A hоspitаl wаnts tо creаte a patients table with cоlumns: patient_id (unique number, required) full_name (up to 255 characters, required) age (whole number) Which SQL is correct? CREATE TABLE patients (patient_id INT NOT NULL, full_name VARCHAR(255) NOT NULL, age DECIMAL(10,2)); CREATE TABLE patients (patient_id INT NOT NULL, full_name VARCHAR(255) NOT NULL, age INT); CREATE patients TABLE (patient_id INT NOT NULL, full_name TEXT, age INT); CREATE TABLE patients (patient_id VARCHAR(255), full_name INT, age INT); Answer: CREATE TABLE patients (patient_id INT NOT NULL, full_name VARCHAR(255) NOT NULL, age INT); Explanation: INT works for identifiers and ages, VARCHAR(255) is appropriate for names, and NOT NULL ensures mandatory fields. The other options either misuse data types or have invalid syntax.
