Hi everybody,
I'm new to MySQL and have got the following code that works with Oracle
SQL... After looking at the documentation I realised that DECODE seems to be
reserved for encryption... any idea of how this would work with MySQL? Here
is the code:
The tables are as follows
table table
table
CUSTOMER CUSTOMER_SKILLS SKILL
CUSTOMER_ID (p) CUSTOMER_ID(f) SKILL_ID(p)
CUSTOMER_NAME SKILL_ID (f) SKILL_DESC
(p) Primary Key
(f) Foreign Key
The idea is to select the customer(s) that have 'n' skill(s) and return the
customer name and skill(s) description. The skills are know from the user
input.
SELECT
DECODE (A.SKILLS_ID, B.SKILLS_ID, D.CUSTOMER_NAME, NULL) "Customer
Name", A.SKILL_DESC "Skill Title"
FROM CUSTOMER_DETAILS D, CUSTOMER_SKILLS C, SKILLS B, SKILLS A
WHERE C.SKILLS_ID = A.SKILLS_ID
AND D.CUSTOMER_ID = C.CUSTOMER_ID
AND A.SKILLS_ID IN (1,3,5)
AND B.SKILLS_ID = (SELECT MIN(A.SKILLS_ID)
FROM CUSTOMER_SKILLS A
WHERE A.CUSTOMER_ID =
D.CUSTOMER_ID
AND A.SKILLS_ID IN (1,3,5) )
ORDER BY D.CUSTOMER_NAME, 2;
