Creates a sql LIMIT statement if the sparql query needs one.

This method is needed because AdoDb does not support limits with prepared statements. It's a pity.

• return: SQL command to be appended to a query, to limit the number of result rows returned.
• access: public

• Query $query
• ADOConnection $dbConn

Determines the offset in the sqls, the position to start form.

• return: Array of two values: The first determines the index of the sql query to begin with, the second is the row offset that should be used in the final SQL query.
• access: public

• array $arSqls: Array of SQL query parts as returned by SparqlEngine_TypeSorter::getOrderifiedSqls()
