Could anyone inform me as to what these two languages are and how they
relate to ORACLE database systems development. Also how do they differ from
'c' and COBOL.

Thanks

Pro*C and Pro*COBOL are not languages. They are pre-compilers. What
they do is take embedded SQL statements and translate them into calls to
library routines. This is to allow access to an Oracle database from these
languages.

Hi David

Pro*C and Pro*Cobol are ORACLE's "pre-compiler" languages.
They are "pre-compilers" because they "compile" embedded SQL
statements into "true" C or COBOL code so that you can then
use the normal C or COBOL compilers.

It's supposed to be simpler than using the low-level (function)
call interface. A Pro*C source might look like this:

main ()
{
EXEC BEGIN DECLARE SECTION;
employee_name CHAR[21];
EXEC END DECLARE SECTION;

EXEC SQL SELECT ename INTO employee_name FROM EMP
WHERE empid = 1234;

printf ("\nName=%s", employee_name);

Quote:}

The PRO*C precompiler would convert the statements beginning
with EXEC to C code so you can compile with a standard C
compiler.

Pro*C and Pro*Cobol are the Oracle precompilers to convert embedded SQL to
host language statements (that is C or Cobol code) for the actual compiler.
