我有一個WordPress的MySQL數據庫我試圖從perl的DBD :: mysql中提取一些數據。Perl DBD :: mysql從longtext字段中剔除單詞
如果我這樣做,在命令行:
mysql --raw mydb <<EOF
select post_content from wp_posts where ID = 195;
EOF
我得到了我期待......這裏是前兩句:
I guess someone famous enough to have <a
href="http://en.wikipedia.org/wiki/Hee_Il_Cho" target="_blank">his own
Wikipedia page</a> is worth anyone's consideration. I'm not familiar
with AIMAA, but they appear to have quite a few affiliated school
(particularly in the UK).
但如果我這樣做在Perl:
$dsn = "DBI:mysql:database=$dbname";
$dbh = DBI->connect($dsn, $dbuser, $dbpass);
$sql_page_list = $dbh->prepare ("
SELECT post_title, post_content
FROM wp_posts
WHERE post_status = 'publish'
AND post_type = 'page'
ORDER BY post_title
");
$sql_page_list->execute();
while ($prog_row = $sql_page_list->fetchrow_hashref) {
print $prog_row->{post_content} . "\n";
...
我得到:
I guess someone famous enough to have <a
href="http://en.wikipedia.org/wiki/Hee_Il_Cho" target="_blank">his own
Wikipedia page</a>worth anyone's consideration. not familiar with
AIMAA, but they appear to have quite a few affiliated school
(particularly in the UK).
這裏是所缺單詞相同的文字註明:
I guess someone famous enough to have <a
href="http://en.wikipedia.org/wiki/Hee_Il_Cho" target="_blank">his own
Wikipedia page</a> **is** worth anyone's consideration. **I'm** not
familiar with AIMAA, but they appear to have quite a few affiliated
school (particularly in the UK).
任何想法可能會導致什麼? post_content是長文本。 table_collation是utf8_general_ci。
這種模式貫穿整個文本 - 單詞缺失。它發生在所有的帖子上。
您執行這兩個查詢是不同的。我並不是說這就是問題所在,只是如果您對兩者使用完全相同的查詢,它可以使故障排除更容易。 – ThisSuitIsBlackNot
