The SQL:2023 standard (ISO/IEC 9075-2:2023 Information technology — Database languages SQL — Part 2: Foundation (SQL/Foundation), chapter 133) defines an SQL module as an SQL client module, and the language in which SQL queries are called is referred to as the host language. Specified host languages are:
(All the languages listed above are optional features, which means that each vendor can decide which language(s) to support.)
Mimer SQL 11.0 and later for Linux, macOS, OpenVMS and Windows support module SQL for C/C++, and Mimer SQL for OpenVMS also supports module SQL for COBOL, Fortran and Pascal.4
Oracle 8.0 supported SQL*Module for Ada but support has been removed in later versions.5 SQL*Module is a module language that supports the Ada83 language standard for Ada.6
Supported host languages are Ada, BASIC, C, COBOL, Fortran, Pascal and PL/I.7
