· Add or delete a version

The following code creates a new sub-version based on the default version:

Seconnection conn = getconn ();

If (Conn! = NULL ){

Try {

Seversion v_1 = new seversion (Conn, seversion. se_qualified_default_version_name );

V_1.setname ("v_1 ");

V_1.create (true, v_1 );

} Catch (seexception e ){

E. printstacktrace ();

} Finally {

Try {

Conn. Close ();

} Catch (seexception e ){

E. printstacktrace ();

}

}

}

It is easier to delete a version:

Seconnection conn = getconn ();

If (Conn! = NULL ){

Try {

Seversion v_1 = new seversion (Conn, "v_1 ");

V_1.delete ();

} Catch (seexception e ){

E. printstacktrace ();

} Finally {

Try {

Conn. Close ();

} Catch (seexception e ){

E. printstacktrace ();

}

}

}

· Edit a version

The key to version editing is to manage the version status. The following code shows how to delete a record from a version Dataset:

Seconnection conn = getconn ();

If (Conn! = NULL ){

Try {

Seversion version = new seversion (Conn, "V1 ");

Seobjectid oldstateid = version. getstateid ();

Sestate oldstate = new sestate (Conn, oldstateid );

If (oldstate. isopen ()){

Try {

Oldstate. Close ();

} Catch (exception e ){

E. printstacktrace ();

}

}

Sestate newstate = new sestate (conn );

Newstate. Create (oldstateid );

Version. changestate (newstate. GETID ());

Sedelete delete = new sedelete (conn );

Delete. setstate (newstate. GETID (),

New seobjectid (sestate. se_null_state_id ),

Sestate. se_state_diff_nocheck );

Delete. fromtable ("test", "objectid = 3 ");

Delete. Close ();

} Catch (seexception e ){

E. printstacktrace ();

} Finally {

Try {

Conn. Close ();

} Catch (seexception e ){

E. printstacktrace ();

}

}

}
