问题 I have a table in Google BigQuery that I access and modify in Python using the pandas functions read_gbq and to_gbq . The problem is that appending 100,000 lines takes about 150 seconds while appending 1 line takes about 40 seconds. I would like to update a value in the table rather than append a line, is there a way to update a value in the table using python that is very fast, or faster than 40 seconds? 回答1: Not sure if you can do so using pandas but you sure can using google-cloud library.

问题 I want to select rows that sum up to a certain value. My SQL (SQL Fiddle): id user_id storage 1 1 1983349 2 1 42552 3 1 367225 4 1 1357899 37 1 9314493 It should calculate the sum up to 410000 and get the rows. Meanwhile it should get something like this: id user_id storage 2 1 42552 3 1 367225 As you can see, 42552 + 367225 = 409777. It selected two rows that are nearly 410000. I have tried everything but it didn't work :( Sorry for my language, I am German. 回答1: You can use a correlated

问题 If I have a table with an auto-incrementing ID column, I'd like to be able to insert a row into that table, and get the ID of the row I just created. I know that generally, StackOverflow questions need some sort of code that was attempted or research effort, but I'm not sure where to begin with Snowflake. I've dug through their documentation and I've found nothing for this. The best I could do so far is try result_scan() and last_query_id() , but these don't give me any relevant information

问题 I was reading relational algebra from one of the textbook. I came across DIVIDE operation. From Wikipedia: The division is a binary operation that is written as R ÷ S. The result consists of the restrictions of tuples in R to the attribute names unique to R, i.e., in the header of R but not in the header of S, for which it holds that all their combinations with tuples in S are present in R. Thus if R is: +----+----+ | A | B | +----+----+ | a1 | b1 | | a2 | b1 | | a3 | b1 | | a4 | b1 | | a1 |

问题 I have a project where users will need to fill out an Excel file and then export the data to an Access database. The data collected in the Excel file will need to be exported in 3 steps: (1) export data set 1 record, (2) query Access for the primary key (auto-number) of the newly imported record, (3) export data set 2 record, which includes the primary key populated as the foreign key. I am able to accomplish the first step by establishing and opening an ADODB connection. However, I am
