Final answer:
The CRUD operation for Delete in SQL databases is represented by the 'DELETE' command, which removes records from a table that match a certain condition.
Step-by-step explanation:
In the context of CRUD operations, which stands for Create, Read, Update, and Delete, the command that represents the D (delete) operation varies depending on the specific database or data storage system being used. However, in SQL, the standard language for dealing with relational databases, the command to delete a record is typically expressed as:
DELETE FROM table_name WHERE condition;
For example, if you wanted to delete a record from a table called 'users' where the 'id' is equal to 10, you would use the following SQL command:
DELETE FROM users WHERE id = 10;
It's important to note that deletion commands can be potentially dangerous, as they remove data permanently from the database. Therefore, they should be used with caution, and appropriate permissions should be enforced to prevent accidental or malicious data loss.
