\b\fs28 Overview
\b0\fs24 \
\
In order to run this example, you need to have a Sybase server with a pubs database installed. This example uses the 
\b SybaseDemo.dbmodela
\b0  model file (also available under /NextDeveloper/Examples/DatabaseKit/Models).\

\i For Oracle users, you can modify the TableViewController.m file to comment out  #define SYBASE_DEMO  and recompile the application.\
\

\i0 This example shows how you can define a DBTableView and a DBModule programmatically instead of using the corresponding Interface Builder UI Objects . 
\fc1\cf1  It also shows how you can change the sort order every time the columns in the tableview are rearranged. The sort property is determined by the identifiers of the tableview columns.\

\b0 \
In order to load an Adaptor dynamically, you need to add the
\b  OTHER_LDFLAGS
\b0  definition (see the 
\b Makefile.preamble
\b0 ). You also need to add the
\b  libdbkit_s.a
\b0  library into your
\b  PB.project
\b0  under 
\b libraries
\b0  in order to use the DBKit API. \
