Regaining Access: How to Resolve Locked SQLite Databases in Your Python Applications
import sqlite3
connection = sqlite3.connect("mydatabase.db")
cursor = connection.cursor()
cursor.execute("PRAGMA lock_status")
lock_status = cursor.fetchone()
print(f"Lock Status: {lock_status[0]}")
connection.close()
This code snippet uses the PRAGMA lock_status
command to retrieve the current lock status of the database.
Setting Lock Timeout (Python):
import sqlite3
connection = sqlite3.connect("mydatabase.db")
cursor = connection.cursor()
# Set timeout in milliseconds (example: 10 seconds)
cursor.execute("PRAGMA busy_timeout = 10000")
connection.commit()
connection.close()
This code snippet uses the PRAGMA busy_timeout
command to set a timeout value in milliseconds. If another process tries to acquire a lock but is busy for more than the specified timeout, the connection attempt will fail.

Identify and Terminate Locking Process:
Important Note:
- These methods can be less risk-free than restarting the application or closing open connections. There's a possibility of data inconsistencies if the database was actively being written to when locked.
- It's highly recommended to have a backup of the database before attempting any of these methods.
