Hello all,
I am writing an app in PHP that uses a PostGres database.
One thing i have noticed is that what should/could be a single line of
SQL code takes about 6 lines of PHP. This seem wasteful and redundant
to me.
Here is a sample of what I'm talking about ($db is a PDO already
defined and created).
$query[1] = "UPDATE my.table, SET somefield = '$someval' WHERE
somecondition";
$query[2] = "INSERT INTO my.table (somefield) VALUES ('$someval')";
if(!$db->query($query[1])){
$db->query($query[2]);
}
What I'm curious to know is if there is some way to simplify this,
either buy some PHP builtin or extension, or possibly something in SQL
I am missing. It seems to me that "UPDATE OR INSERT", should be valid,
but I can't seem to find anything relevant at all about it.
Anyways I hope you don't mind, but I'm crossposting this to
pgsql.general and comp.lang.php to see if I can get some information on
the subject.

Just for the record, Postgres supports "CREATE RULE". One does not have
to spend thousands of dolars for that.

I have a scenario where two tables are in a One-to-Many relationship

I need to salvage the records from the many table and without going
into detail, one of the reasons I can't do the opposite as
there are records in the ONE table that I need to keep even if they
don't have any child records in the MANY table.

I want to be able to generate SQL statements that will go through a list of
data, effectively row by row, enquire on the database if this exists in the
selected table- If it exists, then the colums must be UPDATED, if not, they
must be INSERTED.
Logically then, I would like to SELECT * FROM <TABLE>
WHERE ....<Values entered here>, and then IF FOUND
UPDATE <TABLE> SET .... <Values entered here> ELSE
INSERT INTO <TABLE> VALUES <Values...

been ruminating on the question (mostly in a 390/v7 context) of
whether, and if so when, a row update becomes an insert/delete.
i assume that there is a threshold on the number of columns of
the table, or perhaps bytes, being updated where the engine just
decides, screw it, i'll just make a new one.
surfed this group and google, but couldn't find anything.

Hello,
I have created 3 functions to insert, update and delete an Access
database record. The Insert and the Delete code are working fine.
The update is not. I checked and my database has all the necessary
records in it when testing it. I get the error "No value given for one
or more required parameters." when I try to update the database.
Can you tell me what am I doing wrong?

So I have some data that I want to put into a table. If the
row already exists (as defined by the primary key), I would
like to update the row. Otherwise, I would like to insert
the row.
I've been doing something like
delete from foo where name = 'xx';
insert into foo values('xx',1,2,...);

Hello all,
SQL Server 2000 documentation
http://www.microsoft.com/technet/prodtechnol/sql/2000/reskit/part10/c3761.mspx
states that if view is using "NOT NULL" columns of a base table, then
insert/update performed on a view must provide dummy values for those
columns, and code of the trigger should ignore them.
But I cannot reproduce this restriction. Code below pasted to QueryAnalyser
shows that I can not supply dummy values for...
