[support] Place holders in SQL query

[Austin Einter]

1.
When we do a SQL query, if we want to pass value to query, we make use %d
for integers or %s for strings.
Similarly do we have any place holders for arrays.


2.
I am facing a below typical problem, can somebody tell me what should I do?

Below query works fine.
SELECT skillid FROM {resubmt_skills}  WHERE resubmt_skills.skillname
IN (*'PHP',
'HTML', 'SQL'*)

But in above query search string  *'PHP', 'HTML', 'SQL' *is hard coded.
I want to make the query generic.

Lets say in custom search form, user entered search string PHP, Telecom,
HTML,, so how can I write a generic query.

Thanks
Austin
