Equivalent to mysql regex - mysql

Question

Mysql regex equivalent for this pattern:
<table (.+)width:(.+)px
I tried putting this pattern in my query but it will still hit items that doesn't have the pattern.
I use this site to check if the item hits that pattern above:

This is my query:
select * from wp_posts where post_content regexp '<table (.+)width:(.+)px';
This is the my sample post_content that is correct:
<table class="table-schedule" style="width: 737px;">
<tbody>
<tr>
<th>営業時間</th>
<th>月</th>
<th>火</th>
<th>水</th>
<th>木</th>
<th>金</th>
<th class="holiday">土</th>
<th class="holiday">日</th>
<th class="holiday">祝</th>
</tr>
<tr>
<td>11:00～19:00</td>
<td class="weekday maru">○</td>
<td class="weekday maru">休</td>
<td class="weekday maru">○</td>
<td class="weekday maru">○</td>
<td class="weekday maru">○</td>
<td class="holiday">○</td>
<td class="holiday">○</td>
<td class="holiday">○</td>
</tr>
</tbody>
</table>
This is the other sample post_content that is wrong. That will still hit even though there's no width on the table:
<table class="table-schedule">
<tbody>
<tr>
<th>営業時間</th>
<th>月</th>
<th>火</th>
<th>水</th>
<th>木</th>
<th>金</th>
<th class="holiday">土</th>
<th class="holiday">日</th>
<th class="holiday">祝</th>
</tr>
<tr>
<td style="text-align: center;">
<p>11:00～19:00</p>
</td>
<td class="weekday maru" style="text-align: center;">○</td>
<td class="weekday maru" style="text-align: center;">休</td>
<td class="weekday maru" style="text-align: center;">○</td>
<td class="weekday maru" style="text-align: center;">休</td>
<td class="weekday maru" style="text-align: center;">○</td>
<td class="holiday" style="text-align: center;">休</td>
<td class="holiday" style="text-align: center;">休</td>
<td class="holiday" style="text-align: center;">休</td>
</tr>
<tr>
<td style="text-align: center;">
<p>11:00～17:00</p>
</td>
<td style="text-align: center;">休</td>
<td style="text-align: center;">○</td>
<td style="text-align: center;">休</td>
<td style="text-align: center;">○</td>
<td style="text-align: center;">休</td>
<td style="text-align: center;">○</td>
<td style="text-align: center;">休</td>
<td style="text-align: center;">休</td>
</tr>
</tbody>
</table>
Note: mysql version 5.6

Answer 1

While your current regex pattern is valid, it won't behave the way you want, because the (.+) terms might match across tags. Try this version:
SELECT *
FROM wp_posts
WHERE post_content REGEXP '<table [^>]+width: [0-9]+px';
