SELECT DISTINCT ACL_ORDER TRA_CODE,
                ACL_STORE TRA_TOCODE,
                USR_DESC TRA_PERS,
                to_char(ACC.ACC_DATE, 'yyyy-mm-dd') TRA_DATE,
                COM.COM_DESC
  FROM ACCEPTLINES ACL,
       D7I_R5ORDERS ORD,
       ACCEPT ACC,
       D7I_R5COMPANIES COM,
       D7I_R5USERS
 WHERE TRA_DATE BETWEEN TO_DATE('2008-12-5', 'yyyy-mm-dd') AND
       TO_DATE('2009-1-5', 'yyyy-mm-dd')
   AND ACL.ACL_ORDER = ORD.ORD_CODE
   AND ACL_ISPASS = 'N'
   AND USR_CODE = ORD_BUYER
   AND ACC.ACC_ORDER = ACL.ACL_ORDER
   AND ORD.ORD_SUPPLIER = COM.COM_CODE

这条语句

SELECT DISTINCT ACL_ORDER TRA_CODE,ACL_STORE TRA_TOCODE, USR_DESC TRA_PERS,

这几句在这是什么意思？TRA_开头的是一个表的，ACL_开头的又是一个表的，USR_又是另外个表。
在这如果我要想加上时间查询的话，也就是 TRA_DATE BETWEEN TO_DATE('2008-12-5', 'yyyy-mm-dd') AND TO_DATE('2009-1-5', 'yyyy-mm-dd') AND....要加在哪呢？

SELECT DISTINCT ACL_ORDER TRA_CODE,ACL_STORE TRA_TOCODE, USR_DESC TRA_PERS,
这句是很奇怪！不敢妄加断言，等高手！

[xiaoxiao1984]

SELECT DISTINCT ACL_ORDER TRA_CODE,ACL_STORE TRA_TOCODE, USR_DESC TRA_PERS,...
表示查询ACL_ORDER TRA_CODE,ACL_STORE TRA_TOCODE, USR_DESC TRA_PERS,...这些字段组合后，都不重复的记录

LZ那写的都有问题. TRA_DATE那只是一个引用而已,都没有这个字段的定义,那要写ACC.ACC_DATE这个表的字段。
应该是:

SELECT DISTINCT ACL_ORDER TRA_CODE,
                ACL_STORE TRA_TOCODE,
                USR_DESC TRA_PERS,
                to_char(ACC.ACC_DATE, 'yyyy-mm-dd') TRA_DATE,
                COM.COM_DESC,ACC.ACC_DATE
  FROM ACCEPTLINES ACL,
       D7I_R5ORDERS ORD,
       ACCEPT ACC,
       D7I_R5COMPANIES COM,
       D7I_R5USERS
 WHERE ACC.ACC_DATE BETWEEN TO_DATE('2008-03-5', 'yyyy-mm-dd') AND
             TO_DATE('2009-11-5', 'yyyy-mm-dd')
         and ACL.ACL_ORDER = ORD.ORD_CODE
         AND ACL_ISPASS = 'N'
         AND USR_CODE = ORD_BUYER
         AND ACC.ACC_ORDER = ACL.ACL_ORDER
         AND ORD.ORD_SUPPLIER = COM.COM_CODE

TRA_开头的是表ACL_的别名
如:

select name 姓名, sex 性别, age 年龄 from Person

[dolphin0714]

也可以说TRA_是表ACL_的显示名
