Module SQL is a method of combining the computing power of a programming language and the database manipulation capabilities of SQL. Module SQL statements are SQL statements written in an SQL client module, that can be called as routines from the host language program source code like a host language routine. An SQL standard Module Language file is compiled into calls to a SQL runtime library that interacts with the Database management system. This allows programmers to call SQL statements from programs written in any number of languages such as C/C++, Ada, COBOL and Fortran.
Using Module Language is very straightforward: place all SQL code in a separate module, and define an interface between the module containing the SQL code and the host program. [1] The SQL standard 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. A popular host language is C.
