How can create a query for this situation

Question

I have a table follow:

EMPLOYEE(ID, FULL_NAME, GENDER, PROVINCE, AGE)

and I set value follow:

SQL

INSERT INTO EMPLOYEE(ID, FULL_NAME, GENDER, PROVINCE, AGE)
VALUES(1, 'David Jam', 'male', 'LA', 20),
(2, 'ELENA QUEEN', 'female', 'LA', 21)

You can see my FULL_NAME field has a space. And we can know it divides to first name and last name. Now I want to use a query to SELECT the first name of employee.
Who have any idea for this problem?

Thank you

Select the full_name field and separate the name in your code, or better yet store the firstname\lastname values in their own fields and when you need to show the full name you just combine them together in your code.

Can you give to me a clear example for separate the name?

You haven't said what programming language you are using. Regardless, just google "separate string on words <insert name of your language here>"

Your SQL code shouldn't be doing things like splitting strings, that should be done by the presentation component. If you need the first name as a data entity then it should be stored in its own field. However I'm sure if you google "split string sql" you'll still find plenty of examples.

I seconf OriginalGriff's opinion, concatenating first and last name to the same field is a bad idea. As already pointed out store them in separate columns and your operations will be much simpler.

To throw another kind of solution, typically the string after the last space is the last name so in order to find the last name you cuold have something like

SQL

SELECT REVERSE( SUBSTRING( REVERSE(FULL_NAME), 0, CHARINDEX (' ', REVERSE(FULL_NAME))))
FROM EMPLOYEE;

But as said, the best option is to store them separately.

You can do it - but it's not a good idea. A better solution is to split it to hold the "first name" and "second name" in separate fields (if only because some people have and use three names, so an assumption that a single space separates them is not necessarily true.
But this will split them and return the first "word":

SQL

SELECT SUBSTRING(FULL_NAME, 0, CHARINDEX (' ', FULL_NAME)) AS [First Name] FROM EMPLOYEE
