All keywords are used with WHERE.
LIKE
LIKE is used to map values with String including some
characters. There are two special symbols: percent %, replaced for many characters
and underscore _, replaced for only one character.
Examples
SELECT JOB_TITLE FROM JOBS
WHERE JOB_TITLE LIKE ‘S%’;
The results are job titles starting with S.
Examples
SELECT JOB_TITLE FROM JOBS
WHERE JOB_TITLE LIKE ‘S_l%’;
The
results are job titles starting with S, any character at the second index, l at
the third index.
BETWEEN
BETWEEN is used to check the condition when the values are
in a range or not.
Examples
SELECT JOB_TITLE, MIN_SALARY FROM JOBS
WHERE MIN_SALARY >= 4000 AND MIN_SALARY <= 9000;
We could use BETWEEN … AND… for this case:
SELECT JOB_TITLE, MIN_SALARY FROM JOBS
WHERE MIN_SALARY BETWEEN 4000 AND 9000;
IN
Examples
SELECT JOB_TITLE, MIN_SALARY FROM JOBS
WHERE MIN_SALARY = 4000 OR MIN_SALARY = 9000 OR MIN_SALARY = 6000;
When
we want to check the value that is on one set or not, we could use IN:
SELECT JOB_TITLE, MIN_SALARY FROM JOBS
WHERE MIN_SALARY IN (4000, 6000, 9000);
NOT
We
could use NOT with BETWEEN, LIKE or IN:
SELECT JOB_TITLE, MIN_SALARY FROM JOBS
WHERE MIN_SALARY NOTE BETWEEN 4000 AND 9000;
