Measures in SQL (SIGMOD 2024, Santiago, Chile)Julian Hyde
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

Hand Rolled Applicative User ValidationCode KataPhilip Schwarz
Could you use a simple piece of Scala validation code (granted, a very simplistic one too!) that you can rewrite, now and again, to refresh your basic understanding of Applicative operators <*>, <*, *>?
The goal is not to write perfect code showcasing validation, but rather, to provide a small, rough-and ready exercise to reinforce your muscle-memory.
Despite its grandiose-sounding title, this deck consists of just three slides showing the Scala 3 code to be rewritten whenever the details of the operators begin to fade away.
The code is my rough and ready translation of a Haskell user-validation program found in a book called Finding Success (and Failure) in Haskell - Fall in love with applicative functors.
Learning of Php and My SQL Tutorial | For Beginners
1. PHP & MySQLPHP & MySQL
WebsolesTraining MaterialWebsolesTraining Material
www.websoles.comwww.websoles.com
2. What is PHP Used For?
PHP is a general-purpose server-side scripting language
originally designed for web development to produce
dynamic web pages
PHP can interact with MySQL databases
3. What is PHP?What is PHP?
PHP == ‘Hypertext Preprocessor’
Open-source, server-side scripting language
Used to generate dynamic web-pages
PHP scripts reside between reserved PHP tags
This allows the programmer to embed PHP scripts within
HTML pages
4. What is PHP (cont’d)What is PHP (cont’d)Interpreted language, scripts are parsed at run-time
rather than compiled beforehand
Executed on the server-side
Source-code not visible by client
‘View Source’ in browsers does not display the PHP code
Various built-in functions allow for fast development
Compatible with many popular databases
5. What does PHP code look like?What does PHP code look like?
Structurally similar to C/C++
Supports procedural and object-oriented paradigm (to
some degree)
All PHP statements end with a semi-colon
Each PHP script must be enclosed in the reserved PHP
tag
<?php
…
?>
6. Comments in PHPComments in PHP
Standard C, C++, and shell comment symbols
// C++ and Java-style comment
# Shell-style comments
/* C-style comments
These can span multiple lines */
7. Variables in PHPVariables in PHP
PHP variables must begin with a “$” sign
Case-sensitive ($Foo != $foo != $fOo)
Global and locally-scoped variables
Global variables can be used anywhere
Local variables restricted to a function or class
Certain variable names reserved by PHP
Form variables ($_POST, $_GET)
Server variables ($_SERVER)
Etc.
9. EchoEcho
The PHP command ‘echo’ is used to output the
parameters passed to it
The typical usage for this is to send data to the client’s
web-browser
Syntax
void echo (string arg1 [, string argn...])
In practice, arguments are not passed in parentheses since
echo is a language construct rather than an actual
function
10. Echo exampleEcho example
Notice how echo ‘5x5=$foo’ outputs $foo rather than replacing it with 25
Strings in single quotes (‘ ’) are not interpreted or evaluated by PHP
This is true for both variables and character escape-sequences (such as “n” or “”)
<?php
$foo = 25; // Numerical variable
$bar = “Hello”; // String variable
echo $bar; // Outputs Hello
echo $foo,$bar; // Outputs 25Hello
echo “5x5=”,$foo; // Outputs 5x5=25
echo “5x5=$foo”; // Outputs 5x5=25
echo ‘5x5=$foo’; // Outputs 5x5=$foo
?>
11. Arithmetic OperationsArithmetic Operations
$a - $b // subtraction
$a * $b // multiplication
$a / $b // division
$a += 5 // $a = $a+5 Also works for *= and /=
<?php
$a=15;
$b=30;
$total=$a+$b;
Print $total;
Print “<p><h1>$total</h1>”;
// total is 45
?>
12. ConcatenationConcatenation
Use a period to join strings into one.
<?php
$string1=“Hello”;
$string2=“PHP”;
$string3=$string1 . “ ” .
$string2;
Print $string3;
?>
Hello PHP
13. Escaping the CharacterEscaping the Character
If the string has a set of double quotation marks that must
remain visible, use the [backslash] before the quotation
marks to ignore and display them.
<?php
$heading=“”Computer Science””;
Print $heading;
?>
“Computer Science”
14. PHP Control StructuresPHP Control Structures
Control Structures: Are the structures within a language that allow
us to control the flow of execution through a program or script.
Grouped into conditional (branching) structures (e.g. if/else) and
repetition structures (e.g. while loops).
Example if/else if/else statement:
if ($foo == 0) {
echo ‘The variable foo is equal to 0’;
}
else if (($foo > 0) && ($foo <= 5)) {
echo ‘The variable foo is between 1 and 5’;
}
else {
echo ‘The variable foo is equal to ‘.$foo;
}
15. If ... Else...If ... Else...
If (condition)
{
Statements;
}
Else
{
Statement;
}
<?php
If($user==“John”)
{
Print “Hello John.”;
}
Else
{
Print “You are not John.”;
}
?>
No THEN in PHP
17. Date DisplayDate Display
$datedisplay=date(“yyyy/m/d”);
Print $datedisplay;
# If the date is April 1st
, 2009
# It would display as 2009/4/1

