我想使用PHP pg_query_params方法将一个unix时间戳值插入postgres时间戳列,但是卡住了。
这里是不完整的代码:
$con = pg_connect(...);
$stmt = 'INSERT INTO my_table (submitted) VALUES ($1)';
$ts = 1479939387;
$values = [translate_timestamp_into_sth_postgres_accepts($ts)];
$res = pg_query_params($con, $stmt, $values);
问:如何将unix秒值转换为sth。 postgres接受了?
答案 0 :(得分:1)
使用函数to_timestamp(double precision)
:
select to_timestamp(1479939387) at time zone 'utc' as tstamp;
tstamp

您的代码可能如下所示(使用默认时区):
$con = pg_connect(...);
$stmt = 'INSERT INTO my_table (submitted) VALUES (to_timestamp($1))';
$ts = 1479939387;
$res = pg_query_params($con, $stmt, $ts);
