Answer:
The Statement for selecting values from the table in SQL is given below,
SELECT vendor_name, vendor_contact_last_name, vendor_contact_first_name FROM Vendors;
Explanation:
SQL stands for Structured query language which is used to insert, update, delete and modify the value in a table.
There are five types of SQL-
1. Data definition language
2. Data manipulation language
3. Data control language
4. Transaction Control Language
5. Data Query Language
The SELECT statement comes under DDL which is used to select and display values from a table.
We can use select statement in two ways-
1. SELECT column_name1, column_name2 ........column_nameN FROM Table_name;
2. SELECT * FROM tablename; ( This is used to select all values from the table name)
We can also give conditions using WHERE clause while selecting values.
Answer:
Variable, operator, expression, value.
Explanation:
We could use variables, operators, expressions, and values in a mathematical formula, we're going to do an example with every part.
For this example we're going to use a simple sum formula:
First, we have 3 variables:
sum;
sum1;
sum2;
Second, we have 3 operators:
=, + and *
Third, we have our expression and 1 value:
sum = sum1 + (sum2 * 5);
(sum2 * 5) = expression;
5 = value;
We're going to see the result when we print the variable sum.
