Обсуждение: Looking for help

I am new to combining PHP and Postgres. I am able to Select and create
tables by using the Select * From "table" command fine, but What happens
if I only want to select a couple of fields. How do I go about this.
also how do you select from a table that is not all lower case. Granted
this is probably quite simple, but I am new to this. thanks ewveryone

 Use quotes around the field and table names that are not all lower case:

Ex:
$result = pg_query($db," Select 'Field1',field2, 'fEild3' From'TABLE1' ");

TIP 5: Have you checked our extensive FAQ?

Hi Joseph

Then you tell the server which fields you want to select;-)

SELECT field1, field2, ... , fieldn FROM table ...

> how do you select from a table that is not all lower case
what do you mean? what is not all lower case?
PostgreSQL returns the contents of the fields as they are. If you need
the results to be in lower case use
SELECT lower(fieldx), lower(field2),... FROM table
respectively
SELECT upper(field1), upper(field2), ... FROM table.

See chapter 4.4 of the PostgreSQL user's Guide for more.

The PHP-Functions to change case are strtoupper() and strtolower().

Hope it helps

AFAIK, opstgres needs double quotes to handle objects' names literally
-- as written:

$result = pg_query($db,' Select "Field1",field2, "fiEld3"
 From "TABLE1"');

text within simple quotes represents string literals.

Table and column names are not case-sensitive in Postgres.
