Обсуждение: store key name pattern search
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 ? Thanks Armand

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,

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
