The Current Edition of ISO/IEC 9075 for SQL If you don’t want to read all the history on SQL that we’ve detailed below, to make things short, SQL was standardized in ANSI X3.135 in 1986, and, within a few months, it was adopted by ISO as ISO 9075-1987. While most vendors modify SQL to meet their needs, they generally base their programs off the current version of this standard. The international standard (now ISO/IEC 9075) has been revised periodically ever since, most recently in 2016. It exists in 9 parts:

• ISO/IEC 9075-1:2016 – Information technology – Database languages – SQL – Part 1: Framework (SQL/Framework)
• ISO/IEC 9075-2:2016 – Information technology – Database languages – SQL – Part 2: Foundation (SQL/Foundation)
• ISO/IEC 9075-3:2016 – Information technology – Database languages – SQL – Part 3: Call-Level Interface (SQL/CLI)
• ISO/IEC 9075-4:2016 – Information technology – Database languages – SQL – Part 4: Persistent stored modules (SQL/PSM)
• ISO/IEC 9075-9:2016 – Information technology – Database languages – SQL – Part 9: Management of External Data (SQL/MED)
• ISO/IEC 9075-10:2016 – Information technology – Database languages – SQL – Part 10: Object language bindings (SQL/OLB)
• ISO/IEC 9075-11:2016 – Information technology – Database languages – SQL – Part 11: Information and definition schemas (SQL/Schemata)
• ISO/IEC 9075-13:2016 – Information technology – Database languages – SQL – Part 13: SQL Routines and types using the Java TM programming language (SQL/JRT)
• ISO/IEC 9075-14:2016 – Information technology – Database languages – SQL – Part 14: XML-Related Specifications (SQL/XML)
