clob轉化為string的orcal函式

create or replace function blob_to_clob (blob_in in blob) return clob

asv_clob    clob;

v_varchar varchar2(400000);

v_start pls_integer := 1;

v_buffer pls_integer := 400000;

tmp_num number;

begin

dbms_lob.createtemporary(v_clob, true);

tmp_num := ceil(dbms_lob.getlength(blob_in) / v_buffer);

if tmp_num > 0 then --防止傳入的blob為null或長度為0時引發錯誤

for i in 1..tmp_num

loop

v_varchar := utl_raw.cast_to_varchar2(dbms_lob.substr(blob_in, v_buffer, v_start));

v_start := v_start + v_buffer;

end loop;

end if;

return v_clob;

end blob_to_clob;
