问题 I am attempting to read a blob message and display it as a variable in one of my procedures, but am getting the error below: Error - ORA-22835: Buffer too small for CLOB to CHAR or BLOB to RAW conversion (actual: 9923, maximum: 2000) I have googled and found a suggestion to trim the blob message as below, but would rather display the complete blob message as a string. UTL_RAW.CAST_TO_VARCHAR2(dbms_lob.substr(variable_name,2000,1)) How can I display the complete message? Is there a setting on

Changing types during binary deserialization in C#

One of the solutions in our company consumes a 3rd party service. Communication is done through XML messaging. On our end, we generate classes to be used based on XML schemas that they provide us, and at some point we serialize some of those types into a binary blob in our database for later use. The problem comes in where that 3rd party company has changed one of the fields from a boolean to an integer type. Now when we try to deserialize the data that's already there we predictably get a type conversion exception (can't convert from boolean to integer). My question is - how do we go about

Determinate mime type from MySQL column

由 可紊 提交于 2019-11-30 23:18:40
I received an exported database from MSAccess (not my favorite) and I imported it to a MySQL table. There's a column named 'customerImage' and is a 'long BLOB' type with 'binary' as attribute. How can I determinate the Mime Type? I've tried different methods but all of them requires to be a file but data. If someone could help me with PHP code or MySQL command would be great. IF your host still uses php 5.2 and dont have access to the fileinfo functions you can test the files header signature (magic numbers) to determine mime type function mimetype($data) { //File signatures with their

How to specify null value in MS Access through the JDBC-ODBC bridge?

由 人盡茶涼 提交于 2019-11-30 22:49:04
I am not able to call setNull on PreparedStatement using MS Access (sun.jdbc.odbc.JdbcOdbcDriver) preparedStatement.setNull(index, sqltype). Is there a workaround for this? For LONGBINARY data type, I tried the following calls, neither worked. setNull(index, java.sql.Types.VARBINARY) setNull(index, java.sql.Types.BINARY) java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver]Invalid SQL data type at sun.jdbc.odbc.JdbcOdbc.createSQLException(JdbcOdbc.java:6957) at sun.jdbc.odbc.JdbcOdbc.standardError(JdbcOdbc.java:7114) at sun.jdbc.odbc.JdbcOdbc.SQLBindInParameterNull(JdbcOdbc.java:986

Postgresql, JDBC, and streaming BLOBs

由 久未见 提交于 2019-11-30 21:48:38
问题 I am trying to retrieve a blob from a postgres database using the jdbc drivers. It is too big to have in memory so I want to stream it as a download. I tried using the getBinaryStream method on ResultSet, but it turns out that this method actually reads it all into memory, so doesn't work for large file. Apparently, one can use the getBlob method on the resultset and the presumeably get the inputstream from the blob and go from there, but that is where I run into my problem. PreparedStatement

Physical location of FILESTREAM data

由 只谈情不闲聊 提交于 2019-11-30 19:47:48
问题 How could I know the physical location (so I can see it in Windows Explorer) path of a FILESTREAM data that I've just inserted into DB? 回答1: There is one option for this: method PhysicalPathName(). If you are on SQL Server 2012 or upper now, this code will work for you: SELECT stream.PhysicalPathName() AS 'Path' FROM Media OPTION (QUERYTRACEON 5556) For SQL Server 2008/2008 R2 you will need to enable trace flag 5556 for the whole instance: DBCC TRACEON (5556, -1) GO or for the particular
