Initial import from the monolithic Qt.
This is the beginning of revision history for this module. If you want to look at revision history older than this, please refer to the Qt Git wiki for how to use Git history grafting. At the time of writing, this wiki is located here: http://qt.gitorious.org/qt/pages/GitIntroductionWithQt If you have already performed the grafting and you don't see any history beyond this commit, try running "git log" with the "--follow" argument. Branched from the monolithic repo, Qt master branch, at commit 896db169ea224deb96c59ce8af800d019de63f12

+Before building the Qt library, the Qt SQL module can be enabled for
+specific databases using 'configure'. 'configure' is located at the
+top of your QTDIR.
+
+Specific databases drivers can be enabled using one of the following
+options:
+
+ ./configure [-qt-sql-<driver>] [-plugin-sql-<driver>]
+
+or disabled using the following option:
+
+ ./configure [-no-sql-<driver>]
+
+Where <driver> is the name of the driver, for example 'psql'. This
+will configure the Qt library to compile the specified driver into
+the Qt lib itself.
+
+For example, to build the PostgreSQL driver directly into the Qt
+library, configure Qt like this:
+
+ ./configure -qt-sql-psql
+
+In addition, you may need to specify an extra include path, as some
+database drivers require headers for the database they are using,
+for example:
+
+ ./configure -qt-sql-psql -I/usr/local/include
+
+If instead you need to build the PostgreSQL driver as a dynamically
+loaded plugin, configure Qt like this:
+
+ ./configure -plugin-sql-psql
+
+To compile drivers as dynamically loaded plugins, see the
+QTDIR/plugins/src/sqldrivers directory. Use 'configure -help'
+for a complete list of configure options. See the Qt documentation
+for a complete list of supported database drivers.

+ \class QSqlDatabase
+ \brief The QSqlDatabase class represents a connection to
+ a database.
+
+ \ingroup database
+
+ \inmodule QtSql
+
+ The QSqlDatabase class provides an interface for accessing a
+ database through a connection. An instance of QSqlDatabase
+ represents the connection. The connection provides access to the
+ database via one of the \l{SQL Database Drivers#Supported
+ Databases} {supported database drivers}, which are derived from
+ QSqlDriver. Alternatively, you can subclass your own database
+ driver from QSqlDriver. See \l{How to Write Your Own Database
+ Driver} for more information.
+
+ Create a connection (i.e., an instance of QSqlDatabase) by calling
+ one of the static addDatabase() functions, where you specify
+ \l{SQL Database Drivers#Supported Databases} {the driver or type
+ of driver} to use (i.e., what kind of database will you access?)
+ and a connection name. A connection is known by its own name,
+ \e{not} by the name of the database it connects to. You can have
+ multiple connections to one database. QSqlDatabase also supports
+ the concept of a \e{default} connection, which is the unnamed
+ connection. To create the default connection, don't pass the
+ connection name argument when you call addDatabase().
+ Subsequently, when you call any static member function that takes
+ the connection name argument, if you don't pass the connection
+ name argument, the default connection is assumed. The following
+ snippet shows how to create and open a default connection to a
+ PostgreSQL database:
+
+ \snippet doc/src/snippets/sqldatabase/sqldatabase.cpp 0
+
+ Once the QSqlDatabase object has been created, set the connection
+ parameters with setDatabaseName(), setUserName(), setPassword(),
+ setHostName(), setPort(), and setConnectOptions(). Then call
+ open() to activate the physical connection to the database. The
+ connection is not usable until you open it.
+
+ The connection defined above will be the \e{default} connection,
+ because we didn't give a connection name to \l{QSqlDatabase::}
+ {addDatabase()}. Subsequently, you can get the default connection
+ by calling database() without the connection name argument:
+
+ \snippet doc/src/snippets/sqldatabase/sqldatabase.cpp 1
+
+ QSqlDatabase is a value class. Changes made to a database
+ connection via one instance of QSqlDatabase will affect other
+ instances of QSqlDatabase that represent the same connection. Use
+ cloneDatabase() to create an independent database connection based
+ on an existing one.
+
+ If you create multiple database connections, specify a unique
+ connection name for each one, when you call addDatabase(). Use
+ database() with a connection name to get that connection. Use
+ removeDatabase() with a connection name to remove a connection.
+ QSqlDatabase outputs a warning if you try to remove a connection
+ referenced by other QSqlDatabase objects. Use contains() to see if
+ a given connection name is in the list of connections.
+
+ Once a connection is established, you can call tables() to get the
+ list of tables in the database, call primaryIndex() to get a
+ table's primary index, and call record() to get meta-information
+ about a table's fields (e.g., field names).
+
+ \note QSqlDatabase::exec() is deprecated. Use QSqlQuery::exec()
+ instead.
+
+ If the driver supports transactions, use transaction() to start a
+ transaction, and commit() or rollback() to complete it. Use
+ \l{QSqlDriver::} {hasFeature()} to ask if the driver supports
+ transactions. \note When using transactions, you must start the
+ transaction before you create your query.
+
+ If an error occurrs, lastError() will return information about it.
+
+ Get the names of the available SQL drivers with drivers(). Check
+ for the presence of a particular driver with isDriverAvailable().
+ If you have created your own custom driver, you must register it
+ with registerSqlDriver().

