关于关联查询子查询（一个参数通过从另一个表中获得）

    

通过用户的id， user_id查询渠道表。 渠道表没有这个字段，要通过user_id去别的表查询得到渠道编号。

		SELECT
		
		FROM RECONCAV.T_CBS_RECON_CHANNEL
		
			
			 CHANNEL_ID in (select CHANNEL_ID from RECONCAV.T_CBS_R_ROLE_CHANNEL where role_id in (select role_id from RECONCAV.T_CBS_R_USER_ROLE where user_id = #{userId})) 
			
			 AND CHANNEL_ID = #{channelId} 
			 AND CHANNEL_NO = #{channelNo}
			 AND CHANNEL_NAME = #{channelName}
			 AND CHANNEL_NAME like '%'||#{channelNameLike}||'%'
			 AND REAL_CHANNEL_NO = #{realChannelNo}
			 AND REAL_CHANNEL_NAME = #{realChannelName}
			 AND RELATION_CHANNEL_NO = #{relationChannelNo}
			 AND REPORT_CHANNEL = #{reportChannel}
			 AND BANK_NO = #{bankNo}
			 AND ISSUE_BANK_ID = #{issueBankId}
			 AND BANK_NAME = #{bankName}
			 AND BANK_ACCT = #{bankAcct}
			 AND PRODUCT_NO = #{productNo}
			 AND CARD_INTERCEPT_TYPE = #{cardInterceptType}
			 AND FEE_SETTLE_CYCLE = #{feeSettleCycle}
			 AND REVERSE_DESC = #{reverseDesc}
			 AND SUBJECT_NO = #{subjectNo}
			 AND SETTLE_MODEL = #{settleModel}
			 AND VALIDITY_FLAG = #{validityFlag}
			 AND COST_SETTLEMENT_TYPE = #{costSettlementType}
			 AND CRT_TIME >= #{beginCrtTime}
			 AND CRT_TIME <= #{endCrtTime}
			
				and CHANNEL_NO in 
				
					#{dto}
				
			
		
		ORDER BY ${page.orderField} 
		${page.orderDirection}
	

 

2）子查询：根据bankorder_id修改， 而bankoeder_id在一个条件的范围内

		update RECONCAV.T_CBS_RECON_BANKORDER_CPS t set
		t.RECON_STATUS=#{reconStatus},t.HANDLE_STATUS=#{handleStatus} ,
		t.BILLORDER_ID = null,UPD_TIME = SYSDATE
		where
		t.BANKORDER_ID  in (
		    select tt.BANKORDER_ID  from  RECONCAV.T_CBS_RECON_BILLORDER_CPS tt
		    
			 tt.SYS_TRANS_TYPE = #{transType} 
			and tt.RECON_DATE =to_date(#{reconDate},'yyyy-mm-dd')
			and tt.CHANNEL_NO = #{channelNo} 
			
			)
