Public methods

usePrepared

abstract @NonNull R <R extends Object> usePrepared(
    @NonNull String sql,
    @NonNull Function1<@NonNull SQLiteStatement, @NonNull R> block
)

Prepares a new SQL statement and use it within the code block.

Using the given SQLiteStatement after block completes is prohibited. The statement will also be thread confined, attempting to use it from another thread is an error.

Using a statement locks the connection it belongs to, therefore try not to do long-running computations within the block.

Parameters
`@NonNull String sql`	The SQL statement to prepare
`@NonNull Function1<@NonNull SQLiteStatement, @NonNull R> block`	The code to use the statement

Extension functions
