sql injection violation, syntax error: ERROR

Error querying database. Cause: java.sql.SQLException: sql injection violation, syntax error: ERROR. pos 998, line 14, column 41, token ON : select解决方法：关键字冲突

今天在改sql语句的时候遇到了这个问题，困扰了我许久，话不多说，看实例：

解析异常,e=查询异常,msg=数据查询失败，请检查sql语句是否准确  error : Error querying database.  Cause: java.sql.SQLException: sql injection violation, syntax error: ERROR. pos 998, line 14, column 41, token ON : selectb.UUID as "uuid",b.OPR_UUID as "oprUuid",b.SOURCE_ID as "sourceId",b.STS as "sts" ,g.ZS_SEQ_NO as "zsSeqNo",g.CREATE_TIME as "createTime",t.orsc_mno as "tranCorgNo",t.tran_dt as "tranDt",a.IN_MNO as "inMno",a.TRAN_ORG_DT as "tranOrgDt",a.ORDER_TYPE as "jftype",a.TRAN_ORG_UUID as "tranOrgUuid",a.TRAN_CRD_NO as "tranCrdNo",a.TRAN_ORG_AMT as "tranOrgAmt",g.AMT as "amt",b.AMT as "amt2",g.PROCESS_TYPE as "processType",b.DUTY_PARTY_TYP as "dutyPartyTyp",b.DUTY_PARTY_NO as "dutyPartyNo",b.DUTY_PARTY_NM as "dutyPartyNm",g.UPDATE_TIME as "updateTime",b.REMARK as "remark",if.MNO as "mno",a.SOURCE_TYPE as "sourceType"from DCM_OWNER.T_MBS_OPR_DTL  b left join DCM_OWNER.T_MBS_ZS_IF g on b.SOURCE_ID=g.UUIDleft join DCM_OWNER.t_mbs_bm_order_if a on g.bm_uuid=a.uuidleft join DCM_OWNER.t_pts_trandata t on t.uuid = a.source_idleft join DCM_OWNER.t_mbs_opr_if c on c.uuid=b.opr_uuidleft join DCM_OWNER.t_bap_mec_if if on if.in_mno=a.in_mnoWHERE (a.SOURCE_TYPE = '1' or a.SOURCE_TYPE = '3')

分析：报的是查询问题，我仔细检查了一下，把问题锁定在了上面第16行的left join DCM_OWNER.t_bap_mec_if if on if.in_mno=a.in_mno这句，发现表的别名用的是if，不觉恍然大悟，原来是和数据库的if关键字重复了，但奇怪的是为什么在数据库运行正常，而在程序中却报了错，我用的是mybatis，给表和字段起别名的时候都要注意，最好不用数据库中关键字和保留字作为别名。

可见养成良好的代码规范十分重要！！
