This will not look in other schema's, only the schema's in your search path. You can temporarily change this behavior with the following code:
pg_query($conn, "SET search_path TO myschema;");
$copy_from = pg_copy_from($conn, 'tablename', $filetoarray, ",");
if ( !$copy_from )
(PHP 4 >= 4.2.0, PHP 5)
pg_copy_from — Insert records into a table from an array
pg_copy_from() inserts records into a table from rows . It issues a COPY FROM SQL command internally to insert records.
PostgreSQL database connection resource.
Name of the table into which to copy the rows .
An array of data to be copied into table_name . Each value in rows becomes a row in table_name . Each value in rows should be a delimited string of the values to insert into each field. Values should be linefeed terminated.
The token that separates values for each field in each element of rows . Default is TAB.
How SQL NULL values are represented in the rows . Default is \N ("\\N").
Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.
Пример #1 pg_copy_from() example
$db = pg_connect("dbname=publisher") or die("Could not connect");
$rows = pg_copy_to($db, $table_name);
pg_query($db, "DELETE FROM $table_name");
pg_copy_from($db, $table_name, $rows);
- pg_copy_to() - Copy a table to an array
see also: pg_put_line for a solution that does not require buffering of all the data to be copied,
pg syntax is :
COPY test (cola, colb, colc) FROM stdin;
this function doesn't let you in which order the columns are !
By default NULL values are a backslash followed with capital N ("\\N").
Also, you can't insert entries with OIDs (I've added it to my TODO list though)
Something needs to be said about the format of the array.
Judging by what I've seen, it's pretty much what you get
from loading a tab-separated file with file(). That is, the
lines are linefeed-terminated and there's no need to have
an extra line with "\.". On the other hand, when I try using this
command the connection to the server ends up in some odd
state and is then lost:
PHP Warning: U�S�o() query failed: server closed the connection unexpectedly
I think it might be safer to use the lower-level function
pg_put_line() for now.
For starters, you can check the first line of every function document. It tells the minimum versions of PHP that you need in order to use the function.
