/*!   
    Opens the database connection using the given connection options. Returns true on success; otherwise returns false.
    Error information can be retrieved using the lastError() function. Symbian SQL dbs have no \a user, \a password, \a host
    or \a port just file names.
    
    \a connOpts Connection options hold definition for security policies and all parameters that does not contain "POLICY_" will be
    passed to RSqlDatabase. Policy will be filled according to parsed values.

    Value in database wide parameters starts by definition which can be vendorId or secureId. These come directly from TSecurityPolicy class in Symbian. 
    
    POLICY_DB_DEFAULT
    Default security policy which will be used for the database and all database objects. POLICY_DB_DEFAULT must be 
    defined before any other policy definitions can be used.    
    POLICY_DB_READ
    Read database security policy. An application with read database security policy can read from database.    
    POLICY_DB_WRITE:
    Write database security policy. An application with write database security policy can write to database. 
    POLICY_DB_SCHEMA:
    Schema database security policy. An application with schema database security policy can modify
    the database schema, write to database, read from database.   
    
    Format:
    POLICY_DB_DEFAULT=cap1,cap2,cap3,cap4,cap5,cap6,cap7    (Up to 7 capabilities) 
    POLICY_DB_READ=cap1,cap2,cap3,cap4,cap5,cap6,cap7       (Up to 7 capabilities)
    POLICY_DB_WRITE=vendorid,cap1,cap2,cap3                 (Vendor ID and up to 3 capabilities)
    POLICY_DB_SCHEMA=secureid,cap1,cap2,cap3                (Secure ID and up to 3 capabilities)  
    
    Table policies does not support schema policy as database level does.
    
    Table specific parameters would be as:    
    POLICY_TABLE_WRITE=tablename,cap1,cap2,cap3,cap4,cap5,cap6,cap7
    POLICY_TABLE_READ=tablename,cap1,cap2,cap3,cap4,cap5,cap6,cap7    
    
    Vendor Id and Secure id format:    
    vid[0x12345678]                              (Hex)    
    sid[0x12345678]                              (Hex)                        
    
    Example:   
    \code   
    QSqlDatabase database = QSqlDatabase::addDatabase("QSYMSQL", "MyConnection");
    database.setConnectOptions("POLICY_DB_DEFAULT=ReadDeviceData");
    database.setDatabaseName("[12345678]myDatabase");
    bool ok = database.open();   
    \encode    
    
    \code   
    QSqlDatabase database = QSqlDatabase::addDatabase("QSYMSQL", "MyConnection");
    database.setConnectOptions("POLICY_DB_DEFAULT=None; POLICY_DB_WRITE=sid[0x12345678], WriteDeviceData");
    database.setDatabaseName("[12345678]myDatabase");
    bool ok = database.open();   
    \encode    
    
    FOREIGN KEY:  
    Enabling foreign key support from underlying SQLite
    add: "foreign_keys = ON" to your connection options string. This will be passes to SQLite.
   
    Foreign key Example:   
    \code
    QSqlDatabase database = QSqlDatabase::addDatabase("QSYMSQL", "MyConnection");
    database.setDatabaseName("[12345678]myDatabase");
    database.setConnectOptions("foreign_keys = ON");
    bool ok = database.open();
    \encode