+
+ This overload is useful when you want to create a database
+ connection with a \l{QSqlDriver} {driver} you instantiated
+ yourself. It might be your own database driver, or you might just
+ need to instantiate one of the Qt drivers yourself. If you do
+ this, it is recommended that you include the driver code in your
+ application. For example, you can create a PostgreSQL connection
+ with your own QPSQL driver like this:
+
+ \snippet doc/src/snippets/code/src_sql_kernel_qsqldatabase.cpp 5
+ \codeline
+ \snippet doc/src/snippets/code/src_sql_kernel_qsqldatabase.cpp 6
+
+ The above code sets up a PostgreSQL connection and instantiates a
+ QPSQLDriver object. Next, addDatabase() is called to add the
+ connection to the known connections so that it can be used by the
+ Qt SQL classes. When a driver is instantiated with a connection
+ handle (or set of handles), Qt assumes that you have already
+ opened the database connection.
+
+ \note We assume that \c qtdir is the directory where Qt is
+ installed. This will pull in the code that is needed to use the
+ PostgreSQL client library and to instantiate a QPSQLDriver object,
+ assuming that you have the PostgreSQL headers somewhere in your
+ include search path.
+
+ Remember that you must link your application against the database
+ client library. Make sure the client library is in your linker's
+ search path, and add lines like these to your \c{.pro} file:
+
+ \snippet doc/src/snippets/code/src_sql_kernel_qsqldatabase.cpp 7
+
+ The method described works for all the supplied drivers. The only
+ difference will be in the driver constructor arguments. Here is a
+ table of the drivers included with Qt, their source code files,
+ and their constructor arguments:
+
+ \table
+ \header \i Driver \i Class name \i Constructor arguments \i File to include
+ \row
+ \i QPSQL
+ \i QPSQLDriver
+ \i PGconn *connection
+ \i \c qsql_psql.cpp
+ \row
+ \i QMYSQL
+ \i QMYSQLDriver
+ \i MYSQL *connection
+ \i \c qsql_mysql.cpp
+ \row
+ \i QOCI
+ \i QOCIDriver
+ \i OCIEnv *environment, OCISvcCtx *serviceContext
+ \i \c qsql_oci.cpp
+ \row
+ \i QODBC
+ \i QODBCDriver
+ \i SQLHANDLE environment, SQLHANDLE connection
+ \i \c qsql_odbc.cpp
+ \row
+ \i QDB2
+ \i QDB2
+ \i SQLHANDLE environment, SQLHANDLE connection
+ \i \c qsql_db2.cpp
+ \row
+ \i QTDS
+ \i QTDSDriver
+ \i LOGINREC *loginRecord, DBPROCESS *dbProcess, const QString &hostName
+ \i \c qsql_tds.cpp

+ \i QIBASE
+ \i QIBaseDriver
+ \i isc_db_handle connection
+ \i \c qsql_ibase.cpp
+ \endtable
+
+ The host name (or service name) is needed when constructing the
+ QTDSDriver for creating new connections for internal queries. This
+ is to prevent blocking when several QSqlQuery objects are used
+ simultaneously.
+
+ \warning Adding a database connection with the same connection
+ name as an existing connection, causes the existing connection to
