Re: Synthesize support for Statement.getGeneratedKeys()?

Hi Kris, were you able to look at this? If time wont permit that I'll
dig back in; though I'd prefer not to duplicate any work your're doing,
of course.

Thank,
ken

Kris,

Strange about the patch. Aside from the import stmts, only the method
below is changed in that source file:

public int executeUpdate(String sql, String columnNames[]) throws
SQLException
{
//fix-me "The driver will ignore the array if the SQL statement is
not an INSERT statement"
//fix me : impl NO_GENERATED_KEYS & RETURN_GENERATED_KEYS
if (columnNames==null || columnNames.length==0)
return executeUpdate(sql);
//should never reallocate
StringBuffer s = new
StringBuffer(12+sql.length()+(columnNames.length*32));
s.append(sql);
s.append('\n');
s.append("RETURNING");
s.append(' ');
for (int i=0; i<columnNames.length; i++)
{
if (i!=0)
s.append(',');
s.append(columnNames[i]);
}
return executeUpdateGetResults(s.toString());
//throw new PSQLException(GT.tr("Returning autogenerated keys is
not supported."), PSQLState.NOT_IMPLEMENTED);
}
