Обсуждение: Table Names

I have a table name SYS_Keyword, but everytime I try to query it, postgres
converts it to sys_keyword and then can't find it.  Why does it do this
and is there any way around it?

Thanks

Rob

A table name is a SQL identifier; all identifiers are case-insensitive
unless they are enclosed in double quotes (").  So long as you are
consistent, there is no problem because all unquoted identifiers are
converted to lower case.

It seems that you must have created the table with quotes around its
name  CREATE TABLE "SYS_Keyword" (...) ; therefore you must always now
refer to it as "SYS_Keyword" in order to be able to find it.

In general it is a good idea not to try to mix case in identifiers; it
only leads to confusion.

Rob,

Search Google for 'postgres case sensitivity' for loads of links re this.

(in summary to keep case sensitivity use double quotes for object names in
your SQL)

AFAIK postgresql is case-insensitive and works internally with
lowercase characters. you could use double quotes but for table names,
that way the uppercase remains, but you would have to use the quotes
every time you use the table name.

Hi

I have a TABLE (say "test"). I want to write a trigger which shall generate
and send an Email.

Trigger fires for ROW or STATEMENT level. I want to send mail for bunch of
records and not for every insert.

Is there any way to FIRE TRIGGER FOR EVERY COMMIT and not for any DML ???

e.g.
BEGIN;
INSERT INTO test VALUES (1,'Denis');
INSERT INTO test VALUES (2,'Denis');
INSERT INTO test VALUES (3,'Denis');
COMMIT;

I want to send an email with following text (as body)
"User xxx has inserted 3 records as details below :
        1,Denis
        2,Denis
        3,Denis"

AS SINGLE EMAIL.


Thanx

Denis
