Yes, I have read that documentation. I have other queries in this
same program with a similar structure that do work. One of these is
as follows:
$pg_pres_ins4 = pg_query_params("INSERT INTO \"brdgPresenters
\" (\"peopleId\",\"presentationEventId\") VALUES ($1,
currval('\"brdgPresentationsEvents_presentationEventId_seq
\"'))",array($choose_name));
The above query works fine.
Part of the problem is that the currval function requires that the
parameter be enclosed in single quotes. Because the person who created
this database used the upper-lower case naming convention, postgres
requires the datanames be inclosed in double quotes. I can either
enclose the whole query in single or double quotes, but either way one
of them will have to be escaped when using the currval function. I
don't know if that's where the problem lies, but it certainly
complicates the query more that it needs to be.
According to /www.postgresql.org/docs/8.3, the syntax is as follows:
nextval('foo') operates on sequence foo
nextval('FOO') operates on sequence foo
nextval('"Foo"') operates on sequence Foo
currval is analogous to nextval but works on the current value of the
sequence and not the next value of the sequence. The third form is
what I have to use because of the upper-lower case thing. I also
tried the "returning" clause on my insert query, but that doesn't seem
to work either.
Thanks,
Carol

Hello,
I'm using PHP 5 and PostgreSQL 8.3.6. I have a query that is
failing and I don't know how to troubleshoot the problem. The
error message that it is giving is quite vague. The error message
is as follows:
Warning: pg_query_params() [function.pg-query-params]: Query
failed: ERROR: syntax error at end of input at character 156 in /
home/walterc/ssl/PHP/km_input_test2c.php on line 631
ERROR: syntax error at end of input at character 156
The query that is failing looks like this...
$pg_pres_ins6 = pg_query_params("INSERT INTO \"brdgMediaCallsEvents
\" (\"mediumId\", \"eventId\", rank) VALUES
((currval('\"tblMedia_mediumId_seq\"'),
(currval('\"tblCallsEvents_eventId_seq\"'), $1)", array($ev_rank));
echo pg_last_error($pg_connection);
Whoops, ignore the last one I forget a single quote after the actual
sql string
Perhaps try:
$pg_pres_ins6 = pg_query_params( $pg_connection, 'INSERT INTO
`brdgMediaCallEvents` ( `mediumId`, `eventId`, `rank` ) VALUES
( \"val1\", \"val2\", \"val3\" )', array( "ev_rank" ) );
You need to read the document for this function because it looks
like you were mis-using it.
http://us3.php.net/manual/en/function.pg-query-params.php
It's quite possible this is something very simple and I'm just not
seeing it. I commented out this query because I thought perhaps
it was failing because it was the last query in the program. The
previous query did not fail when it became the last one.
Thanks in advance for your help.
