Inserting Information
To insert information right into a database, use the `INSERT INTO` assertion. The syntax is as follows:
INSERT INTO table_name (column1, column2, column3) VALUES (value1, value2, value3);
For instance, the next assertion inserts a brand new row into the `clients` desk:
INSERT INTO clients (identify, tackle, telephone)
VALUES ('John Doe', '123 Most important Avenue', '555-1212');
Updating Information
To replace information in a database, use the `UPDATE` assertion. The syntax is as follows:
UPDATE table_name SET column1 = value1, column2 = value2, column3 = value3 WHERE situation;
For instance, the next assertion updates the identify of the shopper with the ID of `1` to `Jane Doe`:
UPDATE clients SET identify = 'Jane Doe' WHERE id = 1;
Deleting Information
To delete information from a database, use the `DELETE` assertion. The syntax is as follows:
DELETE FROM table_name WHERE situation;
For instance, the next assertion deletes the shopper with the ID of `1`:
DELETE FROM clients WHERE id = 1;
Extra Info
The next desk summarizes the variations between the `INSERT`, `UPDATE`, and `DELETE` statements:
| Assertion | Objective |

Grouping Information
The GROUP BY clause is used to group the information returned by a SELECT assertion. The essential syntax of a GROUP BY clause is:
GROUP BY column_name(s)
Combination Features
Combination features are used to carry out calculations on the information returned by a SELECT assertion. Some widespread combination features embrace:
| Operate | Description |
|---|---|
| COUNT() | Counts the variety of rows in a desk |
| SUM() | Calculates the sum of a column’s values |
