Available Methods

• execute: run a statement and return nothing back
• query: run a query an get all the rows back as Map<String, dynamic>
• singleQuery: run a query and get a single row back as Map<String, dynamic>
• mappedQuery: run a query and get back rows parsed using your provided fromJson function
• mappedSingleQuery: run a query and get a single row parsed using your provided fromJson function

Raw Queries

For all available methods, just add raw to the name to pass in a raw SQL string instead of a Statement.
