Thanks Guy, is it possible to get the 3rd column result as an array
instead of string? -Nick

tbh, your solution using array_agg over union all upthread looked spot on...

Sure, did you look in the documentation?
select
t3.id,
coalesce
(
t1.title,
t2.title,
t3.title
),
string_to_array(coalesce
(
case
when t1.title is not null
then 'table_one,'
else null
end,
case
I guess I should mention that im basically searching for a way to
recusively coalesce the title. So I want to search the second table
and
table_one (id,title)
1 | new one
table_two (id,title)
2 | new two
table_three (id,title)
1 | one
2 | two
3 | three
Id like an sql statement that returns...
Is it possible to get the results of this snip of a function without
using a function? All tables include an id and title column.
tables := ARRAY[table_one,table_two,table_three]::VARCHAR;
CREATE TEMP TABLE final_results (id INTEGER, title VARCHAR, r_types
VARCHAR[]);
FOR t IN
Found a solution for what I need. Please let me know if you know of
something better/faster. -Nick
CREATE AGGREGATE array_accum (anyelement) (
sfunc = array_append,
stype = anyarray,
initcond = '{}'
);
SELECT id, title, array_accum(t) AS ts FROM (
SELECT 'table_one' AS t, id, title
Sure:
select
t3.id,
coalesce
(
t1.title,
t2.title,
t3.title
),
coalesce
(
case
when t1.title is not null
then 'table_one,'
else null
end,
case
when t2.title is not null
then 'table_two,'
