Class GetStatementResultResponse

    • Method Detail

      • hasColumnMetadata

        public final boolean hasColumnMetadata()
        For responses, this returns true if the service returned a value for the ColumnMetadata property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • columnMetadata

        public final List<ColumnMetadata> columnMetadata()

        The properties (metadata) of a column.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasColumnMetadata() method.

        Returns:
        The properties (metadata) of a column.

      • nextToken

        public final String nextToken()

        A value that indicates the starting point for the next set of response records in a subsequent request. If a value is returned in a response, you can retrieve the next set of records by providing this returned NextToken value in the next NextToken parameter and retrying the command. If the NextToken field is empty, all response records have been retrieved for the request.

        Returns:
        A value that indicates the starting point for the next set of response records in a subsequent request. If a value is returned in a response, you can retrieve the next set of records by providing this returned NextToken value in the next NextToken parameter and retrying the command. If the NextToken field is empty, all response records have been retrieved for the request.

      • hasRecords

        public final boolean hasRecords()
        For responses, this returns true if the service returned a value for the Records property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • records

        public final List<List<Field>> records()

        The results of the SQL statement.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasRecords() method.

        Returns:
        The results of the SQL statement.

      • totalNumRows

        public final Long totalNumRows()

        The total number of rows in the result set returned from a query. You can use this number to estimate the number of calls to the GetStatementResult operation needed to page through the results.

        Returns:
        The total number of rows in the result set returned from a query. You can use this number to estimate the number of calls to the GetStatementResult operation needed to page through the results.

      • toString

        public final String toString()
        Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
        Overrides:
        toString in class Object
