Manual talk:Page table

I'm trying to access the information but I get an error when I place something in the Page_Title spot

wiki_page_title = 'Mrs._Harford' Cannot execute the query: Unknown column 'Mrs._Harford' in 'where clause'

What could be causing this?

if (! $thiscontent = mysql_query('SELECT old_text from wiki_page, wiki_revision, wiki_text where page_title = "Mrs._Harford" and page_latest = rev_id and rev_text_id = old_id')) { die("Cannot execute the query: ".mysqlerror); } else {echo $thiscontent;}

I figured that the quotes were causing problems, but now I only get Resource Id #3

quotes
when you ask for »"Mrs._Harford"«, you're actually asking for a column named literally »Mrs._Harford«. this is the effect of double quoting: protecting the content from further interpretation.

what you want is the value »Mrs._Harford«, a string typed value. the way to tell this to the sql parser is by using single quotes: »'Mrs._Harford'«.

obviously, since you are writing this in a string being delimited by single quotes itself, you must escape them.

an other way (a good practice) would be to use double quotes to delimit sql commands.

your text would then look like this:

if (! $thiscontent = mysql_query("SELECT old_text from wiki_page, wiki_revision, wiki_text where page_title = 'Mrs._Harford' and page_latest = rev_id and rev_text_id = old_id")) { die("Cannot execute the query: ".mysqlerror); } else {echo $thiscontent;}

Moved from page during rewrite

To get e.g. the current wikitext of a given page in the main namespace: SELECT LEFT(old_text,1024) FROM page INNER JOIN revision ON page_latest = rev_id INNER JOIN text ON rev_text_id = old_id WHERE page_title = 'Your page title' AND page_namespace=0; Note: The use of LEFT(old_text,1024) allows the first 1024 characters to be printed because, old_text being a blob, your query would probably only display "[BLOB -  .  KiB]" where  .  is the size in kilobytes of your page content. If you are using this query in a program and need the entire content in old_text, be sure to only reference old_text and not LEFT(old_text,1024).
