从 BigQuery 表中获取计划数据到另一个 BigQuery 表（计划查询）

Question

I am really new to GCP and I am trying to Query in a GCP BigQuery to fetch all data from one BigQuery table and Insert all into another BigQuery table

I am trying the Following query where Project 1 & Dataset.Table1 is the Project where I am trying to read the data. and Project 2 and Dataset2.Table2 is the Table where I am trying to Insert all the data with the same Naming

SELECT * FROM `Project1.DataSet1.Table1` LIMIT 1000
insert  INTO `Project2.Dataset2.Table2`

But am I receiving a query error message?

Does anyone know how to solve this issue?

Answer 1

There may be a couple of comments...

1. The syntax might be different => insert into table select and so on - see DML statements in the standard SQL

2. Such approach of data coping might not be very optimal considering time and cost. It might be better to use bq cp -f... commands - see BigQuery Copy — How to copy data efficiently between BigQuery environments and bq command-line tool reference - if that is possible in your case.

Answer 2

The correct syntax of the query is as suggested by @al-dann. I will try to explain further with a sample query as below:

Query :

insert into `Project2.Dataset2.Table2`
select * from `Project1.DataSet1.Table1`

Input Table :

This will insert values into the second table as below:

Output Table :
