From: thuejk at gmail dot com Operating system: Linux PHP version: 5.2.9 PHP Bug Type: PostgreSQL related Bug description: pg_copy_from: WARNING: nonstandard use of \\ in a string literal
Description: ------------ Whenever I use pg_copy_from() I get an error in /var/log/postgresql/postgresql-8.3-main.log : 2009-03-12 19:43:12 CET WARNING: nonstandard use of \\ in a string literal at character 82 2009-03-12 19:43:12 CET HINT: Use the escape string syntax for backslashes, e.g., E'\\'. This is caused by pg_copy_from(), which in pgsql.c does something like the following: spprintf(&query, 0, "COPY \"%s\" FROM STDIN DELIMITERS '%c' WITH NULL AS '%s'", table_name, *pg_delim, "\\\\N"); If I pass the optional custom NULL indicator arg to pg_copy_from, ie replace "\\\\N" with for example "NULL", then the error goes away. Reproduce code: --------------- pg_query($db->connection, "CREATE TABLE test(a INT)"); pg_copy_from($db->connection, "test", Array(1)); -- Edit bug report at http://bugs.php.net/?id=47639&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47639&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47639&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47639&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47639&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47639&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47639&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47639&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47639&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47639&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47639&r=support Expected behavior: http://bugs.php.net/fix.php?id=47639&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47639&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47639&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47639&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47639&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47639&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47639&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47639&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47639&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47639&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47639&r=mysqlcfg
