   @code
   String datasetName = "my_dataset_name";
   String tableName = "my_table_name";
   TableId tableIdObject = TableId.of(datasetName, tableName);
   // This example reads the result 100 rows per RPC call. If there's no need
   // to limit the number,
   // simply omit the option.
   TableResult tableData = bigquery.listTableData(tableIdObject, TableDataListOption.pageSize(100));
   for (FieldValueList row : tableData.iterateAll()) {
     // do something with the row
   }

     // do something with the job
   }
 }
 

Throws:
BigQueryException - upon failure






cancel
boolean cancel(String jobId)
Sends a job cancel request. This call will return immediately. The job status can then be
 checked using either getJob(JobId, JobOption...) or getJob(String,
 JobOption...)).

 
If the location of the job is not "US" or "EU", cancel(JobId) must be used instead.

 
Example of cancelling a job.

 
 {
   @code
   String jobName = "my_job_name";
   boolean success = bigquery.cancel(jobName);
   if (success) {
     // job was cancelled
   } else {
     // job was not found
   }
 }
 

Returns:
true if cancel was requested successfully, false if the job was not
     found
Throws:
BigQueryException - upon failure






cancel
boolean cancel(JobId jobId)
Sends a job cancel request. This call will return immediately. The job status can then be
 checked using either getJob(JobId, JobOption...) or getJob(String,
 JobOption...)).

 
If the location of the job is not "US" or "EU", the jobId must specify the job
 location.

 
Example of cancelling a job.

 
 {
   @code
   String jobName = "my_job_name";
   JobId jobId = JobId.of(jobName);
   boolean success = bigquery.cancel(jobId);
   if (success) {
     // job was cancelled
   } else {
     // job was not found
   }
 }
 

Returns:
true if cancel was requested successfully, false if the job was not
     found
Throws:
BigQueryException - upon failure






query
TableResult query(QueryJobConfiguration configuration,
                  BigQuery.JobOption... options)
           throws InterruptedException,
                  JobException
Runs the query associated with the request, using an internally-generated random JobId.

 
If the location of the job is not "US" or "EU", query(QueryJobConfiguration, JobId,
 JobOption...) must be used instead.

 
This method cannot be used in conjuction with QueryJobConfiguration.dryRun()
 queries. Since dry-run queries are not actually executed, there's no way to retrieve results.

 
Example of running a query.

 
 {
   @code
   // BigQuery bigquery = BigQueryOptions.getDefaultInstance().getService();
   String query = "SELECT corpus FROM `bigquery-public-data.samples.shakespeare` GROUP BY corpus;";
   QueryJobConfiguration queryConfig = QueryJobConfiguration.newBuilder(query).build();

   // Print the results.
   for (FieldValueList row : bigquery.query(queryConfig).iterateAll()) {
     for (FieldValue val : row) {
       System.out.printf("%s,", val.toString());
     }
     System.out.printf("\n");
   }
 }
 

Throws:
BigQueryException - upon failure
InterruptedException - if the current thread gets interrupted while waiting for the query
     to complete
JobException - if the job completes unsuccessfully






query
TableResult query(QueryJobConfiguration configuration,
                  JobId jobId,
                  BigQuery.JobOption... options)
           throws InterruptedException,
                  JobException
Runs the query associated with the request, using the given JobId.

 
If the location of the job is not "US" or "EU", the jobId must specify the job
 location.

 
This method cannot be used in conjuction with QueryJobConfiguration.dryRun()
 queries. Since dry-run queries are not actually executed, there's no way to retrieve results.

 
See query(QueryJobConfiguration, JobOption...) for examples on populating a QueryJobConfiguration.

Throws:
BigQueryException - upon failure
InterruptedException - if the current thread gets interrupted while waiting for the query
     to complete
JobException - if the job completes unsuccessfully

@InternalApi
QueryResponse getQueryResults(JobId jobId,
                                           BigQuery.QueryResultsOption... options)
Returns results of the query associated with the provided job.

 
Users are encouraged to use Job#getQueryResults(QueryResultsOption...) instead.





writer
TableDataWriteChannel writer(WriteChannelConfiguration writeChannelConfiguration)
Returns a channel to write data to be inserted into a BigQuery table. Data format and other
 options can be configured using the WriteChannelConfiguration parameter. If the job is
 not in "US" or "EU", writer(JobId, WriteChannelConfiguration) must be used instead.

 
Example of creating a channel with which to write to a table.

 
 {
   @code
   String datasetName = "my_dataset_name";
   String tableName = "my_table_name";
   String csvData = "StringValue1\nStringValue2\n";

   WriteChannelConfiguration writeChannelConfiguration = WriteChannelConfiguration.newBuilder(tableId)
       .setFormatOptions(FormatOptions.csv()).build();
   TableDataWriteChannel writer = bigquery.writer(writeChannelConfiguration);
   // Write data to writer
   try {
     writer.write(ByteBuffer.wrap(csvData.getBytes(Charsets.UTF_8)));
   } finally {
     writer.close();
   }
   // Get load job
   Job job = writer.getJob();
   job = job.waitFor();
   LoadStatistics stats = job.getStatistics();
   return stats.getOutputRows();
 }
 

 
Example of writing a local file to a table.

 
 {
   @code
   String datasetName = "my_dataset_name";
   String tableName = "my_table_name";
   Path csvPath = FileSystems.getDefault().getPath(".", "my-data.csv");

   WriteChannelConfiguration writeChannelConfiguration = WriteChannelConfiguration.newBuilder(tableId)
       .setFormatOptions(FormatOptions.csv()).build();
   // The location must be specified; other fields can be auto-detected.
   JobId jobId = JobId.newBuilder().setLocation(location).build();
   TableDataWriteChannel writer = bigquery.writer(jobId, writeChannelConfiguration);
   // Write data to writer
   try (OutputStream stream = Channels.newOutputStream(writer)) {
     Files.copy(csvPath, stream);
   }
   // Get load job
   Job job = writer.getJob();
   job = job.waitFor();
   LoadStatistics stats = job.getStatistics();

TableDataWriteChannel writer(JobId jobId,
                             WriteChannelConfiguration writeChannelConfiguration)
Returns a channel to write data to be inserted into a BigQuery table. Data format and other
 options can be configured using the WriteChannelConfiguration parameter. If the job is
 not in "US" or "EU", the jobId must contain the location of the job.

 
Example of creating a channel with which to write to a table.

 
 {
   @code
   String datasetName = "my_dataset_name";
   String tableName = "my_table_name";
   String csvData = "StringValue1\nStringValue2\n";
   String location = "us";
   TableId tableId = TableId.of(datasetName, tableName);

       .setFormatOptions(FormatOptions.csv()).build();
   // The location must be specified; other fields can be auto-detected.
   JobId jobId = JobId.newBuilder().setLocation(location).build();
   TableDataWriteChannel writer = bigquery.writer(jobId, writeChannelConfiguration);
   // Write data to writer
   try {
     writer.write(ByteBuffer.wrap(csvData.getBytes(Charsets.UTF_8)));
   } finally {
     writer.close();
