Is it possible to set conditions on a table entry? For example, if you have
a data set with these cols:
ts = DateTimeCol () // time stamp
id_str = StringCol // string identifier
Can I create a condition that forces the ts/id_str combination within each
row to be unique?

Create a unique index in the database.

Programmers don't die, they just GOSUB without RETURN.
