Reason to explain these performances of odbc and occi...

767844Apr 20 2010 — edited Apr 21 2010

I wrote some simple test programs to compare the performances of odbc and occi accessing Oracle.
These programs were wrote in C++. The occi and odbc were given under almost the same circumstance.
The result is: when executing query(simple select) the odbc is fast than occi. When executing insert sentences, the occi is much more fast than odbc does.
My computer environment: Oracle 10g, Oracle instant cilent, VS 8.0.
Do they all access oracle through OCI interface? How to explain the result?
Someone give me some hints , please.
