Do you randomly receive the error message of SQLite Error Code 11? And don’t know the way out. Then, just sit comfortably and go through this blog carefully. In this blog, I will discuss the reasons and methods that will help the users to deal with this error.

SQLite database files are vulnerable to corruption just like any other computer file. It is seen that whenever the SQLite Database has some problems in its database system, it immediately returns the error code. However, these errors can occur either by human mistakes or by some internal issues. Sometimes it may be important to view the source code of your website as well. These common issues can be:

• Due to the internal bugs in the SQLite program.
• If the SQLite database file is overwritten.
• Issues related to file locking.
• Inappropriate synchronization process, or failure.
• If the Storage media fail.

The SQLite Error 11 can arise if the database disk image is deformed or distorted and can result in database file corruption.

Let’s assume, if something goes out of track then immediately the API functions will return error codes that will assist the users to track down the cause behind the error during processing the data. Whenever the SQLite error 11 arises then the user will immediately get a message that simply states: fails to login.

Now, you have little idea related to the topic so let’s go through in the deep and find the reasons and their solutions so that one can fix SQLite error 11 malformed database schema.

SQLSTATE[HY000]: General error: 11 database disk image is malformed [Solved]

by Jilu Joseph | Aug 25, 2019

One of the best database engines for most low to medium traffic websites is SQLite. Many popular applications like Horde webmail, CakePHP, etc. make use of it.

However, the SQLite database users often face various errors leading to corruption. One such error is,

SQLSTATE[HY000]: General error: 11 database disk image is malformed.

At Bobcares, we often get requests from our customers to fix SQLite database corruption errors as part of our Server Management Services.

Today, this write-up describes how our Support Engineers fix SQLite database corruption errors.

What causes corruption in SQLite?

We’ll begin by checking on the major reasons that can corrupt the SQLite database.

SQLite allows simultaneous access from different applications. And, when there is heavy use of the SQLite database, then there are hefty chances for database corruption. Usually, this corruption occurs due to database bugs or even hardware failure.

Similarly, regular use of the SQLite database leads to a large amount of data. And, when the size increase over the well-defined limit, it ends up in error SQLite Database Disk Image Is Malformed.

How we fixed “General error: 11 database disk image is malformed“

From our experience in managing servers, we’ve seen that the reasons for database corruption may vary depending on the system settings. It relies much on the applications and OS used in the server.

Now, let’s see the topmost reason for these SQLite database corruption errors and how our Support Team solved these errors.

Recently, one of our customers had an error while trying to access their emails via webmail.

Here, the customer was using the Horde webmail panel.

On checking our Support Engineers found that horde.sqlite database was corrupt. And, this resulted in the error.

As the database was already corrupt, the easiest fix was to recreate it.

Therefore, we solved the error by removing the corrupted database file and recreated a new database using:

When the same error occurs on a server without a control panel, the fix differs. We export the schema and data of the SQLite database. Further, we a new database, import the schema and data.

This will export the database in SQL format.
Further, we add a new database, import the schema and data.

Finally, we update the statistics for the indexes in the databases.

That’s it. We now have a working SQLite database.

[Need assistance to fix SQLite database corruption errors? We’ll help you.]

Sqlite error 11 malformed database schema

Post by Thomas Lohrum » Thu Oct 22, 2015 11:47 am

this is the first crash corrupting my database for a long time. However, it is a bad one. Directly importing from the corrupted database will fail. Nor can it be opened to export it as XML.

Trying sqlite3 to rebuild (.dump & .read) it caused the following behaviour:

The notebook file «C. » was created by an older version of CintaNotes.
Do you want to upgrade it?

After upgrading i get the following error:

The notebook file «C. » was created by a older version of CintaNotes and cannot be upgraded.
Error message: SQLite error 1:
there is already another table or index with this name: NoteCache

I think this is a bug.

Any ideas how to fix the database (other than restoring a backup)?

With 3010 i get the error: «Notebook format version 3010 not yet supported».

With 2950 it runs fine.

Will you change something, so this manual handling can be avoided in the future?

Next i did an export of my restored and the re-created database. I wanted to diff, so i can track, whether data got lost or not. However, the export result is unordered, thus diffing is not possible.

Can you add an order by, so this will be possible?

Thanks for your help.

Re: database malformed sqlite error 11

Yes, the last database schema version is actually less than 3010, so it’s good that you tried 2950 as well.

Yes, the change is trivial. CN will treat user version 0 as equal to the last one.

I am experiencing a similar issue. Unfortunately it won’t fix by now !

It started yesterday with a «database malformed . 11» error everytime I tried to save a new note or a modified one (reading was ok, as well as editing a note, as long as I don’t save it). I couldn’t export anything either (error message).

Today I tried to repair it with sqlite3 (to which I am a beginner).
The first integrity check reported 2 pages never used, «on tree .. page . cell 0 : a bad ptr map entry key. » and a «wrong # of entries in index ix_Notes_Tags_tagid».
So I used sqlite3 to dump the whole database, and rebuilt it with the command line.

Just like Thomas, I had then to change the user_version to 2950 to overcome the «older version» error message.
But now that I can acess the database. new or modifed notes still won’t save ! I get the same original message «database malformed. 11».
Which is strange is that now an integrity_check on the rebuilt database returns «ok» though.
Any idea how to avoid restoring back to last week?

In this solution we define a function junta_csv that receives the name of the output file to generate and a list with the input files.Input files are .csv of a single column, with a front row header. The headings of each input file are taken to form the header of the output file.Input files can be different long. If a file is exhausted before the others, it proceeds as if a blank line is read.Regarding implementation, the list handles contains the input files (file object). When the file runs out, the position is replaced with None.The function any to check if any file is open. The function examines the list and returns True if there is at least one value other than None on the list.def junta_csv(salida, archivos):

I have Calibre 0.7.6 and am now getting the error in the subject line (full error later in this message). On Windows 7 linked to a Kindle 2.

I’m afraid I can’t say if this happened after 0.7.6 was installed or was later — not paying attention.

Copying books to a device no longer works.

I tried ‘Check database integrity’ and got the same error.

I can’t think of anything else to try and throw myself on your mercy!

Thanks

Но я ничего не менял в базе. Просто скопипастил файл.
Неужели нужна какая-то специальная миграция?
