【问题描述】：

我重写代码..并得到这个错误：

不兼容的数据类型组合[SQL State=42562, DB Errorcode=-5562]

MERGE INTO tj USING (VALUES (?) )
  AS vals (created_date) 
  ON vals.created_date  = tj.created_date
  WHEN MATCHED THEN UPDATE SET tj.created_date= vals.created_date
  WHEN NOT MATCHED THEN INSERT VALUES  vals.created_date

如何修复该代码？

【参考方案1】：

您需要将参数转换为 tj 的 created_date 列的类型。类型可以是 DATE 或 TIMESTAMP。

MERGE INTO tj USING (VALUES (CAST(? AS DATE)) )
AS vals (created_date) 
ON vals.created_date  = tj.created_date
WHEN MATCHED THEN UPDATE SET tj.created_date= vals.created_date
WHEN NOT MATCHED THEN INSERT VALUES  vals.created_date
