]- ok .. I choosed wrong word... I'm not native English sorry... but I agree
that if-else-otherwise construct is not so good, for most of the people... I
forgot about it already :")

cond ? then : else ~ otherwise;# i don't know

have many more contexts in Perl 6.66 aren't we ];")::

]- my mistake sorry. There is "..." if u see, so it is more specificaly :
$whereCond = $cond ? ' field > $x AND ' : '' : ' field < $x AND';
$Query = qq{ SELECT .... FROM ... WHERE $whereCond field2 = (SELECT fieldX
FROM blah WHERE fieldA = $id )};
is this way ok....and this is just example, can figure out some other at the
moment, but that is the reason I'm posting here to see all your opinions if
it is worth it. If (not) I'm ok ( sorry for your time) else (then OK)
otherwise (will see) :")

PS. What type of query to build :
$qtype = cond ? SELECT : INSERT : UPDATE;
or I'm building a query for update or insert how to decide how the current
key -> value pair will be used :
this time we are deciding between INSERT, UPDATE or UPDATE-WHERE clause :
$kv .= $qtype ? do {$values .= "$v, ", "$k, "} : "$k = $v, " : "$k = $v AND
";#is this correct
later :
chop,chop...substr..!!
$query = "INSERT INTO blah ( $kv ) VALUES ( $values )";
OR
$query = "UPDATE blah SET $kv WHERE something...";
OR
$query = "UPDATE ..something... WHERE $kv";
More examples :
=============
index(ref $var, 'A') - 1 ? SCALAR-LVALUE-case : HASH-case : ARRAY-case;
i.e.
index(ref $var) - 1 ? $v = $var : $v alias $var : @v = @$var;
=============
form-field-type ? <select> : <input> : <textarea>;
=============
output-type ? print-to-web <BR> : print-to-stdout \n : print-to-STDERR;
=============
$x = $a <=> $b ? $a : $default : $b;
can figure out more at the moment :")
