I have tables where a column is a longblob with images (png or gif).
When i try to change its data, some of them doesn't change.
I had always do this using SQLYog, but since version 10 it stop working.
The details:
I use a select with joins to show a partial view of attached tables. Then i select which table i wanna change, (those that contains the blob data). Then i change the image (clic on row / column, import from file, ok, ok). Finally, to make commit of changes i click on another row. If i view again the “changed” column, it had not change.
I'm not sure about this, but i think that for certains images the ok button doesn't make anything (because it doesn't alert me that something has change but not saved yet)
