QueryRequest

public QueryRequest()

Method Detail

getDefaultDataset

public DatasetReference getDefaultDataset()

[Optional] Specifies the default datasetId and projectId to assume for any unqualified table names in the query. If not set, all table names in the query string must be qualified in the format 'datasetId.tableId'.

Returns:

value or null for none

setDefaultDataset

public QueryRequest setDefaultDataset(DatasetReference defaultDataset)

[Optional] Specifies the default datasetId and projectId to assume for any unqualified table names in the query. If not set, all table names in the query string must be qualified in the format 'datasetId.tableId'.

Parameters:

defaultDataset - defaultDataset or null for none

getDryRun

public java.lang.Boolean getDryRun()

[Optional] If set to true, BigQuery doesn't run the job. Instead, if the query is valid, BigQuery returns statistics about the job such as how many bytes would be processed. If the query is invalid, an error returns. The default value is false.

Returns:

value or null for none

setDryRun

public QueryRequest setDryRun(java.lang.Boolean dryRun)

[Optional] If set to true, BigQuery doesn't run the job. Instead, if the query is valid, BigQuery returns statistics about the job such as how many bytes would be processed. If the query is invalid, an error returns. The default value is false.

Parameters:

dryRun - dryRun or null for none

getKind

public java.lang.String getKind()

The resource type of the request.

Returns:

value or null for none

setKind

public QueryRequest setKind(java.lang.String kind)

The resource type of the request.

Parameters:

kind - kind or null for none

getMaxResults

public java.lang.Long getMaxResults()

[Optional] The maximum number of rows of data to return per page of results. Setting this flag to a small value such as 1000 and then paging through results might improve reliability when the query result set is large. In addition to this limit, responses are also limited to 10 MB. By default, there is no maximum row count, and only the byte limit applies.

Returns:

value or null for none

setMaxResults

public QueryRequest setMaxResults(java.lang.Long maxResults)

[Optional] The maximum number of rows of data to return per page of results. Setting this flag to a small value such as 1000 and then paging through results might improve reliability when the query result set is large. In addition to this limit, responses are also limited to 10 MB. By default, there is no maximum row count, and only the byte limit applies.

Parameters:

maxResults - maxResults or null for none

getPreserveNulls

public java.lang.Boolean getPreserveNulls()

[Deprecated] This property is deprecated.

Returns:

value or null for none

setPreserveNulls

public QueryRequest setPreserveNulls(java.lang.Boolean preserveNulls)

[Deprecated] This property is deprecated.

Parameters:

preserveNulls - preserveNulls or null for none

getQuery

public java.lang.String getQuery()

[Required] A query string, following the BigQuery query syntax, of the query to execute. Example: "SELECT count(f1) FROM [myProjectId:myDatasetId.myTableId]".

Returns:

value or null for none

setQuery

public QueryRequest setQuery(java.lang.String query)

[Required] A query string, following the BigQuery query syntax, of the query to execute. Example: "SELECT count(f1) FROM [myProjectId:myDatasetId.myTableId]".

Parameters:

query - query or null for none

getTimeoutMs

public java.lang.Long getTimeoutMs()

[Optional] How long to wait for the query to complete, in milliseconds, before the request times out and returns. Note that this is only a timeout for the request, not the query. If the query takes longer to run than the timeout value, the call returns without any results and with the 'jobComplete' flag set to false. You can call GetQueryResults() to wait for the query to complete and read the results. The default value is 10000 milliseconds (10 seconds).

Returns:

value or null for none

setTimeoutMs

public QueryRequest setTimeoutMs(java.lang.Long timeoutMs)

[Optional] How long to wait for the query to complete, in milliseconds, before the request times out and returns. Note that this is only a timeout for the request, not the query. If the query takes longer to run than the timeout value, the call returns without any results and with the 'jobComplete' flag set to false. You can call GetQueryResults() to wait for the query to complete and read the results. The default value is 10000 milliseconds (10 seconds).

Parameters:

timeoutMs - timeoutMs or null for none

getUseQueryCache

public java.lang.Boolean getUseQueryCache()

[Optional] Whether to look for the result in the query cache. The query cache is a best-effort cache that will be flushed whenever tables in the query are modified. The default value is true.

Returns:

value or null for none

setUseQueryCache

public QueryRequest setUseQueryCache(java.lang.Boolean useQueryCache)

[Optional] Whether to look for the result in the query cache. The query cache is a best-effort cache that will be flushed whenever tables in the query are modified. The default value is true.

Parameters:

useQueryCache - useQueryCache or null for none

isUseQueryCache

public boolean isUseQueryCache()

Convenience method that returns only Boolean.TRUE or Boolean.FALSE.

Boolean properties can have four possible values: null, Data.NULL_BOOLEAN, Boolean.TRUE or Boolean.FALSE.

This method returns Boolean.TRUE if the default of the property is Boolean.TRUE and it is null or Data.NULL_BOOLEAN. Boolean.FALSE is returned if the default of the property is Boolean.FALSE and it is null or Data.NULL_BOOLEAN.

[ Optional] Whether to look for the result in the query cache. The query cache is a best-effort [ cache that will be flushed whenever tables in the query are modified. The default value is true.
