Module pydo.dbi

Classes
`ConnectionPool`	a connection pool for a single connection alias.

Function Summary
	`delAlias(alias)` delete a connection alias if it has already been initialized; does nothing otherwise
	`getConnection(alias, create)` get a connection given a connection alias
	`initAlias(alias, driver, connectArgs, pool, verbose, init)` initializes a connection alias with the stated connection arguments.

Function Details

delAlias(alias)

delete a connection alias if it has already been initialized; does nothing otherwise

getConnection(alias, create=True)

get a connection given a connection alias

initAlias(alias, driver, connectArgs, pool=None, verbose=False, init=None)

initializes a connection alias with the stated connection arguments.

It can cause confusion to let this be called repeatedly; you might think you are initializing it one way and not realize it is being initialized elsewhere differently. Therefore, this raises a ValueError if the alias is already initialized with different data. Multiple initializations with the same data (such as happens when a module calling initAlias is reloaded) are permitted.

If you need to change the connect values at runtime, call delAlias before initAlias.
