Db2 如何在alter命令中在表中添加多列

我想借助ALTERQUERY在现有表中添加多列

ALTER TABLE users.UM_REG_HPTL_DET_DOC  
  ADD column HPTL_TADDRESS3 vargraphic(50),
  ADD column APPLICANT_ADDRESS3 varchar(50),
  ADD column APPLICANT_TADDRESS3(50),
  ADD column aadhar_no varchar(12),
  ADD column Registration_no varchar(50);

然后错误就来了

在“RESS3 vargraphic（50）”之后发现意外标记“”。预期的令牌可能包括：“”。。SQLCODE=-104，SQLSTATE=42601，DRIVER=4.18.60

ALTER TABLE users.UM_REG_HPTL_DET_DOC
  ADD column HPTL_TADDRESS3 vargraphic(50)
  ADD column APPLICANT_ADDRESS3 varchar(50)
  ADD column APPLICANT_TADDRESS3(50)
  ADD column aadhar_no varchar(12)
  ADD column Registration_no varchar(50);

移除“，”然后运行

ALTER TABLE users.UM_REG_HPTL_DET_DOC
  ADD column HPTL_TADDRESS3 vargraphic(50)
  ADD column APPLICANT_ADDRESS3 varchar(50)
  ADD column APPLICANT_TADDRESS3(50)
  ADD column aadhar_no varchar(12)
  ADD column Registration_no varchar(50);
