Override newline delimiter

[d10xa]

echo "x,1;y,2;z,3" | q -d "," "select * from -"

will produce x,1;y,2;z,3

is it possible to perceive another character at the end of the line?

The solution is not q specific but works in general in UNIX like systems. Just combine with another tool, here tr:

$ echo "x,1;y,2;z,3" | tr ';' '\n' | q -d "," "select * from -"
x,1
y,2
z,3
