catch exception in sqlite3pp

I'm using sqlite3pp to manipulate database. When I tried to insert one record twice in the same table by running,

 sqlite3pp::command cmd(db, "INSERT INTO Groups (Name) VALUES (?)");
 cmd.binder() << "Group_one";
 cmd.execute();

it throwed an excpetion and showed me this:

libc++abi.dylib: terminating with uncaught exception of type sqlite3pp::database_error: UNIQUE constraint failed: Groups.Name

But I'm not sure what type of exception should I use to catch? I tried

try {
    cmd.execute();
} catch (std::exception e) {}

But it doesn't work. Can anyone help me here? Thanks!
