If I knew what an apex was, I could tell you. 8-) I don't know of any
character that causes a problem except a single-quote, so I will
assume that is what you mean.

	[cgi name=yourparam filter=sql keep=1]

Remove the keep=1 if you want the value to be permanently changed
to the filtered version.

By the way, backslash does not escape for most SQL implementations;
you double the single-quote (apex?) character.

Hmm. You must not have searched on "filter".

You can add filters to IC to filter anything -- there should
be many examples of how to make one.

CodeDef remove_apex Filter 
CodeDef remove_apex Routine <<EOR
sub {
	my $value = shift;
	my $apex = "?";
	$value =~ s/$apex/\\$apex/g;
	return $value;

If that goes in catalog.cfg, then

    [cgi name=yourparam filter=remove_apex keep=1]

will provide the filtered value. This is a faster version

    [filter op=remove_apex interpolate=1][cgi yourparam][/filter]
