Huh.
In the same vein as Viewing Content Of Blob In phpMyAdmin, i have a blob.
And just like in the screenshot of the given url, it says "blob". Thanks, phpmyadmin! You're the best!
Unlike the chap who asked the question above, though, I really want to edit the blob values, and then save them. So, if my blob has, as its text "ima blob yo" - and I can see that text, thanks to the solution given above - how do i edit that to "i am a blob, you".
I don't particularly want to upload a text file each time i edit a blob, that's totes bogue. Just want to edit it, as i would a text field.
cheers!
Ah. the phpmyadmin site, there this page: http://www.phpmyadmin.net/documentation/#faq1_31
$cfg['ProtectBinary'] boolean or string
Defines whether BLOB or BINARY columns are protected from editing when browsing a table's content. Valid values are:
* FALSE to allow editing of all columns;
* 'blob' to allow editing of all columns except BLOBS;
* 'all' to disallow editing of all BINARY or BLOB columns.
Ok, so that details how to allow me to edit my blobs.
I made the change
$cfg['ProtectBinary'] = FALSE;
$cfg['ShowBlob'] = TRUE;
and put these two as the last lines in my config.inc.php file, which, because i'm using UBUNTU and used the auto install sudo apt-get install phpmyadmin, was at /etc/phpmyadmin/
And everything worked, kinda. I can now edit my blobs... with the limitation that phpmyadmin shows the current contents of the blob in "blob-view", which is a whole bunch of numbers or some nonsense.
Simple solution i found was to:
write over the text. Simple editing isn't really an option, but luckily i didn't need to edit, just add in new data.
change the "function" option from ... i cannot remember what it was, but it was something crazy... to just "blank". That's the same kind of blank as the function option defaults for other values - ints etc
cheers,
andrew
PS that
$cfg['ShowBlob'] = TRUE;
was from the given url in the question i linked to. The poster states it isn't effective in phpmyadmin, but i only downloaded using a latest sudo-get a few months back, so it still works. Actually, i needed to put that value in to get editing to work.
I'm using phpMyAdmin v4.6.4. I find an option on GUI to set this config.
You can click on Home button. Then click on Panel Appearance settings.
In this screen, click on Main panel tab, then Edit mode tab.
After that, select 'no' in Protect binary columns dropdown.
Edit mode tab
If your BLOB field is really only text, then you might consider converting your BLOB field to a TEXT field (there should be no loss of data in the process). TEXT fields are viewable/editable directly from phpMyAdmin.

Using Apache Hop latest version I'm trying to read in a plain text file. This text file is old and basically only structured by its lines (it has no delimiter, no seperator, no enclosure, etc.). I would like to read and process the lines of this file as rows in my transformation.
I use the "Text file input" transformation to read the file. Apparently reading it works, but I seem have no field available when trying to retrieve the fields. It simply states that no fields were found.
When I run the "preview records" I do get empty records equal to the number if lines in the file, so that is good. However there is no data shown as there is no field detected.
Curiously enough, when I press "Show file content" I DO get the desired content, nicely structured in the rows as desired, so I know the file is being read correctly.
Does anyone know how to best read these kind of files?
PS: The files can be anywhere from 10 to 100000 lines.
When there is no header row with field names or Hop is not able to detect any fields you can also create a field in the fields tab and it will put content in there.
As we just use a position based approach and split the content using the specified delimiter everything should go in "field1" when no delimiter is found in the data.
Figured it out. The naming is a bit misleading, but you can use the "CSV File input" and then set a TAB as delimited. Then use preview on your file and you should find that the lines are actually being parsed.
I am writing a small website and I am at the last step, indeed my site allows a user to register then to connect, write text notes in a text area , save them in a database, this last step is : if I click on the button view my notes, I must have a page with a list of the saved notes, and if I click on a note in the list, the note appears in a text area , allowing me to modify it if I want and to save it again. I'm on nodejs and I looked for how to do this last step and I didn't find it. Ps : my table in the database have that form : textMemo|User .
you can use LONGTEXT datatype column. that can store 4GB data of characters.
I have this setup like in illustration attached, hope it clear enough. I load all xls files in loop from given folder.
