DROP VIEW not supported in build/sqlite

[carloslfu]

DROP VIEW statement is not supported by SQLite build. Here is an example:

DROP VIEW IF EXISTS view_name;

The error that appears is:

[SyntaxError]: Expected "#", "--", "/*", ":=", "=", "INDEX", "TABLE", or [ \t\n\r] but "V" found.

I'd like to help with this one as it looks very similar to #1694 and I could use what you did to solve it via #1695 @taozhi8833998. This seems like a good start for me since I'll be using this library a lot and would like to contribute to it. WDYT?

@carloslfu Thank you for participating. I will release an update today, so I resolved it by myself. Please review the PR codes to ensure alignment with your intended codes.
