一、创建存储过程，可以直接使用

（1）通过sql developer 之间创建存储过程，直接复制粘贴即可

CREATE OR REPLACE PROCEDURE SQL_TO_CSV
(
 P_QUERY IN VARCHAR2, -- PLSQL文
 P_DIR IN VARCHAR2, -- 导出的文件放置目录
 P_FILENAME IN VARCHAR2 -- CSV名
 )
 IS
  L_OUTPUT UTL_FILE.FILE_TYPE;
  L_THECURSOR INTEGER DEFAULT DBMS_SQL.OPEN_CURSOR;
  L_COLUMNVALUE VARCHAR2(4000);
  L_STATUS INTEGER;
  L_COLCNT NUMBER := 0;
  L_SEPARATOR VARCHAR2(1);
  L_DESCTBL DBMS_SQL.DESC_TAB;
  P_MAX_LINESIZE NUMBER := 32000;
BEGIN
  --OPEN FILE
  L_OUTPUT := UTL_FILE.FOPEN(P_DIR, P_FILENAME, 'W', P_MAX_LINESIZE);
  --DEFINE DATE FORMAT
  EXECUTE IMMEDIATE 'ALTER SESSION SET NLS_DATE_FORMAT=''YYYY-MM-DD HH24:MI:SS''';
  --OPEN CURSOR
  DBMS_SQL.PARSE(L_THECURSOR, P_QUERY, DBMS_SQL.NATIVE);
  DBMS_SQL.DESCRIBE_COLUMNS(L_THECURSOR, L_COLCNT, L_DESCTBL);
  --DUMP TABLE COLUMN NAME
  FOR I IN 1 .. L_COLCNT LOOP
    UTL_FILE.PUT(L_OUTPUT,L_SEPARATOR || '"' || L_DESCTBL(I).COL_NAME || '"'); --输出表字段
    DBMS_SQL.DEFINE_COLUMN(L_THECURSOR, I, L_COLUMNVALUE, 4000);
    L_SEPARATOR := ',';
  END LOOP;
  UTL_FILE.NEW_LINE(L_OUTPUT); --输出表字段
  --EXECUTE THE QUERY STATEMENT
  L_STATUS := DBMS_SQL.EXECUTE(L_THECURSOR);
 
  --DUMP TABLE COLUMN VALUE
  WHILE (DBMS_SQL.FETCH_ROWS(L_THECURSOR) > 0) LOOP
    L_SEPARATOR := '';
    FOR I IN 1 .. L_COLCNT LOOP
      DBMS_SQL.COLUMN_VALUE(L_THECURSOR, I, L_COLUMNVALUE);
      UTL_FILE.PUT(L_OUTPUT,
                  L_SEPARATOR || '"' ||
                  TRIM(BOTH ' ' FROM REPLACE(L_COLUMNVALUE, '"', '""')) || '"');
      L_SEPARATOR := ',';
    END LOOP;
    UTL_FILE.NEW_LINE(L_OUTPUT);
  END LOOP;
  --CLOSE CURSOR
  DBMS_SQL.CLOSE_CURSOR(L_THECURSOR);
  --CLOSE FILE
  UTL_FILE.FCLOSE(L_OUTPUT);
EXCEPTION
  WHEN OTHERS THEN
    RAISE;
END;

（2）进行测试，执行sql

create or replace directory OUT_PATH as 'D:\';
EXEC sql_to_csv('select * from DSJ_ZXJC_ZBYQ_XY','OUT_PATH','ODS_MDS.DSJ_ZXJC_ZBYQ_XY.csv');

(3)测试成功后，即可进行对特有条件的筛选并进行导出

--SET serveroutput ON;
CREATE OR REPLACE directory OUT_PATH
AS
  'D:\anliku800';
  DECLARE
    CURSOR T_DT_GASINOIL_cursor
    IS
      --SELECT DISTINCT sbbm FROM T_DT_GASINOIL;
      SELECT DISTINCT sbbm
      FROM
        (SELECT tb.*
        FROM ggy.t_dt_gasinoil tb,
          (SELECT DISTINCT sbbm,
            COUNT(*)
          FROM ggy.t_dt_gasinoil t
          GROUP BY (sbbm)
          HAVING COUNT(*) > 800
          ) tmp
      WHERE tmp.sbbm=tb.sbbm
        );
    BEGIN
      FOR T_DT_record IN T_DT_GASINOIL_cursor
      LOOP
        --DBMS_OUTPUT.PUT_LINE(T_DT_record.sbbm);
        -- sql_to_csv('select * from T_DT_GASINOIL where sbbm =''||09M00120060005362||''','OUT_PATH','ODS_MDS.'||T_DT_record.sbbm||'.csv');
        sql_to_csv('select * from T_DT_GASINOIL where sbbm ='''||T_DT_record.sbbm||'''','OUT_PATH','ODS_MDS.'||T_DT_record.sbbm||'.csv');
      END LOOP;
    END; 

（1）注意点：进行存储过程函数拼接过程中，oracle的字符串拼接为||，（2）注意需要用到两次‘’ 时， 需要将 ‘’ 变成 ‘’’
