pg_copy_to — 将一个表拷贝到数组中
$connection
, string $table_name
[, string $delimiter
[, string $null_as
]] ) : array
pg_copy_to() 将一个表拷贝到数组中，该数组作为结果返回。它在内部使用了 COPY FROM SQL 命令来插入记录，并返回结果数组。如果失败则返回 FALSE。
参见 pg_copy_from()。
You cannot specify the schema name in this command. You can change the search path for just one query by using the following code:
<?php
pg_query($conn, "SET search_path TO myschema;");
$copy_to = pg_copy_to($conn, 'tablename');
pg_query("RESET search_path;");
?>
"It issues COPY TO SQL command internally to insert records"
I suspect this statement is incorrect, or that s/insert/retrieve/ is appropriate.
