Re: Inserting Null Value or String Value

Actually, this does not work, it generates the SQL fine, but I get a Parse error when trying to insert it. I am doing something very similar, did I mess up somewhere.
Here is the PHP:
if ($special_start_date == '')
{$special_start_date = 'null';}
else {$special_start_date = "'$special_start_date'";}
if ($special_end_date == '')
{$special_end_date = 'null';}
else {$special_end_date = "'$special_end_date'";}
$sql = "INSERT INTO prod_opt (
xref_prod_id,
code,
title,
isbn,
list_price,
our_price,
spec_price,
spec_start_date,
spec_end_date,
quantity,
clearance,
priority)
VALUES (
'".$prod_id."',
'".$item_code."',
'".$option_format."',
'".$isbn."',
".$list_price.",
".$our_price.",
".$special_price.",
".$special_start_date.",
".$special_end_date.",
".$qty.",
'".$clearance."',
".$priority.")";
$result = pg_exec($dbh, $sql);
This is the error I get: Warning: PostgreSQL query failed: ERROR: parser: parse error at or near "10"
This is the SQL generated: UPDATE prod_opt SET xref_prod_id = '4', code = '2', title = 'test', isbn = '2', list_price = 2, our_price = 2, spec_price = 2, spec_start_date = '10/01/02', spec_end_date = '10/01/02', quantity = 2, clearance = 't', priority = 2 WHERE id = '2'

Maybe you should do the following. At the point where the switch
"date" or "NULL" in the php-file is:

if(empty($form_date)){
$date_var = NULL;
}else $date_var = "'$date'";

$query = "INSERT INTO table (table_row1, date)
VALUES ('$value1', $date_var);";

You still have the if/else, but I think there must be somewhere the
switch NULL <=> date
