SODA for C is an integral part of Oracle Call Interface (OCI) starting with Oracle Database Release 18c (18.3).
To use SODA for C, ensure the following:
You have Oracle Call Interface 18.3 or later.
You have Oracle Database 18c or later. To use indexing you need release 18.3 or later.
It is not a requirement, but Oracle recommends that you use AL32UTF8, which implements Unicode UTF-8, as the database character set.
You compile programs that use SODA for C the same way you compile other OCI programs.
