Methods' Details |
connect
- Description
- attempts to make a database connection to the given URL.
The driver should return
NULL
if it realizes it is the wrong kind
of driver to connect to the given URL. This will be common, as when
the driver manager is asked to connect to a given URL it passes
the URL to each loaded driver in turn.
The driver should raise a
SQLException
if it is the right
driver to connect to the given URL, but has trouble connecting to
the database.
The info argument can be used to pass arbitrary
string tag/value pairs as connection arguments.
Normally at least "user" and "password" properties should be
included in the Properties. For a JDBC driver also the Java class must
be supplied in the property named JavaDriverClass, and a class path (a
space-separated list of URLs) needed to locate that class can optionally
be supplied in a property named JavaDriverClassPath.
Possible property value names are when supported by the driver:
- Parameter url
- is the URL of the database to which to connect.
- Parameter info
- a list of arbitrary string tag/value pairs as connection arguments. Normally at least a "user" and "password" property should be included.
- Returns
- a Connection object that represents a connection to the URL
- Throws
- SQLException
if a database access error occurs

acceptsURL( |
[in] string |
url ) |
raises( |
SQLException ); |
- Description
- returns true if the driver thinks that it can open a connection
to the given URL. Typically drivers will return true if they
understand the subprotocol specified in the URL and false if
they do not.
- Parameter url
- is the URL of the database to which to connect.
- Returns
- true if this driver can connect to the given URL.
- Throws
- SQLException
if a database access error occurs.

getPropertyInfo
- Description
- gets information about the possible properties for this driver.
The getPropertyInfo method is intended to allow a generic GUI tool to
discover what properties it should prompt a human for in order to get
enough information to connect to a database. Note that depending on
the values the human has supplied so far, additional values may become
necessary, so it may be necessary to iterate though several calls
to getPropertyInfo.
- Parameter url
- is the URL of the database to which to connect.
- Parameter info
- is a proposed list of tag/value pairs that will be sent on
connect open.
- Returns
- an array of DriverPropertyInfo objects describing possible
properties. This array may be an empty array if no properties
are required.
- Throws
- SQLException
if a database access error occurs.
