Reasons for Corrupt SQLite Database – SQLite Database Recovery

SQLite is a relational database management system widely used these days. But unlike other databases management systems, it is not a database engine of client-server data. In fact, it is integrated into the final program. SQLite is widely supported by multiple browsers, operating systems, embedded systems and many other applications. If you want a program database and embedded open for local storage application code / client software, you should use SQLite.
Like other database programs, also creates a SQLite database file. Since it is an open source program does not use a specific file extension. Sometimes corruption can cause serious problems and put SQLite data at high risk. We all know that database files are very prone to corruption due to its large size and complex structure files. Like any other file, the SQLite file database is not immune to corruption. There are several reasons that cause corruption, and you need to know. If you know the most common reasons for corruption, you can take the right steps to avoid them.

    Although the file locking problem seems normal, but sometimes they can cause serious damage. SQLite uses the file locking system for the database file and the Write-Ahead Logging (WAL) file. The main function of the locking system is to coordinate access to files between simultaneous processes. Sometimes, two threads or processes can cause inconsistent changes to a file database without coordination.
    
The SQLite database file is actually an ordinary disk. This means that any process can easily open and overwrite with unwanted or unwanted changes to make characters. Any thread or bad process can cause appropriate action easily, even SQLite can not help in this situation.
    
If an error occurs in the memory of the drive or flash, this may damage the SQLite database. This can cause changes or changes to the contents of the file, and lead to corruption.
    
SQLite has many built-in protections that work against database corruption. But sometimes, many of these protections are disabled by the configuration options. This will result in file corruption in the SQLite database.
    
Almost all programs contain internal errors. The SQLite program database has some minor bugs that can cause damage.
Corruption makes the SQLite database inaccessible. In such a situation, you have three possibilities:

    Valid backup for database
    
Manual trick to repair the SQLite database
    
Professional recovery solution SQLite databases
If you have a valid backup, you can easily restore the SQLite database. But if you do not have backup, you should try to repair the SQLite database manually. If you are using the SQLite database of the browser, simply follow these simple steps:
Step 1: Start the search for SQLite DB on your system. Click the Run SQL tab to run the command verification database.
Step 2: Enter this command – PRAGMA INTEGRITY_CHECK and click the Play button.
Note: Because the database is corrupted, an error message appears.
Step 3: You should now try to export the database to an SQL file. Click the File tab at the top> Export> SQL Database File.
Step 4: In the Export SQL dialog box, select the objects you want to export. You can also set other options.
Step 5: You can start the process by clicking OK. Wait until the process is complete.
Step 6: After that, you can import the database back to the SQLite browser. Click the File tab at the top> Import> SQL database file.
Now you can check your database. It’s fine now. Or if the corruption is still there, you should use the professional recovery solution. There are many software providers on the market that offer recovery solutions with the free trial version. In general, the demo / trial version is used for free evaluation purposes. If you use the demo / test, you can see what could recover the corrupted file database before you can pay for the software.
