Использование конфигурации конфигурации командной строки BQ configuration.load.quote

Question

Я хочу знать, как использовать инструмент командной строки BQ. Я могу изменить конфигурацию задания BigQuery API. Например, я хочу изменить свойство configuration.load.quote из инструмента командной строки. Есть ли какой-то способ. Мне это нужно, чтобы загрузить таблицу с полем двойными кавычками (") внутри.

Answer 1

Вы не можете изменить работу, как только он будет создан, но я предполагаю, что вы хотите установить котировки свойство при создании задания.

в большинстве случаев, bq help <command> получите, что вам нужно. Вот вывод bq help load. Как вы можете видеть, вы просто должны указать --quote="'" после команды, но перед аргументами.

$ bq help load 
Python script for interacting with BigQuery. 


USAGE: bq.py [--global_flags] <command> [--command_flags] [args] 


load  Perform a load operation of source into destination_table. 

     Usage: 
     load <destination_table> <source> [<schema>] 

     The <destination_table> is the fully-qualified table name of table to 
     create, or append to if the table already exists. 

     The <source> argument can be a path to a single local file, or a 
     comma-separated list of URIs. 

     The <schema> argument should be either the name of a JSON file or a 
     text schema. This schema should be omitted if the table already has 
     one. 

     In the case that the schema is provided in text form, it should be a 
     comma-separated list of entries of the form name[:type], where type 
     will default to string if not specified. 

     In the case that <schema> is a filename, it should contain a single 
     array object, each entry of which should be an object with properties 
     'name', 'type', and (optionally) 'mode'. See the online documentation 
     for more detail: 
     https://developers.google.com/bigquery/preparing-data-for-bigquery 

     Note: the case of a single-entry schema with no type specified is 
     ambiguous; one can use name:string to force interpretation as a 
     text schema. 

     Examples: 
     bq load ds.new_tbl ./info.csv ./info_schema.json 
     bq load ds.new_tbl gs://mybucket/info.csv ./info_schema.json 
     bq load ds.small gs://mybucket/small.csv name:integer,value:string 
     bq load ds.small gs://mybucket/small.csv field1,field2,field3 

     Arguments: 
     destination_table: Destination table name. 
     source: Name of local file to import, or a comma-separated list of 
     URI paths to data to import. 
     schema: Either a text schema or JSON file, as above. 

     Flags for load:
