Root Cause

Incorrect number of slashes in SQLite URL; four slashes indicate absolute path, three for relative path, but misplacement often occurs.

generic

中文

SQLite URL 中斜杠数量错误；四个斜杠表示绝对路径，三个表示相对路径，但常被误用。

Workarounds

  1. 100% success 
    engine = create_engine('sqlite:////tmp/test.db')  # absolute
# or
engine = create_engine('sqlite:///./test.db')  # relative

Dead Ends

Common approaches that don't work:

  1. 50% fail

    Changes path interpretation; may point to wrong file.

  2. 40% fail

    Makes it a relative path unexpectedly.
