SQLの話

SQL has evolved significantly since its inception in 1986. It was originally designed as a data sublanguage for databases but is actually Turing complete. Over the years SQL has gained many capabilities including support for procedural logic, recursion, XML processing and integration with languages like XQuery. Modern databases like PostgreSQL demonstrate SQL's versatility by implementing features like factoring of integers and the functional programming language Grass within SQL queries.

1986 SQL-86 SQL-87 First formalized by ANSI.
1989 SQL-89 FIPS 127-1 Minor revision, adopted as FIPS 127-1.
1992 SQL-92 SQL2, FIPS 127-2 Major revision (ISO 9075), Entry Level SQL-92 adopted as FIPS 127-2.
1999 SQL:1999 SQL3 Added regular expression matching, recursive queries, triggers, support for
procedural and control-of-flow statements, non-scalar types, and some object-
oriented features.
2003 SQL:2003 SQL 2003 Introduced XML-related features, window functions, standardized sequences,
and columns with auto-generated values (including identity-columns).
2006 SQL:2006 SQL 2006 ISO/IEC 9075-14:2006 defines ways in which SQL can be used in conjunction
with XML. It defines ways of importing and storing XML data in an SQL
database, manipulating it within the database and publishing both XML and
conventional SQL-data in XML form. In addition, it enables applications to
integrate into their SQL code the use of XQuery, the XML Query Language
published by the World Wide Web Consortium (W3C), to concurrently access
ordinary SQL-data and XML documents.[29]
2008 SQL:2008 SQL 2008 Legalizes ORDER BY outside cursor definitions. Adds INSTEAD OF triggers.
Adds the TRUNCATE statement.[30]
