SQL Is a Database Language:
The commands given to a DBMS by an application are written in the database language of the DBMS. The term data sublanguage is sometimes used instead of database language. The sub- prefix refers to the fact that application programs are sometimes written in some more general-purpose programming language (the "host" language), in which the database language commands are embedded in some prescribed style. Sometimes the embedding style is such that the embedded statements are unrecognized by the host language compiler or interpreter, and some special preprocessor is used to replace the embedded statements by, for example, CALL statements in the host language.Those remarks apply to SQL, as does the remainder of that section. Moreover, Part 10 of the international standard for SQL defines classes for use in object-oriented languages, in particular, Java, thus allowing method invocations to be used in place of old-fashioned CALL statements.
