ID: 41146 Updated by: tony2001@php.net Reported By: shade at nekto dot com -Status: Open +Status: Assigned -Bug Type: PostgreSQL related +Bug Type: Feature/Change Request Operating System: Windows, FreeBSD PHP Version: 5.2.1 -Assigned To: +Assigned To: yohgaki Previous Comments: ------------------------------------------------------------------------ [2007-04-20 08:27:42] shade at nekto dot com Description: ------------ I found that pg_meta_data do not returns fields descriptions in result. I explore sources and found that table's meta fteched by query, citated below. I do not have free FreeBSD host for programming experiments, but i upgrade a query little bit, adding ability to fetch description from fields. Can you use my query to add to pg_meta_data() ability to return field descriptions? Reproduce code: --------------- Original code: smart_str_appends(&querystr, "SELECT a.attname, a.attnum, t.typname, a.attlen, a.attnotNULL, a.atthasdef, a.attndims " "FROM pg_class as c, pg_attribute a, pg_type t " "WHERE a.attnum > 0 AND a.attrelid = c.oid AND c.relname = '"); tmp_name = php_addslashes((char *)table_name, strlen(table_name), &new_len, 0 TSRMLS_CC); smart_str_appendl(&querystr, tmp_name, new_len); efree(tmp_name); smart_str_appends(&querystr, "' AND a.atttypid = t.oid ORDER BY a.attnum;"); smart_str_0(&querystr); Changed code, that i proposes: smart_str_appends(&querystr, "SELECT a.attname, a.attnum, t.typname, a.attlen, a.attnotNULL, a.atthasdef, a.attndims, d.description " "FROM pg_class as c JOIN pg_attribute a on (a.attrelid = c.oid) JOIN pg_type t on (a.atttypid = t.oid) " "LEFT JOIN pg_description d on (d.objoid=a.attrelid and d.objsubid=a.attnum and c.oid=d.objoid) " "WHERE a.attnum > 0 AND c.relname = '"); tmp_name = php_addslashes((char *)table_name, strlen(table_name), &new_len, 0 TSRMLS_CC); smart_str_appendl(&querystr, tmp_name, new_len); efree(tmp_name); smart_str_appends(&querystr, "' ORDER BY a.attnum;"); smart_str_0(&querystr); Expected result: ---------------- Information about table, including fields description (aka comments). Actual result: -------------- No any descriptions :( ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41146&edit=1
