I changed nothing! IF(l.last_comment_uid <> 0 AND l.last_comment_uid IS NOT NULL, cu.name, l.last_comment_name) patrickslee Previous comments: ------------------------------------------------------------------------ May 24, 2005 - 16:32 : cchamilt Postgresql function "if" is defined to return a boolean value, yet forum requests an integer - last_comment_uid. user error: query: SELECT n.nid, l.last_comment_timestamp, IF(l.last_comment_uid, cu.name, l.last_comment_name) as last_comment_name, l.last_comment_uid FROM node n, node_comment_statistics l /*!

You may need to add explicit type casts. in /var/www/hosts/www.ambigc.com/htdocs/includes/database.pgsql.inc on line 45. ------------------------------------------------------------------------ May 25, 2005 - 10:07 : patrickslee Attachment: http://drupal.org/files/issues/forum.module_3.patch (2.69 KB) I have also encountered this bug and made a possible patch by replacing IF statements to CASE. A patch file is attached. ------------------------------------------------------------------------ May 25, 2005 - 10:28 : adrian There is an IF function defined in the database.pgsql function. On what page is this happening, as what might be happening is that the type isn't being picked up correctly. It's defined as IF(anyelement, anyelement, text) returns anyelement. IIRC. What I have seen happen is that it wants the text field to return integer, or vice versa. ------------------------------------------------------------------------ May 25, 2005 - 10:32 : patrickslee I found the definition in database.pgsql. It is like this: CREATE FUNCTION "if"(boolean, anyelement, anyelement) RETURNS anyelement AS ' SELECT CASE WHEN $1 THEN $2 ELSE $3 END; ' LANGUAGE 'sql'; So it is actually wanting boolean. ------------------------------------------------------------------------ May 25, 2005 - 10:43 : patrickslee So my patch will work, and we can make it easier by replacing the IF function to: IF(l.last_comment_uid 0 AND l.last_comment_uid NULL, cu.name, l.last_comment_name) BTW there is another place in forum.module use IF like this. ------------------------------------------------------------------------ May 25, 2005 - 10:45 : patrickslee Oops... my <>s are stolen. IF(l.last_comment_uid <> 0 AND l.last_comment_uid <> NULL, cu.name, l.last_comment_name) ------------------------------------------------------------------------ May 25, 2005 - 17:20 : cchamilt Yes that line works great. Thanks for your help! ------------------------------------------------------------------------ May 25, 2005 - 17:52 : patrickslee This patch shows another problem. The last post user will always show "Anonymous" or whatever you defined. Looking for solution... ------------------------------------------------------------------------ May 25, 2005 - 18:00 : patrickslee Use this line instead: IF(l.last_comment_uid <> 0 AND l.last_comment_uid <> NULL, cu.name, l.last_comment_name) Don't forget there are two places in forum.module need to be changed.
