From: Pavel Stehule on 4 Jul 2010 02:41 Hello I enhanced DO statement syntax to allowing a parameters. Syntax is relative simple: do ([varname] vartype := value, ...) $$ ... $$ It allows to pass a content of psql variables to inline code block to allows more easy scripting \set schema 'public' do(text := :'schema') $$ declare r record; begin for r in select * from information_schema.tables where table_schema = $1 loop raise notice '>>> table %', r.table_name; end loop; end $$; NOTICE: >>> table t NOTICE: >>> table t1 DO ToDo: * doesn't allows SubLinks :( pavel(a)postgres:5432=# do(text := (SELECT :'schema')) $$ declare r record; begin for r in select * from information_schema.tables where table_schema = $1 loop raise notice '>>> table %', r.table_name; end loop; end $$; ERROR: XX000: unrecognized node type: 315 LOCATION: ExecInitExpr, execQual.c:4868 ideas, notes, comments?? Regards Pavel Stehule
