表中签到ID格式是以逗号分隔，需将ID拆开并分成多条数据

原有数据格式：

拆分后数据格式：

 

 拆分SQL:

select bc.资源名称,bc.资源ID,bc.签到时间,bc.签到人,bb.column_value 签到附件ID
    from report_fir.V_kw_checksign_info bc,table(hbrmw6.split_string(bc.签到附件ID,',')) bb;

HBRMW6.split_string函数创建：

CREATE OR REPLACE FUNCTION HBRMW6.split_string(p_string IN VARCHAR2, p_delimiter IN VARCHAR2)
RETURN sys.odcivarchar2list
AS
  l_tablen   PLS_INTEGER;
  l_idx      PLS_INTEGER;
  l_start    PLS_INTEGER := 1;
  l_delimlen PLS_INTEGER := LENGTH(p_delimiter);
  l_result   sys.odcivarchar2list := sys.odcivarchar2list();
BEGIN
  IF p_string IS NULL OR p_delimiter IS NULL THEN
    RETURN l_result;
  END IF;

  l_tablen := REGEXP_COUNT(p_string, p_delimiter) + 1;

  FOR i IN 1..l_tablen LOOP
    l_idx := INSTR(p_string, p_delimiter, l_start);

    IF l_idx = 0 THEN
      l_result.EXTEND;
      l_result(l_result.COUNT) := SUBSTR(p_string, l_start);
      EXIT;
    END IF;

    l_result.EXTEND;
    l_result(l_result.COUNT) := SUBSTR(p_string, l_start, l_idx - l_start);

    l_start := l_idx + l_delimlen;
  END LOOP;

  RETURN l_result;
END;
