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@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??
