Method Detail

cancel

void cancel()
     throws ConnectorException

Returns:

the time to wait in milliseconds

setQueryChunkSize

void setQueryChunkSize(int chunkSize)

Sets the maximum rows number in a RecordSet that is received as a return value of the retrieveResultSet() method. The result of an execution of a query is a record set. In order to be able to control the number of rows that are retrieved from the query result, set the chunk size to that number of rows, and use the next() method to move to the next chunk.

Parameters:

chunkSize - the number of rows for each record set chunk

retrieveQueryChunkSize

int retrieveQueryChunkSize()

Returns the maximum rows number in a RecordSet that is received as a return value of the retrieveResultSet() method.

Returns:

int the number of rows for each result set chunk
