BigQuery command line tool - append to table using query -

-

is possible append results of running query table using bq command line tool? can't see flags available specify this, , when run it fails , states "table exists"

bq query --allow_large_results --destination_table=project:dataset.table "select * [project:dataset.another_table]"

bigquery error in query operation: error processing job '': exists: table project:dataset.table

originally bigquery did not support standard sql idiom 

 insert foo select a,b,c bar d>0;

and had way --append_table

but according @will's answer, works now.

originally bq, there was

bq query --append_table ...

the bq query command 

$ bq query --help

and output shows append_table option in top 25% of output.

python script interacting bigquery.   usage: bq.py [--global_flags] <command> [--command_flags] [args]   query    execute query.           examples:          bq query 'select count(*) publicdata:samples.shakespeare'           usage:          query <sql_query>           flags query:  /home/paul/google-cloud-sdk/platform/bq/bq.py:   --[no]allow_large_results: enables larger destination table sizes.   --[no]append_table: when destination table specified, whether or not     append.     (default: 'false')   --[no]batch: whether run query in batch mode.     (default: 'false')   --destination_table: name of destination table query results.     (default: '') ...

instead of appending 2 tables together, might better off union all sql's version of concatenation.

in big query comma or , operation between 2 tables in select tablea, tableb union all, not join, or @ least last time looked.

-
i had following code works fine on localhost: $document = new domdocument(); $document->loadhtml($p_result); $form = $document->getelementsbytagname('form')->item(0); // code continues using $form variable after same code updated on outside server, loadhtml() failed , issued warning. warning: domdocument::loadhtml() expects parameter 1 valid path, string given in path/name/to/script.php returned null instead of object code pretty gets fatal error. note contents of $p_result absolutely same on outside server , on localhost. but why displays kind of warning , why not work? doesn't loadhtml() expects argument 1 string in first place? why method expects parameter 1 valid path ? just make clear i'm not calling loadhtmlfile() , i'm calling loadhtml() . thanks. you're affected one of php bugs . issue present in php 5.6.8 , 5.6.9. have affected php version on server, , bug-free version on localhost. the bug forbids null
