Hi guys, I've got tableA with 3 columns.
id(seriaL) | type(character varying(256)) | string(character varying(256)) I have the type/string value stored in another table, and from that i would like to get the id. Example: http://dbfiddle.uk/?rdbms=postgres_9.6&fiddle=15c571caa36876f00a0a2eaace703a2b How can I extract, from that tablea.type_m column the tableb.id value? Thanks Patrick
