CHAPTER3Embedded SQLOracle SQL, introduced in the previous chapter, is not a language that can beused to build sophisticated database applications, but it is a very good languagefor defining the structure of the database and generating ad hoc queries. However,to build applications, the power of a full-fledged high-level programming languageis needed. Embedded SQL provides such an environment to develop applicationprograms. The basic idea behind Embedded SQL is to allow SQL statements ina program written in a high-level programming language such as C or C++.Byembedding SQL statements in a C/C++program, one can now write applicationprograms in C/C++that interact (read and write) with the database.
