您的过程的签名具有三个OUT参数。这些用于将值返回到调用程序。但是，过程的主体不会填充这些参数，而是使用DBMS_OUTPUT来显示它们。尽管如此，您仍然需要在调用代码中为这些参数分配目标变量。

让我们稍微更改一下代码：

CREATE OR REPLACE PROCEDURE STAT_STND_TERR_PRCDRE
(
   SPATIAL_QUERY_DATE_COND IN VARCHAR2,
   ITEM_LONGITUDE_NUM IN VARCHAR2,
   ITEM_LATITUDE_NUM IN VARCHAR2,
   STATE_ABBR OUT VARCHAR2,
   TERR_CD OUT VARCHAR2,
   TERR_NM OUT VARCHAR2
)
AS 
       v_state_abbr                   STAT_STND_TERR.STATE_ABBR%type;
       v_terr_cd                      STAT_STND_TERR.TERR_CD%type;
       v_terr_nm                      STAT_STND_TERR.TERR_NM%type;  
BEGIN
  SELECT T.STATE_ABBR AS STATE_ABBR, T.TERR_CD AS TERR_CD, T.TERR_NM AS TERR_NM 
  into v_state_abbr,v_terr_cd,v_terr_nm
  FROM STAT_STND_TERR T
  WHERE 
  T.STATE_ABBR='NY' AND 
  T.ORG_ABBR = 'iso' AND
  T.TERR_LINE_CD = 'pveh' AND
  TRUNC(T.TERR_EFF_DT) <= TO_DATE(SPATIAL_QUERY_DATE_COND,'YYYY-MM-DD') AND
  TRUNC(T.TERR_EXP_DT) > TO_DATE(SPATIAL_QUERY_DATE_COND,'YYYY-MM-DD') AND
  (SDO_RELATE(T.GEOM,
  MDSYS.SDO_GEOMETRY(2001, 8307,
  MDSYS.SDO_POINT_TYPE(ITEM_LONGITUDE_NUM,ITEM_LATITUDE_NUM,NULL),NULL,NULL),
  'MASK=ANYINTERACT QUERYTYPE=WINDOW')='TRUE') 
  AND ROWNUM = 1;

   -- populate the out parameters

    STATE_ABBR := v_state_abbr;
    TERR_CD := v_terr_cd;
    TERR_NM := v_terr_nm;
END;

现在我们用匿名块来称呼它：

declare 
   l_state_abbr                   STAT_STND_TERR.STATE_ABBR%type;
   l_terr_cd                      STAT_STND_TERR.TERR_CD%type;
   l_terr_nm                      STAT_STND_TERR.TERR_NM%type;
begin
STAT_STND_TERR_PRCDRE
(
   SPATIAL_QUERY_DATE_COND => '2019-06-01'
   ITEM_LONGITUDE_NUM => '12000',
   ITEM_LATITUDE_NUM => '38000',
   STATE_ABBR => l_state_abbr,
   TERR_CD => l_terr_cd,
   TERR_NM => l_terr_nm
);

    DBMS_OUTPUT.put_line ('STATE_ABBR:'|| l_state_abbr);
    DBMS_OUTPUT.put_line ('TERR_CD:'|| l_terr_cd);
    DBMS_OUTPUT.put_line ('TERR_NM:'|| l_terr_nm);
end;
/

因此，这里使用OUT参数的局部变量调用了该过程，并且调用程序显示了返回的值。
