[CWB] Query lock violation

[Hardie, Andrew]

The exec_query method only allows you to execute a query; you'll get an error message if you attempt any other command. This is for safety in web interfaces where user-submitted data might be passed to CQP (with query lock on, the damage malicious input can do is limited). For your purposes, use ::exec not ::exec_query.

Hello

I was trying to use CWB::CQP exec_query method, with

@lines = $cwb->exec_query($query);

where $query holds

A = "europa"; cat A;

But I get
WARNING: query lock violation attempted
PARSE ERROR

Any hint on what's going on?

Thank you in advance,
Alberto
