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

\1

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);

You are in: Columbus, United States

My Commonly Used Functions:

View Function: deletedirectory

function deleteDirectory($directoryToDelete,$limit=100,$notIn=array()){
$allThumbnailDirectories = glob($directoryToDelete.'/*'); // get all file names
if( in_array( $directoryToDelete, array('','.','..') ) ){
return; //end for safety
}
if(! isset($GLOBALS['deleteDirectoryLimit']) ){
$GLOBALS['deleteDirectoryLimit']=$limit;
}
if($GLOBALS['deleteDirectoryLimit']<=0){
//die('aaa');
$GLOBALS['deleteDirectoryLimit']=0;
return; //end
}
//echo 'deleteDirectory: '.$directoryToDelete.'----'.$GLOBALS['deleteDirectoryLimit'].'
';
foreach($allThumbnailDirectories as $eachFile){
//echo '........'.$eachFile.'
';
//echo 'is: '.$eachFile.' in ('.var_export($notIn,true) .')
';
//if( is_dir($eachFile) && (! in_array($eachFile,$notIn) ) ){Fix this one day
if( is_dir($eachFile) ){
//echo 'Calling deleteDirectory: '.$eachFile.'
';
deleteDirectory($eachFile,$GLOBALS['deleteDirectoryLimit']);
if(isDirectoryEmpty($eachFile) ){
$GLOBALS['deleteDirectoryLimit']--;
rmdir($eachFile); // delete directory, now that it is empty
}
}else if( is_file($eachFile)){
//echo 'Deleting '.$eachFile.'
';
$GLOBALS['deleteDirectoryLimit']--;
unlink($eachFile);// delete file
}
}
//once youre done, recreate these folders
}

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 };
}
