Sql 无效属性的db2合并错误

我使用新创建的merge语句在db2中执行UPSERTS

我认为结构是正确的，但问题是我得到了错误

sqlstate[42000]语法或访问冲突：属性无效

我不确定问题到底在哪里，因为它不是很明确，但它似乎是来自我的一个价值观

合并：

MERGE INTO STATUS as S
    USING (VALUES(
                CAST(:ORDER as INT),
                CAST(:STATUS as VARCHAR),
                CAST(:IS_ACTIVE as DECIMAL(1,0)),
                CAST(:DATE_UPDATED as DATE)
                )
            )
    AS O(order, status, is_active, date_updated)    
    ON o.order = S.order_id 
WHEN MATCHED THEN UPDATE SET order_status = status, is_active = is_active, date_updated = date_updated
WHEN NOT MATCHED THEN INSERT VALUES(order, status, is_active, date_updated)

DB2foriSeries手册有以下示例

MERGE INTO employee AS t
   USING (VALUES(CAST(? AS CHAR(6)), CAST(? AS VARCHAR(12)),
                      CAST(? AS CHAR(1)), CAST(? AS VARCHAR(15)),
                      CAST(? AS SMALLINT), CAST(? AS INTEGER)))
          s (empno, firstnme, midinit, lastname, edlevel, salary)
   ON t.empno = s.empno
   WHEN MATCHED THEN
     UPDATE SET salary = s.salary
   WHEN NOT MATCHED THEN 
     INSERT (empno, firstnme, midinit, lastname, edlevel, salary)
            VALUES (s.empno, s.firstnme, s.midinit, s.lastname, s.edlevel,
                    s.salary)

也许您需要限定SET和final VALUES语句中的属性名称

例如，说is_active=is_active而不是is_active=O.is_active可能会让DB2感到困惑

什么应用程序类型运行此语句？我在php for DB2 7.2中运行此语句。在PowerShell中运行命令时，请尝试将参数显式转换为相应的数据类型。像值转换一样：顺序为int，…嗯，我已经做了，现在更新了我的答案，仍然得到了它。数据类型也与实际的列数据类型匹配我这样做了，但仍然有错误，但是，添加VARCHAR45而不是仅仅添加VARCHAR解决了它！谢谢你的帮助！
