INSERT INTO Employee VALUES ('        John', 'London', 3000);
INSERT INTO Employee VALUES ('        Marry', 'New York', 2750);
INSERT INTO Employee VALUES ('      Jo', 'Paris', 2800);
INSERT INTO Employee VALUES ('      Kim', 'Amsterdam', 3100);

-- see the result
SELECT * FROM Employee;

The query will produce the following result:

NameCitySalary
        JohnLondon3000
        MarryNew York2750

To remove the leading spaces from the Name column of the Employee table, the following query can be used:

UPDATE Employee SET Name = LTRIM(Name);

-- see the result
SELECT * FROM Employee;
