oracle - What is pro *c? -

-

how useful? how can access data database?

pro*c pre-compiler oracle database access within c code.

you write code statements like:

int sal; exec sql select salary :sal employees name = 'diablo, pax'; if (sal < 100000)     printf ("i'm not being paid enough!\n");

intermixing regular c pro*c statements (as can see) , run through pro*c compiler.

what comes out of c program has pro*c statements replaced equivalent function calls same thing.

you run through real c compiler , gives executables run perform whatever tasks want.
