我正在我指定的目录中创建一个文件。我想为每次运行在不同文件名的目录中创建不同的文件夹名称。 这个文件夹应该压缩。
目前我正在使用:
create or replace
PROCEDURE xx_WriteBLOBToFILE (myfilename IN VARCHAR2,L_PERSON_ID IN NUMBER) IS
v_blob BLOB;
blob_length INTEGER;
out_file utl_file.file_type;
v_buffer RAW(32767);
chunk_size BINARY_INTEGER := 32767;
blob_position INTEGER := 1;
BEGIN
-- Retrieve the BLOB for reading
Select Image Into V_Blob From Per_Images
Where Parent_Id =L_PERSON_ID;
-- Retrieve the SIZE of the BLOB
blob_length:=DBMS_LOB.GETLENGTH(v_blob);
-- Open a handle to the location where you are going to write the BLOB to file
-- NOTE: The 'wb' parameter means "write in byte mode" and is only availabe
-- in the UTL_FILE package with Oracle 10g or later
out_file := UTL_FILE.FOPEN ('INTF_DIR1', myfilename, 'wb', chunk_size);
-- Write the BLOB to file in chunks
WHILE blob_position <= blob_length LOOP
IF blob_position + chunk_size - 1 > blob_length THEN
chunk_size := blob_length - blob_position + 1;
END IF;
DBMS_LOB.READ(v_blob, chunk_size, blob_position, v_buffer);
UTL_FILE.PUT_RAW(out_file, v_buffer, TRUE);
blob_position := blob_position + chunk_size;
END LOOP;
-- Close the file handle
UTL_FILE.FCLOSE (out_file);
END;
这段代码正在将blob图像移动到目录中的文件夹中。我想要在一个单独的文件夹中生成这个blob图像,该文件夹将位于压缩文件夹下
