Hi, I am trying to setup partitions and as a test, I was able to follow the example in the Postgres docs using the date as a condition. Now I am trying to partition on a column with the data type character varying. I want to partition based on an invoice ID consisting on letters and numbers like I-10, I-11. I create my function: IF ('invoice' <= 'I-10000') THEN INSERT INTO myschema.mywork VALUES (NEW.*) ELSE IF ('invoice' >= 'I-10001' AND <= 'I-20000') THEN INSERT INTO myschema.mywork VALUES (NEW.*) ELSE RAISE EXCEPTION... Is it possible to perform this type of operation with a mix of letters and numbers? So far any attempts to insert based on these conditions raises the exception. Thanks. -- View this message in context: http://postgresql.nabble.com/Partition-Help-tp5847235.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
