加入游标

Question

我有以下pl sql proc，我正在尝试在CUR上加入表

FETCH CUR INTO V_CTR_ID,V_TRXN_INTRL_REF_ID,V_TRXN_DT,V_ACCT_INTRL_ID,V_TRXN_BASE_AM;
        EXIT WHEN CUR%NOTFOUND;
        --dbms_output.put_line('Enter CUR');
        OPEN CUR1 FOR  SELECT distinct CTR.OCCUPATION,CTR.TAX_ID
                         FROM
                            BR_CTR_TRANS BR join CUR on
                            CUR.V_TRXN_INTRL_REF_ID=BR.TRANS_REF_ID AND CUR.V_ACCT_INTRL_ID=BR.ACCT_IDENTIFIER AND CUR.V_TRXN_BASE_AM=BR.TRANS_AMT_BASE AND CUR.V_TRXN_DT=BR.TRANS_DT 
                            join CTR_XML_BR_COND CTR
                            on
                            BR.BR_CTR_SUM_REF_ID=CTR.CTR_ID;

我得到的错误是，CUR被视为表，并且给出的表或视图不存在。有人可以帮忙吗？

您不能将JOIN连接到游标，但是可以在后续的SQL语句中使用使用获取的值。在这种情况下，请删除“ join cur”，然后将on子句条件移至“ where”子句。

fetch cur into v_ctr_id,v_trxn_intrl_ref_id,v_trxn_dt,v_acct_intrl_id,v_trxn_base_am;
        exit when cur%notfound;
        --dbms_output.put_line('Enter CUR');
        open cur1 for  select distinct ctr.occupation,ctr.tax_id
                         from br_ctr_trans br 
                         join ctr_xml_br_cond ctr onbr.br_ctr_sum_ref_id=ctr.ctr_id
                        where 1=1
                          and cur.v_trxn_intrl_ref_id=br.trans_ref_id 
                          and cur.v_acct_intrl_id=br.acct_identifier 
                          and cur.v_trxn_base_am=br.trans_amt_base 
                          and cur.v_trxn_dt=br.trans_dt;
