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: daysdifference

function daysDifference($endDate, $beginDate){
$date_parts1=explode("-", $beginDate);
$date_parts2=explode("-", $endDate);

$start_date=@gregoriantojd($date_parts1[1], $date_parts1[2], $date_parts1[0]) or die('ERR #2342342a3: '.$date_parts1[1].' - '.$date_parts1[2].' - '.$date_parts1[0]);
$end_date=gregoriantojd($date_parts2[1], $date_parts2[2], $date_parts2[0]);
$diff = $end_date - $start_date;
return $diff;

//$years = floor($diff / (365.25*60*60*24));
//return $years;
}

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 };
}
