从配置单元加载的sas在19m前被截断为32767个字符
你好。我有一个脚本要从hivedb的表中读取。但是，其中一列包含的数据超过32767个字符（sas字符字数限制）。为此，我在网上做了一些研究，并注意到我可以通过使用pass-thru来克服它。不过，我的脚本是从配置单元表中读取数据并在一个数据步骤中进行转换。
包含超过32767个数据的列是“geometry”
这是我的密码：

proc sort data=ncpdm.ncp_dim_ba 
               (keep=region zone state_code state business_area_code business_area gis_ba)
           out=business_area nodupkeys;
by gis_ba business_area_code;
run;

data business_area;
  set business_area;
  by gis_ba business_area_code;
  if first.business_area_code;
run;

     work.excp_ncp_dim_ba_geo;
  length excp_code $50;
  length gis_ba dotpos $50 zone $2 state_code $5 /*geometry $1500*/
         region state business_area_code $30 business_area $50 xval yval 8;
  if _n_=1 then do;
     declare hash h(dataset:"business_area");
     h.definekey('gis_ba');
     h.definedata('region','zone','state_code','state','business_area_code','business_area');
     h.definedone();
     call missing(region,zone,state_code,state,business_area_code,business_area);

      dbsastype=(cgis_area='CHAR(50)' geometry='CHAR(32767)' cgis_label='CHAR(50)'));
  if cgis_area='0290 - Sg. Petani' then cgis_area = '6290 - SUNGAI PETANI';
  if cgis_label='PERLIS' then cgis_area = '2610 - PERLIS';
  gis_ba=upcase(cgis_area);

我该怎么解决这个问题？有解决办法吗？预期的结果是在[，]块中每个有1行记录
例如，
x=794533591
y=649756392元
（一行，以上数据中其他块相同）
试用@pinegulf文章后更新
嗨，我指的是你的导游。我尝试了在datastep中使用varchar进行处理的方法。我首先使用pass-thru将列拆分为3个独立的列。然后，使用datastep和varchar连接回并进一步转换。然而，它从来没有在我的脚本工作。这是我的剧本：

proc sql;
      connect to hadoop as mydb
         (server=XXXX
          database=<removed>
        );
            create table a as 
            select * from connection to mydb(
            select  cgis_area
            ,substr(geometry,1,30000) as geometry1
            ,substr(geometry,30001,60000) as geometry2
            ,substr(geometry,60001,90000) as geometry3
            from DIST_OPERATION_BND_GIS 
            );
      disconnect from mydb;
    quit;

proc sort data=ncpdm.ncp_dim_ba 
               (keep=region zone state_code state business_area_code business_area gis_ba)
           out=business_area nodupkeys;
by gis_ba business_area_code;
run;

data business_area;
  set business_area;
  by gis_ba business_area_code;
  if first.business_area_code;
run;

data ncp_dim_ba_geo (drop=excp_code cgis_area)
     work.excp_ncp_dim_ba_geo;
  length excp_code $50;
  length gis_ba dotpos $50 zone $2 state_code $5
         region state business_area_code $30 business_area $50 xval yval 8;
  if _n_=1 then do;
     declare hash h(dataset:"business_area");
     h.definekey('gis_ba');
     h.definedata('region','zone','state_code','state','business_area_code','business_area');
     h.definedone();
     call missing(region,zone,state_code,state,business_area_code,business_area);
  end;
  set a;
    array geo {3} geometry1-geometry3;

**CREATE AND POPULATE VARCHAR FIELD**;

    length longgeo varchar(160000);
    do i = 1 to 3;
    longgeo = cat(longgeo,geo(i));
    end;
/*  set hpsncp.DIST_OPERATION_BND_GIS (keep=cgis_area geometry cgis_label*/
/*      dbsastype=(cgis_area='CHAR(50)' geometry='CHAR(32767)' cgis_label='CHAR(50)'));*/
  if cgis_area='0290 - Sg. Petani' then cgis_area = '6290 - SUNGAI PETANI';
  if cgis_label='PERLIS' then cgis_area = '2610 - PERLIS';
  gis_ba=upcase(cgis_area);
  rc2=h.find();
  if (rc2 ne 0) then do;
     excp_code='Exception: Unable to map business area';
     output work.excp_ncp_dim_ba_geo;
  end;
  if (rc2=0);
  longgeo=substr(longgeo,15);
  seq=1;
  do until(dotpos eq '');
     dotpos=compress(scan(longgeo, seq, '[]'),',','nk');
     if dotpos not in ('' '{' '}' '[' ']' ',') then do;
        xval=input(put(scan(dotpos,1,','),20.),20.)/1000;
        yval=input(put(scan(dotpos,2,','),20.),20.)/1000;
        if xval ne . and yval ne . then do;
           output ncp_dim_ba_geo;
        end;
     end;
     seq+1;
  end;
  keep excp_code cgis_area region zone state_code state business_area_code business_area seq xval yval;
run;

表ncp\u dim\u ba\u geo现在不产生任何结果。我做错了什么？
