Hi list,
My google skills are very poor, so excuse me if this is
documented some place I'm failing to find.
I started to look into using pg_query_params() with some
php scripts, but ran into this issue where I get:
PHP message: PHP Warning: pg_query_params(): Query failed: ERROR:
invalid input syntax for type timestamp: "$1"
LINE 1: ... date_trunc('day', now()), date_trunc('day', TIMESTAMP '$1')
(excuse typos if any -- I'm hand-typing from a different screen).
The test query is a simple
SELECT date_trunc('day', now()),
date_trunc('day', TIMESTAMP '2014-05-16 21:00:00');
where the '2014-05-16 21:00:00' is an input parameter.
Trying with pg_query_params() fails as mentioned:
$s = "2014-05-16 21:00:00";
$res = pg_query_params($db,
"SELECT date_trunc('day', now()), "
."date_trunc('day', TIMESTAMP '" . '$1' . "')",
array($s));
If I remove the single quotes for TIMESTAMP the syntax
error message changes to:
Query failed: ERROR: syntax error at or near "$1"
LINE 1: ... date_trunc('day', now()), date_trunc('day', TIMESTAMP $1)
while the pg_query() method works as expected:
$sql = sprintf("SELECT date_trunc('day', now()), "
."date_trunc('day', TIMESTAMP '%s')",
pg_escape_string($db, $s));
$res = pg_query($db, $sql);
Where is the bug? my code? my understanding of how
this is supposed to work? in pg_query_params()?
Best,
--patrick
