Class IfxDriver

java.lang.Object

com.informix.jdbc.IfxDriver

All Implemented Interfaces:

java.sql.Driver

public class IfxDriver
extends java.lang.Object
implements java.sql.Driver

The Java SQL framework allows for multiple database drivers.

Each driver should supply a class that implements the Driver interface.

The DriverManager will try to load as many drivers as it can find and then for any given connection request, it will ask each driver in turn to try to connect to the target URL.

It is strongly recommended that each Driver class should be small and standalone so that the Driver class can be loaded and queried without bringing in vast quantities of supporting code.

When a Driver class is loaded, it should create an instance of itself and register it with the DriverManager. This means that a user can load and register a driver by doing Class.forName("foo.bah.Driver").

Method Detail

connect

public java.sql.Connection connect(java.lang.String url,
                          java.util.Properties prop)
                            throws java.sql.SQLException

Try 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 JDBC 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 java.util.Properties argument can be used to passed arbitrary string tag/value pairs as connection arguments. Normally at least "user" and "password" properties should be included in the Properties.

 We support url's of the form:
  jdbc:://:[/dbname][:name=(value)
    [;name=(value)]...]


   everything in brackets '[ ]' is optional
   Also, the database name ([/dbname]) can be a name=value property.
 

Specified by:

connect in interface java.sql.Driver

Parameters:

url - - The URL of the database to connect to

prop - - a list of arbitrary string tag/value pairs as connection arguments; normally at least a "user" and "password" property should be included Can be null

Returns:

a Connection to the URL

Throws:

java.sql.SQLException

acceptsURL

public boolean acceptsURL(java.lang.String url)
                   throws java.sql.SQLException

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 don't.

Specified by:

acceptsURL in interface java.sql.Driver

Parameters:

url - - The URL of the database.

Returns:

True if this driver can connect to the given URL.

Throws:

java.sql.SQLException

getPropertyInfo

public java.sql.DriverPropertyInfo[] getPropertyInfo(java.lang.String url,
                                            java.util.Properties prop)
                                              throws java.sql.SQLException

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, 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.

Specified by:

getPropertyInfo in interface java.sql.Driver

Parameters:

url - - The URL of the database to connect to.

prop - - 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:

java.sql.SQLException

getMajorVersion

public int getMajorVersion()

Get the driver's major version number.

Specified by:

getMajorVersion in interface java.sql.Driver

Returns:

major version number

getMinorVersion

public int getMinorVersion()

Get the driver's minor version number.

Specified by:

getMinorVersion in interface java.sql.Driver

Returns:

minor version number

getMajorMinorVersion

public static int getMajorMinorVersion()

Get the driver's major-minor version number.

Returns:

major-minor version number

jdbcCompliant

public boolean jdbcCompliant()

Report whether the Driver is a genuine JDBC COMPLIANT (tm) driver. A driver may only report "true" here if it passes the JDBC compliance tests, otherwise it is required to return false.

JDBC compliance requires full support for the JDBC API and full support for SQL 92 Entry Level. It is expected that JDBC compliant drivers will be available for all the major commercial databases. This method is not intended to encourage the development of non-JDBC compliant drivers, but is a recognition of the fact that some vendors are interested in using the JDBC API and framework for lightweight databases that do not support full database functionality, or for special databases such as document information retrieval where a SQL implementation may not be feasible.

Specified by:

jdbcCompliant in interface java.sql.Driver

Returns:

true if compliant

getJDBCVersion

public static java.lang.String getJDBCVersion()

Return the current release version of JDBC.

getParentLogger

public java.util.logging.Logger getParentLogger()
                                         throws java.sql.SQLFeatureNotSupportedException

Specified by:

getParentLogger in interface java.sql.Driver

Throws:

java.sql.SQLFeatureNotSupportedException

getPreparedStatementInfo

public static java.util.List<org.bson.BSONObject> getPreparedStatementInfo()
