无法转换价值＆＃39; 2017-01-26 11：47：54.000000＆＃39;从第14栏到TIMESTAMP

Question

注意：这不是重复问题。

我按照this教程将MSSQL数据库迁移到了Mysql数据库。

在表格date_in中有一个日期时间提交说main。因此，当我使用mysql查询选择date_in时，它可以正常工作，如下所示

SELECT DATE_IN FROM incoming_audit.main where DATE_IN is not null limit 0, 50000;

在Java中 - Spring-Hibernate当我尝试从main表中获取前25条记录时，它会给我以下错误

错误（不允许我粘贴无效字符，请参见下图）

Hibernate: select this_.ID as ID1_1_0_, this_.AVAILABLE as AVAILABL2_1_0_, this_.BATTERY as BATTERY3_1_0_, this_.BOX as BOX4_1_0_, this_.CAPS as CAPS5_1_0_, this_.COA_EDITION as COA_EDIT6_1_0_, this_.COA_VERSION as COA_VERS7_1_0_, this_.CPU as CPU8_1_0_, this_.CPU_CORES as CPU_CORE9_1_0_, this_.CPU_DATA_WIDTH as CPU_DAT10_1_0_, this_.CPUSPD as CPUSPD11_1_0_, this_.CUSTOMER_ASSET as CUSTOME12_1_0_, this_.CUSTOMER_ID as CUSTOME13_1_0_, this_.DATE_IN as DATE_IN14_1_0_, this_.DATE_INC as DATE_IN15_1_0_, this_.FORM_FACTOR as FORM_FA16_1_0_, this_.HDD_INC_SERIAL as HDD_INC17_1_0_, this_.HDD_MODEL as HDD_MOD18_1_0_, this_.HDD_SERIAL as HDD_SER19_1_0_, this_.HDD_SIZE as HDD_SIZ20_1_0_, this_.HDD_SMART as HDD_SMA21_1_0_, this_.INC_TECH as INC_TEC22_1_0_, this_.INT_SERIAL as INT_SER23_1_0_, this_.KILLDISK as KILLDIS24_1_0_, this_.LOCATION as LOCATIO25_1_0_, this_.LOT_ID as LOT_ID26_1_0_, this_.MANUFACTURER as MANUFAC27_1_0_, this_.MODEL as MODEL28_1_0_, this_.NOTES as NOTES29_1_0_, this_.PALETTE as PALETTE30_1_0_, this_.PLASTIC_CONDITION as PLASTIC31_1_0_, this_.POWER_ADAPTER as POWER_A32_1_0_, this_.PXE_TECH as PXE_TEC33_1_0_, this_.RAM_PER_SLOT as RAM_PER34_1_0_, this_.RAM_SLOTS as RAM_SLO35_1_0_, this_.SCREEN_CONDITION as SCREEN_36_1_0_, this_.SERIAL as SERIAL37_1_0_, this_.TOTAL_RAM as TOTAL_R38_1_0_, this_.WEBCAM as WEBCAM39_1_0_ from Main this_ limit ?

列映射

@Type(type = "timestamp")
@Column(name = "DATE_IN", nullable = true)
private Date dateIn;

如何删除无效字符？

更新

当我在查询下面运行时，我的代码运行完美

UPDATE incoming_audit.main SET DATE_IN=null WHERE DATE_IN is not null;

但是当我在运行上面的查询后运行以下查询时，再次出现无效字符异常

UPDATE incoming_audit.main SET DATE_IN=now() WHERE DATE_IN is null;

但这一次是不同的例外。

Answer 1

我遇到了类似的问题，对于正在寻找选项的人，

Caused by: java.sql.SQLException: Cannot convert value '2021-04-23 10:43:54.000000' from column 15 to TIMESTAMP.

此列的数据类型为 datetime(6)。数据是通过休眠添加的，当我尝试加载数据时出现此错误。

该列与上次修改时间戳相关。

@Column(
        name = "last_modified_time",
        nullable = false
)
@Temporal(TemporalType.TIMESTAMP)
private Date lastModifiedTime;

因为 timestamp 更适合这里，所以我使用了 timestamp 数据类型而不是 datetime(6)，这样无需任何其他修改即可解决问题。
