运行此更新命令时遇到一些麻烦。我一直收到错误消息“ORA-00933：SQL命令未正确结束”。任何人都可以协助我帮助我做到这一点吗？这就是我现在所拥有的一切？

谢谢，乔治

Oracle不允许您加入更新声明。您需要使用相关子查询，例如：

UPDATE TABLE1 TOP_A
SET EARLIEST_STARTDATE = (
  SELECT CASE WHEN DATE_SUBMITTED <
      TO_DATE('01/04/' || EXTRACT(YEAR FROM ADD_MONTHS(DOB, 24)), 'DD/MM/YYYY')
    THEN TO_DATE('01/04/' || EXTRACT(YEAR FROM ADD_MONTHS(DOB, 24)),'DD/MM/YYYY')
    ELSE TO_DATE(DATE_SUBMITTED,'DD/MM/YY') END
  FROM TABLE1 SUB_A
  INNER JOIN TABLE2 SUB_C on SUB_A.ID = SUB_C.ID
  WHERE SUB_A.ID = TOP_A.ID
  AND ADD_MONTHS(SUB_C.DOB, 24) BETWEEN
    TO_DATE('01/01/' || EXTRACT(YEAR FROM ADD_MONTHS(SUB_C.DOB, 24)),'DD/MM/YYYY')
      AND TO_DATE('31/03/' || EXTRACT(YEAR FROM ADD_MONTHS(SUB_C.DOB, 24)),'DD/MM/YYYY')
)
WHERE EARLIEST_STARTDATE IS NULL
AND WS_ELIGIBILITY_STATUS = 1
AND (CLAIM_ADD_CRITERIA_FLAG = 'N' OR CAF = 'Y' OR (CCA_CODE = 'SC' AND CLAIM_ADD_CRITERIA_FLAG = 'Y'))
/

这假定TABLE_1.ID是唯一的。子查询执行两个表之间的连接，并且它与子查询中的WHERE SUB_A.ID = TOP_A.ID子句正在更新的行相关联。

您的AND / OR部分有点不清楚，因此您可能需要重新考虑这些子句的括号，以获得满足您业务需求的正确布尔结果。

其他情况下的TO_DATE(DATE_SUBMITTED,'DD/MM/YY')看起来也很可疑;如果DATE_SUBMITTED已经是日期，那么只需直接参考，不要为此致to_date()。在转换之前，您正在进行隐式转换为字符串;而且由于YY模型，你可能会在这个过程中失去这个世纪。

其他日期处理也可以简化。
