Inserting a file into Mysql (using delphi)

  • How can I insert a file (image, zip file, etc..) into mysql.

     
    • Is this not currently possible with Direct MySQL Objects?

       
    • you can use TFileStream (delphi) and use longblob fields in tables.

       
    • but using Direct SQL how do you do it?  All I see is a query method, but nothing that will allow me to use a stream.

       
    • try to save the stream to the string and then send this string as a value for some field in yours table. Works with txt 100% correctly. now i have some problems with mp3 file sending. I open mp3's like binary file into a string. I think, that the string from Filestream contains some symbols (like 'end of string' symbol)
      and thatway mysql report about some error in the string with this string.

    • This question seems to come back over and over again .. i will create a small sample tonight and will post it on sourceforge tomorrow.

      The binrary values needs to be escaped (see helpers unit), before sending it's value to the server.

      Kind regards,

    • Have a look at MysqlStreams in the 3rd party package. Demo project included.

    • The query is limited to 1 MB?
      I try with the demo of MysqlStreams and if I choose a picture with size < 1Mb it works fine, but if picture's size > 1 Mb, the query is not executed.
