SQLAlchemy is an open-source Python library that provides an SQL toolkit (called "SQLAlchemy Core") and an Object Relational Mapper (ORM) for database interactions. It allows developers to work with databases using Python objects, enabling efficient and flexible database access.
Shorthand may also be used, taking advantage of the order of the columns when the table was created. It is not required to specify all columns in the table since any other columns will take their default value or remain null: INSERT INTO table VALUES (value1, [value2, ...
It is designed for the dissemination of information, such as newsletters, news, advertising to list of subscribers. It is written in PHP and uses a MySQL database to store the information. phpList is free and open-source software subject to the terms of the GNU Affero General Public License (AGPL).

[13] This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM's original quasirelational database management system, System R, which a group at IBM San ...
Date table sorting is used to correctly sort and display dates in a sortable table (see Help:Sortable tables). What it solves Dates in their customary formats, if simply treated as alphanumeric text strings, sort in nonsensical ways:
[17] The separator used between date values (year, month, week, and day) is the hyphen, while the colon is used as the separator between time values (hours, minutes, and seconds). For example, the 6th day of the 1st month of the year 2009 may be written as "2009-01-06" in the extended format or as "20090106" in the basic format without ambiguity.
Word2vec is a technique in natural language processing (NLP) for obtaining vector representations of words. These vectors capture information about the meaning of the word based on the surrounding words.
A common exception is a series of values: The distances were 1 + 1 ⁄ 4, 2 ⁄ 3 and 1 ⁄ 2 mile, respectively. Mixed numbers may be given in figures or words (perhaps applying the guidance above to the integer part).
