How add BLOB type in Doctrine 2 using Symfony 2

由 跟風遠走 提交于 2019-11-28 13:09:07
In Symfony 2 I generate a Bundle for storing any type of document into database, but I need the BLOB column type. Tnx to this question I add the class BlobType into Doctrine DBAL, but for use the new column type I had to change Doctrine\DBAL\Types\Type [...] const BLOB = 'blob'; [...] private static $_typesMap = array( [...], self::BLOB => 'Doctrine\DBAL\Types\BlobType', ); Doctrine\DBAL\Platforms\MySqlPlatform (maybe it was better if I had changed Doctrine\DBAL\Platforms\AbstractPlatform) [...] protected function initializeDoctrineTypeMappings() { $this->doctrineTypeMapping = array( [...],

Java - SQLite Web Service Returning Blob

由 自闭症网瘾萝莉.ら 提交于 2019-11-28 13:08:11
I have a Java web service that is querying a SQLite database that contains blob data. I'm returning sql statements so that consumers of the service can just insert/update/delete with out processing the data. My problem is when I get to the blob data, the sqlite-jdbc driver says that the getBlob function is not implemented. So my question is this doable? Is there a better driver or way to accomplish this task? Thanks! SQLite supports BLOB datatype. Sqlitejdbc driver does not support the ResultSet#getBlob() method but BLOBs are supported. Just use ResultSet#getBytes() method. Here is the sample

Download large size files with angular file saver

由 前提是你 提交于 2019-11-28 12:46:37
I have implemented angular file saver into my project with purpose to download files and it works fine for small files, but for files larger then 50mb I see next error and downloading stops after 35-50mb. net::ERR_INCOMPLETE_CHUNKED_ENCODING I have tried to investigate this question in internet and have found that there is a limit 500mb on downloading because obviously cannot be stored so much information in RAM. Unfortunately I didn't find any other quite explanation how to resolve this issue, then I have asked the back-end guy and I've got the answer that everything is fine on his side. So

Oracle Database BLOB to InputStream in Java?

由 三世轮回 提交于 2019-11-28 12:43:44
I made a Java function that takes an InputStream as an input. I have a oracle.sql.BLOB instance to pass to that function. How can I convert it to a InputStream ? Do I need to re-write my function using a BLOB parameter, instead? Declare your Java parameter of type oracle.sql.BLOB as per the "Mapping Datatypes" documentation . Then, you call getBinaryStream() on that BLOB object to obtain your InputStream . You haven't really said how you're fetching data from the database, but you can use ResultSet.getBinaryStream() to get an InputStream , or call getBlob() to get a Blob , and then

oracle--导出、导入blob类型的字段

由 随声附和 提交于 2019-11-28 12:34:29
以下操作记录了blob字段的导出、导入方法流程 。 方法原理：利用UTL_FILE将blob字段的内容以二进制的形式导出到txt文档，然后用dbms_blob将文档内容导入到指定的数据库表中。 1、 创建一个文本文档来保存blob数据。 　　这里在E盘home/dhl下创建一个名为text.txt的文件。 2、 创建oracle临时目录 1 create or replace directory UTL_FILE_DIR as 'E:/home/dhl/'; 2 GRANT read ,write ON DIRECTORY UTL_FILE_DIR TO PUBLIC; 注意: 目录下面要有text.txt的文件 3、 导出blob数据 这里以SVS.SVS_ACCADM_SEALINFO表这张数据表为例子，其中的SEAL就是BLOB类型的字段 1 DECLARE 2 file_handle UTL_FILE.FILE_TYPE; 3 b_lob BLOB; 4 BEGIN 5 select SEAL into b_lob from SVS.SVS_ACCADM_SEALINFO where ID='100007922'; 6 7 file_handle := utl_file.fopen('UTL_FILE_DIR', 'test.txt', 'WB'); 8 utl_file

Basically, I'm trying to grab an image from a form post, then send that into a database MEDIUMBLOB field. Unfortunately, using my current method, the end result in the database column is always zero bytes. phpMyAdmin Screenshot Here is the code for the image upload on the form: input type="file" name="_imagePost"> Here is the PHP code on the page, I'm using MySQLi : if(isset($_POST['_imagePost'])

Chrome: Create file input from blob with Javascript?

由 人盡茶涼 提交于 2019-11-28 11:58:33
Well, the files attribute of an input[type=file] is read-only. Therefore I can not write my blob data into this input element. But if I create a new input file element using Javscript , then possible to insert blob data on creation? I am only interested in solutions working in chrome (extension) - other browsers do not matter. new File() constructor is available at chromium / chrome 38+. See File Constructor Sample , File API . var date = new Date(), filename = "file-" + date.getTime() + ".html"; var generatedFile = new File( ["<!DOCTYPE html><html><body>" + filename + "</body></html>"] ,
