OCI方面的知识，哪位高手能帮忙修改下 想批量插入数据，且表的字段很多

/*************************
编译语句
gcc -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -I${ORACLE_HOME}/rdbms/public -I${ORACLE_HOME}/rdbms/demo -L${ORACLE_HOME}/lib -lclntsh  test1.c

OCI重定义数据类型：

typedef unsigned     char         ub1;
typedef signed     char         sb1;
typedef unsigned     short     ub2;
typedef signed     short     sb2;
typedef unsigned     int         ub4;
typedef signed     int         sb4;
typedef ub4                     duword;
typedef sb4                     dsword;
typedef dsword                 dword;
