[GENERAL] psql \echo strangeness with :variables
Hello. Today I used a shell call in psql to save the runtime date in a psql variable and use this to dynamically create tables with date encoded in table name. For some reason however, the psql \echo command can't expand the date though it does expand in the calls to the backend. See example below; [EMAIL PROTECTED] = \set date `date '+%Y%m%d'` [EMAIL PROTECTED] = \echo :date 20060524 [EMAIL PROTECTED] = \echo foo_:date foo_:date <-- Was expecting this to expand... see below [EMAIL PROTECTED] = create table foo_:date(); CREATE TABLE [EMAIL PROTECTED] = \dt List of relations Schema | Name | Type | Owner +--+---+-- public | foo_20060524 | table | jsievers (1 row) Seems there's a bit of asymmetry in the way psql evaluates the :variables.
