Each function returns key/value pairs from hstore type. Is there any opposite function that returns hstore type from key/value rows?
I know hstore (text[], text[]) can construct it. Is there any other choice? I have a table with ID & Description columns and want to return hstore type (ID1=>Desc1,ID2=>Desc2,....) that matches a query condition. >From top of my head, this is the only query I can think of SELECT hstore ((SELECT array(SELECT CAST(ID as TEXT) FROM T1 WHERE ....)), (SELECT array(SELECT Description FROM T1 WHERE ...))) But I don't want to run the same where condition twice. If I can construct a single array (K1, V1, K2, V2, ...) from key/value rows, then I can use hstore(text[]) function. Of course, I can create a stored function that loops through the rows and construct it, that's the last resort and I don't like that approach. Any idea? Thank you, Choon Park
