You can set it to the output of a variable, for example \set x `echo foo` but I haven't been able to trick it into actually reading something. One would think something like: \set x `set /p Z= && echo %Z%` would work, but it doesn't. One reason for this is that %Z% is actually resolved at parsing time. it's a pain in CMD language, but that's how it works. :-( //Magnus ---(end of broadcast)--- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq

[GENERAL] user input during runtime
Hello All, I want to prompt user to input some value and do some action on that value in runtime of a sql script. Is there any psql command to do this ?? I can use \echo do display massage but to take input what is the command? Thanks in advance With Regards Ashish Karalkar
