You have a query that filters a BigQuery table using a WHERE clause on timestamp and ID columns. By using bq query -- -dry_run you learn that the query triggers a full scan of the table, even though the filter on timestamp and ID select a tiny fraction of the overall data a. Create a separate table for each ID. B Use the LIMIT keyword to reduce the number of rows returned. C Recreate the table with a partitioning column and clustering column. D Use the bq query - -maximum_bytes_billed flag to restrict the number of bytes billed.
I have this and it is not showing as correct: CREATE TRIGGER trg_updatecustbalance2 AFTER DELETE ON INV_MYSQL FOR EACH ROW UPDATE CUST_MYSQL SET CUST_BALANCE = CUST_BALANCE - OLD.INV_AMOUNT; DELETE FROM INV_MYSQL WHERE INV_NUM = 9006; SELECT * FROM INV_MYSQL; Here is the question: Write a trigger to update the CUST_BALANCE from CUST_MYSQL when an invoice is deleted from INV_MYSQL. Name the trigger trg_updatecustbalance2. (You should delete INV_NUM 9006 from INV_MYSQL to ensure your code is correct.)

Implement the following ER model and sample data using Oracle SQL Developer and your CDM Oracle database account. You will submit a SQL script file and its entire outputs. The table name should be CUSTOMERS (plural). Each CustomerID should be a 3-digit number. Names should be strings of up to thirty characters. The sample data should be: 101, John Doe 102, [Rachel Araya] Order The table name should be ORDERS (plural). Each OrderID should be a 4-digit number. Product names should be strings of up to thirty characters. The sample data should be: 1001, 01-JAN-22, Apple, 101 1002, [a date of your choice], [a product of your choice], 102 PLEASE FOLLOW BELOW The SQL script to (i) drop the two tables, (ii) create the two tables, (iii) insert the sample data, and (iv) show the full contents of the two tables. The header of your script should be something like:/*Your NameIS451 HW5*/ Make sure to start your script file with DROP TABLE commands for the two tables in order to avoid…

Indexing can clearly be very beneficial. Why should younot create an index for every column of every table of yourdatabase?
The file P02_18.xlsx contains daily values of the S&P Index from 1970 to mid-2015. It alsocontains percentage changes in the index from each day to the next. Create a pivot table withaverage of % Change in the Values area and Date in the Rows area. You will see every singledate, with no real averaging taking place. This problem lets you explore how you can groupnaturally on a date variable. For each part below, explain the result briefly. (Note that if you areusing Excel 2016, grouping by date will be done automatically.)a. Group by Month. b. Group by Year.c. Group by Month and Year (select both in the Group dialog box). Can you make it show theyear averages from part b?d. Group by Quarter.e. Group by Month and Quarter. Can you make it show the averages from part c? f. Group by Quarter and Year.g. Group by Month, Quarter, and Year.
