Re: connect oracle 10g DB from C language

To use EXEC SQL directives you need to use the PRO*C precompiler before the C compiler.

See http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14407/toc.htm Pro*C/C++ Programmer's Guide 10g Release 2 (10.2)

Reads the introduction first!

If you don't want to use the pre-compiler, you can't use PRO*C directives and embedded SQL - you can use OCI, the Oracle Call Interface, instead - see http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14250/toc.htm.

Certainly, PRO*C is easier to get started with (in my opinion).

Hope that helps

As you suggested, I used the following code in my program:EXEC SQL WHENEVER SQLERROR GOTO error_in_SQL; /* ... */error_in_SQL: /* do error handling */

I got this error:
alpha1.c:12672: error: `EXEC' undeclared (first use in this function)

I also declare the header file: #include <sqlca.h>.

what should i do?? any sugession??
