Chapter 3, Problem 3.46RQ
Program Plan Intro
SQL:
- SQL stands for “Structured Query Language”.
- The current version of SQL is “ANSI SQL – 92”.
- It contains constructs which are used to define and process
database . They are executed using DBMS-supplied command prompt. - SQL is not a
programming language. It is text-based and it is also called as data sublanguage. In order to get SQL as a complete programming language, it should be included in scripting languages like Java, C#, and so on.
Table Creation:
Creating table comes under Data Definition Language (DDL). Syntax for creating table is as follows:
CREATE TABLE TABLE_NAME (
Column1 datatype,
Column2 datatype,
…
);
DELETE FROM statement:
“DELETE FROM” statement is used in order to delete existing records (rows and columns) from the table.
Note: It is necessary to use “WHERE” clause when deleting values, because, when it is ignored all the values from the mentioned column name gets deleted.
Syntax:
DELETE FROM table_Name WHERE condition;

Write the SQL statements using the university schema to perform the followingoperations: Delete all takes tuples corresponding to any section of any course withthe word “advanced” as a part of the title; ignore case when matching theword with the title.
The SQL SELECT statement performs case-sensitive comparisons. a. True b. False
True or False?
To select all columns from a table named STUDENTS, we can use the SQL statement ‘’SELECT STUDENTS FROM’’.

The structure of PATHS is as follows, where x1 and x2 represent that there is a path from Coordinate x1 to Coordinate x2 (You can't move from Coordinate x2 to Coordinate x1 ). NAME ΤΥΡE NULLABLE X1 INT FALSE X2 INT FALSE Problem Please write an SQL statement that returns the beginning and end point of each path in PATHS . Sort them by the value of the beginning point in ascending order. Constraints • In the case where a direct path from Coordinate a to Coordinate b is available, no path from Coordinate b to Coordinate a will be given. |x1-x2| = 1 • No path will overlap with one another. Example Suppose that PATHS is as follows: x1 x2 1 2 2 3 4 7 7 6 This table can be visualized as follows: START END END START 7 8. 9 Therefore, your SQL statement must return the following: start end 1 4 8 6arrow_forwardDevelop a PL/SQL block that would go through all the employees from EMPLOYEES table who work in department_id= 90 (there is suppose to be 3 employee who work in Department 90) IN BEGIN END END SECTION; Execute 3 separate of SELECT statement one after the other.
