Re: store key name pattern search

Thank you Jeff 

Nice . I also looked at  akeys/skeys 

My goal is to get the key by pattern matching and then passing it back like in col1->key

Hi

I have the following case


select * from foo;
                                      col1
---------------------------------------------------------------------------------
 "show_id"=>"1", "group_id"=>"32", "group_name"=>"slb", "group_add_by"=>"557651"
 "show_id"=>"2", "group_id"=>"33", "group_name"=>"slc", "item_add_by"=>"557652"
(2 rows)

Is there anyway I can do a pattern search by hstore key name something like

select * from foo where skeys(col1) like '%add_by%';

I looked on the doc but did not see anything , or did I miss it ?

select * from foo where array_to_string(akeys(x),';') like '%add\_by%';

Note that I back-slashed the underscore, otherwise it acts as a wildcard and may match more than you bargained for.

Cheers,

Jeff
