TODBCServer

 Open a connection to a ODBC server. The db arguments can be:
 1. Form "odbc://[user[:passwd]@]<host>[:<port>][/<database>][?Driver]",
    e.g.: "odbc://pcroot.cern.ch:3306/test?MySQL".
    Driver argument specifies ODBC driver, which should be used for
    connection. By default, MyODBC driver name is used.
    The uid is the username and pw the password that should be used
    for the connection.
    If uid and pw are not specified (==0), user and passwd arguments from
    URL will be used. Works only with MySQL ODBC, probably with PostrSQL
    ODBC.
 2. Form "odbcd://DRIVER={MyODBC};SERVER=pcroot.cern.ch;DATABASE=test;USER=user;PASSWORD=pass;OPTION=3;PORT=3306;"
    This is a form, which is accepted by SQLDriverConnect function of ODBC.
    Here some other arguments can be specified, which are not included
    in standard URL format.
 3. Form "odbcn://MySpecialConfig", where MySpecialConfig is entry,
    defined in user DSN (user data source). Here uid and pw should be
    always specified.

    Configuring unixODBC under Linux: http://www.unixodbc.org/odbcinst.html
    Remarks: for variants 1 & 2 it is enough to create/configure
    odbcinst.ini file. For variant 3 file odbc.ini should be created.
    Path to this files can be specified in enviromental variables like
      export ODBCINI=/home/my/unixODBC/etc/odbc.ini
      export ODBCSYSINI=/home/my/unixODBC/etc

    Configuring MySQL ODBC under Windows.
    Installing ODBC driver for MySQL is enough to use it under Windows.
    Afer odbcd:// variant can be used with DRIVER={MySQL ODBC 3.51 Driver};
    To configure User DSN, go into Start menu -> Settings ->
    Control panel -> Administrative tools-> Data Sources (ODBC).

    To install Oracle ODBC driver for Windows, one should download
    and install either complete Oracle client (~500 MB), or so-called
    Instant Client Basic and Instant Client ODBC (~20 MB together).
    Some remark about Instant Client:
       1) Two additional DLLs are required: mfc71.dll & msver71.dll
          They can be found either in MS VC++ 7.1 Free Toolkit or
          downloaded from other Internet sites
       2) ORACLE_HOME enviroment variable should be specified and point to
           location, where Instant Client files are extracted
       3) Run odbc_install.exe from account with administrative rights
       3) In $ORACLE_HOME/network/admin/ directory appropriate *.ora files
          like ldap.ora, sqlnet.ora, tnsnames.ora should be installed.
          Contact your Oracle administrator to get these files.
    After Oracle ODBC driver is installed, appropriate entry in ODBC drivers
    list like "Oracle in instantclient10_2" should appiar. Connection
    string example:
     "odbcd://DRIVER={Oracle in instantclient10_2};DBQ=db-test;UID=user_name;PWD=user_pass;";

 Close connection to MySQL DB server.

 Produce TList object with list of available 
 ODBC drivers (isdrivers = kTRUE) or data sources (isdrivers = kFALSE)

 Produce TList object with list of available ODBC drivers
 User must delete TList object aftewards
 Name of driver can be used in connecting to data base in form
 TSQLServer::Connect("odbcd://DRIVER={<drivername>};DBQ=<dbname>;UID=user;PWD=pass;", 0, 0);

 Print list of ODBC drivers in form:
   <name> : <options list>

 Produce TList object with list of available ODBC data sources
 User must delete TList object aftewards
 Name of data source can be used later for connection:
 TSQLServer::Connect("odbcn://<data_source_name>", "user", "pass");

 Print list of ODBC data sources in form:
   <name> : <options list>

 Extract errors, produced by last ODBC function call

 Close connection to MySQL DB server.

 Returns a pointer to a TSQLResult object if successful, 0 otherwise.
 The result object must be deleted by the user.

 Return kTRUE if successfull

 Select a database. Returns 0 if successful, non-zero otherwise.
 Not all RDBMS support selecting of database (catalog) after connecting

 "t%" list all tables starting with "t".
 Returns a pointer to a TSQLResult object if successful, 0 otherwise.
 The result object must be deleted by the user.
