withPreparedSqliteStatement Method
Use a prepared SQL statement, potentially from the statement cache. If the requested statement doesn't exist in the statement cache, a new statement is prepared. After the callback completes, the statement is reset and saved in the statement cache so it can be reused in the future. Use this method for SQL statements that will be reused often and are expensive to prepare. The statement cache holds the most recently used statements, discarding the oldest statements as it fills. For statements you don't intend to reuse, instead use withSqliteStatement.
