postgresql-9.1

In PostgreSQL, I would like to store signed values -999.9 - 9999.9 . Can I use numeric(5.1) for this? Or what type should I use? Erwin Brandstetter You can certainly use the arbitrary precision type numeric with a precision of 5 and a scale of 1, just like @Simon commented , but without the syntax error. Use a comma( , ) instead of the dot ( . ) in the type modifier: SELECT numeric(5,1) '-999.9' AS nr_lower , numeric(5,1) '9999.9' AS nr_upper; nr_lower | nr_upper ----------+---------- -999.9 | 9999.9 The minus sign and the dot in the string literal do not count against the allowed maximum of

This sounds like it should be a very easy thing to do, however, I cannot find ANYWHERE how to do it. I have a .sql file I am building for an upgrade to my application that alters tables, inserts/updates, etc. I want to write to the screen after every command finishes. So, for instance if I have something like: insert into X... I want to see something like, Starting to insert into table X Finished inserting into table X Is this possible in Postgres? If you're just feeding a big pile of SQL to psql then you have a couple options. You could run psql with --echo-all : -a --echo-all Print all input

I am new to postrges and want to sort varchar type columns. want to explain the problem with with below example: table name: testsorting order name 1 b 2 B 3 a 4 a1 5 a11 6 a2 7 a20 8 A 9 a19 case sensitive sorting (which is default in postgres) gives: select name from testsorting order by name; A B a a1 a11 a19 a2 a20 b case in-sensitive sorting gives: select name from testsorting order by UPPER(name); A a a1 a11 a19 a2 a20 B b how can i make alphanumeric case in-sensitive sorting in postgres to get below order : a A a1 a2 a11 a19 a20 b B I wont mind the order for capital or small letters,

I am having day and time fields in database. I want to get the time-stamp by concatenating the day and time. How to do this in PostgreSQL? I have done this: SELECT EXTRACT(EPOCH FROM TIMESTAMP '2011-05-17 10:40:28'); And it is working fine. But when I tried replacing day and time fields I am getting the following error: SELECT EXTRACT(EPOCH FROM TIMESTAMP Day || ' ' || Time); ERROR: syntax error at or near "Day" LINE 1: ...quest_count > 0 AND (EXTRACT(EPOCH FROM TIMESTAMP Day || ' ' || Time)) > (e...

I want to use SELECT INTO to make a temporary table in one of my functions. SELECT INTO works in SQL but not PL/pgSQL. This statement creates a table called mytable (If orig_table exists as a relation): SELECT * INTO TEMP TABLE mytable FROM orig_table; But put this function into PostgreSQL, and you get the error: ERROR: "temp" is not a known variable CREATE OR REPLACE FUNCTION whatever() RETURNS void AS $$ BEGIN SELECT * INTO TEMP TABLE mytable FROM orig_table; END; $$ LANGUAGE plpgsql; I can SELECT INTO a variable of type record within PL/pgSQL, but then I have to define the structure when
