Dynamic where clause

[basilex]

Guys!
The question is:

How could I create dynamic WHERE clause?
Database contains chunks of the query conditions (to create another query) described below:

"IN ('active', 'inactive')"
"LIKE 'Some conditi%'"
"'Red' AND 'Blue' AND 'Green' "

and I need to create such WHERE clauses dynamically... (
Probably it's time to think about some additional mysterious interface in sqlc
to make it possible execute queries like sqlx is doing right now?

Any help would be appreciated.
Thanx!
