporalType.DATE)
@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd",

@NotNull
@Column(nullable = false)

@Temporal(TemporalType.DATE)
@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd", 
timezone = "UTC")
private Date dateClose;

@ManyToOne(fetch = FetchType.LAZY)
@JsonProperty(access = JsonProperty.Access.WRITE_ONLY)

@ManyToOne(fetch = FetchType.LAZY)
@JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
private WorkMode workMode;

@ManyToOne(fetch = FetchType.LAZY)
@JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
private ProgramDangerous program;

@NotNull

Answer 1

datetime2类型的大小为6-8个字节（并包含日期的日期和时间部分）与一个1字节的tinyint，其值包含0-255。你不能将10磅的重量放入1盎司的容器中。

Answer 2

错误给出了答案。 tinyint和datetime2是不相容的。如果你想将tinyint转换为datetime2，你需要首先将它转换为datetime（与tinyint兼容），然后再转换为datetime2。
