What is the difference between scalar function and vector function in SQL DATABASE? Note: Question is based on SQL DATABASE.

Oracle PL/SQL Implement a trigger to the following constraints: Meter readers can only read a maximum of 5 meters in any given calendar month. Customers who do not pay their bill within 60 days will their water supply cut off. Once a customer has had their supply cut off, the person or business responsible for the bill will not be able to create a new account at a different service address until such time as their arrears have been cleared.

You are interested in analyzing some hard-to-obtain data from two separate databases. Each database contains n numerical values—so there are 2n values total—and you may assume that no two values are the same. You'd like to determine the median of this set of 2n values, which we will define here to be the nth smallest value. However, the only way you can access these values is through queries to the databases. In a single query, you can specify a value k to one of the two databases, and the chosen database will return the kth smallest value that it contains. Since queries are expensive, you would like to compute the median using as few queries as possible. Give a recursive algorithm that finds the median value using at most O(logn) queries.   Explain why your algorithm only requires at most O(log(n)) queries to locate the median?

Which of these statements is true about relation partitioning?     It places different rows from the same table on different machines, allowing for the computing of different query predicates in parallel on different machines.   It places different columns from the same table on different machines, which allows for computing different query predicates in parallel on different machines.   It places certain tables on one machine and others on a different machine, allowing different query subexpressions in the same plan to be computed in parallel on different machines.   It replicates and indexes data, which generally improves query performance.
