Concept explainers

Intermediate SQL Concepts

A query is a request for data or information from one or more database tables. This information could be presented in the form of pictorials, graphs, or complicated findings which helps in easy interpretation. Structured Query Language (SQL) is the most widely used programming language for retrieving and organizing data from relational databases. Collection of tables with rows and columns is referred to as a database. SQL is the language of databases. It makes it easier to extract specific data from databases, which can then be used for analysis.

Question

In Oracle database, if we have `lname` field in our table, then regardless of how the values have been entered in `lname`, we can convert them into lower or initcap, then check their existence in the WHERE clause. This can be done by including the following in the WHERE clause:

I: `initcap(lname)='Adam'` and `lower(lname)='adam'`
II: `INITCAP(lname)='Adam'` and `LOWER(lname)='adam'`
I & II: are correct
I & II: are not correct

Options:
- ○ I & II: are not correct
- ○ I
- ○ I & II: are correct
- ○ II

In an Oracle database, if we have any field such as a Job_Title field in any of our tables, we can use the DECODE function to sort the result based on our own numerical value. This can be done by including the following in the ORDER BY clause:

I. `ORDER BY DECODE(job-title,'Manager',3,'Assistant',2,'Sales Rep',1) DESC`

II. `ORDER BY DECODE(job-title,'Manager',3,'Assistant',2,'Sales Rep',1) ASC`

- III: I and II are correct
- IV: I and II are incorrect
- II: Only II is correct
- I: Only I is correct

This prompt presents two SQL ORDER BY clauses using the DECODE function. It lists options to determine the correctness of each clause in sorting job titles either in descending order (I) or ascending order (II).
