CSS Universal Styles

to css html by rocketlaura on Sep 02, 2010
Start out a site's CSS with these, to level the playing field as much as possible.

/* remove all margins and padding */
* {
	margin: 0px;
	padding: 0px;
}
/* remove borders from any images that have links around them */
img {
	border:none;
}

/* remove default cellspacing and cellpadding, and set a width */
table {
  border-collapse: collapse;
  width:100%;
} 

/* all table cells align to top (not middle) and header cells to left */
td, th {
	vertical-align:top;
	text-align:left;
}

XSL creating nested elements

to XSL by rocketlaura on Sep 01, 2010
When I start with a fairly flat XML structure (several sets of elements not nested), here's the XSL to nest them. The example starts out with a set of <question> elements and <answer> elements, and nests the answers within the appropriate questions.

<xsl:template match="//question">
<question>
	<xsl:copy-of select="*"/>
	<xsl:apply-templates select="//answer[question_id = current()/id]"/>
</question>
</xsl:template>
<xsl:template match="//answer">
<answer>
	<xsl:copy-of select="*"/>
</answer>
</xsl:template>

MySQL using group and group_concat

to mysql sql by rocketlaura on Sep 01, 2010
// description of your code here

/* group by */
SELECT department, SUM(sales) AS total_sales
FROM order_details
GROUP BY department;

/* group_concat */
SELECT GROUP_CONCAT(popname ORDER BY popname ASC SEPARATOR ', ')

/* group_concat as aggregate function with group by:
SELECT state, GROUP_CONCAT(city) AS cities
FROM bigcities
GROUP BY state;

MySQL duplicating a table for testing

to mysql sql by rocketlaura on Sep 01, 2010
Here’s a maxim worth remembering when you feel the itch to run queries on a production database table: Duplicate the table you want to play with. The MySQL syntax for this command is simple.

/* this duplicates the table and all data in it */
CREATE TABLE new_table SELECT * FROM old_table;

/* this duplicates only a portion of the data, for testing */
CREATE TABLE new_table 
SELECT * FROM old_table WHERE field1='value' LIMIT 0, 10000;
