sql - 在选择内连接中选择

Question

我尝试在选择上进行内部连接。我的选择语句如下

SELECT con.fpd_no, 
       con.contract_no, 
        cm.cust_name, 
       (select cm.cust_name, TRIM(cm.address) || ', ' ||  TRIM(cm.zipcode) || ', ' || TRIM(klm.kelurahan_desc) || ', ' || TRIM(kcm.kecamatan_desc) || ', ' || TRIM(kbm.kabupaten_desc) || ', ' || TRIM(prm.propinsi_desc)
        from customer_master cm
        inner join kelurahan_master klm on klm.kelurahan_id=cm.kelurahan_id
        inner join kecamatan_master kcm on kcm.kecamatan_id=klm.kecamatan_id
        inner join kabupaten_master kbm on kbm.kabupaten_id=kcm.kabupaten_id
        inner join propinsi_master prm on prm.propinsi_id=kbm.propinsi_id;) as address, 
        con.principal_amount
   FROM contract con
   JOIN customer_master cm ON cm.cust_no = con.cust_no
   WHERE con.deal_code = 'A005'
    AND con.fpd_date BETWEEN '01-01-2016' AND '31-01-2016'
    AND con.fpd_no = '0103006116'
    AND con.objt_group = 'MOTOR';

但我收到此错误：

ORA-00911: 无效字符。

Answer 1

试试这个：

删除子选择上的分号并确保选择仅返回一行

SELECT con.fpd_no, con.contract_no, cm.cust_name, (select distinct cm.cust_name, TRIM(cm.address) || ', ' ||  TRIM(cm.zipcode) || ', ' || TRIM(klm.kelurahan_desc) || ', ' || TRIM(kcm.kecamatan_desc) || ', ' || TRIM(kbm.kabupaten_desc) || ', ' || TRIM(prm.propinsi_desc)
from customer_master cm
inner join kelurahan_master klm on klm.kelurahan_id=cm.kelurahan_id
inner join kecamatan_master kcm on kcm.kecamatan_id=klm.kecamatan_id
inner join kabupaten_master kbm on kbm.kabupaten_id=kcm.kabupaten_id
inner join propinsi_master prm on prm.propinsi_id=kbm.propinsi_id) as address, con.principal_amount
   FROM contract con
   JOIN customer_master cm ON cm.cust_no = con.cust_no
   WHERE con.deal_code = 'A005'
    AND con.fpd_date BETWEEN '01-01-2016' AND '31-01-2016'
    AND con.fpd_no = '0103006116'
    AND con.objt_group = 'MOTOR';
