Disconnecting and reconnecting many times to do
execute procedure test_es1;
on each attachment shows that the column number changes randomly, hence it seems uninitialized var.

I'm wondering what is more correct for this case: "line 0, column 0" or "line 1, column 1".

To Dmitry Yemanov
The same as for empty DSQL query, of course.

This *is* an empty DSQL query :-) Perhaps more logical would be to throw some special error, e.g. "cannot prepare empty statement".

It seems I have already found the answer. We have now:

if \(\!string\)
\{
	ERRD\_post\(Arg::Gds\(isc\_sqlerr\) << Arg::Num\(\-104\) <<
			  // Unexpected end of command
			  // CVC: Nothing will be line 1, column 1 for the user\.
			  Arg::Gds\(isc\_command\_end\_err2\) << Arg::Num\(1\) << Arg::Num\(1\)\);
\}

i.e. "line 1, column 1" is reported when the user passes the NULL pointer. I believe it should be extended to handle the valid pointer but zero string length, so that the issue would be resolved automagically.
