- Method select_db
void select_db(string dbname)
Before querying a database you have to select it. This can be accomplished in two ways: the first is calling the create function with two arguments, another is calling it with one or no argument and then calling select_db. You can also use this function to change the database you're querying, as long as it is on the same server you are connected to.
This function CAN raise exceptions in case something goes wrong (for example: unexistant database, insufficient permissions, whatever).
