I am pulling all of the column_names (cname1) from a crosstab table that I made. There are thousands of these column names so I combined them into an array. I then want to use dynamic sql (or whatever works) to use those column_names to make an array based off of the records of that same crosstab table. I keep getting the error:
ERROR: missing "LOOP" at end of SQL expression
.
CREATE OR REPLACE FUNCTION mffcu.test_ty_hey()
RETURNS setof record
LANGUAGE plpgsql
AS $function$
Declare
cname1 text;
Begin
for cname1 in select array_agg(column_name) as useme
from(
select column_name::text
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'crosstab_183'
and ordinal_position != 1
) as fin
join mffcu.crosstab_183 a on fin.id = a.id;
loop
sql2 ='select distinct array['|| columnname ||'] from mffcu.crosstab_183';
execute sql2;
end loop;
END;
$function$
I cannot for the life of me figure out why I'm getting this error.
