I create a function called triangleType which use to define type of triangle; however, the console shows an error: SELECT triangle_type(A,B,C) FROM TRIANGLES LIMIT 0, 1000 Error Code: 1305. FUNCTION practice.triangle_type does not exist 0.00055 sec. I am not sure how to locate this function. I try to use PRACTICE.TRIANGLES but it doesn't really work. Thanks.

Schema: PRACTICE
Tables: TRIANGLES



Code:

DELIMITER $$
USE `PRACTICE`$$

CREATE FUNCTION triangleType(A int, B int, C int)
RETURNS varchar(14)

DETERMINISTIC

BEGIN
DECLARE triangle_type VARCHAR(14);
IF A = B AND B = C AND ((A+B) >C OR (A+C) >B OR (B+C) > A) THEN
SET triangle_type = "Equilateral";

ELSE IF (A=B OR B=C OR A=C) AND ((A+B) >C OR (A+C) >B OR (B+C) > A) THEN
SET triangle_type = "Isosceles";

ELSE IF (A<>B AND B<>C AND A<>C) AND ((A+B) >C OR (A+C) >B OR (B+C) > A)THEN
SET triangle_type = "Scalene";

ELSE
SET triangle_type = "Not A Triangle";
END IF;

RETURN(triangle_type);

END
DELIMITER ;


USE `PRACTICE`;
SELECT triangle_type(A,B,C) FROM PRACTICE.TRIANGLES;
