sas合并问题

shiyiming

各位前辈大家好，我在执行sas sql合并时一直出现问题，导致无法合并其讯息如下:
78   PROC SQL;
79   CREATE TABLE book3 AS
80   SELECT both.no, both.time, both.date, both.execution, both.buy, both.sell, both.p1, both.q1, both.p2, both.q2, both.p3,

80 ! both.p10, both.q10, both.p11, both.q11, book2.sn, book2.oq, book2.op, book2.type, book2.odate, book2.otime, book2.ep,
80 ! book2.eq, book2.edate, book2.etime, book2.bs, book2.or, book2.six, book2.bir
81   FROM both full join book on (both.no=book2.sn) and (both.date=book2.odate) and (both.time=book2.otime) ;

请问这是代表什么意思呢，该如何解决呢?    <!-- s:? --><img src="{SMILIES_PATH}/icon_confused.gif" alt=":?" title="Confused" /><!-- s:? -->  <!-- s:? --><img src="{SMILIES_PATH}/icon_confused.gif" alt=":?" title="Confused" /><!-- s:? -->

目前语法为

首先,错误信息说等号两边变量的类型不同
[quote:1yer6xvk]Expression using equals (=) has components that are of different data types.[/quote:1yer6xvk]
其次,找SQL语句,连接条件涉及both表和book2表的3个变量
[quote:1yer6xvk]FROM both full join book on (both.no=book2.sn) and ([color=#FF0000:1yer6xvk]both.date=book2.odate[/color:1yer6xvk]) and (both.time=book2.otime) ;[/quote:1yer6xvk]
再次,看这3变量是不是相同类型的.both来自a1101/b1101,data是numeric的,book2来自book,odate是character的
[quote:1yer6xvk]data a1101;
set ep1;
if no='1101'; [color=#FF0000:1yer6xvk]date= 20090518;[/color:1yer6xvk]
run;
data b1101;
set ep2;
if no='1101'; [color=#FF0000:1yer6xvk]date= 20090519;[/color:1yer6xvk]
run; [/quote:1yer6xvk]
[quote:1yer6xvk]data book;
infile 'e:\abc\333.txt' missover dlm=&quot;,&quot;;
input sn $ oq op type $ [color=#FF0000:1yer6xvk]odate $[/color:1yer6xvk] otime $ eq ep edate $ etime $ bs $ or $ six $ bir $;
run; [/quote:1yer6xvk]

谢谢高手的帮助，终于合并成功了，果然是格式的问题!!
