How to pass dynamic parameters to a MySQL view

Just create the view without the parameters (i.e., to take care of the join only):

CREATE VIEW MYVIEW AS (
SELECT A.FNAME
     , A.LNAME
     , B.EMAIL
     , A.EID AS EID             -- added to be used in the WHERE
     , B.EMAILTYP AS EMAILTYP   -- added to be used in the WHERE
FROM EMPLOYEE A, EMPEMAIL B
WHERE A.EID = B.EID)

And apply the dynamic parameters when you query:

SELECT FNAME, LNAME, EMAIL
FROM   my_view
WHERE  eid = 'your_empId' AND emailtyp = 'your_emailType'

Note the WHERE shown above, it uses the two extra fields declared in the VIEW


You can use this solution with a function -

CREATE FUNCTION func() RETURNS int(11)
  RETURN @var;

CREATE VIEW view1 AS
  SELECT * FROM table1 WHERE id = func();

Using example:

SET @var = 1;
SELECT * FROM view1;
