The SQL API lets clients create, update and delete containers and items. Items can be queried with a read-only, JSON-friendly SQL dialect. [8] As Cosmos DB embeds a JavaScript engine, the SQL API also enables: Stored procedures. Functions that bundle an arbitrarily complex set of operations and logic into an ACID-compliant transaction. They are ...
-- The logic of PHP mktime is followed where m or d can be zero to mean-- the previous unit, and -1 is the one before that, etc.-- Positive values carry forward. local date if not (1 <= m and m <= 12) then date = Date (y, 1, 1) if not date then return end date = date + ((m-1)..

SQL was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce after learning about the relational model from Edgar F. Codd [12] in the early 1970s. [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 ...

[6] [7] Its name is a combination of "My", the name of co-founder Michael Widenius's daughter My, [1] and "SQL", the acronym for Structured Query Language. A relational database organizes data into one or more data tables in which data may be related to each other; these relations help structure the data. SQL is a language that programmers use ...
Web SQL Database was a prior API developed by Apple. [12] But Firefox refused to add support for it and argued against it becoming a standard because it would codify the quirks of SQLite. [13] [14] It was thus deprecated in favor of IndexedDB. [15] IndexedDB 1.0 became a W3C Recommendation on January 8, 2015. [16]
