Qt 5.8 MySQL Input Medium Blob have diffrent size then Output

[Pablik]

One thing you could try and I suspect it would work, would be to base64 encode your data before you insert it and base64 decode it after you read it out the the database.

Good luck.

It's work, when i convert QByteArra::toBase64() the size is the same in QByteArra and in MySQL, but when i load from MySQL toBase64() how to convert to orginal QByteArra ??

OK i found QByteArra::fromBase64()

Everything work, thx for help
