Обсуждение: Print line?

Hi,

is there an SQL command that just prints a line? I want to do sth like:

-- SQL query
print "Now displaying cities...";
SELECT * from cities;

By definition SQL doesn't have any output formatting
functions; those are provided by individual client
applications.

In psql you can use \echo to print a line to standard
output. \? shows other available options.

Try \qecho:


\qecho Now displaying cities
SELECT * FROM cities;

Otherwise you could also do:

\t
SELECT 'Now displaying cities...';
\t
SELECT * FROM cities;
