pg_copy_to — 将一个表拷贝到数组中

说明

pg_copy_to ( resource $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。

Worth noting here that just like the COPY TO statement in PostgreSQL, '$table_name' can include a list of columns or be a select query as well.

e.g.:

$rows = pg_copy_to($db,'schema."TableName" (column1, column2, ...)';

$rows = pg_copy_to($db,'(SELECT ...)');

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.
