Re: How-to access ORACLE from Ansi-C?

In addition to Pro*C, which does support ANSI-C, you can use the Oracle Call Interface (OCI). It does not use a precompiler step, like pro*C, and is a "native interface" to Oracle.

I use pro*c and find it easy to maintain and it works quite well. Others like OCI because it is purported to be faster than Pro*c precompiled code. I don't know if this is true. I do know that the resulting Pro*c precompiled code does not call the same Oracle libraries that the OCI calls. If I remember correctly, the Pro*c calls the same Oracle libraries that Oracle applications calls.

cheers.
