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
