MQ2SQLite

This plugin allows you to interact with a SQLite database. A SQLite database is just a file that can be accessed using SQL commands. This plugin gives you access to the SQLite API and adds a TLO for viewing the results.

Since the results of the query are stored in memory, this can take up a lot of memory if you use unique query names and do not clear your results from memory. So, don't do that. Be sure to use the /sqlite clear <ResultName> function when you're done accessing the results. Otherwise you can use the same name for your query each time which will clear the results for you before each run.


Simple Usage

/sqlite query <"Path to Database File"> <QueryName> QUERY
Example:
/sqlite query C:\Test.db myquery SELECT * FROM Table;

Advanced Usage

By default, the /sqlite query command will open a database, run the query and then close the database. This doesn't allow for more complex operations like transactions or in-memory databases since the connection closes after every operation. It does have the benefit of handling all of the operations for you, however.

When your needs are a bit more robust, you can use the advanced query syntax to perform any operation you would like. This also allows for passing flags to the database open operation.

Opening a database connection:
/sqlite open <ConnectionName> <"Path to Database File"> [FLAGS]
Example:
/sqlite open MyDatabase C:\Test.db SQLITE_OPEN_READWRITE|SQLITE_OPEN_WAL

This would open the database C:\Test.db in read write mode with write ahead logging enabled. If no flags are passed then the default flags of SQLITE_OPEN_READWRITE | SQLITE_OPEN_CREATE are used. For a list of available flags see: https://www.sqlite.org/c3ref/c_open_autoproxy.html

Once the connection is open, you can use advquery to query that specific connection:
/sqlite advquery <ConnName> <ResultName> <QUERY>
Example:
/sqlite advquery MyDatabase myquery SELECT * FROM Table;

This performs the query on the connection named MyDatabase and stores the result in myquery. See above for how to access this result.


Finally, when you are done, you will want to close the connection to the database:
/sqlite close <ConnName>
Example:
/sqlite close MyDatabase

It should go without saying that advanced usage can be dangerous and I leave it in your hands not to screw it up. But, in case it doesn't go without saying: Advanced usage can be dangerous and I leave it in your hands not to screw it up.

You now have the full power of SQLite at your disposal. Use it wisely. Or don't. I'm not your dad.
