What statement might you use to see the rows that will be impacted before executing a DELETE or UPDATE?The Developers team also wants you to ensure that emails are converted to lowercase after an update operation. Currently, new insertions are guaranteed to have lowercase emails, but there is no such guarantee for legacy emails. Therefore, the team wants to ensure that emails are being retained in a lowercase irrespective of any changes in the database. Create a new TRIGGER called email_update for the USERS table that runs before an UPDATE operation. Task Create a TRIGGER to run on the USERS table before any UPDATE operation.Task 5: The Developers team also wants you to ensure that emails are converted to lowercase after an update operation.

Define a variable named starray and add these two document to the variable. (You are storing more than one document so you need to define an array.) write the command to define the array: Now, use the starray array to insert the documents to your collection student.

Did in Student is a foreign key referencing the…You notice that the database instance takes a long time to start up after the instance crash. How will you resolve the problem? a) Increase the size of the redo log files b) Decrease the number of redo log members c) Set LOG_CHECKPOINT_TO_ALERT to TRUE d) Decrease the value for the FAST_START_MTTR_TARGET initialization parameterTask 5: The Developers team also wants you to ensure that emails are converted to lowercase after an update operation.
