Example 2 with RowsResult

use of org.teiid.translator.google.api.result.RowsResult in project teiid by teiid.

the class GoogleDataProtocolAPI method executeQuery.

/**
 * Most important method that will issue query [1] to specific worksheet. The columns in the query
 * should be identified by their real alphabetic name (A, B, C...).
 *
 * There is one important restriction to query. It should not contain offset and limit clauses.
 * To achieve functionality of offset and limit please use corresponding parameters in this method.
 *
 * [1] https://developers.google.com/chart/interactive/docs/querylanguage
 *
 * @param query The query defined in [1]
 * @param batchSize How big portions of data should be returned by one roundtrip to Google.
 * @return Iterable RowsResult that will actually perform the roundtrips to Google for data
