Answer 1

假设CLAIMNUMBER是数字数据类型，导致此问题的最可能原因是使用+作为连接运算符。而是使用||来连接字符串，您的查询应该可以正常工作。精炼查询应如下所示

select CASE
          WHEN CLAIMNUMBER = 311754 AND POLICY_NUMBER = 21620 THEN  cast(CLAIMNUMBER as varchar2(10))  'M'
          WHEN CLAIMNUMBER = 317802 AND POLICY_NUMBER = 15571 THEN  cast(CLAIMNUMBER as varchar2(10)) || 'M'
          WHEN CLAIMNUMBER = 318794 AND POLICY_NUMBER = 19325 THEN  cast(CLAIMNUMBER as varchar2(10)) || 'M'
          WHEN CLAIMNUMBER = 319510 AND POLICY_RECORD_ID = '21294_19' THEN cast(CLAIMNUMBER as varchar2(10)) || 'M'
          ELSE
                  cast(CLAIMNUMBER as varchar2(10))
        END AS CLAIMNUMBER1
