Why must an array have an even number of elements? I need to use a
trigger function on any table, some of which may have an odd number of
columns that I want to cleanse before inserting/updating.
Is there a workaround for this?
ERROR: array must have even number of elements
SQL state: 2202E
Context: SQL statement "SELECT ($1 #=
hstore(array[trim(replace(regexp_replace($1.c,'( ){2,}',' ','g'),' ','
')),trim(replace(regexp_replace($1.vc,'( ){2,}',' ','g'),' ','
')),trim(replace(regexp_replace($1.t,'( ){2,}',' ','g'),' ',' '))])).*"
PL/pgSQL function store.trim_string_before_dml() line 44 at EXECUTE
-- my test table
create table dm.trg_test (c character(8), vc varchar(16), t text);
insert into dm.trg_test (c,vc,t) values ('ctest',' vctest ','
ttest ');
-- code snippet that produced the error.
-- new will be substituted for $1 during execution with using clause
l_query_string := 'select ($1 #= hstore(array[' || l_column_list ||
'])).*';
execute format(l_query_string) using new into new;
return new;
Thanks for your help!
