GBQ立即将结果保存到表中

Question

嗨，我正试图将此查询的结果与GBQ上的表相同。我已经链接了前面的问题以供参考

GBQ批量转换数据类型

启动代码

execute immediate (select '''
select `Group`, ''' || (select string_agg('cast(' || Fruit || ' as Numeric) as ' || Fruit ) from (
select regexp_extract_all(to_json_string((select as struct * except(`Group`) from unnest([t]))), r'"([^"]+)":') Fruits
from `project.dataset.table` t limit 1), unnest(Fruits) Fruit)  ||   
''' from `project.dataset.table`'''); 

的各种尝试

Create or Replace Table1 as
execute immediate (select '''
select `Group`, ''' || (select string_agg('cast(' || Fruit || ' as Numeric) as ' || Fruit ) from (
select regexp_extract_all(to_json_string((select as struct * except(`Group`) from unnest([t]))), r'"([^"]+)":') Fruits
from `project.dataset.table` t limit 1), unnest(Fruits) Fruit)  ||   
''' from `project.dataset.table`''');

execute immediate (select '''
select `Group`, ''' || (select string_agg('cast(' || Fruit || ' as Numeric) as ' || Fruit ) 
INTO Table1
from (
select regexp_extract_all(to_json_string((select as struct * except(`Group`) from unnest([t]))), r'"([^"]+)":') Fruits
from `project.dataset.table` t limit 1), unnest(Fruits) Fruit)  ||   
''' from `project.dataset.table`''');

Answer 1

使用以下方法

execute immediate (select '''create or replace table `project.dataset.table2` as 
select `Group`, ''' || (select string_agg('cast(' || Fruit || ' as float64) as ' || Fruit ) from (
select regexp_extract_all(to_json_string((select as struct * except(`Group`) from unnest([t]))), r'"([^"]+)":') Fruits
from `project.dataset.table` t limit 1), unnest(Fruits) Fruit)  ||   
''' from `project.dataset.table`''');
