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 ...)');

"It issues COPY TO SQL command internally to insert records"

I suspect this statement is incorrect, or that s/insert/retrieve/ is appropriate.

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;");
?>
