sql.Open() doesn't open anything
📰 Dev.to · Areesh Zafar
The sql.Open() function in Go doesn't actually open a database connection, but rather returns a database object that can be used to open connections later
Action Steps
- Use sql.Open() to get a database object
- Use the database object to open a connection with db.Conn() or db.Begin()
- Close the connection when finished to free up resources
- Check the database object's error status to handle any connection issues
