Fixing 'TimeoutExpired' Error When Connecting to SQL Server in Python
The 'TimeoutExpired' error when connecting to SQL Server in Python typically occurs when the connection attempt takes longer than the defined timeout period.
This could happen due to slow network conditions, server load, or inefficient queries.
To resolve this, try increasing the timeout duration in the connection string by adjusting the timeout parameter.
Additionally, ensure that your network connection to the server is stable, and check the SQL Server's performance.
If working with large queries, consider optimizing the SQL queries to ensure they execute within a reasonable time frame.
Another common solution is to use a connection pooler to manage database connections more efficiently.
Libraries like pyodbc or sqlalchemy in Python allow you to set a connection timeout, and you can also use try...except blocks to catch this error and handle it gracefully, retrying the connection if necessary.