While implementing new Derived Column box to record FileName from my loop I got truncation error. My variable initially was set to CCS.xls (Len=7, shortest name ).
I tried to increase Length in Derived Column Editor but failed to do this, as it's not active, I can't not type anything there, then I track that that original Length came from Variables value. In Variable windows I have DataType = String and no any option to set length.
So for now I made dummy empty file with looong CCS____1.xls name to avoid this problem and it works OK. But want to learn other good way to avoid this problem, looks like in this setup for data connection I need to use file with longest name (?)
You can change the Length property to 50 or larger manually in Advanced Editor.
Right-Click on the Derived column->Show Advanced Editor->Input and Output Properties->Derived Column Output->Output Columns->the new Column->Data Type Properties->Length
I downloaded this project:
http://vikku.info/programming/google-maps-v3/draggable-directions/saving-draggable-directions-saving-waypoints-google-directions-google-maps-v3.htm
To se how to save waypoints, I opened, the html, and tryied to save the waypoint, but it don't work, I dont know if i need to do something in SQL or not, I just tryied to make it works, please help me if you had sucess to make it works.
You have to:
create a DB with the name mapdir
create a table with the name mapdir inside this DB, the table should have only 1 field named value with the type text (there is a file mapdir.sql inside the ZIP-file, you may use it to create the table)
inside process.php you must edit line#5 and set the correct values for mysql_connect(servername,username,password)
You also should change process.php,Line#3 to
#$data = $_REQUEST['mapdata'];
....otherwise you later will not be able to load the waypoints when error_reporting is on.
But however, I wouldn't suggest to use this project like it is, there isn't any protection against SQL-injection.
For some reason while using PHPMyAdmin and attempting to save a table, even though I've entered all of the information I usually do I'm getting an alert box popping up with the content "Missing value in the form!".
Here's a screenshot of my PHPMyAdmin console (2 screens merged due to resolution):
PHPMyAdmin Create Table Modal Box
What I've tried so far:
Changing the data types all to VARCHAR with a length of 255 (except for the deindeal_id column, which remained INT with a length of 12).
Encasing description in "`" (bacticks), thinking it may be a reserved word of some sort.
Adding a coalition.
Using different table engines (InnoDB, MyISAM (the one I wanted)).
I'm really stumped as to what could be causing this issue, so any answers would be greatly appreciated!
Looks like a bug. Try going to Settings -> Features -> General tab and disable Ajax.
Then, try to create a new table and it won't use the popup.
I had this issue with the SQL form (where you can paste larger blocks of MySQL code). Not sure if it's a fluke, but I selected all of my input and then hit Go..and it worked.
Did you give it a table name.
I had the same problem & I simply forgot to give it a table name...at the top.
Got the same error, probably a Bug.
What Lex said: "Maybe if you define a column NOT NULL (ie. don't check the box in the Null column, you have to define a default value? – Lex 20 hours ago"
Nope. Doesn't work either and wouldn't make much sense. If you don't define a default value, the server will either insert an empty string, or fail the query; depending on settings.
I just encountered this....
It turns out I was forgetting to provide a name for the new table....
It's a bug I also "met" on phpMyAdmin v.3.5.1 - Disabling Ajax (and by default I love to disable it) will do the job.
Stop & start MySQL service. You can create table.
Yes It's a bug. what I did is to stop xampp (or if you're using wampp),
and then start them again. after that you will be able to create the table in phpMyAdmin
You can also try USE databasename; at the top of your query. In some versions this error seem to happen even if you did select your database, USE databasename; will fix this bug in those situations.
I just encountered this in 4.1.11. Seems to be a bug (again?). Disabling the popup and switching to the original theme resolved it somewhat for me, although you'll be without the popup which is a pain in the behind.
Switch back to Original theme:
Home > Theme: "Original"
Disable the popup:
Home > More settings > SQL queries > Disable: "Edit in window"
I got this problem too and I had opened same database in phpmyadmin in two separate tabs of browser . When I closed one tab and access phpmyadmin, the problem disappeared.
Just to let you know folks. Turning off my AdBlock Plus finally solved it for me. No more Missing value in the form! pop-ups when trying to submit something. Whitelist phpMyAdmin domain in any style or script altering add-on you might use.