$datedisplay=date(“l, F m, Y”);
Print $datedisplay;
# If the date is April 1st

19. FunctionsFunctions
Functions MUST be defined before then can be called
Function headers are of the format
Note that no return type is specified
Unlike variables, function names are not case sensitive (foo(…)
== Foo(…) == FoO(…))
function functionName($arg_1, $arg_2, …, $arg_n)
20. Functions exampleFunctions example
<?php
// This is a function
function foo($arg_1, $arg_2)
{
$arg_2 = $arg_1 * $arg_2;
return $arg_2;
}
$result_1 = foo(12, 3); // Store the function
echo $result_1; // Outputs 36
echo foo(12, 3); // Outputs 36
?>

26. Destroy PHP - SessionsDestroy PHP - Sessions
Destroying a Session
why it is necessary to destroy a session when the session will get
destroyed when the user closes their browser. Well, imagine that you
had a session registered called "access_granted" and you were using
that to determine if the user was logged into your site based upon a
username and password. Anytime you have a login feature, to make
the users feel better, you should have a logout feature as well. That's
where this cool function called session_destroy() comes in handy.
session_destroy() will completely demolish your session (no, the
computer won't blow up or self destruct) but it just deletes the session
files and clears any trace of that session.
NOTE: If you are using the $_SESSION superglobal array, you must
clear the array values first, then run session_destroy.
Here's how we use session_destroy():
27. Destroy PHP - SessionsDestroy PHP - Sessions
<?php
// start the session

session_destroy();
echo "<strong>Step 5 - Destroy This Session </strong><br />";
if($_SESSION['name']){
echo "The session is still active";
} else {
echo "Ok, the session is no longer active! <br />";
echo "<a href="page1.php"><< Go Back Step 1</a>";

28. PHP OverviewPHP Overview
Easy learning
Syntax Perl- and C-like syntax. Relatively easy to learn.
Large function library
Embedded directly into HTML
Interpreted, no need to compile
Open Source server-side scripting language designed specifically
for the web.
29. PHP Overview (cont.)PHP Overview (cont.)
Conceived in 1994, now used on +10 million web sites.
Outputs not only HTML but can output XML, images (JPG
& PNG), PDF files and even Flash movies all generated on
the fly. Can write these files to the file system.
Supports a wide-range of databases (20+ODBC).
PHP also has support for talking to other services using
protocols such as LDAP, IMAP, SNMP, NNTP, POP3,
HTTP.

37. History of PHPHistory of PHP
PHP began in 1995 when Rasmus Lerdorf developed a Perl/CGI
script toolset he called the Personal Home Page or PHP
PHP 2 released 1997 (PHP now stands for Hypertex Processor).
Lerdorf developed it further, using C instead
PHP3 released in 1998 (50,000 users)
PHP4 released in 2000 (3.6 million domains). Considered debut of
functional language and including Perl parsing, with other major
features
PHP5.0.0 released July 13, 2004 (113 libraries>1,000 functions with
extensive object-oriented programming)
PHP5.0.5 released Sept. 6, 2005 for maintenance and bug fixes
