SQL Coding Standards

Coding and Naming Standards:

On every project I've worked on, people have discussed coding & Naming Standards, but we always eventually realize that nobody has written these things down. So I have started these proposed standards:

• Names: like_this
• ID: Must be (INT) Named like: table_id

Coding Analogies

• Variable- Cooking ingredient
• Switch - Train switching station. or a choose your own adventure
• If - For in the road
• Break - Exit out of current Loop
• Exit (or Die)- Quit IMMEDIATELY, and print something to the screen

Regex GEdit:

Delete every other line.

([^\n]*\n)[^\n]*\n

Regex tester for Search AND Replace:

Make all Links open in a New Window jquery.

<script>$("#content a[href^='http://']").attr("target","_blank");</script>
<script>$("#content a[href^='https://']").attr("target","_blank");</script>

SQL Queries

Count all Table Rows

SELECT TABLE_NAME, TABLE_ROWS FROM `information_schema`.`tables` WHERE `table_schema` = "adamwith_main";

Hwo to assign an array to two variables

I always forget :P
list($first, $second)=array(1,2);

Geo IP Location:

You are in: Columbus, United States

My Commonly Used Functions:

View Function: getamazonpics

function getAmazonPics($query,$tag='LARGEIMAGE'){
//Tag Examples: LARGEIMAGE, MEDIUMIMAGE, SMALLIMAGE
//The First Image is probably the one you want
$signed_url = getQuerySignature($query);
//die('$signed_url: '.$signed_url);
/* Use CURL to retrieve the data so that http errors can be examined */
$ch = curl_init($signed_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 7);
$xml_string = curl_exec($ch);
$curl_info = curl_getinfo($ch);
curl_close($ch);
if($curl_info['http_code']!=200) {
return '

ERROR:

Check the $curl_info [below] to discover why AWS returned an error
$xml_string may still contain valid XML, and may include an informative error message'. var_export($curl_info,true);
}else {
//$debugArray = new SimpleXMLElement($xml_string);prettyArray($movies);die('a');
$p = xml_parser_create();
xml_parse_into_struct($p, $xml_string, $vals, $index);
xml_parser_free($p);
//echo "

Index array

\n"; print_r($index);
//echo "

Vals array

\n";print_r($vals);
$toReturn=array();
foreach($vals as $i=>$key){
if($key['tag']==$tag){//Get the NEXT Tag
if(isset($vals[$i+1]['value']) ){
$toReturn[]= $vals[$i+1]['value'];
}
}
}
}
return $toReturn;
}

Add a hyphen to lists when Copying & Pasting

const prependChar = "-";
document.addEventListener("copy", function(e) {
const selected = getSelectionHtml();
if (selected.html.includes("
")) {
const ul = selected.container.querySelectorAll("li");
Array.from(ul).forEach(c => {
if (c.tagName === "LI") {
c.innerText = prependChar + " $$$ " + c.innerText;
}
});
// Remove unwanted whitespace
const html = selected.container.innerHTML.replace(/(^|>)[ \n\t]+/g, ">\n"); 
const list = `
${html}
`;
const wrap = document.createElement("div");
wrap.innerHTML = list;
e.clipboardData.setData("text/plain", wrap.textContent);
e.clipboardData.setData("text/html", list);
e.preventDefault();
}
});
function getSelectionHtml() {
let html = "";
let container;
if (typeof window.getSelection !== "undefined") {
const sel = window.getSelection();
if (sel.rangeCount) {
container = document.createElement("div");
for (let i = 0, len = sel.rangeCount; i < len; ++i) {
container.appendChild(sel.getRangeAt(i).cloneContents());
}
html = container.innerHTML;
}
} else if (typeof document.selection !== "undefined") {
if (document.selection.type === "Text") {
html = document.selection.createRange().htmlText;
}
}
return { html, container };
}
