• PostgreSQL or MS SQL Server?

  - by mmiika

  I'm considering using PostgreSQL with a .Net web app. Basically 3 reasons: Mature Geo Queries Small footprint + Linux Price I'm wondering a bit about tools though, SQL Server Profiler and query plans and performance monitors have been helpful.

• Basic SQL Select in Postgresql fails

  - by Rhubarb

  I am doing a select * on a postgresql table, and everything looks good. But if I do: SELECT Name from People It says: ERROR: column People.Name does not exist SQL state: 42703 Character: 8 But the name column shows up during select *. I've tried: SELECT People.Name from People as well, with the same result. Am I missing something? It should be pretty easy to do this in any other database.

• postgresql drop table

  - by Russell

  I have two tables (tbl and tbl_new) that both use the same sequence (tbl_id_seq). I'd like to drop one of those tables. On tbl, I've removed the modifier "not null default nextval('tbl_id_seq'::regclass)" but that modifier remains on tbl_new. I'm getting the following error: ERROR: cannot drop table tbl because other objects depend on it DETAIL: default for table tbl_new column id depends on sequence tbl_id_seq After reviewing http://www.postgresql.org/docs/9.1/static/sql-droptable.html It looks like there is only CASCADE and RESTRICT as options.

• No getdate() function in Enterprise PostgreSQL

  - by Suezy

  Hi guys, do you have any idea on how to have getdate() function in enterprise postgresql? I upgraded to EDB-PSQL, and now when I tried to restore old data from the free PSQL, it returns error on some tables since there is no getdate(). I believe this should automatically be created upon creating new database? But it didn't. :( Only now() function. Can I create the function instead? Help!
