MySQL 错误：1525。不正确的 DATETIME 值：''

Question

我的查询是-

SELECT ins.*, ic.* 
FROM insurance_data AS ins 
LEFT JOIN insurance_companies AS ic ON ins.provider = ic.id 
LEFT JOIN phone_numbers AS ph ON (ic.id = ph.foreign_id AND ph.type = 2) 
WHERE (ins.termination_date IS NULL OR ins.termination_date = "" OR 
       ins.termination_date = "0000-00-00") AND ins.provider IS NOT NULL 
 AND ins.provider > 0 
ORDER BY ins.date DESC LIMIT 1

我已经在 MySQL 中设置了 SQL 模式 更改为“ALLOW_INVALID_DATES、ONLY_FULL_GROUP_BY、ERROR_FOR_DIVISION_BY_ZERO、NO_ENGINE_SUBSTITUTION”。 但我仍然收到错误错误代码：1525。不正确的日期时间值：''。

我在 Windows 10 上使用 MySQL 版本 8.0.35。我正在 MySQL Workbench 中运行查询。

Answer 1

我修改了查询，删除了对

''

字段中空字符串 (

termination_date

) 的检查，仅关注

NULL

和大于

'0000-00-00'

的有效日期。希望这有助于修复错误>>

LEFT JOIN insurance_companies AS ic ON ins.provider = ic.id 
LEFT JOIN phone_numbers AS ph ON (ic.id = ph.foreign_id AND ph.type = 2) 
WHERE (ins.termination_date IS NULL OR ins.termination_date > '0000-00-00') 
  AND ins.provider IS NOT NULL 
  AND ins.provider > 0 
ORDER BY ins.date DESC 
LIMIT 1;
